Summary: Wheat leaf senescence is a complex developmental process influenced by plant hormones and environmental factors, with direct impacts on grain yield and protein content. Early senescence is associated with high protein content, while late senescence is related to high yield. The regulation of senescence involves multiple genes and is influenced by external, internal factors, and genotypic variations.

Summary: This study investigated leaf rust of wheat in the North-Western Region of Russia and found temporal variation in the virulence of the Puccinia triticina pathogen. Virulence to certain genes decreased over time, while virulence to Lr1 increased. Variability in virulence was observed for other genes as well. The overall trend in recent years has been a reduction in the virulence of the Pt pathogen.

Summary: The current study investigated the effects of wheat straw aqueous extract on bermudagrass, a model of harmful weeds for the wheat crop. The extract significantly decreased germination percentage and index, and affected morphological growth parameters of bermudagrass seedlings. Analysis revealed the presence of phenolic acids and flavonoids in the extract. The highest extract concentrations resulted in a decrease in chlorophyll content and an increase in free amino acids, total protein, and soluble carbohydrates.

Summary: Winter wheat is mainly grown in the North Caucasian, Central Black Earth, and Central agroecological regions in Russia, while spring wheat dominates in the Urals, Volga region, and Western Siberia. Wheat leaf rust, caused by Puccinia triticina, is an important disease affecting wheat production. Research shows that the evolution of the wheat leaf rust pathogen occurs more frequently in regions where pathotype-specific resistance cultivars are commonly grown.

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 evaluated the leaf rust resistance of 50 Egyptian wheat varieties and identified 28 leaf rust resistance genes within the germplasm collections. Most varieties showed high to moderate levels of resistance, with some displaying fast rusting behavior. 21 out of 28 tested Lr genes were successfully identified, including only five genes conferring adult plant resistant or slow rusting behavior in the Egyptian collection.

Summary: Mesophyll conductance (g(m)) is negatively correlated with the age of wheat leaves but positively correlated with the surface area of chloroplasts exposed to intercellular airspaces (S-c). The decline in photosynthetic rate and g(m) is slower for water-stressed plants as leaves age compared to well-watered plants. The recovery from water stress upon rewatering depends on leaf age, with the strongest recovery for mature leaves.

Summary: Resistance Quantitative Trait Loci (QTLs) to leaf rust and powdery mildew were identified in a recombinant inbred line (RIL) population of wheat, with potential new sources of resistance being discovered. Major QTLs were found in response to Blumeria graminis and Puccinia triticina, possibly representing novel functional resistance genes. Polymorphisms between known resistance loci and identified QTLs suggest the presence of new allelic variants in wheat.

Summary: This study investigated the evolutionary and functional divergence of the leaf rust resistance gene Lr21 in diploid and hexaploid wheats through population genetics and high-resolution comparative genomics. The research identified original Lr21 alleles in Aegilops tauschii and discovered a new Lr21-tbk allele in hexaploid wheat cv. Tobak. In addition to seedling resistance, the Lr21 gene was found to confer adult plant field resistance in wheat, with resistance correlated with developmentally dependent variation in Lr21 expression.

Summary: TaNAC69-B is a gene in wheat that is involved in leaf senescence. Overexpression of TaNAC69-B leads to precocious leaf senescence, while its suppression delays leaf senescence. By regulating the expression of ABA biosynthesis genes, TaNAC69-B is involved in the regulation of leaf senescence in wheat.

Summary: Wheat flag leaves have higher stomatal density on the adaxial surface compared to the abaxial surface. Mesophyll cells on the adaxial surface have higher photosynthetic capacity and stomatal conductance. There is some coordination between the two leaf surfaces, but factors other than light intensity also play a role in stomatal kinetics.

Summary: This study introgressed the novel wheat powdery mildew and stripe rust resistance genes Pm5V/Yr5V from Dasypyrum villosum and fine mapped them to a narrowed region in 5VS. The results showed that the Pm5V/Yr5V lines have the potential value to facilitate wheat breeding for disease resistance and do not incur a yield penalty in diverse wheat genetic backgrounds.

Summary: Winter hardiness in wheat is influenced by various environmental factors, with freezing tolerance being a key factor. In this study, the growth response of different wheat cultivars to low temperatures during the acclimation period was studied. The results showed variations in thermal growth patterns among the cultivars, and a correlation was found between leaf growth parameters and freezing tolerance. The findings highlight the importance of growth rate patterns in determining winter hardiness.

Summary: This study investigated the impact and wetting dynamics of droplets on hydrophobic surfaces by using cationic surfactants with different double-chain lengths. It was found that the ability to restrain retraction and promote wetting initially increased and then decreased as the surfactant chains extended. This work provides insights into the mechanism of droplet impact and wetting dynamics and highlights the potential application of surfactants in pesticide spraying.

Summary: Porous materials with nanometer-scale pores have important applications as nanoporous membranes. In this study, ABA triblock copolymers were used as precursors to produce nanoporous polymeric membranes (NPMs) in thin film form by degrading the end blocks. Polycyclooctene (PCOE) NPMs with tunable pore sizes were successfully prepared using solvent casting technique. Oxygen plasma etching was employed to improve the surface porosity and hydrophilicity of the membranes. This study provides a straightforward method to produce tough NPMs with high porosity and hydrophilic surface properties.
