Phytohormones regulate accumulation of osmolytes under abiotic stress.

Abstract: Plants face a variety of abiotic stresses, which generate reactive oxygen species (ROS), and ultimately obstruct normal growth and development of plants. To prevent cellular damage caused by oxidative stress, plants accumulate certain compatible solutes known as osmolytes to safeguard the cellular machinery. The most common osmolytes that play crucial role in osmoregulation are proline, glycine-betaine, polyamines, and sugars. These compounds stabilize the osmotic differences between surroundings of cell and the cytosol. Besides, they also protect the plant cells from oxidative stress by inhibiting the production of harmful ROS like hydroxyl ions, superoxide ions, hydrogen peroxide, and other free radicals. The accumulation of osmolytes is further modulated by phytohormones like abscisic acid, brassinosteroids, cytokinins, ethylene, jasmonates, and salicylic acid. It is thus important to understand the mechanisms regulating the phytohormone-mediated accumulation of osmolytes in plants during abiotic stresses. In this review, we have discussed the underlying mechanisms of phytohormone-regulated osmolyte accumulation along with their various functions in plants under stress conditions.

Photosynthetic Response of Plants Under Different Abiotic Stresses: A Review

Abstract: Plants encounter various abiotic stresses due to their sessile nature which include heavy metals, salt, drought, nutrient deficiency, light intensity, pesticide contamination, as well as extreme temperatures. These stresses impose major constraints limiting crop production and food security worldwide. Abiotic stresses primarily reduce the photosynthetic efficiency of plants, due to their negative consequences on chlorophyll biosynthesis, performance of the photosystems, electron transport mechanisms, gas exchange parameters, and many others. A better understanding of the photochemistry of plants under these abiotic stresses can help in the development of pragmatic interventions for managing these stresses. Interestingly, in this review, we provide an overview of insight into different mechanisms affecting the photosynthetic ability of plants in relation to these abiotic factors. The present review describes how different abiotic stresses can pose deleterious impacts on plant photosynthetic machinery including cellular membranes, cell division and cell elongation, biosynthesis of photosynthetic pigments, as well as electron transport chain. It is important to understand the detrimental impacts of various abiotic stresses for better stress management because a comprehensive understanding of plant responses has pragmatic implication for remedies and management.

Creating Satisfied Employees Through Workplace Spirituality: A Study of the Private Insurance Sector in Punjab (India)

Abstract: Spirituality in the workplace is gaining recognition and value among researchers, academicians, and business professionals. The aim of this paper is to examine the impact of spirituality in the workplace on job satisfaction by measuring four dimensions of spirituality in the workplace: meaningful work, sense of community, organizational values, and compassion. The impact of each dimension on job satisfaction is hypothesized. A cross-sectional survey was used to collect data from 100 payroll employees in private insurance companies in Punjab (India). A correlation analysis showed a positive relationship between all the dimensions of spirituality in the workplace and job satisfaction. A regression analysis revealed that although all the dimensions of spirituality in the workplace are important, organizational values and a sense of community are the most important in terms of the job satisfaction level of employees. This work will help insurance companies to better understand the concept of spirituality in the workplace and its importance. Insurance companies can improve their functioning by encouraging employee spirituality in the workplace.
