Summary: In this study, genotypic information and heritability estimates were used to identify genomic regions associated with growth traits in Red Angus cattle. Pleiotropic QTL regions were discovered, and positional candidate genes previously associated with feed efficiency and growth traits in beef cattle were also found to be associated with Red Angus growth traits. Additionally, significant genotype-by-environment (GxE) interactions were detected, implicating the role of vasodilation, metabolism, and the nervous system in genetic sensitivity to environmental stress.

Summary: In this study, 20-year-old Castanopsis hystrix experimental forests in Yulin, Liuzhou, and Pingxiang, Guangxi Province, China were used to assess the genetic variations and estimate the genetic parameters of growth and morphological traits. The average values for tree height, diameter at breast height (DBH), volume, height to live crown base (HCB), crown width (CW), and branch angle were determined. The block and family were found to be the most important sources of variance for growth and morphological traits, and the genotype x environment interaction effects were significant. Family heritability was also calculated for each trait. Excellent families with strong adaptability and genetic stability were identified using BLUP-GGE biplots. The results of this study provide a theoretical basis for efficient cultivation of C. hystrix in South China.

Summary: Currently, the effectiveness of QTL mapping depends on the quality of phenotypic data, and the sample size and mapping method also influence the results. Experimental results show that phenotypic data from 5 plants per genotype are sufficient for QTL mapping of traits with high or moderate heritability, and the genotype-based mapping method is more powerful.

Summary: A novel 3D reaction-diffusion model revealed that movement of mesophyll chloroplasts in C-4 plants increased photosynthesis rate but also increased leakiness. A 3D leaf model was developed to investigate how chloroplast movement affects the CO2 concentrating mechanism. Results showed that movement of chloroplasts towards bundle sheath cells increased light absorption, while avoidance movement decreased it. ATP, NADPH production, and net photosynthetic rate increased for aggregative movement and decreased for avoidance movement. Leakiness increased in both scenarios due to energy imbalance.

Summary: Measuring leaf day respiration (R-d) has always been a challenge, but recent research progress using chlorophyll fluorescence and considering CO2 reassimilation has improved the accuracy of estimation. Furthermore, the latest evidence suggests that CO2 and energy release from the oxidative pentose phosphate pathway in chloroplasts is important for understanding R-d.

Summary: The use of insect-proof net tunnels can reduce virus infection in sweetpotato seed produced by decentralized seed producers. This study compared the effect of ratoon cropping technique on vine production in net tunnels and open fields for two varieties of virus-tested sweetpotato. The ratoon cropping technique produced more vines than the replanting technique, but also led to higher virus incidences in plants grown in the open fields, particularly for the Mataya variety. The study recommends using the ratoon cropping technique in net tunnels and the replanting technique in open fields to control virus infections.

Summary: The balanced segregation of homologous chromosomes is crucial for fertility during meiosis. A reduction in crossover (CO) number can lead to unpaired chromosomes and the production of unbalanced, sterile gametes. However, if combined with another meiotic alteration, it can result in uniform, non-recombinant gametes. In potato, a recessive trait known as CO shortage has been mapped to chromosome 8. This study has identified StMSH4 as a candidate gene for CO shortage and discovered nonfunctional alleles in potato cultivars, providing breeders with options for improving fertility or producing uniform gametes.
