Description | The gene controls early sporogenic development and encodes for a Leucine-rich repeat receptor-like protein kinase. Mutant plants display excessive number of both male and female sporocytes, disordered anther wall layers loss of tapetum layer, arrest of pollen mother cell development in Meiotic phase-I and complete male sterility. Gene expressed in cells surrounding the male and female sporocytes and some flower tissues, but not in the sporocyte cells. msp1 is a ortholog of the EMS1/EXS gene in Arabidopsis. | ||||||||
Curator Comment | In the floret primordium msp1 was expressed in the basal part of lemma, palea, stamen and carpel. |
