Drought is an important abiotic stress factor limiting crop productivity worldwide and its impact increasing with climate change. Regardless of the plant growth period, drought has a deadly yield-reducing effect on at every stage development. As many environmental stressors, drought-exposed plants trigger series molecular, biochemical, physiological responses to overcome stress. Currently, researchers are trying determine complex functioning response in different approaches. Plants more sensitive during certain critical stages like germination, seedling formation, flowering, fertilization, grain formation periods. have high success reducing effects vegetative development periods activity tolerance mechanisms. On other hand, generative period can cause irreversible losses yield. This review focuses progression mechanisms involved field crops stages.

Some cereal crops can withstand harsh growing conditions, and, hence, be considered an important line of defense against food shortage under climate change. Sorghum ( bicolor (L.) Monech) is the main crop for millions people, especially in sub-Saharan Africa and South Asia. This performs well input constraints (e.g., limited water) exhibits high resilience to adverse conditions temperature, drought, waterlogging), making it a star combating hunger However, sorghum other similar are not tolerant absolute terms. Climate change could push these beyond limits they tolerate, jeopardizing security people around world. In this research, we analyzed current status production, trends, factors controlling yield using empirical approaches. Especially Africa, cultivated widely unfavorable sub-optimal levels. Our findings raise multiple concerns as highlight opportunities sustainability cultivation future with seems increase persistently despite global warming due improved inputs approach, offering hope that adaptation approaches fruitful, Africa. A combination interventions including adequate use fertilizers technology adoption cultivars), efficient management (e.g. irrigation), better agronomic practices, key boosting ensuring warmer climate.

Abstract Agricultural sufficient productivity is of paramount importance for ensuring food security and conserving soil health to support the world's agronomy. Climatic abruptions have been emerging as one most nerve‐pressing issues sustainment planet Earth in twenty‐first century. Among various environmental constraints, drought stress stands out a potent factor restricting crop growth productivity. It triggers myriad intricate responses plants combat underlying stress‐mediated adversities. Gaining comprehensive understanding key physiological molecular mechanisms that enable withstand crucial developing effective strategies enhance resilience. Ethylene, gaseous plant hormone, influences adaptive measures adopted by subjected regulating signal transduction‐associated responses. The present review article provides an in‐depth critical roles ethylene enhancing plants' ability restrain severity stress. also highlights significance signaling components survival tolerance. Additionally, we illustrated additive antagonistic interactions with other regulators, which instigate tolerance Conclusively, this emphasizes complex networks involved ethylene‐mediated tolerance, providing valuable insights future research uncovering novel studies field biology.

Increasing demand for food and environmental stressors are some of the most challenging problems that human societies face today these have encouraged new studies to examine drought impacts on production. Seeking discuss important issues in South African context, this study analyzed security one country's largest commercial agricultural land (Free State Province). Earth observation crop data were acquired from Application Extracting Exploring Analysis Ready Samples (AppEEARS) GrainSA databases, respectively years 2011/2012–2020/2021 over Free Province. Two crops namely, maize sorghum obtained database accordingly quantify two crops. The result reveals 2015 2018 affected by extreme events (<10%) where majority area was impacted. Years 2011, 2016, 2018, 2019 severely (>30%) impacted sector area. Findings further revealed production observed lowest recorded year 2014 with about 223,600 119,050 tons, respectively. More so, results showed 2019, 23,600, 24,640, 24,150 order during period study. confirm productions other years. This development might area, outcome will enable decision-making bodies enhance improved strategy vulnerable areas.

Millets are small-grained nutritious minor cereal crops that resistant to different abiotic stresses resulting from climate change. Despite their many benefits, millets have received limited attention in agricultural research, policies, and markets. Considering the importance of millets, recently government tropical countries including India Bangladesh give more emphasis cultivation improvement. Moreover, Food Agricultural Organization United Nations (FAO) declared 2023 be "International Years Millets". In these connections, a details updated review pros cons its improvement this region warrant due attention. The therefore, examines potential main barriers adoption promotion millet region. These include research development efforts, inadequate infrastructure inputs, weak market linkages demand, insufficient awareness knowledge about millets' nutritional environmental benefits. This also highlighted prospects strategies for scaling up especially Bangladesh. increasing public private investment extension services, strengthening farmers' organizations linkages, promoting millet-based value chains products, integrating into nation's food policy. concludes might support equitable sustainable growth, which would contribute global security could help attain goals (SDGs). However, achieving will require concerted efforts multiple stakeholders, farmers, researchers policymakers. emphasizes need multi-disciplinary multi-stakeholder approach prioritizes innovation, inclusiveness, sustainability. Lastly, highlights investigation socioeconomic, environmental, effects production with special on order evidence-based policies practices.

Drought stress severely threatens the yield of cereal crops. Therefore, understanding molecular mechanism drought response plants is crucial for developing drought-tolerant cultivars. NAC transcription factors (TFs) play important roles in abiotic plants, but functions TFs sorghum are largely unknown. Here, we characterized a gene, SbNAC9, and found that SbNAC9 can be highly induced by polyethylene glycol (PEG)-simulated dehydration treatments. We therefore investigated function response. Sorghum seedlings overexpressing showed enhanced drought-stress tolerance with higher chlorophyll content photochemical efficiency PSII, stronger root systems, reactive oxygen species (ROS) scavenging capability than wild-type. In contrast, silenced virus-induced gene silencing (VIGS) weakened tolerance. Furthermore, directly activate putative peroxidase SbC5YQ75 ABA biosynthesis SbNCED3. Silencing SbNCED3 led to compromised reduced seedlings, respectively. our findings revealed role may shed light on genetic improvement other crop under conditions.

With global warming, drought stress is becoming increasingly severe, causing serious impacts on crop yield and quality. In order to survive under adverse conditions such as stress, plants have evolved a certain mechanism cope. The tolerance mainly improved through the synergistic effect of regulatory pathways, transcription factors, phytohormone, stomatal movement, osmotic substances, sRNA, antioxidant systems. This study summarizes research progress plant resistance, in provide reference for improving resistance cultivating drought-resistant varieties genetic engineering technology.
