Sequenced application of glutathione as an antioxidant with an organic biostimulant improves physiological and metabolic adaptation to salinity in wheat Plant Physiol. Biochem. (IF 3.72) Pub Date : 2020-12-02 Hafeez ur Rehman; Hesham F. Alharby; Atif A. Bamagoos; Magdi T. Abdelhamid; Mostafa M. Rady
Globally, salinity threatens the agricultural crops productivity by inhibiting plant growth and development through osmotic stress and ionic cytotoxicity. The polygenic nature of salinity offers several pragmatic shotgun approaches to improve salinity tolerance. The present study investigated the potential of glutathione (GSH; 1 mM) as an antioxidant and moringa leaf extract (MLE; 3%) as an organic

Targeting salt stress coping mechanisms for stress tolerance in Brassica: A research perspective Plant Physiol. Biochem. (IF 3.72) Pub Date : 2020-11-27 Adnan Noor Shah; Mohsin Tanveer; Asad Abbas; Shah Fahad; Mohammad Safdar Baloch; Muhammad Irfan Ahmad; Shah Saud; Youhong Song
Brassica genus comprises numerous cultivated brassica species with various economic importance. Salt stress is an overwhelming problem causing serious losses in Brassica species (e.g. B. napus, B. rapa, B. oleracea, B. juncea) growth and grain yield production by inducing ionic and ROS toxicity. Given that a significant variation exists in salt tolerance level in Brassica genus, Brassica species exhibited

The physiological response of photosynthesis to nitrogen deficiency Plant Physiol. Biochem. (IF 3.72) Pub Date : 2020-11-17 Xiaohuan Mu; Yanling Chen
Nitrogen (N), as a macro-element, plays a vital role in plant growth and development. N deficiency affects plant productivity by decreasing photosynthesis, leaf area and longevity of green leaf. To date, many studies have reported that the relationship between photosynthesis and N supply. Here, we summarized the physiological response of photosynthesis to N deficiency in leaf structure and N allocation
