Summary: The interaction of salinity and waterlogging with elevated CO2 affects the phenotypes of tomatoes, with elevated CO2 alleviating the negative impact of stresses on cultivated tomato. The response of tomatoes depends on genotype and stress type, and elevated CO2 can increase photosynthesis and biomass of cultivated tomato under salinity and combined stress.

Summary: This study investigated the effects of low temperature on hormone content, antioxidant activity, and gene expression patterns in two tomato species. The results showed that low temperature led to differential changes in hormone content and gene expression, as well as induction of oxidative stress. Cytokinin was identified as a key hormone associated with the response to low temperature, and glutathione peroxidase played a major role in scavenging reactive oxygen species induced by low temperature, with antioxidants being more induced in tolerant species.

Summary: In this study, we conducted comprehensive selection sweeps of 53 tomato varieties and 166 large-fruited tomato germplasm resources using three selection strategies. We identified 390 potential selection sweeps, some of which had significant effects on fruit-related traits and were crucial to the pseudo-domestication process. We also discovered a minor-effect allele of the SlLEA gene related to fruit weight, as well as major haplotypes of fw2.2/CNR, fw3.2/SlKLUH, and fw11.3/CSR in cultivars. Additionally, we found loci significantly associated with fruit weight and six fruit-related agronomic traits through genome-wide association studies. By examining population differentiation, we identified causative variations underlying the divergence of fruit flavonoids and validated the gene SlBES1.2 as a potential regulator of flavonoid content. Our results provide new insights into the genetic basis of fruit traits and valuable genomic resources for tomato genomics-assisted breeding.

Summary: This study investigated the mechanisms of fruit pigment formation and its relationship with different loquat species through metabolomics and transcriptomics analyses. The results showed that abundant carotenoid deposition in cultivated loquat peel is correlated with the strong expression of PSY, ZDS, and ZEP genes, while the accumulation of anthocyanins in wild loquat peel is tightly associated with upregulated expressions of F3H, F3'H, ANS, CHS, and CHI genes.

Summary: Cyanobacteria play important roles in soil nitrogen fixation, fertility, and water retention, and produce bioactive metabolites beneficial for plants against fungal pathogens. Water extract and phycobiliproteins from Anabaena minutissima showed antifungal activity against Botrytis cinerea, reducing disease severity in tomato fruits and in vitro. The study indicated that these compounds could potentially be used for plant disease control in the future.

Summary: This study reveals the impact of triazole fungicides on metabolic pathways in tomato fruits. Triazole treatment led to changes in free proteinogenic amino acids and saccharide content, increased total phenolics and flavonoids, and stimulated the non-enzymatic antioxidant system. Foliar application of penconazole had the greatest effect on the fruits.

Summary: In this study, we investigated the changes in the transcriptome and epigenome of a long shelf-life tomato landrace during post-harvest. We discovered global changes in the transcriptome and epigenome, with increased DNA methylation and loss of a repressive histone mark. Thousands of genes showed differential expression, with a significant portion potentially being regulated by epigenetic mechanisms. Down-regulation of genes related to fruit ripening and softening was consistent with the prolonged shelf-life. Large-scale epigenome reprogramming during post-harvest likely contributes to delayed fruit senescence.

Summary: This study aims to analyze the genetic variation patterns of two large germplasm collections of Timilia and Russello durum wheat landraces using SNP genotyping. The results showed that there are two genetic groups of Russello associated with different geographical areas in Sicily, which differ in important traits related to gluten quality and adaptation. Meanwhile, Timilia landraces have undergone conservative selection despite their wide genetic variation, likely associated with their distinctive traits. This study provides a foundation for further exploration of the genetic diversity in Sicilian landraces and emphasizes the importance of considering intra-population genetic diversity when registering conservation varieties in national crop registers.

Summary: In this study, the tolerance traits of a tomato line carrying a small region of the Solanum pennellii wild genome (IL12-4-SL) were analyzed. The results showed that IL12-4-SL exhibited higher heat tolerance and produced more flowers with higher pollen viability compared to the cultivated line M82. Water stress had a greater negative impact on photosynthesis than heat stress alone, and the combined stress did not further worsen the drought's effects on this trait. The improved tolerance of IL12-4-SL to single and combined abiotic stress suggests its potential for cultivation in a climate characterized by frequent heatwaves and low rainfall.

Summary: Climate change is a major problem for agricultural crops, and breeding heat-tolerant genotypes is an important strategy to reduce yield losses. In this study, the whole genome of a heat-tolerant tomato genotype (E42) was investigated to identify candidate genes involved in its response to high temperature. Variants with high and moderate impact on protein function were found in genes related to heat tolerance and reproduction. This study provides valuable information on the genetic background and heat stress response of E42.
