Expression analysis of GmWRP1. (A) Expression of GmWRP1 in different plant tissues. Young leaves, stems, and roots were collected from 4-week-old seedlings at vegetative (V) 2 stage; blooming flowers were sampled from plants at reproductive (R) 2 stage; and pods and seeds were collected at R3 and R7 stages, respectively. (B) Age-regulated expression of GmWRP1 in soybean leaves. The first trifoliolate leaves were collected from 2-week-old seedlings (V1 stage) to 11-week-old plants (R7 stage) at 1-week intervals. GmWRP1 expression was analysed by quantitative qRT-PCR using a soybean actin gene as an internal control.
