“…2 Genes of the Asr (ABA, stress, ripening) family were initially characterized by their strong induction under stress conditions and during tomato fruit ripening. 3,4 Their members harbor the ABA/WDS (abscisic acid/water deficit stress) domain (Pfam entry PF02496) as a common denominator. This protein family is widely distributed in the Plantae kingdom, both in angiosperms and in gymnosperms, but not in all species.…”

“…13,31 However, ASR1 is also expressed under many other physiological conditions, such as tomato and strawberry fruit ripening. 3,4,15 This indicates that ASR1 may have other functions beyond its role in stress. More than a decade ago,Çakir et al 17 proved that a grape ASR1 ortholog called MSA recognizes specific sites in the regulatory region of the hexose transporter 1 gene (Ht1 is described in Hayes et al 37 Vignault et al 38 and Fillion et al).…”

“…Zinc finger protein 1 (ThZF1) from Thellungiella showed involvement in drought and salt stress (Xu et al, 2007). (ASR1) was first cloned from tomato encoding a highly charged 13-kDa protein (Iusem et al, 1993) and thereafter isolated from several plant species of dicotyledonous and monocotyledonous plants (Maskin et al, 2001;Carrari et al, 2004). Being developmentally regulated during fruit ripening this gene has also shown the expression in both salt and drought.…”

Identification of salt-induced genes from Salicornia brachiata, an extreme halophyte through expressed sequence tags analysis

Salinity severely affects plant growth and development causing crop loss worldwide. We have isolated a large number of salt-induced genes as well as unknown and hypothetical genes from Salicornia brachiata Roxb. (Amaranthaceae). This is the first description of identification of genes in response to salinity stress in this extreme halophyte plant. Salicornia accumulates salt in its pith and survives even at 2 M NaCl under field conditions. For isolating salt responsive genes, cDNA subtractive hybridization was performed between control and 500 mM NaCl treated plants. Out of the 1200 recombinant clones, 930 sequences were submitted to the NCBI database (GenBank accession: EB484528 to EB485289 and EC906125 to EC906292). 789 ESTs showed matching with different genes in NCBI database. 4.8% ESTs belonged to stress-tolerant gene category and approximately 29% ESTs showed no homology with known functional gene sequences, thus classified as unknown or hypothetical. The detection of a large number of ESTs with unknown putative function in this species makes it an interesting contribution. The 90 unknown and hypothetical genes were selected to study their differential regulation by reverse Northern analysis for identifying their role in salinity tolerance. Interestingly, both up and down regulation at 500 mM NaCl were observed (21 and 10 genes, respectively). Northern analysis of two important salt tolerant genes, ASR1 (Abscisic acid stress ripening gene) and plasma membrane H + ATPase, showed the basal level of transcripts in control condition and an increase with NaCl treatment. ASR1 gene is made full length using 5' RACE and its potential role in imparting salt tolerance is being studied.

“…Since their discovery more than a decade ago, they have been described as accumulating to high levels during plant developmental processes, such as fruit ripening, pollen maturation, and Glc metabolism (Iusem et al, 1993;Wang et al, 1998;Cakir et al, 2003;Frankel et al, 2007;Yang et al, 2008), and in response to diverse stresses, including water deficit, salt, cold, limited light, and, lately, pathogen attack (Schneider et al, 1997;Riccardi et al, 1998;Vaidyanathan et al, 1999;Huang et al, 2000;Maskin et al, 2001;Kalifa et al, 2004b;Liu et al, 2010;Philippe et al, 2010;Henry et al, 2011). Nevertheless, it is noteworthy that their exact function remains enigmatic.…”

The ZmASR1 Protein Influences Branched-Chain Amino Acid Biosynthesis and Maintains Kernel Yield in Maize under Water-Limited Conditions

et al. 2011

Abscisic acid-, stress-, and ripening-induced (ASR) proteins were first described about 15 years ago as accumulating to high levels during plant developmental processes and in response to diverse stresses. Currently, the effects of ASRs on water deficit tolerance and the ways in which their physiological and biochemical functions lead to this stress tolerance remain poorly understood. Here, we characterized the ASR gene family from maize (Zea mays), which contains nine paralogous genes, and showed that maize ASR1 (ZmASR1) was encoded by one of the most highly expressed paralogs. Ectopic expression of ZmASR1 had a large overall impact on maize yield that was maintained under water-limited stress conditions in the field. Comparative transcriptomic and proteomic analyses of wild-type and ZmASR1-overexpressing leaves led to the identification of three transcripts and 16 proteins up-or down-regulated by ZmASR1. The majority of them were involved in primary and/or cellular metabolic processes, including branched-chain amino acid (BCAA) biosynthesis. Metabolomic and transcript analyses further indicated that ZmASR1-overexpressing plants showed a decrease in BCAA compounds and changes in BCAA-related gene expression in comparison with wild-type plants. Interestingly, within-group correlation matrix analysis revealed a close link between 13 decreased metabolites in ZmASR1-overexpressing leaves, including two BCAAs. Among these 13 metabolites, six were previously shown to be negatively correlated to biomass, suggesting that ZmASR1-dependent regulation of these 13 metabolites might contribute to regulate leaf growth, resulting in improvement in kernel yield.
