EXS, a putative LRR receptor kinase, regulates male germline cell number and tapetal identity and promotes seed development in Arabidopsis.

Journal article

BACKGROUND: Plant germlines arise late in development from archesporial initials in the L2 layer of the anther and ovule primordia. These cells generate a radially symmetrical array of tissues that, in the Arabidopsis anther, comprises a core of sporogenous cells (meiocytes) and the enveloping tapetum, middle cell, and endothecium layers. The putative transcription factor NZZ/SPL is required for the specification of archesporial cells, but nothing is known of how their number is regulated, o...
