Salinity is an important abiotic stress that limits rhizobia-legume symbiosis, affecting plant growth, thus reducing crop productivity. Our aims were to evaluate the tolerance to salinity of native chickpea rhizobia as well as to investigate the expression of chaperone genes groEL, dnaKJ and clpB in both tolerant and sensitive isolates. One hundred and six native chickpea mesorhizobia were scre...

We introduced a multistep screening method to identify the genes in plants using microarrays and ribonucleic acid (RNA)-seq transcriptome data. Our method describes the process for identifying genes using the salt-tolerance response pathways of the potato (Solanum tuberosum) plant. Gene expression was analyzed using microarrays and RNA-seq experiments that examined three potato lines (high, int...

When young plants o f barley and wheat grown in hydroponic culture were subjected to salt stress, their freezing tolerance increased with increasing severity o f salt stress. Detached leaves from salt-stressed plants also exhibited an increased ability to supercool. Avoidance o f ice for­ mation permitted leaf survival at subzero temperatures which were no longer tolerated when ice nucleation r...

to improve bread wheat salt tolerance, new genetic sources of salt tolerance are indispensable, and this requires a screening of wheat germplasm. in order to evaluate bread wheat germplasm, 34 accessions including; hexaploid wheats (aabbdd), tetraploid (aabb) and wild relative diploids (dd and aa genome) collected from different regions of iran were evaluated under normal vs. salinity stress (n...

Background The C-repeat-binding factors/DRE-binding factors (CBF/DREBs) comprise a key transcription factor family involved in plant stress tolerance. Yet, there is limited information about switchgrass DREB genes and their functional roles. Results In this study, four cold-inducible PvDREB1s were identified from switchgrass (Panicum virgatum), among which PvDREB1C was the one responded to co...

The Arabidopsis gene AtNHX1 encodes a vacuolar membrane-bound sodium/proton (Na(+)/H(+)) antiporter that transports Na(+) into the vacuole and exports H(+) into the cytoplasm. The Arabidopsis gene SOS1 encodes a plasma membrane-bound Na(+)/H(+) antiporter that exports Na(+) to the extracellular space and imports H(+) into the plant cell. Plants rely on these enzymes either to keep Na(+) out of ...

Soybean is an important economic crop that is continually threatened by abiotic stresses, especially salt stress. Wild soybean is an important germplasm resource for the breeding of cultivated soybean. The root system plays a very important role in plant salt tolerance. To explore the salt tolerance-related mechanisms among Soja, we have demonstrated the seedling roots' growth and metabolomics ...
