Summary: Temperature is an important abiotic factor that affects the range, richness, activity, life history, and viability of insects. This study investigated the persistence of thermal stress on the fall armyworm, both biologically and biochemically, across multiple generations. Thermal stress resulted in reduced survival rates, developmental delays, decreased reproductive parameters, and altered metabolic reserves in adults. These findings contribute to a better understanding of the impact of thermal stress on fall armyworm populations under current and future climate change scenarios.

Summary: This study analyzed the response mechanism of waxy corn under low temperature stress. The results showed that the inbred line N28 exhibited higher phenotypic and physiological indices of cold resistance compared to N67. The expression levels of certain genes involved in plant hormones and MAPK pathways were significantly up-regulated in N28 compared to N67, and flavonoid metabolites were also significantly enriched in N28 under low temperature stress. These genes and metabolites may help improve cold resistance in waxy corn and could serve as potential target genes for cold resistance breeding.

Summary: In this study, the researchers introgressed a major QTL, qp1ER1-1, for low temperature germination ability (LTGA) from a tolerant maize line into a sensitive line to generate near isogenic lines. They found that the introgression of qp1ER1-1 improved the LTGA of the near isogenic lines when germinated under cold temperature conditions. Transcriptome analysis revealed the specific expression of LTGA-related genes in the tolerant lines, and identified 27 common LTGA genes that could be located within the confidence interval of qp1ER1-1. This study provides new insight into the molecular mechanism of maize seed LTGA and aids in the cloning of the qp1ER1-1 gene.

Summary: This study compared the development of ABA synthesis-deficient mutant (vp5) and normal maize (Vp5) embryos through ABA content and transcriptome analysis. The results showed that differential ABA synthesis affected seed maturation, and identified gene modules that were negatively correlated with ABA content and involved in metabolic and cellular processes. These findings are important for understanding the molecular mechanism of ABA signaling and developing high dehydration tolerance maize suitable for mechanical harvesting.

Summary: Viral infections cause significant stress on cellular RNA and trigger RNA surveillance pathways. In this study, PB components in Arabidopsis were found to be co-opted by the Cauliflower mosaic virus (CaMV) to facilitate viral replication and translation. This pro-viral role was not associated with RNA decay but instead helped in viral RNA translation. Dysfunctions in PB components exposed the virus to RNA silencing, similar to what has been observed in transgenes. Our study highlights the importance of PB components in maintaining efficient virus translation and their unique dependence on RNA silencing.

Summary: This study investigated the impact of climate variations on grape berry quality by exploiting the consistent differences in radiation and average air temperature between two experimental vineyards. The results showed that warmer climates were associated with carotenoid degradation and lower flavonol contents, while radiation and temperature were closely linked to phenylpropanoid metabolism in the berries. This suggests that warmer climates have potentially harmful effects on grape quality.

Summary: The collapse of certain melon-pumpkin graft combinations may be caused by impairment of photoassimilates transport and imbalance of root auxin and cytokinins. Incompatible combinations show elevated levels of IAA and certain cytokinins in the roots during fruit ripening, while restricting transport of photoassimilates and inducing their accumulation in the scion.

Summary: We describe the dynamic changes in translation that occur during seed maturation, germination, and seedling establishment. Through network analysis, we identified putative regulatory relationships and confirmed some of them in vivo. The construction of SeedTransNet, a regulatory network based on polysome occupancy data, allowed us to predict translational regulatory pathways involving hundreds of genes and specific transcript sequence features suggesting separate regulatory circuits. Our study demonstrated the usefulness of SeedTransNet in identifying regulatory pathways during seed phase transitions.

Summary: Grafting can improve melon fruit yield and quality, but lack of compatibility between rootstock and scion hampers its effect. We studied melon-pumpkin graft combinations with different compatibility levels to assess the impact of rootstock identity on melon fruit yield and quality. Our results showed that rootstock identity (and compatibility level with scion) was associated with increased fruit nutritional values, including high concentrations of organic acids and soluble carbohydrates.

Summary: Seeds play a crucial role in plant reproduction, survival, and dispersal, with germination ability and seedling establishment strongly influenced by seed quality and environmental factors. This study focuses on tomato seeds and explores how genetic variation and the maternal environment impact seed and seedling quality traits and environmental responsiveness at the transcriptome level. By using RNA-sequencing, a genetic map was constructed using a tomato recombinant inbred line population and gene expression was measured for seeds that matured in different nutritional environments. This research provides insight into the genetic landscape of gene regulation in dry seeds and its relationship with the maternal nutrient environment.

Summary: Continuously increasing global temperature could have a significant impact on grape berry metabolite accumulation, wine polyphenol concentration, and color intensity. Field trials were conducted to explore the effect of late shoot pruning on grape berry and wine metabolite composition. The results showed that late pruning treatments had a significant effect on must and wine metabolites, with higher metabolite content observed in the late shoot pruning treatments for Syrah grapes, but not consistently for Malbec grapes. This suggests that late shoot pruning can impact must and wine quality-related metabolites, which may be related to enhanced photosynthetic efficiency, especially in warm climates.

Summary: Grafting the same tomato variety onto different rootstocks results in phenotypic heterogeneity of the scion and highlights the productivity efficiency of M82 regardless of the rootstock. Analysis of metabolites shows that citrate, malate, and aspartate exhibit highly responsive and correlated patterns during grafting, partly related to rootstock origin. Additionally, a consistent group of six metabolites characterizes exceptional graft responses.
