Solanaceous vegetable crops are cultivated and consumed worldwide. However, they often confront diverse abiotic stresses that significantly impair their growth, yield, and overall quality. This review delves into melatonin and abscisic acid (ABA) biosynthesis and their roles in abiotic stress responses. It closely examines the intricate interplay between melatonin and ABA in managing stress within plants, revealing both collaborative and antagonistic effects and elucidating the underlying molecular mechanisms. Melatonin and ABA mutually influence each other’s synthesis, metabolism and that of other plant hormones, a key focus of this study. The study highlights melatonin’s role in aiding stress management through ABA-dependent pathways and key genes in the melatonin-ABA interaction. Specifically, melatonin downregulates ABA synthesis genes and upregulates catabolism genes, leading to reduced ABA levels. It also directly scavenges H 2 O 2 , enhancing antioxidant enzyme activities, thereby underscoring their collaborative role in mediating stress responses. Moreover, the interplay between melatonin and ABA plays an essential role in multiple physiological processes of plants, including stomatal behaviors, wax accumulation, delay leaf senescence, seed germination, and seedlings growth, among others. Recognizing these relationships in Solanaceae vegetable crops holds great importance for improving agricultural practices and crop quality. In summary, this review offers a comprehensive overview of recent studies on the melatonin and ABA interplay, serving as a valuable resource for researchers and breeders dedicated to fortifying crop resilience and productivity within challenging environments.

In response to the pressing need to re-constitute the ways we live with non-humans, more-than-human geography's distinctive contribution has been to describe an ethics based not on 'certain subjects' but on the relational entanglement of life: to show that 'we' are connected and thus invited to care. This paper aims to suggest, however, that this relational diagnostic obscures as much as it reveals and that detachment, as much as relation, provides an everyday ethic that can accommodate more-than-human difference. I do this by analysing how life is stuck together and pulled apart in the British domestic garden, drawing on life history interviews and 'show me your garden' walking tours with experienced gardeners. The article is aligned with a widening bestiary of companion species in geography, and considers the appearances and disappearances of a domestic monster: the slug. Therefore in contrast to existing literature the paper explores gardening's darker aspects. First, I describe how slugs and gardeners are 'sticky': joined together by shared histories, curiosity and disgust. The paper then shifts to examine how gardeners practice detachment: distancing themselves from the act of killing slugs but yet avowing the violence of their actions; acknowledging the limits of their capacities to bend space to their will and imagination; recognising the vulnerability of slugs, and being transformed by that recognition. The analysis shows first, that the emphasis on gathering together and relationality obscures what lies outside relations, and second how detachment emerges not as the negation, but as an enabling constituent of more-than-human ethics. In conclusion the paper argues for looser mappings of relationality and ethics that attend more fully to the distance between species.

What is the impact of garden-based learning on academic outcomes in schools? To address this question, findings across 152 articles (1990–2010) were analyzed resulting in 48 studies that met the inclusion criteria for this synthesis. A review template with operational coding framework was developed. The synthesis results showed a preponderance of positive impacts on direct academic outcomes with the highest positive impact for science followed by math and language arts. Indirect academic outcomes were also measured with social development surfacing most frequently and positively. These results were consistent across programs, student samples, and school types and within the disparate research methodologies used. However, a common issue was lack of research rigor as there were troubling issues with incomplete descriptions of methodological procedures in general and sampling techniques and validity in particular. Recommendations for more systematic and rigorous research are provided to parallel the growing garden-based education movement.

The scale and nature of early cultivation are topics that have received relatively limited attention in research on the origins of agriculture. In Southwest Asia, one the earliest centers of origin worldwide, the transition to food production is commonly portrayed as a macroevolutionary process from hunter-gatherer through to cultivator-forager and farming stages. Climate change, resource intensification, sedentism, rising population densities, and increasing social complexity are widely considered by prehistorians as pivotal to the emergence of protoagricultural village life. In this paper we revisit these narratives that have been influenced by culture-history and social evolution, together forming the dominant theoretical paradigms in the prehistory of Southwest Asia. We propose a complementary contextual approach seeking to reconstruct the historical development of Early Holocene plant-food production and its manifold sociocultural environments by intersecting multiple lines of evidence on the biology of plant domestication, resource management strategies, settlement patterns, cultivation and harvesting technologies, food storage, processing and consumption, ritual practices and symbolic behaviors. Furthermore, we propose that early plant-food production in Southwest Asia should be dissociated from ethnographically derived notions of sedentary village life. Plants emerge as important components of community interactions and ritual performances involving suprahousehold groups that were mediated through communal food consumption.

Private gardens collectively comprise the largest green space in most cities and the greatest potential for increasing the extent of wildlife-friendly and native-dominated habitat, improving the quality of ecosystem services, and providing opportunities for urban dwellers to reconnect with nature. Because attitudes and values driving landscape preferences in gardens are complex and often not conducive to biodiversity, and a gap exists between the possession of knowledge or values and the expression of pro-environmental behavior, facilitating change in gardening behavior is challenging. We attempted to improve knowledge and influence values, attitudes, and gardening behavior of 55 householders in favor of native biodiversity and environmentally friendly practices, through a two-way communication process, or interactive dialog, during a process of biodiversity documentation of their gardens. Informative feedback on their garden with a normative component was also provided. Despite being well educated and knowledgeable about common species at the start of the study, an increase in knowledge and shift in attitude was detected in 64% of householders: 40% reported a greater understanding of wildlife, and 26% made changes in their gardens, 13% to support native biodiversity. The normative component of our feedback information was of particular interest to 20% of householders. Because neighborhood norms influence gardening practices, changes adopted by a proportion of householders should be perpetuated across neighborhoods. The process of biodiversity assessment, dialog, and feedback was effective in improving knowledge of wildlife and native species, and stimulated a shift in attitude that resulted in native-friendly gardening practices. These changes were detected primarily through open self-report questions, rather than quantitative measures.

In an increasingly urban society, city residents are finding innovative ways of stewarding nature that integrate environmental, community, and individual outcomes. These urban civic ecology practices - including community gardening, shellfish reintroductions, tree planting and care, and \"friends of parks\" initiatives to remove invasive and restore native species - generally begin as small, self-organized efforts after a prolonged period of economic and environmental decline or more sudden major disruptions, such as earthquakes, hurricanes, and conflict. Those practices that are sustained expand to encompass partnerships with non-profit organizations; local-, state-, and federal-level government agencies; and universities. Civic ecology practices reflect local cultures and environments as well as the practical knowledge of city residents, and thus vary widely across different cities. When viewed as local assets in some of the most densely populated urban neighborhoods, civic ecology practices offer opportunities for scientific and policy partnerships that address the Ecological Society of America's important Earth Stewardship initiative.

We are concerned that the IS research community is making the discipline's central identity ambiguous by, all too frequently, under-investigating phenomena intimately associated with IT-based systems and over-investigating phenomena distantly associated with IT-based systems. In this commentary, we begin by discussing why establishing an identity for the IS field is important. We then describe what such an identity may look like by proposing a core set of properties, i.e., concepts and phenomena, that define the IS field. Next, we discuss research by IS scholars that either fails to address this core set of properties (labeled as error of exclusion) or that addresses concepts/phenomena falling outside this core set (labeled as error of inclusion). We conclude by offering suggestions for redirecting IS scholarship toward the concepts and phenomena that we argue define the core of the IS discipline.

Early civilization has been envisioned as a child of agriculture, a product of the Neolithic revolution proposed by V. Gordon Childe. However, archaeological and ethnographic records worldwide are replete with complex hunter-gatherers who rely on both wild and domesticated resources. Researchers now recognize that mixed or largely nonagricultural subsistence practices frequently supported sedentary groups and larger complex societies before agriculture dominated subsistence around the world. This article builds on a mixed/nonagricultural model proposed by several authors for one of Mesoamerica’s earliest complex societies, the Early Formative Olmec (1200–400 BC) of Mexico’s southern Gulf Coast lowlands. Presentation of the nonagricultural model seeks to expand the lexicon of early subsistence in the tropical lowlands and introduces mixed subsistence hunter-fisher-gardeners for the early Gulf Coast lowlands in the millennia before the Olmec proper. Paleobotanical evidence of maize and Early Formative artifact assemblages are examined for goodness of fit with the mixed model at the Formative Olmec centers of San Lorenzo Tenochtilan and La Venta and related sites in Veracruz and Tabasco, Mexico. Available data strongly recommend further testing of the nonagricultural model in the southern Gulf Coast lowlands and beyond.

Our aim was to explore the use of practice theory as an approach to studying urban environmental stewardship. Urban environmental stewardship, or civic ecology practice, contributes to ecosystem services and community well-being and has been studied using social-ecological systems resilience, property rights, communities of practice, and governance frameworks. Practice theory, which previously has been applied in studies of consumer behaviors, adds a new perspective to urban stewardship research, focusing on how elements of a practice, such as competencies, meanings, and physical resource, together define the practice. We applied practice theory to eight different civic ecology practices, including oyster gardening in New York City, a civil society group engaged in litter cleanup in Iran, and village grove restoration in South Korea. Our analysis suggests that in applying practice theory to the civic ecology context, consideration should be given to social and communication competencies, how meanings can motivate volunteers and sustain practice, and the nature of the resource that is being stewarded. Future studies may want to focus on how practice elements interact within and vary across practices and may be used to more systematically analyze and share ideas among diverse civic ecology practices.

Despite an emerging literature on guerrilla gardening as a political practice in public spaces, with few exceptions, these accounts theorise it as working against many corporate and bureaucratic forms of power. Using the example of 'F Troop'—a group of gardeners operating on a site in an English midland city—this paper focuses on the practices of urban guerrilla gardening in order to illustrate that these are perhaps not as 'resistant' or 'celebratory' as previous accounts have suggested. Rather, this paper draws on ethnographic data to focus attention on the micro politics of garden activism, arguing that the social backgrounds and motivations of those involved in guerrilla gardening and their relationship with other users of the space surrounding the dig site are also important—but largely underacknowledged—aspects of guerrilla gardening.
