Effect of overexpression of <i>OsEXPA8</i> on the root system architecture and plant growth.

Abstract

<p>(A) The length of primary roots of seven-day-old rice seedlings. (B) The number of lateral roots of seven-day-old rice seedlings. (C) The plant height of two -month-old rice plants. (D) The leaf number per plant of two-month-old rice plants. (E) The length of the flag leaf of two-month-old rice plants. (F) The width of the flag leaf of two-month-old rice plants. Three independent transgenic line 1 (L1), line 4 (L4) and line 5 (L5) were analyzed. WT: wild-type. Values are the means of ten biological replications ± standard error. One independent plant was considered as one biological replication. Asterisks (*) indicate parameters of <i>35S::OsEXPA8</i> transgenic plants were significantly different from that of wild-type plants by statistical analysis using the Student’s <i>t</i>-test program (<i>P</i><0.01).</p
