Agricultural production and dynamic climate changes are internally associated with each other in different facets, including drought, extreme temperatures, salinity, waterlogging, toxic metals/metalloids, nutrient imbalance, etc., which have unpleasant impacts on agricultural productivity. The risk of continuous changing environment has significantly focused the attention of plant scientists, as these changes negatively impact the plant growth and development that ultimately affect crop production and further enhance the challenges of global food insecurity. Owing to the rapid rise of the world's population, there is imperative to bring together knowledge of all fields of plant sciences with groundbreaking efforts in agriculture to maintain plant growth and consequently improve crop yield globally.
To get insight into the plant's adaptive response mechanisms towards environmental changes, researchers should need to in line with their efforts. For example, multi-omics, genome editing, modern breeding techniques, and application of plant growth regulators should be deployed not only to explore candidate genes but also to transfer and produce commercial stress-smart cultivars. Consequently, the quick advancement of studies on the amalgamation between physiological, biochemical, and molecular interventions of plants is important. Information on molecular mechanisms will deliver breeding programs with importance to gaining cultivars tolerant to abiotic stresses with improved productivity. In this scenario, several physiological and modern molecular techniques play a vital role, with a clear demand for modern advances that can speed up the rate of genetic advancement necessary to meet the unprecedented challenge of superior food sustainably. Hence, this special issue will feature the current improvements in physiological and molecular mechanisms to understand and improve the stress (single or combined) acclimation and tolerance mechanisms in the plants to feed the rapidly rising population.
This special issue welcomes submissions of original research, methods, and comprehensive- and mini-review articles related to multiple abiotic stress responses, adaptive and tolerance mechanisms in crop plants.

Nitrogen (N), the building block of plant proteins and enzymes, is an essential macronutrient for plant functions. A field experiment was conducted to investigate the impact of different N application rates (28, 57, 85, 114, 142, 171, and 200 kg ha−1) on the performance of spring wheat (cv. Ujala-2016) during the 2017–2018 and 2018–2019 growing seasons. A control without N application was kept for comparison. Two years mean data showed optimum seed yield (5,461.3 kg ha−1) for N-application at 142 kg ha−1 whereas application of lower and higher rates of N did not result in significant and economically higher seed… More >

Arsenic (As) contaminated food chains have emerged as a serious public concern for humans and animals and are known to affect the cultivation of edible crops throughout the world. Therefore, the present study was designed to investigate the individual as well as the combined effects of exogenous silicon (Si) and sodium nitroprusside (SNP), a nitric oxide (NO) donor, on plant growth, metabolites, and antioxidant defense systems of radish (Raphanus sativus L.) plants under three different concentrations of As stress, i.e., 0.3, 0.5, and 0.7 mM in a pot experiment. The results showed that As stress reduced the growth parameters of… More >

Understanding physiological responses in saline agriculture may facilitate wheat breeding programs. Based on a screening test, the Ningmai-14 (NM-14) and Yangmai-23 (YM-23) wheat cultivars were selected for further experiments to understand the underlying salinity tolerance mechanism. This study investigated the effects of five salinity levels such as Control (CK) = 0 (without NaCl stress), S1 = 0.20%, S2 = 0.25%, S3 = 0.30% and S4 = 0.35% of NaCl concentrations of soil on wheat plants. The results showed that increased salinity concentration reduced the growth and yield of wheat cultivars (NM-14 and YM-23). However, YM-23 (12.7%) yielded more than NM-14… More >
