Summary: The Green Revolution's unprecedented wheat yield increases were achieved through the introduction of Rht-B1b and Rht-D1b semi-dwarfing alleles, encoding N-terminal truncated proteins that cause dwarfism without affecting dormancy, through translational reinitiation. The study also demonstrated the degradation process of wild-type RHT-1 proteins in response to gibberellin in wheat organs, providing insights into the molecular mechanisms underlying the agronomic traits.

Summary: Chickpea production is susceptible to drought stress. A genetic region called 'QTL-hotspot' has been identified to control chickpea growth and improve crop production under drought. A non-synonymous substitution in the CaTIFY4b transcription factor has been found to regulate seed weight and organ size in chickpea, and ectopic expression of CaTIFY4b in a different plant species enhances root growth under water deficit. Gene expression analysis suggests that CaTIFY4b may regulate organ size under water deficit by modulating the expression of a transcriptional co-activator called GIF1. These findings provide new insights into the physiological and molecular mechanisms of chickpea growth and production under specific drought conditions.

Summary: Drought has a significant impact on crop growth, and understanding the short-term and long-term responses of crops to drought is crucial. Field data analysis showed that different water supply treatments strongly influenced leaf and canopy gas exchange, as well as cumulative growth in winter wheat and maize. The long-term morphological responses of winter wheat played a larger role in regulating transpiration and assimilation rates, while maize exhibited physiological advantages and morphological adjustments under drought conditions. Improved modeling of gas exchange and crop growth should consider dynamic changes in leaf area and stomatal regulation.

Summary: Intercropping is a sustainable practice for enhancing crop productivity and water use efficiency under rainfed conditions. This study aimed to investigate the contribution of different crop rows and nitrogen application on the physiological, yield, and related traits of wheat/maize relay-strip intercropping. Results showed that intercropping significantly improved land use efficiency and grain yield of both crops, especially with nitrogen application.

Summary: Efficient utilization of limited water resources and improving agricultural water use efficiency are major challenges for global food security. This study used carbon and water flux data from multiple site-years to analyze the variability in canopy-scale transpiration and ecosystem-scale evapotranspiration across major crops, including maize, winter wheat, and soybean. The results revealed seasonal patterns and differences among the crops in terms of transpiration and evapotranspiration, as well as water use efficiencies.

Summary: Breeding new high-yielding and stress-tolerant wheat varieties requires the introduction of new genetic diversity, which can be obtained from genebanks and the wild relatives of crops. Pre-breeding, by identifying genetic regions associated with desirable traits, contributes novel beneficial diversity and aids in increasing wheat productivity.

Summary: This study aimed to calibrate the field capacity (FC) value in the bucket-type model WOFOST in order to best simulate the water balance predicted by the Richards equation-based model SWAP, considered as a benchmark. The calibrated FC value depended on various factors such as targets, soil type, climate, and crop drought sensitivity.

Summary: The study found genetic variation in the limiting transpiration VPD trait exists within cotton genotypes in the Australian breeding programme, with five genotypes identified as expressing the TRLim VPD trait. However, while the yield performance of the TRLim genotype was improved in some high VPD environments, it is unlikely to out-perform a genotype with a lower yield potential.

Summary: Adequate management practices, including N supply, plant density, row spacing, and soil cover, have been proven effective in increasing grain yields and/or yield stability of rainfed crops. This review examines the impact of these practices on water-related determinants of grain yield, specifically crop evapotranspiration (ET) and water use efficiency for grain production (WUEG,ET,s). The study reveals conflicting results regarding the impact of management on ET and highlights the complexity of the ET response to environmental factors. The influence of management practices on WUEG,ET,s is analyzed in terms of three main processes: transpiration ratio (T/ET), transpiration efficiency for biomass production (TEB), and harvest index.

Summary: Inaccurate crop coefficients lead to inefficient use of water resources. This study evaluated the method of deriving crop coefficients developed by Allen and Pereira (2009) for various irrigated fruit tree crops in South Africa. The study adjusted the stoma-tal sensitivity function in the model by replacing the ratio of the leaf resistance to the standard leaf resistance with a resistance parameter specific to each crop. The derived crop coefficients were standardized and tabulated for transferability between sites, but more crop-specific information is needed to improve accuracy.

Summary: Improving canopy photosynthetic light use efficiency and energy conversion efficiency is crucial for increasing crop yield potential. However, the diurnal and seasonal variations of canopy light use efficiency and energy conversion efficiency have been largely unknown. This study quantified the dynamic changes in these parameters and found significant variations throughout the day and growing season. The results highlight the opportunity to improve canopy photosynthesis for greater wheat biomass and yield potential.

Summary: The selection for early shoot vigour in wheat is associated with increased root hair length and changes to cell size in roots and shoots. Six cycles of recurrent selection for early shoot vigour in wheat resulted in significant increases in leaf width and shoot biomass. Increased shoot vigour was associated with greater root biomass, larger rhizosheath size, and longer root hairs.

Summary: Global warming and unreliable rainfall pose threats to wheat yields, but deep sowing and improved genotypes can increase wheat production. Research shows that wheat genotypes with improved genes can adapt to climate change by deep sowing, and this improvement has positive effects on increasing yields in both Australia and other dryland wheat production regions globally.

Summary: The study found that sensing neighboring plants through the Red to Far-Red light ratio (R:FR) can limit yield potential in wheat. The effects of increased R:FR within the canopy were studied in dense wheat mini canopies grown in controlled environments. The response to high R:FR depended on the developmental stage and cultivar, showing positive effects if applied after stem elongation but negative or null effects if applied before. Combining high R:FR with elevated CO2 or CO2 alone also had cultivar-dependent effects. These findings suggest that R:FR plays a significant role in controlling yield potential in wheat.

Summary: The size of the embryo is genetically associated with root structure, which plays an important role in increasing crop yield in droughted field environments. The growth and development of seedling roots are closely related to embryo size, rather than plant height or development. This study is the first to report on the genetic relationship between seedling root architecture and embryo size, providing a potential approach for selecting seminal root size to access deep-soil moisture in droughted environments.

Summary: Long coleoptile (LC) - wheat genotypes, sown deeper than current practice, enable earlier deep sowing into subsurface soil moisture. The LC genotype shows promise to broaden sowing windows and remove reliance on the shifting seasonal break for crop establishment. Investigation is needed to identify suitable environments for potential establishment benefits in the highly variable soils of the southern Australian wheatbelt.

Summary: Drought is a pressing issue worldwide, and selecting wheat genotypes adapted to changing climatic conditions is crucial. This study evaluated 156 bread wheat genotypes, including landraces and modern varieties, under different drought treatments. The results showed that landraces had higher yield stability and protein content under drought stress, suggesting their potential for developing drought-tolerant modern wheat varieties. Effective utilization of landraces in breeding programs is important for developing climate-resilient wheat varieties.
