Table 5 List of Genes involved in drought tolerance validated function  through Virus induced gene silencing (VIGS) experiment in cotton

GhSnRK2

Sucrose non-fermenting

1-related protein kinase 2

Alleviated drought tolerance

(Bello et al., 2014)

GbMYB5

R2R3-type MYB

transcription factor

Decreased drought tolerance

(Chen et al., 2015)

PHYA1

Improved drought, salt and heat tolerance

(Abdurakhmonov et al., 2014)

GhJUB1L1

(Lu et al., 2021)

GhNAC79

Overexpression led to early flowering and improved drought tolerance in cotton

(Guo et al., 2017)

GhWRKY46
