Article Abstract
Drought is a major environmental stress that limits growth and productivity in agricultural ecosystems limiting crop yield worldwide. Breeding crops for enhanced drought tolerance is a priority to preserve food security on the increasing world population. Recent work in Arabidopsis has shown that vascular brassinosteroid receptor BRL3 (Brassinosteroid insensitive like-3) transcriptionally controls the production of osmoprotectant metabolites that confer drought resistance without penalizing growth, offering new and exciting possibilities for biotechnological improvement of drought-resistant crops. In cereals, understanding transcriptional responses to drought is an essential step for the production of gene-edited drought-resistant cereals. In this chapter, we present a method to analyze the transcriptional responses to drought in Sorghum bicolor (L.) Moench, our cereal of choice. Among the genes we tested, we found that drought marker gene SbDHN1 has a 1000-fold increase only after 1 day of drought, bringing possibilities for the development of molecular sensors for testing drought. Overall, this analysis is useful to set up conditions of high-throughput transcriptomic analysis of drought stressed plants before drought phenotype is observed.

Plant water potential is one of the most frequently measured variables of plant water status. Stem water potential, often approximated by wrapping the leaves, is assumed to be more stable and a better measure of drought stress than leaf water potential. In wheat (Triticum aestivum L.

The soil in reclaimed shale gas sites is compacted and suffers from issues like poor drainage, drought conditions, and nutrient deficiency, posing challenges for agricultural production. In this study, rare earth tailings were incorporated into biochar at different mass ratios (rare earth tailings: biochar = 1:1, 1:2, 1:3, 1:4). Subsequently, a series of rare earth tailings-doped biochar materials (REE-BC) were prepared by calcination at 700°C.

The size and composition of local species pools are, in part, determined by past dispersal events. Predicting how communities respond to future disturbances, such as fluctuating environmental conditions, requires knowledge of such histories. We assessed the influence of a historical dispersal event on community assembly by simulating various scales of dispersal for 240 serpentine annual plant communities that experienced a large shift from drought to high rainfall conditions over three years.

Drought stress is the most vulnerable abiotic factor affecting plant growth and yield. The use of silicic acid as seed priming treatment is emerging as an effective approach to regulate maize plants susceptibility to water stress. The study was formulated for investigating the effect of silicic acid seed priming treatment in modulating the oxidative defense and key physio-biochemical attributes of maize plants under drought stress conditions.

Water deficit stress causes devastating loss of crop yield worldwide. Improving crop drought resistance has become an urgent issue. Here we report that a group of abscisic acid (ABA)/drought stress-induced monocot-specific, intrinsically disordered, and highly proline-rich proteins, REPETITIVE PROLINE-RICH PROTEINS (RePRPs), play pivotal roles in drought resistance in rice seedlings.
