Separation of proteins based on the physicochemical properties with different molecular weight and isoelectric points would be more accurate. In the current research, the 45-day-old seedlings were treated with 0 (control) and 12 dS m(-1) of sodium chloride in the hydroponic system. After 15 days of salt exposure, the total protein of the fresh leaves and roots was extracted and analyzed using t...

Effect of various NaCl treatments (0, 50, 100, 200, and 300 mM) at different growth and development stages (tillering, boot swellen, flowering and anthesis) in two wheat cultivars (Ghods: salt – sensitive, Boolani: salt – resistant) on SDS-PAGE electrophoretic pattern of leaf proteins was studied under greenhouse conditions. Generally, in response to salinity treatments, the decrease in protein...

Seasonal changes in photosynthetic capacity, leaf nitrogen (N) content and N partitioning were studied from before leaf maturation (spring) until death (autumn) in high- and low-light-exposed leaves of a deciduous shrub, Lindera umbellata var. membranacea (Maxim.) Momiyama growing in a natural forest in northeast Japan. In spring, light-saturated photosynthetic rate (Pmax) was low despite high ...

The relationship between spatial density and size of plants is an important topic in plant ecology. The self-thinning rule suggests a -3/2 power between average biomass and density or a -1/2 power between stand yield and density. However, the self-thinning rule based on total leaf area per plant and density of plants has been neglected presumably because of the lack of a method that can accurat...

High-performance mass spectrometry (MS)-based proteomics enabled the construction of a detailed proteome atlas for Populus, a woody perennial plant model organism. Optimization of experimental procedures and implementation of current state-of-the-art instrumentation afforded the most detailed look into the predicted proteome space of Populus, offering varying proteome perspectives: (1) network-...

chickpea (cicer arietinum l.) is mainly cultivated in arid and semi-arid agricultural systems. drought stress is a major factor delimiting maximum yield. this research evaluated the effects of drought stress treatments on expression of cu/znsod as a gene involving in drought tolerance by real time pcr technique. to find the probable relationship between the molecular and physiological effects o...

Premature leaf senescence occurs in the ultimate phase of the plant, and it occurs through a complex series of actions regulated by stress, hormones and genes. In this study, a proteomic analysis was performed to analyze the factors that could induce premature leaf senescence in two cotton cultivars. We successfully identified 443 differential abundant proteins (DAPs) from 7388 high-confidence ...
