Alterations in aerial phenotypes of transgenic SlWRKY23 over-expressing Arabidopsis lines. Transgenic SlWRKY23 over-expressing lines were monitored at different stages throughout the course of their life cycle. Phenotypic analysis was carried out on 15 plants per line. Data represent mean values ± SE. Significant differences are shown as *P < 0.05; **P < 0.01 and ***P < 0.001. a Germination (n = 100), b leaf number, c Rosette diameter, d flowering time, e inflorescence height, f number of inflorescence branches, g number of seeds per silique, h 1000 seed weight, i seed yield, j root dry weight at harvest
