Avenues for improving drought tolerance in crops by ABA regulation [link]Paper  doi  abstract   bibtex   
Crop productivity is greatly reduced due to abiotic stresses including drought stress. Naturally occurring drought stress tolerant plants have evolved some adaptations to cope with drought stress. Based on drought adaptive responses in wild or crop plants, plant scientists are pursuing efforts to develop crop tolerance against drought stress using heritable traits that contribute in drought tolerance through conventional or advanced molecular techniques. Among these drought tolerance traits, organic compatible solutes, antioxidant compounds, and plant growth regulators are of great significance. Among various plant growth regulators, abscisic acid (ABA) is known to regulate environmental stress responses in plants by affecting transpirational water loss, stomatal closure, photosynthesis, water use efficiency, seed development and maturation, leaf senescence and cell membrane protection, and so on. The degree of biosynthesis and accumulation of ABA in a crop cultivar is a possible indicator of drought tolerance. Drought stress-regulated ABA biosynthesis depends on a key enzyme, 9-cis-epoxycarotenoid dioxygenase (NCED) involved in ABA biosynthesis. NCED3 and/or its corresponding orthologs could be valuable targets for improving drought tolerance in crops. In all ABA-dependent physiological and developmental processes, regulation of ABA signaling is central to develop drought tolerance in plants. A number of drought tolerance related functional and regulatory genes that are regulated by ABA have been discovered, of which bZIP transcription factors (TFs), ABI5, AREB/ABFs, SnRK2-AREB/ABF, and WRKY are of key importance. However, impact of these genes in developing drought tolerance is confounded in some cases because drought tolerance mechanism is very complex and varies with plant developmental stage. In addition, an ABA-independent pathway for drought tolerance also exists in plants, which causes further complexity in understanding the mechanisms of drought tolerance. Finding missing links in sensing and response components of ABA signaling cascades using a wide range of high-throughput analytical techniques for measuring metabolites, proteins, and transcripts in plant tissues will pave new avenues for studying stress resistance in crops.
