Mungbean is an important pulse crop extensively cultivated in Southeast Asia for supply of easily digestible protein. Salinity severely limits the growth and productivity of mungbean, and weeding poses nutritional and disease constraints to mungbean cultivation. To pyramid both salt tolerance and protection against herbicide in mungbean, the AtNHX1 encoding tonoplast Na+/H+ antiporter from Arab...
Are plant cells just yeast cells with chloroplasts? Should plant cell biologists who don’t work on chloroplasts just switch to yeast to help solve the basic questions that are common to all eukaryotes? The recent completion of the sequencing of the entire yeast (Saccharomyces cerevisiae) genome and the availability of hundreds of well-characterized mutants certainly make this a tempting proposi...
One of the major abiotic stresses affecting agriculture is soil salinity, which reduces crop yield and, consequently, revenue for farmers. Although tomato is an important agricultural species, elite varieties are poor at withstanding salinity stress. Thus, a feasible way of improving yield under conditions of salinity stress is to breed for improved salt tolerance. In this study, we analysed th...
Oilseed mustard, Brassica juncea, exhibits high levels of genetic variability for salinity tolerance. To obtain the global view of transcriptome and investigate the molecular basis of salinity tolerance in a salt-tolerant variety CS52 of B. juncea, we performed transcriptome sequencing of control and salt-stressed seedlings. De novo assembly of 184 million high-quality paired-end reads yielded ...
For plants growing in highly saline environments, accumulation of sodium in the cell cytoplasm leads to disruption of metabolic processes and reduced growth. Maintaining low levels of cytoplasmic sodium requires the coordinate regulation of transport proteins on numerous cellular membranes. Our previous studies have linked components of the Salt-Overly-Sensitive pathway (SOS1-3) to salt toleran...
Arabidopsis pumila is an ephemeral plant, and a close relative of the model plant Arabidopsis thaliana, but it possesses higher photosynthetic efficiency, higher propagation rate, and higher salinity tolerance compared to those A. thaliana, thus providing a candidate plant system for gene mining for environmental adaption and salt tolerance. However, A. pumila is an under-explored resource for ...
Transport across insect epithelia is thought to depend on the activity of a vacuolar-type proton ATPase (V-ATPase) that energizes ion transport through a secondary proton/cation exchanger. Although several of the subunits of the V-ATPase have been cloned, the molecular identity of the exchanger has not been elucidated. Here, we present the identification of sodium/proton exchanger isoform 3 (NH...
چغندرقند (beta vulgaris l.) گیاهی است که به شوری آب و خاک مقاوم بوده ولی در مرحله جوانه زنی گیاهی گلیکوفیت و در سایر مراحل رشد گیاهی هالوفیت به شمار می رود. به منظور بررسی تحمل به تنش شوری پنج رقم (7233-p.29 × ms2 ، رسول، ic1، 8001- p.3 و 8001-p.7 × ms2 ) چغندرقند در چهار سطح تنش (0، 50، 150 و 250 میلی مولار) با نمک کلرید سدیم آزمایشات مختلفی در مراحل جوانه زنی و کشت بافت اجرا گردید. در آزمون ج...
even when ECe is 3.0 dS m 1 (Table 1), which in terms of osmotic potential is less than –0.117 MPa (osmotic One-fifth of irrigated agriculture is adversely affected by soil salinpotential 0.39 ECe). At these salinity levels, the ity. Hence, developing salt-tolerant crops is essential for sustaining predominant cause of crop susceptibility appears to be food production. Progress in breeding for ...
