Drought episodes are increasing in duration and intensity around the globe because of global climate change. Since plants are sessile organisms, they need plasticity mechanisms to cope with drought periods. These mechanisms vary between annual and perennial plants and may include evolutionary adaptations, as well as rapid molecular changes. This Special Issue is focused on how plants tolerate drought stress regarding anatomical, morphological, physiological and molecular mechanisms in any kind of plant. At the same time, responses can be local or systemic, at the cellular, organ or whole plant levels. Manuscripts should involve new approaches or findings that cause a significant advance in our knowledge of how plants tolerate drought stress.

Abstract: From previous few decades, drought became a serious exceedingly challenge for farming in all over the world. Drought poses significant threat to crop failure and may lead to food shortage. Based on the aim of study, the present research work was performed in pot to enhancing drought tolerance in oil seed crops (camelina & canola) through improving physiochemical, antioxidants and yield related parameters by foliar selenium (Se) application under drought stress in the Cholistan Institute of Desert Studies, The Islamia University of Bahawalpur, Pakistan. Two oil seed crops such as camelina genotypes (Australian camelina and Canadian camelina) and canola genotypes (AARI canola and UAF canola) were grown during the growing season 2016 under control (100% FC) and drought stress (40% FC) conditions. Four different treatments of Se which were selected from screening experiments such as Se priming @ 75μM, foliar Se @ 7.06 μM and foliar Se with priming (7.06 μM & 75μM) along with control were applied at the vegetative stage of both oil seed crops by using randomized complete block design and each replicated thrice. Both crops grown up to maturity and following data of physiochemical, antioxidants and yield components were recorded during this study. Results indicated that the physiochemical parameters (WP, OP, TP, Proline, TSS, TFAA, TPr and TS), total chlorophyll contents and were improved by foliar Se application along with Se seed priming in both oil seed crops in drought stress as well as non-stress conditions as compared to all other treatments, similarly the osmoprotactants (GB, anthocyanin, TPC and flavonoids) and antioxidants (APX, SOD, POD and CAT) were also showed better enhancement in both oil seed crops through application of foliar Se along with seed priming with Se (7.06 μM & 75μM) under normal as well as drought stress conditions as compared to other treatments. Yield components (Number of branches per plant, thousand seed weight, seed yield (t/ha) and biological yield (t/ha)) of both oil seed crops were enhanced by foliar Se with Se seed priming (7.06 μM & 75μM) under stress and non-stress conditions. Foliar Se along with seed priming with Se was helpful in in improving drought tolerance of crops.
Title: Impact of drought in plants: case in the biological metabolism of rice (Oryza sativa)
Author: Xiaojun Zha
Abstract: Drought occupies a major place in the world. it is an environmental catastrophe that gets better with the presence of global warming. Biotic stress is one of the major problems affecting agriculture, especially rice, negatively impacting the bioligic mechanism, leaves, roots and membrane. drought decreases the growth and production of rice in a world where the population continues to grow. the yield becomes low. In this review we see how drought stress affect the rice. In general, we show how abiotic stress affects plants and we provide particular results of the studies on rice.
