The big, bad book of botany
\"David Attenborough meets Lemony Snicket in The Big Bad Book of Botany, Michael Largo's entertaining and enlightening one-of-a-kind compendium of the world's most amazing and bizarre plants, their history, and their lore. The Big, Bad Book of Botany introduces a world of wild, wonderful, and weird plants. Some are so rare, they were once more valuable than gold. Some found in ancient mythology hold magical abilities, including the power to turn a person to stone. Others have been used by assassins to kill kings, and sorcerers to revive the dead. Here, too, is vegetation with astonishing properties to cure and heal, many of which have long since been lost with the advent of modern medicine. Organized alphabetically, The Big, Bad Book of Botany combines the latest in biological information with bizarre facts about the plant kingdom's oddest members, including a species that is more poisonous than a cobra and a prehistoric plant that actually 'walked.' Largo takes you through the history of vegetables and fruits and their astonishing agricultural evolution. Throughout, he reveals a astonishing facts, from where the world's first tree grew to whether plants are telepathic. Featuring more than 150 photographs and illustrations, The Big, Bad Book of Botany is a fascinating, fun A-to-Z encyclopedia for all ages that will transform the way we look at the natural world.\"--from publisher's description.

The Kew plant glossary : an illustrated dictionary of plant terms
\"Kew's highly acclaimed plant dictionary clearly defines 4,905 entries used by botanists to describe plants in textbooks, scientific papers, floras and field guides. This second edition includes 400 new terms including a section of vegetation types, and more than 730 entries are illustrated with detailed line drawings as well as 32 plates of grouped terms. The Kew Plant Glossary provides an essential reference for students, teachers, researchers, conservationists, horticulturalists, agriculturalists and gardeners.\" --Cover.

Why do plants produce so many terpenoid compounds?
All plants synthesize a suite of several hundred terpenoid compounds with roles that include phytohormones, protein modification reagents, anti-oxidants, and more. Different plant lineages also synthesize hundreds of distinct terpenoids, with the total number of such specialized plant terpenoids estimated in the scores of thousands. Phylogenetically restricted terpenoids are implicated in defense or in the attraction of beneficial organisms. A popular hypothesis is that the ability of plants to synthesize new compounds arose incrementally by selection when, as a result of gradual changes in their biotic partners and enemies, the ‘old’ plant compounds were no longer effective, a process dubbed the ‘coevolutionary arms race’. Another hypothesis posits that often the sheer diversity of such compounds provides benefits that a single compound cannot. In this article, we review the unique features of the biosynthetic apparatus of terpenes in plants that facilitate the production of large numbers of distinct terpenoids in each species and how facile genetic and biochemical changes can lead to the further diversification of terpenoids. We then discuss evidence relating to the hypotheses that given ecological functions may be enhanced by the presence of mixtures of terpenes and that the acquisition of new functions by terpenoids may favor their retention once the original functions are lost.

Reaching for the sun : how plants work
\"From their ability to use energy from sunlight to make their own food, to combating attacks from diseases and predators, plants have evolved an amazing range of life-sustaining strategies. Written with the non-specialist in mind, John King's lively natural history explains how plants function, from how they gain energy and nutrition to how they grow, develop and ultimately die. New to this edition is a section devoted to plants and the environment, exploring how problems created by human activities, such as global warming, pollution of land, water and air, and increasing ocean acidity, are impacting on the lives of plants. King's narrative provides a simple, highly readable introduction, with boxes in each chapter offering additional or more advanced material for readers seeking more detail. He concludes that despite the challenges posed by growing environmental perils, plants will continue to dominate our planet\"-- Provided by publisher.

An integrated assessment of the vascular plant species of the Americas
The cataloging of the vascular plants of the Americas has a centuries-long history, but it is only in recent decades that an overview of the entire flora has become possible. We present an integrated assessment of all known native species of vascular plants in the Americas. Twelve regional and national checklists, prepared over the past 25 years and including two large ongoing flora projects, were merged into a single list. Our publicly searchable checklist includes 124,993 species, 6227 genera, and 355 families, which correspond to 33% of the 383,671 vascular plant species known worldwide. In the past 25 years, the rate at which new species descriptions are added has averaged 744 annually for the Americas, and we can expect the total to reach about 150,000.

The nature of plants : an introduction to how plants work
\"Ecologist and nursery owner Craig Huegel demystifies the complex lives of plants and [examines] their inner and outer workings. Beginning with the importance of light, water, and soil, Huegel describes photosynthesis, plant circadian rhythms, and how best to position plants to receive optimal sunlight. [Among other subjects, he then] explains choosing artificial lights for landscaping, giving lucky bamboo its twisted shape and tricking flowers like poinsettias to bloom at a specific time of year\"--Back cover.

One thousand plant transcriptomes and the phylogenomics of green plants
Green plants (Viridiplantae) include around 450,000-500,000 species
of great diversity and have important roles in terrestrial and aquatic ecosystems. Here, as part of the One Thousand Plant Transcriptomes Initiative, we sequenced the vegetative transcriptomes of 1,124 species that span the diversity of plants in a broad sense (Archaeplastida), including green plants (Viridiplantae), glaucophytes (Glaucophyta) and red algae (Rhodophyta). Our analysis provides a robust phylogenomic framework for examining the evolution of green plants. Most inferred species relationships are well supported across multiple species tree and supermatrix analyses, but discordance among plastid and nuclear gene trees at a few important nodes highlights the complexity of plant genome evolution, including polyploidy, periods of rapid speciation, and extinction. Incomplete sorting of ancestral variation, polyploidization and massive expansions of gene families punctuate the evolutionary history of green plants. Notably, we find that large expansions of gene families preceded the origins of green plants, land plants and vascular plants, whereas whole-genome duplications are inferred to have occurred repeatedly throughout the evolution of flowering plants and ferns. The increasing availability of high-quality plant genome sequences and advances in functional genomics are enabling research on genome evolution across the green tree of life.

The biomass distribution on Earth
A census of the biomass on Earth is key for understanding the structure and dynamics of the biosphere. However, a global, quantitative view of how the biomass of different taxa compare with one another is still lacking. Here, we assemble the overall biomass composition of the biosphere, establishing a census of the ≈550 gigatons of carbon (Gt C) of biomass distributed among all of the kingdoms of life. We find that the kingdoms of life concentrate at different locations on the planet; plants (≈450 Gt C, the dominant kingdom) are primarily terrestrial, whereas animals (≈2 Gt C) are mainly marine, and bacteria (≈70 Gt C) and archaea (≈7 Gt C) are predominantly located in deep subsurface environments. We show that terrestrial biomass is about two orders of magnitude higher than marine biomass and estimate a total of ≈6 Gt C of marine biota, doubling the previous estimated quantity. Our analysis reveals that the global marine biomass pyramid contains more consumers than producers, thus increasing the scope of previous observations on inverse food pyramids. Finally, we highlight that the mass of humans is an order of magnitude higher than that of all wild mammals combined and report the historical impact of humanity on the global biomass of prominent taxa, including mammals, fish, and plants.
