Analysis of OsWRKY11-ox and RNAi (kd) plants. OsWRKY11-ox lines and OsWRKY11-kd lines of Nipponbare cultivar were generated. Over-expression (a) and knock-down (b) of OsWRKY11 in these lines were confirmed by RT-PCR with gene-specific primers against OsWRKY11 (Table S1). Growth retardation of OsWKRY11-ox transgenic rice at the seedling and tillering stages. The photograph shows 10-day-old seedlings grown in MS medium(c). The relative heights of OsWKRY11-ox transgenic plants were obtained by comparing 10-day-old transgenic and WT seedlings grown in MS medium, and 10-week-old transgenic and WT plants at the tillering stage grown in a greenhouse (d).
