Journal Article
A transcriptome-wide identification of ATP-binding cassette (ABC) transporters revealed participation of ABCB subfamily in abiotic stress management of Glycyrrhiza glabra L
2024
Overview
Transcriptome-wide survey divulged a total of 181 ABC transporters in
G. glabra
which were phylogenetically classified into six subfamilies. Protein–Protein interactions revealed nine putative GgABCBs (-B6, -B14, -B15, -B25, -B26, -B31, -B40, -B42 &-B44) corresponding to five AtABCs orthologs (-B1, -B4, -B11, -B19, &-B21). Significant transcript accumulation of
ABCB6
(31.8 folds), -
B14
(147.5 folds), -
B15
(17 folds),
-B25
(19.7 folds), -
B26
(18.31 folds),
-B31
(61.89 folds),
-B40
(1273 folds) and -
B42
(51 folds) was observed under the influence of auxin. Auxin transport-specific inhibitor, N-1-naphthylphthalamic acid, showed its effectiveness only at higher (10 µM) concentration where it down regulated the expression of
ABCBs
,
PINs
(PIN FORMED) and
TWD1
(TWISTED DWARF 1) genes in shoot tissues, while their expression was seen to enhance in the root tissues. Further, qRT-PCR analysis under various growth conditions (
in-vitro
, field and growth chamber), and subjected to abiotic stresses revealed differential expression implicating role of
ABCBs
in stress management. Seven of the nine genes were shown to be involved in the stress physiology of the plant.
GgABCB6
,
15
,
25
and
ABCB31
were induced in multiple stresses, while
GgABCB26
,
40
&
42
were exclusively triggered under drought stress. No study pertaining to the ABC transporters from
G. glabra
is available till date. The present investigation will give an insight to auxin transportation which has been found to be associated with plant growth architecture; the knowledge will help to understand the association between auxin transportation and plant responses under the influence of various conditions.
