Dynamics of small RNAs in a red-fruited wine grape cultivar infected with Grapevine red blotch virus.

ABSTRACT:

Background

Red blotch disease, caused by Grapevine red blotch virus (GRBV, genus Grablovirus, family Geminiviridae), negatively impacts vine health, fruit yield, and quality, leading to substantial economic losses to growers. While recent studies have enhanced our understanding of the epidemiology of GRBV and its effects, little is known about the molecular basis of the host-virus interactions. Since small RNAs (sRNAs) are known to play a central role in host-virus interactions, this study was undertaken to investigate sRNA dynamics in leaves and berries at two phenological stages (asymptomatic pre- and symptomatic post-véraison) of GRBV-infected grapevines (Vitis vinifera cv. Merlot).

Results

Among the 140 microRNAs (miRNAs) detected, 41 isoforms belonging to 18 miRNA famil
