Sarcocornia quinqueflora; halophytes; models; perennials; photosynthesis; plant adaptation; salinity; suberization
Abstract:
... Senescence of plant tissues is a physiologically synchronized process that enables an evergreen or a perennial plant to retrieve, recycle and remobilize nutrients from elder to younger tissues or upcoming seeds. The succulent perennial halophyte S. quinqueflora utilizes this process to discard excess salt being accumulated in outer tissues of their leafy stems. The exact mechanism for salt sheddin ...

Abstract:
... Greenhouse cultivation forms a relatively closed environment for heat preservation in winter, which inevitably leads to a lack of atmospheric CO₂ concentration ([CO₂]), and thus low [CO₂] level has become a limiting factor for the photosynthesis and growth of greenhouse vegetables. Most cucurbits and solanaceous vegetables are sensitive to low temperature, but it is difficult to keep the optimum r ...

Abstract:
... Chickpea is a cheap source of protein and micronutrients to the poor and vegetarian population living in south-Asia and sub-Saharan Africa. Due to changes in climatic conditions and cropping systems, the crop is being exposed to severe drought and heat stress during its reproductive period, which leads to significant yield losses and fluctuations in grain nutrient accumulation. The study was condu ...

Abstract:
... Reactive oxygen species (ROS) produced due to drought stress can lead to the oxidation of methionine in plant cells; this can then be reduced by methionine sulfoxide reductases (MSRs). To the best of our knowledge, no information has been reported to date on the function and substrates of wheat cytoplasmic TaMSRB5.2, which is induced by drought mainly both in the leaves and roots. In the present s ...
