to understand the effects of salinity stress on four different growth stages of sorghum, a greenhouse experiment with 10 treatments, considering all possible combinations of salinity stress and salt- free periods was carried out. the four growth stages for stress application included: emergence until growing point differentiation, growing point differentiation until half bloom, half bloom until...

Glycinebetaine (hereafter referred to as betaine) is a compatible solute that accumulates in certain plants and microorganisms in response to various types of stress. We demonstrated previously that when the cyanobacterium Synechococcus sp. PCC 7942 (hereafter Synechococcus) is transformed with the codA gene for choline oxidase, it can synthesize betaine from exogenously supplied choline, exhib...

salinity and drought are two major abiotic stresses that affect rice (oryza sativa l.) production in worldwide. salt and drought tolerance and high seedling vigor of rice is one of the important traits in the establishment of seedling in direct planting system and saline and drought environments. in this research, the mapping population of f2:4 families derived from the cross between local vari...

HIGHLIGHTS Metabolites and transcripts related to plant physiology in salt stress conditions, especially to the recovery process were disclosed in peanut. Peanut (Arachis hypogaea L.) is considered as a moderately salt-sensitive species and thus soil salinity can be a limiting factor for peanut cultivation. To gain insights into peanut plant physiology in response to salt stress and alleviation...

Salinity stress is a major abiotic factor that affects crop output, and as a pioneer crop in saline and alkaline land, salt tolerance study of cotton is particularly important. In our experiment, four salt-tolerance varieties with different salt tolerance indexes including CRI35 (65.04%), Kanghuanwei164 (56.19%), Zhong9807 (55.20%) and CRI44 (50.50%), as well as four salt-sensitive cotton varie...

Vibrio cholerae, which is a serious human intestinal pathogen, often resides and thrives in estuaries but requires major self-regulation to overcome intestinal hyperosmotic stress or high salt stress in water and food. In the present study, we selected multiple O1 and O139 group V. cholerae strains that were isolated from different regions and during different years to study their salt toleranc...

water and soil salinity are two of the most important limiting factors in crop production. phosphatase enzymes are widely found in plants. phosphatase enzymes are responsible for de-phosphorylation of organic phosphate and altering it to mineral phosphate. germination experiments were conducted using two bread wheat cultivars, namely, iniya66 and ghods along with application of different nacl p...

To understand the role of small GTPases in response to abiotic stress, we isolated a gene encoding a small GTPase, designated MfARL1, from a subtracted cDNA library in Medicago falcata, a native legume species in semi-arid grassland in northern China. The function of MfARL1 in response to salt stress was studied by expressing MfARL1 in Arabidopsis. Wild-type (WT) and transgenic plants constitut...
