Summary: Photosynthetic efficiency of soybean pods and seeds contributes to yield by compensating for carbon loss. This study investigates the photosynthetic efficiency of soybean pods and seeds and its effect on mature seed weight and composition. The results show that soybean pod and seed photosynthesis contributes 13% to 14% of the mature seed weight and can compensate for 81% of carbon loss. Chlorophyll fluorescence analysis reveals the optimal stage for photosystem II efficiency in seeds and pods. This study provides quantitative information about the efficiency of soybean pod and seed photosynthesis during tissue development and its impact on yield.

Summary: The removal of wheat flag leaf significantly reduces the concentration of Pb in grains, where the contribution of flag leaf to grain Pb accumulation decreases gradually with the filling process. The main source of Pb from flag leaves to grains is found to be from atmospheric fallout in fine particles, suggesting that measures to reduce the influence of fine atmospheric particles on wheat could effectively control Pb contamination in wheat grains.

Summary: Drought stress significantly reduces the grain filling duration and yield of wheat, primarily due to decreased current assimilation and insufficient contribution of culm reserves. Water-soluble carbohydrates in culm show reduced contribution to grain yield under stress.

Summary: This study compared the grain moisture content and dehydration rate of coated treatment and control grains to investigate the driving forces and mechanisms of grain dehydration in maize cultivars. The results showed that grain dehydration is mainly driven by filling before physiological maturity, with some water flowing back to the cob via the pedicel xylem.

Summary: Heat stress poses a significant challenge to Australia's barley production, impacting yield and grain quality. Breeding heat-tolerant genotypes is difficult due to the narrow sensitivity window and co-occurrence with drought stress. Understanding traits and mechanisms associated with heat tolerance can help in developing efficient selection methods.

Summary: The SWEET transporters OsSWEET14 and OsSWEET11 play crucial roles in sugar supply for grain filling in rice, with distinct spatial and temporal expression patterns. The absence of OsSWEET14 leads to severe consequences in grain weight and yield, suggesting an important role in the process.

Summary: TaPGS1, a transcription factor belonging to the basic helix-loop-helix family, is specifically expressed during seed development in wheat. Overexpression of TaPGS1 increases grain weight and size, as well as carbohydrate and total protein levels. TaPGS1 regulates the expression of PLATZ transcription factor genes and plays a critical role in cereal grain development.

Summary: Selfing in alfalfa can lead to decreased seed yield, but in fields with higher selfing rates, there was no reduction in seed yield, rather an increase was observed. Pollinator-mediated selfing is the main cause of selfing in alfalfa, and eliminating selfing would require the selection of self-incompatible varieties.

Summary: Low phosphorus availability limits crop productivity in agroecosystems. The flow of phosphorus to developing grains during the grain filling stage determines crop yield. This study found that maize cultivars with higher phosphorus acquisition efficiency contribute more to grain formation and production under low phosphorus conditions.

Summary: In this study, the effects of OsCIPK17 gene on agronomic traits, photosynthetic parameters, transcriptome, and gene expression were analyzed using mutant cipk17 and Nipponbare in field experiments. The results showed that OsCIPK17 was expressed in multiple organs and involved in root, stem, and leaf growth. Knockout of OsCIPK17 resulted in a decrease in grain filling rate and final grain weight, as well as reduced efficiency of Photosystem II. Enrichment analysis and fluorescence analysis further confirmed the functions of OsCIPK17 in photosynthesis and metabolism-related gene expression.

Summary: This study investigated the cold tolerance of sorghum in high altitudes and temperate regions under early, mid, and standard planting dates, finding that delayed panicle initiation and reduced panicle size were the main reasons for decreased grain yields under early and mid-planting dates. The study revealed that panicle width and area were significant predictors of yield under early and mid-planting dates.

Summary: A soybean population of 364 RILs was used to identify QTLs associated with 100-SW, PL, and PW. Moderate correlations were observed among these traits, with the strongest correlation between 100-SW and PW. QTLs for these traits were identified using various methods, with 189 novel QTLs discovered and 24 detected by multiple methods.

Summary: The study characterized the traits governing seed yield in five mungbean genotypes under waterlogging stress and identified potential indicators for screening mungbean genotypes. It was found that waterlogging significantly reduced various morphological and physiological traits, including leaf count, plant height, and seed weight. A positive correlation was observed between seed yield and photosynthetic rates, stomatal conductance, and chlorophyll content, while a negative correlation was found with excitation pressure.

Summary: Agronomic practices can improve seed production and yield in smooth bromegrass by regulating seed yield components. Key findings from the study indicate that fertile tillers have a positive impact on seed yield, while seed number has a negative effect. Additionally, phosphorus application can increase spikelets and seed number under conditions of sufficient nitrogen.

Summary: The demand for high-quality forage has increased in China due to the development of animal husbandry. However, efficient planting regimes and key technologies are lacking, which limits the production of high-quality forage. This study developed a two-sown regime for oat forage production in an alpine region of China and found that it significantly increased the yield and nutritional value of the forage compared to traditional one-sown regimes. The key technologies of the two-sown regime were identified, and it was suggested that this planting regime could be widely used in northern China and similar regions.

Summary: Long-term mowing significantly affects the community structures of plants and soil microbial groups. The microbial communities are mainly correlated with plant parameters rather than soil properties. Furthermore, plant beta-diversity regulates the beta-diversity of soil microbial communities.
