“…Greenhouse and field studies showed that drought stress led to significant reduction in seed yield (24~50%) from distinct locations and time (Frederick et al, 2001;Sadeghipour et al, 2012). Soybeans are more flexible than corn in adapting to periods of moisture stress.…”

“…A QTL was identified for relative water content on chromosome 7 in maize . Virginia et al (2012) identified 3 QTLs for Abdi et al (2013) identified 6 QTLs under well watered conditions and 2 QTLs under drought stress conditions for relative water content in sunflower. Tripathy et al (2000) identified 9 putative QTLs for CMS located on chromosome 1, 3, 7, 8, 9, 11 and 12 in rice.…”

Drought is one of the major abiotic stresses affecting crop plants worldwide including cotton. QTLs were identified to assess the genetic control of relative leaf water contents, excised leaf water loss, cell membrane stability, stomatal size and frequency under drought. An F 2 population was developed by an intraspecific crossing between drought tolerant genotype (FH-207) and drought susceptible genotype (FH-901) of Gossypium hirsutum. A total of 2365 EST-SSR primers were screened to identify polymorphism between two contrasting parents. One hundred primers showing polymorphic amplification were used to score F 2 population for QTL mapping. Two QTLs for relative leaf water contents on chromosome A5, one for excised leaf water loss on chromosome A7, one for cell membrane stability on chromosome A1, one for stomatal size on chromosome A6 and one for stomatal frequency on chromosome A13 were identified. These QTLs would be helpful to develop drought tolerant cotton cultivar.

“…After 14 days of salt treatment, plant height, root length, and fresh weight were measured with a Vernier caliper and scale. The relative water content (RWC) of the leaves, stem, and root was calculated according to protocols described by Virginia et al (2012). Total chlorophyll contents were evaluated with a method previously described (Gao and Peng, 2006).…”

Melatonin, widely found in various plants as a new antioxidant, could protect plants from various biotic and/or abiotic stresses, including salt stress. MzASMT 1 (KJ123721), a gene from Malus zumi Mats, is a key enzyme required for melatonin synthesis. However, whether the overexpression of MzASMT 1 could regulate the synthesis of melatonin and improve the salt tolerance in tobacco remains unknown. In this study, the overexpression of MzASMT 1 in tobacco increased the melatonin content, and the transgenic lines owned higher salt tolerance capacity. The transgenic lines overexpressing MzASMT 1 exhibited lower degree of leaf wilting; much more fresh weight; higher plant height; longer root; higher relative water content (RWC) of leaves, stem, and root; and higher chlorophyll content and Fv/Fm, which makes transgenic lines better adapt to salt stress. The transgenic lines also had higher accumulation of proline, lower accumulation of malondialdehyde (MDA), and improved antioxidant systems, which protected plants from cell damage and oxidative stress due to excess reactive oxygen species (ROS) accumulation under salt treatment. The transcription of salt response genes was much more highly activated in transgenic lines than in wild type under salt stress. The above results contributed to the understanding of functions for MzASMT 1 in tobacco under salt stress and provided a new choice for the application of MzASMT 1 in improving plant salt tolerance.
