“…Plants normally cope with salt stress by accumulating compatible solutes including proline and sugars (Pattanagul and Thitisaksakul, 2008), which help in the osmotic adjustments. Proline is a potential osmolyte for countering the stress and providing resistance (Arshi et al, 2002, Arshi et al, 2004); it acts as a source of nitrogen under normal conditions (Tie et al, 2014). The accumulation of proline increased linearly under salt stress concentrations in all genotypes (Fig.…”

Salt stress, which is dominant among environmental stresses, poses challenges to global agriculture. We studied the role of exogenous application of sodium chloride (NaCl) in three arid and three semi-arid genotypes of mungbean [ Vigna radiata (L.) Wilczek] by examining some physiological and biochemical stress indicators. Ten-day old seedlings were subjected to salt stress (00–250 mM) by split application along with the half strength Hoagland’s medium. The salt stress caused a decline in the fresh weight, dry weight, relative water content, photosynthetic pigments (chlorophyll and carotenoids) and glutathione content of the seedlings. On the other hand, it increased the electrolyte leakage, lipoxygenase activity, and the proline, protein and total soluble sugar contents. Osmolyte accumulation was relatively higher in the arid genotypes revealing that they are more tolerant to NaCl stress. The physiological and biochemical screening provides a basic platform for selecting the stress-tolerant genotypes in the absence of suitable salt-tolerance markers in mungbean.

“…Compatible solutes like proline and betaine have been reported to help maintain osmotic balance in plant cells (Arshi et al 2002;Hasegawa et al 2000). Proline can also scavenge ROS (Hong et al 2000;Okuma et al 2004) while adjusting osmotic pressure, stabilizing complex II electron transport chain (Hamilton and Heckathorn 2001), membranes and proteins (Hare and Cress 1997) and potentially acting as an active metabolic regulator.…”

Improving salinity resilience inSwertia chirayitaclonal line withLactobacillus plantarum

Plants defense responses to abiotic stresses, including salinity stress, involve stimulation of defense related pathways such as biosynthesis of secondary metabolites and induction of endogenous antioxidant enzyme responses. In the present study, a single seed origin clonal line of Swertia chirayita inoculated with Lactobacillus plantarum (LP) was grown under different salinity levels. Control had no LP inoculation. S. chirayita inoculated with LP showed higher accumulation of proline, low proline dehydrogenase activity, up-regulation of pentose phosphate pathway, down-regulation of succinate dehydrogenase activity (Krebs cycle) and low total phenolic content with increased salt concentrations. In comparison, S. chirayita without LP adopted a different biochemical mechanism to counter salt stress (NaCl) by up-regulating both pentose phosphate pathway and Krebs cycle along with stimulation of phenolic biosynthesis. Guaiacol peroxidase (GPX) activity increased with and without LP treatment in response to increasing concentrations of salt. These results indicate that S. chirayita inoculated with LP exhibits a greater salinity stress tolerance than S. chirayita without LP by adopting a more energy efficient defense responses and potentially efficiently partitioning carbon flux between primary and secondary metabolism to counter salt induced oxidative stress.

“…Sodium Na is an essential element which plays a vital role along with K and Cl for normal distribution of fluids in both extra and intra-cellular cells of the body while serving as an electrolyte. Decrease in biomass, photosynthetic rate and protein content was observed in some medicinal plants with increase of Na concentration 69 . From the results obtained in this work, Na/K ratio was found low enough in all medicinal plants analyzed indicating adequate and balanced quantities of these essential elements.…”

INTRODUCTION Among the protected areas, national parks and nature reserves cover about 12 of the earth s surface, which acts as a backbone for biodiversity conservation. National parks provide a primary source of safe ecosystem services in addition to their recreational role, essential for healthy well-being. These national parks, also, serve as a diversified habitat for many valuable medicinal plants. Many researchers focused on the study of important medicinal plants present in National parks of Pakistan and document their
