Ectopic expression of a Brassica rapa AINTEGUMENTA gene (BrANT-1) increases organ size and stomatal density in Arabidopsis.

ABSTRACT: The AINTEGUMENTA-like (AIL) family plays a central role in regulating the growth and development of organs in many plants. However, little is known about the characteristics and functions of the AIL family in Chinese cabbage (Brassica rapa L. ssp. pekinensis). In this study, a genome-wide analysis was performed to identify the members of the AIL family in Chinese cabbage. We identified three ANT genes and six ANT-like genes of Chinese cabbage, most of which were differentially expressed in different organs or tissues. Furthermore, compared with the wild-type line, the size of different organs in the 35S-BrANT-1 line was significantly increased by promoting cell proliferation. Meanwhile, over-expression of BrANT-1 also increases the stomatal number and delays the leaf senescence. Transcript
