VvSNAT1 overexpression enhances melatonin production and salt tolerance in transgenic Arabidopsis.

Melatonin (N-acetyl-5-methoxytryptamine) plays important roles in the regulation of development and the response to biotic and abiotic stresses in plants. Serotonin-N-acetyltransferase (SNAT) functions as a key catalytic enzyme involved in melatonin biosynthesis. In this study, the candidate gene VvSNAT1 (SNAT isogene) was isolated from grape (Vitis vinifera L.

Genome-wide characterization and analysis of bHLH transcription factors related to anthocyanin biosynthesis in spine grapes (Vitis davidii).

As one of the largest transcription factor family, basic helix-loop-helix (bHLH) transcription factor family plays an important role in plant metabolism, physiology and growth. Berry color is one of the important factors that determine grape quality. However, the bHLH transcription factor family's function in anthocyanin synthesis of grape berry has not been studied systematically.

Genome Assembly and Transcriptome Analysis of the Fungus During Infection on Grapevine ( L.).

Grape white rot caused by (Speg.) affects the production and quality of grapevine in China and other grapevine-growing countries. Despite the importance of as a serious disease-causing agent in grape, the genome information and molecular mechanisms underlying its pathogenicity are poorly understood.

New quantitative trait locus (QTLs) and candidate genes associated with the grape berry color trait identified based on a high-density genetic map.

Background: Berry color is an important trait in grapes and is mainly determined by the anthocyanin content and composition. To further explore the coloring mechanism of grape berries, the F1 population of Vitis vinifera 'Red Globe' × 'Muscat Hamburg' was used to map the color locus, and transcriptome analysis was performed to assist in screening candidate genes.

Results: A total of 438,407 high-quality single-nucleotide polymorphisms (SNPs) were obtained from whole-genome resequencing (WGS) of the population, and 27,454 SNPs were selected to construct a high-density genetic map.

Construction of a High-Density Genetic Map and Mapping of Firmness in Grapes ( L.) Based on Whole-Genome Resequencing.

Berry firmness is one of the most important quality traits in table grapes. The underlying molecular and genetic mechanisms for berry firmness remain unclear. We constructed a high-density genetic map based on whole-genome resequencing to identify loci associated with berry firmness.

Transcriptome analysis reveal the putative genes involved in light-induced anthocyanin accumulation in grape 'Red Globe' (V. vinifera L.).

The color of berry skin is an important economic trait of grape, which is determined by the composition and concentration of anthocyanins. The anthocyanin accumulation of grape berry skin is affected by light. In order to further explore the mechanisms of light regulation on anthocyanin accumulation in grape, we detected anthocyanin by UPLC-MS and performed transcriptomic analysis using red grape Vitis vinifera cv.
