Summary: Leaf senescence is considered favorable for wheat seed yield improvement, but staying green may be a better strategy for further increasing yields. Comparative transcriptome analysis between two wheat cultivars showed that the stay-green phenotype had higher expression of genes related to leaf senescence, photosynthesis, chlorophyll metabolism, and antioxidative enzyme activity. These findings provide new insight into delaying leaf senescence and improving wheat yields.

Summary: In this study, a pale green mutant was discovered in Chinese cabbage through EMS mutagenesis. The mutant had lower chlorophyll content and higher non-photochemical quenching, with imperfect chloroplast structure. The pale green phenotype was controlled by a recessive nuclear gene, Brpgm, and the target gene was identified as BrCAO, which encodes chlorophyllide a oxygenase (CAO).

Summary: The study focused on the origin of chlorophyll b deficiency in plants, particularly due to a mutation in the CAO enzyme responsible for Chl b synthesis. By characterizing different ch1 mutants and ecotypes, the research explored the strategies plants use to compensate for low chlorophyll content. The results demonstrated significant roles of CAO gene mutations in adjusting the photosynthetic apparatus to low-light conditions and suggested possible ways to regulate chlorophyll conversion under different light stress conditions.

Summary: Seed priming is crucial for improving agricultural crops, and this study compares the effects of hydropriming and iron priming on wheat seedlings. Results show significant differences in germination and seedling characteristics between different priming treatments and wheat genotypes. The synthetically derived wheat line (SD-194) exhibited the most promising attributes compared to other genotypes. Additionally, hydropriming with tap water and priming with low concentrations of iron yielded better results. These findings suggest that seed priming can be an innovative approach for wheat biofortification and enhanced iron accumulation in grains.

Summary: CRISPR/Cas9-mediated knockout of the OsCAO1 gene in rice leads to changes in leaf color, morphology, and chlorophyll content, affecting growth, leaf development, and grain quality characteristics. Knockout of OsCAO1 also influences the gene expression involved in chlorophyll biosynthesis and metabolism, as well as rice grain quality traits such as gel consistency and chalkiness.

Summary: Heat stress is a significant factor affecting wheat production, with eEF1A playing a role in plant heat tolerance. Varieties with higher eEF1A accumulation under heat stress show less decrease in photosynthetic pigments, correlating with better yield traits. This study aims to develop agricultural strategies and heat-tolerant wheat varieties through analyzing molecular mechanisms under high and moderate air temperatures.

Summary: The Rht-B1b gene affects plant architecture and yield traits in wheat, increasing tiller and spike number, as well as grain number. It reduces plant height by decreasing cell size and grain size or weight by decreasing cell number. Transcriptome analysis revealed many key gene homologs and integrators regulated by Rht-B1b for specific traits.

Summary: Reduced chlorophyll b synthesis through antisense expression of CAO leads to decreased chlorophyll b and total chlorophyll content, increased chlorophyll a/b ratio, and reduced rates of electron transport and carbon assimilation in photosynthesis.

Summary: The effects of bacterial endophytes on wheat response to Fusarium head blight (FHB) were studied in a greenhouse experiment. The results showed that the physiological responses of wheat to FHB were strongly influenced by the bacterial endophytes, although the direct effects on disease resistance were weak and dependent on the host variety. Proton motive force traits were identified as potential predictors of disease response. The study suggests an alternative mechanism for microbial biocontrol and proposes potential phenotyping tools for FHB susceptibility in wheat and other small grains.

Summary: This study investigates the photosynthetic performance and yield potential of a new dwarf wheat variety, Xiaoyan 101. Compared with other dwarf wheat varieties, Xiaoyan 101 exhibits higher content of photosynthetic pigments and photochemical efficiency, and lower content of hydrogen peroxide and malondialdehyde in the lower leaves of the canopy. Additionally, the antioxidant enzymes-encoding genes are upregulated while the senescence-associated genes are downregulated in Xiaoyan 101.

Summary: A study on a recombinant inbred line population derived from a cross between two wheat varieties revealed the genetic relation between photosynthesis and grain yield-related traits. A total of 57 QTL associated with these traits were identified, and 12 QTL clusters were found to regulate multiple traits. Additionally, seven QTL clusters were associated with both photosynthesis and grain yield-related traits, and two QTL clusters co-located with reduced-height genes.

Summary: Species of the Magnoliaceae family are prized for their ornamental value and are widely utilized in landscaping around the world. However, many of these species are endangered due to being overshadowed by taller trees in their natural habitats. Our study uncovers the molecular mechanisms behind Magnolia's sensitivity to shade, shedding light on how the plant responds to a lack of light.

Summary: This study investigates the differential expression of two distinct gene copies of chlorophyllide a oxygenase (CAO) in response to light exposure after a period of darkness. The results demonstrate that the accumulation of chlorophyll b (Chl b) is only abolished when both genes are knocked out. The mutant retains pseudo-cyclic electron transport to provide photoprotection for PSI.

Summary: The study demonstrated that quercetin flavonoids have a beneficial effect on physiological processes in wheat seedlings, particularly at a concentration of 3.0%. Most physiological parameters and total antioxidant capacity did not show significant differences in their increase when concentrations of 3.0% and 5.0% were applied, indicating that the beneficial effects of quercetin are already observed at 3.0% concentration.

Summary: This study identified genetic determinants for spike and kernel-related traits in hard winter wheat (HWW) using genome-wide association studies (GWAS). Several significant quantitative trait loci (QTLs) were discovered, including potentially novel ones on chromosomes 1A, 5B, and 7A. The allelic frequencies of important quantitative trait nucleotides (QTNs) were also deduced, providing valuable information for wheat breeding programs. The results from this study can be directly applied by breeders for the selection of favorable alleles and marker-assisted selection of stable QTLs for yield components.

Summary: Nitrogen deficiency and heat stress are major abiotic stresses that affect wheat grain quantity and quality. This study examined wheat varietal response to nitrogen and heat stress, and found that RSI and RNDVI were strongly correlated with grain yield, suggesting their potential use as efficient selection criteria for nitrogen-use-efficient wheat varieties under terminal heat stress conditions.
