Agronomic traits of OsASN1 overexpressing transgenic plants. (A) Morphology of OsASN1 overexpressor lines (OX1 and OX2) and their segregant WT rice plants grown in a conventional paddy field using conventional agricultural practices. Representative photographs were taken before harvest (scale bar = 20 cm). Agronomic traits of WT and OX plants grown in paddy fields, including gran yield per plant grown in paddy fields (n = 5) (B) and 1,000-grain weight (C). Quantification of N (D), protein (E) and amino acid (F) concentrations in grains of WT and OX plants. Data represent mean ± SE of five replicates. Significant differences between OX and WT plants are indicated with an asterisk (*P < 0.05).
