Summary: Research on the potential of photosynthesis to improve crop yields has led to the identification of breeding targets. The enzyme Rubisco, responsible for CO2 fixation, is inefficient and often limits carbon assimilation in wheat. Two bread wheat lines with similar genetic backgrounds but contrasting Rubisco activity were chosen for detailed study. Phenotypic analysis of photosynthetic traits in these lines showed no difference in Rubisco activity between in vivo and in vitro methods. Additionally, there was no correlation between photosynthetic traits measured in field-grown plants using high-throughput phenotyping. These findings highlight the need to consider the complex interplay between traits and the dynamic environment in breeding strategies for wheat yield improvement.

Summary: This study investigated the effects of different sowing densities and nitrogen topdressing at the jointing stage on dry matter, quality, and yield under wheat hole sowing. It was found that high sowing density and nitrogen topdressing can improve the dry matter quality of wheat spikes at the maturing stage. The sowing density has significant effects on protein content, starch content, and sedimentation value. The recommended combination is a sowing density of 225 kg/ha and a nitrogen topdressing of 120-180 kg/ha.

Summary: The growth and productivity of wheat are influenced by factors such as sowing time, tillage system, and nutrient application. This study found that sowing dates and boron application had beneficial effects on wheat growth and productivity. Wheat sown on November 15th showed the highest plant height, chlorophyll contents, grains per spike, and grains' boron content. Similarly, the application of boron under late-sown conditions improved wheat yield parameters. Overall, applying 2 kg/ha of boron can enhance wheat grain yield and productivity under late-sown conditions.

Summary: In this study, we conducted a field experiment to investigate the response of wheat dry matter, photosynthetic characteristics, and yield components to the border effects under hole sowing cultivation. We found specific border effects on each index of five wheat varieties, with XN175 and XN765 showing the most significant effects and highest yield. Our results also identified the net photosynthetic rate and aboveground dry matter per plant as the most influential factors contributing to the border effects.

Summary: The lack of available leaf color mutants in crops has hindered the understanding of photosynthesis mechanisms and limited improvements in crop yield through enhanced photosynthetic efficiency. This study identifies a temperature-sensitive albino mutant, CN19M06, which produces chlorophyll-deficient leaves at temperatures below 10 degrees C. Genetic analysis suggests that the albino phenotype is controlled by a recessive nuclear gene, TSCA1, and molecular linkage analysis narrows down its location to a specific region of chromosome 2AL. The putative candidate gene for TSCA1, TraesC-S2A01G487900, is related to chlorophyll metabolism and temperature sensitivity. Overall, CN19M06 holds great potential for studying the molecular mechanism of photosynthesis and monitoring temperature changes in wheat production.

Summary: Seed vigor is an important trait in wheat breeding, and this study identified multiple quantitative trait loci (QTLs) associated with various seed vigor traits in a doubled haploid population derived from a cross between Yangmai 16 and Zhongmai 895. The QTLs were located on chromosomes 2B, 3D, 4B, 4D, 5A, 5B, 6A, 6B, 6D, 7A, and 7D, explaining significant portions of the phenotypic variances. The study also developed KASP markers for a QTL cluster on chromosome 4D and validated them in a panel of wheat accessions. These findings provide valuable genetic resources for improving seed vigor in wheat breeding programs.

Summary: This study aimed to identify and map the leaf rust resistance of six Canadian Western Red Spring wheat cultivars. Three doubled haploid populations were evaluated for seedling resistance and adult plant disease response and genotyped with a SNP array. Multiple QTL for leaf rust resistance were found in each population, with contributions from different cultivars. The results provide valuable information for resistance breeding and expanding our knowledge of leaf rust resistance genes in Canadian wheat.

Summary: This study investigates the variable mycorrhizal responsiveness in wheat and the potential to breed for improved crop-mycorrhizal symbiosis. The findings reveal significant variation in plant growth response to mycorrhizal inoculation among different wheat lines. Mycorrhizal plants show no decrease in shoot phosphorus concentration with increasing biomass, unlike non-mycorrhizal plants. The identification of several quantitative trait loci (QTL) associated with mycorrhizal responsiveness suggests the possibility of breeding wheat varieties with enhanced symbiosis with arbuscular mycorrhizal fungi.

Summary: This research identified multiple minor QTLs for spot blotch resistance in wheat under Indian subcontinent conditions, with QTLs on chromosome 4B and 5D showing the largest effect. Both RIL mapping populations exhibited quantitative inheritance and transgressive segregation for spot blotch resistance. The presence of newly identified Sb4 and durable resistance gene Lr46 in the identified QTL regions highlights their importance in breeding for spot blotch resistance in Bangladesh and South Asia.

Summary: This study investigated the genetic variability, demography, and divergence period of Bipolaris sorokiniana, a fungal pathogen infecting wheat and barley, by analyzing ITS, GAPDH, and TEF-1 alpha sequences from isolates worldwide. The research revealed a broad and geographically undifferentiated global population of the pathogen, with the H_1 haplotype identified as the ancestral one. Human-mediated dispersal likely played a significant role in shaping the population, with haplogroups originating at the Plio/Pleistocene boundary.

Summary: In this study, the expression patterns of ten stress-responsive miRNAs involved in osmotic stress adaptation were examined in two contrasting wheat genotypes. Three miRNAs were upregulated under stress, while seven miRNAs were downregulated. Additionally, GRAS genes, as targets of these miRNAs, were upregulated during osmotic stress. These findings provide evidence for the differential regulation of miRNAs and their targets in wheat in response to osmotic shock.
