Beyond osmolytes and transcription factors: drought tolerance in plants via protective proteins and aquaporins

Abstract: Mechanisms of drought tolerance have been studied by numerous groups, and a broad range of molecules have been identified to play important roles. A noteworthy response of stressed plants is the accumulation of novel protective proteins, including heat-shock proteins (HSPs) and late embryogenesis abundant (LEA) proteins. Identification of gene regulatory networks of these protective proteins in plants will allow a wide application of biotechnology for enhancement of drought tolerance and adaptation. Similarly,… Show more

“…Different plant AQPs have different substrate specificities, localization, as well as transcriptional and posttranslational regulations [ 17 , 18 ]. Depending on membrane localization and amino acid sequence, AQPs in higher plants are classified into five subfamilies [ 19 ] including plasma membrane intrinsic proteins (PIPs), tonoplast intrinsic proteins (TIPs), nodulin-26 like intrinsic proteins (NIPs), small basic intrinsic proteins (SIPs), and X intrinsic proteins/uncharacterized-intrinsic proteins (XIPs) [ 20 22 ]. Plant species typically have a higher number of AQP genes than animals, ranging from 30 to 70 [ 4 , 18 , 23 ].…”

“…At the biochemical level, dehydration-tolerant plants are characterized by: (1) more effective identification and transduction of signals (including ABA) (Cutler et al 2010;Pantin et al 2013); (2) more efficient systems of protein repair or proteolytic removal (Grudkowska and Zagdańska 2004); (3) better protection of cell membranes by osmoprotectants (Iturriaga et al 2009;Zhang et al 2009); (4) the existence of LEA proteins (abundant late embryogenesis) interacting primarily with trehalose (Iturriaga 2008;Caramelo and Iusem 2009;Hussain et al 2011); (5) more stable photosynthesis (Jaleel et al 2009; Pinheiro and Chaves 2011); (6) more stable mitochondria metabolism (Atkin and Macherel 2009;Zagdańska, 1997); and (7) more stable tissue oxidation-reduction potential sustained by mechanisms inhibiting generation of free radicals as well as by their effective inactivation (Miller et al 2010).…”

“…To cope with environmental stresses, plants activate a large set of genes, which lead to the accumulation of specific stress-associated proteins (reviewed in [253]). The stomatal limitation on photosynthesis imposed by the earlier stages of water deficit (WD) result in a decrease of primary electron acceptors available for photochemistry [47].…”
