Summary: This study evaluated the changes in male flower development in cucumber under normal and heat stress conditions. It was found that heat stress led to decreased pollen fertility, abnormal tapetum and microspores, and significant changes in gene expression related to carbohydrate metabolism. Additionally, a co-expression network analysis revealed specific hub genes associated with heat stress response.

Summary: Novel regulators underlying high ascorbate content in tomato fruits were identified using forward genetics and mapping-by-sequencing approaches. Mutants with increased ascorbate levels were characterized, revealing a cis-acting upstream open reading frame (uORF) mutation affecting downstream regulation of GDP-L-galactose phosphorylase (GGP). The high ascorbate content was found to impact floral organ architecture, leading to male sterility in tomato plants.

Summary: MutMap and KASP analyses identified the BrGGL7 gene as the responsible gene for the male-sterile trait of ftms1 in Chinese cabbage, and this was further confirmed through functional verification in Arabidopsis. These findings provide important insights into the molecular mechanisms underlying male sterility in Chinese cabbage.

Summary: The SlCHIP gene in tomato plays a critical role in heat stress responses by targeting degradation of misfolded proteins. Silencing of SlCHIP reduces heat tolerance in plants, while its overexpression restores heat tolerance to wild type levels. This suggests that SlCHIP is important in regulating plant responses to high temperature stress.

Summary: Climate change has an adverse impact on vegetable crops, particularly tomatoes, causing changes in physiological and biochemical responses which result in poor fruit quality and low yield. To develop heat-tolerant tomato cultivars, feasible and reliable screening strategies are needed, and the evaluation of various growth parameters can help determine the tomato's tolerance to high temperature.

Summary: Sweet corn varieties showed significant differences in yield, yield components and quality under environmental stress conditions. The study found that the physiological parameter PFR and ABA hormone levels in plants provide important information about stress tolerance levels and plant growth, respectively. Despite adverse conditions, the FCY of the SADA-18.7 variety was higher than that of the control and the experiment's mean value.

Summary: Heat stress is a prevalent negative factor affecting plant growth and development. In this study, the response of tomato phyA and phyB1B2 mutants to high temperatures at different growth stages was investigated. The mutants showed tolerance to heat stress during the seed germination and vegetative growth stages, while their response during the flowering stage was dependent on the duration of heat exposure. The vegetative growth stage demonstrated the highest tolerance, with increased membrane stability and water preservation achieved through stomatal closure regulation. Additionally, both mutants upregulated heat-responsive genes and the phyA mutant showed enhanced proline levels and lower malondialdehyde accumulation.

Summary: Fruit formation is dependent on successful fertilization and is susceptible to weather fluctuations affecting pollination. The auxin hormone plays a role in fruit initiation and growth after fertilization. This study examines the regulation of fruit set and growth by the ARF family in tomato and Arabidopsis, and demonstrates that reducing the activity of SlARF8 genes can improve yield stability in fluctuating temperatures.

Summary: CRISPR-Cas9-based genome editing was used to edit a tomato gene, resulting in the elimination of the PRD and 8CM domains. The edited tomato plants showed increased tolerance to various stresses, including high temperature, osmotic stress, and Pseudomonas syringae pv. tomato infection.

Summary: Global warming is expected to increase in the coming years, leading to frequent heatwaves and hot days worldwide that can have a serious impact on crop growth and productivity. In a pot experiment, the heat tolerance of three tomato cultivars was evaluated, with BARI Tomato-15 showing better heat tolerance compared to the other cultivars under short-term heat stress.

Summary: Climate change poses a significant threat to tomato production, as heat stress negatively affects plant growth and development. This study explores how different tomato cultivars respond to chronic heat stress, focusing on microsporogenesis and pollen germination rate. The results show variations between cultivars in terms of delayed or desynchronized pollen development and abolished pollen germination under heat stress. Transcriptome analysis also reveals common and specific molecular responses of floral buds from different cultivars to cope with chronic heat stress. These findings provide valuable insights for developing climate-resilient tomato varieties.

Summary: Ectopic expression of glutaredoxin S17 from Arabidopsis thaliana (AtGRXS17) in maize enhances chaperone activity and gene expression associated with heat stress, providing thermotolerance. Thermotolerant maize lines showed increased protection against protein damage, resulting in a sixfold increase in grain production under heat stress conditions. These lines also exhibited thermotolerance in the reproductive stages, leading to improved pollen germination and fertilized ovules. The findings offer a robust and simple strategy for meeting rising yield demands in maize and potentially other crop species in a warming global environment.

Summary: Exposure to high temperatures can affect pollen development, but a study shows that reducing the hormone salicylic acid (SA) levels in tomatoes can increase pollen viability under long-term mild heat conditions. This increase in thermotolerance is associated with enhanced jasmonic acid (JA) signaling.
