“…Sorbitol dehydrogenase encoded by the PmSDH1 gene over-accumulates mannitol to regulate salt stress in transgenic Plantago major plants [7]. Similarly, some transcriptional factors, such as OsNAC5 and JERF3 in rice and TaSTRG in wheat, can regulate stress responses and transgenic plants had improved tolerance to abiotic stresses such as salt, drought and cold [15,16]. Despite these examples, salinity response remains a very complicated quantitative trait, causing many proteins to undergo removal of signal peptides, RNA splicing and post-translational modifications (PTMs) such as phosphorylation and glycosylation.…”

“…The best characterized TF groups are ABA responsive element binding protein1 (AREB1), ABA responsive binding factor 2 (ABF2), dehydration-responsive binding protein (DREB) genes, MYB genes, bZIP encoding genes and the protein kinases such as receptor like kinase 1, SNF1-related protein kinase 2C or guard cell expressing calcium dependent protein kinases (Choi et al 2000; Osakabe et al 2005; Umezawa et al 2004; Uno et al 2000). Many TF genes have been used to produce transgenic rice lines with either constitutive or inducible promoters, such as HvCBF4 (Oh et al 2007), AP37 (Oh et al 2009), TaSTRG (Zhou et al 2009), ERF protein TSRF1 (Quan et al 2010), ERF protein JERF3 (Zhang et al 2010), OsDREB2A with the 4ABRC promoter (Cui et al 2011), OsDREB2A with the rd29A promoter (Mallikarjuna et al 2011), SbDREB2 (Bihani et al 2011), OsSD1R1 (Gao et al 2011), OsDREB1A , OsDREB1B and AtDREB1A (Datta et al 2012). …”

Stress-inducible expression of AtDREB1A transcription factor greatly improves drought stress tolerance in transgenic indica rice

et al. 2014

The cultivation of rice (Oryza sativa L.), a major food crop, requires ample water (30 % of the fresh water available worldwide), and its productivity is greatly affected by drought, the most significant environmental factor. Much research has focussed on identifying quantitative trait loci, stress-regulated genes and transcription factors that will contribute towards the development of climate-resilient/tolerant crop plants in general and rice in particular. The transcription factor DREB1A, identified from the model plant Arabidopsis thaliana, has been reported to enhance stress tolerance against drought stress. We developed transgenic rice plants with AtDREB1A in the background of indica rice cultivar Samba Mahsuri through Agrobacterium-mediated transformation. The AtDREB1A gene was stably inherited and expressed in T1 and T2 plants and in subsequent generations, as indicated by the results of PCR, Southern blot and RT-PCR analyses. Expression of AtDREB1A was induced by drought stress in transgenic rice lines, which were highly tolerant to severe water deficit stress in both the vegetative and reproductive stages without affecting their morphological or agronomic traits. The physiological studies revealed that the expression of AtDREB1A was associated with an increased accumulation of the osmotic substance proline, maintenance of chlorophyll, increased relative water content and decreased ion leakage under drought stress. Most of the homozygous lines were highly tolerant to drought stress and showed significantly a higher grain yield and spikelet fertility relative to the nontransgenic control plants under both stressed and unstressed conditions. The improvement in drought stress tolerance in combination with agronomic traits is very essential in high premium indica rice cultivars, such as Samba Mahsuri, so that farmers can benefit in times of seasonal droughts and water scarcity.Electronic supplementary materialThe online version of this article (doi:10.1007/s11248-013-9776-6) contains supplementary material, which is available to authorized users.

Finally, chlorophyll content increased slightly to help plants produce more energy to resist various stresses.…”

The aim of this study was to evaluate the physiological responses of Leymus chinensis (Trin.)Tzvel exposed to long-term salt, salt-alkali, and alkali stress in order to elucidate how L. chinensis can survive under alkaline-sodic soils. L. chinensis (30 days after germination) were stressed with salt [SS; sodium chloride (NaCl)], mixed salt-alkali [MS; molar ratio of NaCl: sodium carbonate (Na 2 CO 3 )=2:1] and alkali salt (AS; Na 2 CO 3 ) at four different levels of sodium (Na + ) concentration (0, 75, 150, and 300 mM) for 60 days. L. chinensis showed 100% survival rate at all treatments except 300 mM SS (33.3%) and AS (18.9%). The growth and physiological parameters of survival plants were measured. As anticipated, growth of L. chinensis was inhibited after stresses, which reflected in the decline of plant height, dry weight and tiller number following the increased Na + concentration. The content of Na + , proline, and soluble sugar in L. chinensis increased with the increasing Na + concentration, suggesting that L. chinensis need to accumulate inorganic and organic solutes for resisting osmotic stress induced by various salt stresses. These processes ensure the water balance that can provide a relative normal physiological environment for L. chinensis. Potassium (K + ) content of L. chinensis kept at a relative lower level than control to ensure the normal physiological processes. Chlorophyll content of stressed plant increased slightly compared to control plants, which can produce more
