Summary: Comparative transcriptome profiling of two Chinese wild grape accessions with varying resistance levels to Erysiphe necator revealed a higher proportion of down-regulated genes in the susceptible variety, Hunan-1, at every infection stage. In contrast, the resistant variety, Shang-24, showed a greater number of up-regulated genes, suggesting a potential molecular basis for grape resistance to powdery mildew disease caused by E. necator.

Summary: SUMOylation plays crucial roles in multiple biological processes in eukaryotic organisms. This study reveals the regulatory functions of SUMOylation in low-temperature survival and oxidative DNA damage tolerance during infection in B. cinerea. SUMOylated BcSsb affects the stability of microtubules and consequently mycelial growth at low temperature, while SUMOylated BcRad18 modulates the mono-ubiquitination of pcna involved in oxidative DNA damage response during infection.

Summary: In this study, the genetic structure and diversity of Colletotrichum gloeosporioides, the dominant species causing citrus anthracnose, were analyzed using the Glyceraldehyde-3-phosphate dehydrogenase (GAPDH) gene. A total of 19 GAPDH haplotypes were identified, with the main haplotype (haplotype 5) distributed widely among isolates from different Citrus species and locations. The genetic differentiation index (Fst) revealed significant genetic differentiation between populations from different regions and host species. The results suggest that genetic differentiation in C. gloeosporioides is mainly influenced by gene mutation, recombination, or migration within native populations rather than natural selection caused by geography or host variety.

Summary: This study reveals that a HIPP protein, VvHIPP21, is a functional component of the negative regulator HOS1 in the cold signaling pathway. The expression of VvHIPP21 is suppressed by cold and ABA, but elevated by drought. Ectopic expression of VvHIPP21 in Arabidopsis alleviates metal ion stress, but increases cold sensitivity and reduces drought tolerance.

Summary: This study evaluated the expression differences of the HOS1 gene in different genotypes of cold-tolerant grapes, and found significant differences in the length and promoter sequences of the HOS1 gene between the two grape types. The deletion of a 313-bp region abolished the promoter activity of VvHOS1. Additionally, potential regulatory proteins were identified to interact with the 313-bp core promoter region and regulate GUS gene expression.

Summary: In perennial fruit species, such as grapevine, the phenomenon of somatic embryogenesis (SE) can lead to the formation of deformed embryos, for reasons that are still not well understood. In this study, the authors investigated cotyledonary embryos of grapevine cv. 'Chardonnay' with distinct morphologies to explore this issue. They found that normal cotyledonary embryos (NCEs) and elongated cotyledonary embryos (ECEs) had better-developed vasculature and shoot meristems compared to vitrified cotyledonary embryos (VCEs) and fused cotyledonary embryos (FCEs), but ECEs were less developed. The authors suggested that the morphological differences in these abnormal embryos were likely associated with changes in endogenous hormone levels, particularly indoleacetic acid (IAA) and abscisic acid (ABA). Comparative transcriptome analysis revealed significant differences in gene expression related to hormone signaling pathways in normal and abnormal cotyledonary embryos. Weighted gene co-expression network analysis identified co-regulated gene modules associated with SE, indicating the involvement of ERF family genes and other transcription factors (TFs) in regulating embryonic morphology. Furthermore, the authors found that specific protein kinases, small heat shock proteins (sHSPs), and TFs were closely associated with the formation of normal cotyledonary embryos. This study provides valuable insights into the genetic networks controlling cotyledon development during somatic embryogenesis, opening up new avenues for research on plant regeneration and functional genomics of malformed embryos.
