Transcriptome analysis provides new insights into the berry size in ‘Summer Black’ grape under a two-crop-a-year cultivation system

Pei-Yi Ni, Shengdi Yang, Yunzhang Yuan, Chunyang Zhang et autres

Southern China has high temperatures and receives concentrated rainfall; therefore, the two-crop-a-year cultivation system has been applied to grape production so as to resolve the problem of relative seasonal surplus of grape yield. However, a common issue associated with this technique is …

Regulatory Mechanism of Proanthocyanidins in Grape Peels Using vvi-miR828a and Its Target Gene VvMYBPA1

Lingqi Yue, Jingjing He, Tian Gan, Songtao Jiu et autres

Anthocyanins and proanthocyanidins are considered to be essential secondary metabolites in grapes and are used to regulate metabolic processes, while miRNAs are involved in their synthesis of anthocyanins and proanthocyanidins to regulate metabolic processes. The present research work was carried out to …

Comparative transcriptome analysis of genes involved in paradormant bud release response in ‘Summer Black’ grape

Shaogang Fan, Feixiong Luo, Meijun Wang, Yanshuai Xu et autres

Grapevines possess a hierarchy of buds, and the fruitful winter bud forms the foundation of the two-crop-a-year cultivation system, yielding biannual harvests. Throughout its developmental stages, the winter bud sequentially undergoes paradormancy, endodormancy, and ecodormancy to ensure survival in challenging environmental conditions. …

Pectate Lyase Gene VvPL1 Plays a Role in Fruit Cracking of Table Grapes

Jun Yu, Rong Wang, Wentao Ma, Shumin Lei et autres

Fruit cracking seriously affects the commercial value of table grapes. To explore whether cell wall disassembly influences grape berry cracking, first, the differences in the cell wall metabolism were compared between cracking-resistant “Shennongjinhuanghou” (SN) and cracking-susceptible “Xiangfei” (XF) varieties. Our results showed …
