Virus-induced plasma membrane aquaporin PsPIP2;1 silencing inhibits plant water transport of Pisum sativum.

ABSTRACT:

Background

Aquaporins (AQPs) are known to facilitate water transport across cell membranes, but the role of a single AQP in regulating plant water transport, particularly in plants other than Arabidopsis remains largely unexplored. In the present study, a virus-induced gene silencing (VIGS) technique was employed to suppress the expression of a specific plasma membrane aquaporin PsPIP2;1 of Pea plants (Pisum sativum), and subsequent effects of the gene suppression on root hydraulic conductivity (Lp_r), leaf hydraulic conductivity (K _leaf ), root cell hydraulic conductivity (Lp_rc), and leaf cell hydraulic conductivity (Lp_lc) were investigated, using hydroponically grown Pea plants.

Results

Compared with control plants, VIGS-PsPIP2;1
