...- and rolled-leaf phenotype in rice. MKB3 was found to be an ortholog of Arabidopsis ANGUSTIFOLIA3 ( AN3 ), which positively regulates cell proliferation. The reduced leaf size of mkb3 plants with enlarged cells and the increased size of MKB3- overexpressing leaves with normal-sized cells indicate that MKB3...

... the cellular processes are coordinated. Here, we used a loss-of-function mutation in the transcriptional coactivator gene ANGUSTIFOLIA3 ( AN3 ), which causes typical compensation in Arabidopsis thaliana . We established Cre/ lox systems to generate leaves chimeric for AN3 expression and investigated whether...
