Researchers analyzed expression of candidate genes at Lr46/Yr29 locus in wheat resistant to leaf rust caused by Pt. Identified gene Lr46-Glu2 may play role in resistance response. This study provides insight for developing disease-resistant wheat varieties.
146 wheat genotypes were evaluated for drought tolerance, resulting in the identification of 9 tolerant genotypes. Genome-wide association study identified markers and candidate genes for drought tolerance, aiding future breeding programs.
Scientists used CRISPR/Cas9 to edit plant genes for traits like yield and stress tolerance. Multiplexing is important for efficient gene editing. Focus on enhancing local landraces for sustainable crop improvement.
Researchers identified a genetic trait (QPm.NOBAL-3A) in Nordic and Baltic spring wheat that provides strong resistance against powdery mildew. This finding can aid in sustainable crop protection and breeding efforts to develop wheat varieties with durable resistance against the disease. Markers have also been developed for use in breeding programs.
Scientists studied phytochrome-interacting factors in wheat, identifying 18 genes categorized into four groups. Two active genes, TaPIF2-1B and TaPIF4-5B, were found to impact plant development and stress responses, providing insight into PIF-mediated stress responses in wheat.
The study discovered and mapped two new cold resistance genes in wheat, which can help improve wheat yield in low temperature conditions. The genes control cold resistance and their identification lays the foundation for further research and cloning.
Scientists identified two genes involved in the expression regulation of low-molecular-weight glutenin subunits (LMW-GSs) in wheat. Understanding this could lead to the development of wheat as a bioreactor for producing beneficial substances.
Climate change impacts wheat yield through drought and nutrient imbalances. Research on 200 wheat genotypes identified genetic variations in response to drought and nitrogen stress, revealing QTLs linked to these factors. Contrasting haplotypes on chromosomes 1B and 5A affect nitrogen uptake and use efficiency, and a candidate gene for cold shock protein was implicated. These findings could aid the development of diagnostic markers for drought tolerance and nitrogen use efficiency in wheat.
This study identified 93 MAPK cascade genes in foxtail millet, divided into subgroups, and revealed their response to hormones and stress. Important for understanding plant growth and stress response.
This review discusses how genome editing tools, specifically CRISPR/Cas9, can improve wheat quality and productivity by targeting specific loci in the plant genome.
