A classical role of the hormone auxin is in the formation of flowers at the periphery of the reproductive shoot apex.In Arabidopsis, mutants in regulators of polar auxin transport or in the auxin responsive transcription factor MONOPTEROS (MP) form naked inflorescence pins lacking flowers.How auxin maxima and MP direct initiation of flower primordia is as yet poorly understood.We have identified three genes whose expression is directly induced by auxin-activated MP that jointly regulate flower primordium initiation.

The number of grains produced per inflorescence is a critical determinant of yield in rice.During inflorescence development, meristems grow as a branch to generate further meristems which then termina
Correct timing of the floral transition plays a critical role for reproductive success.In Arabidopsis thaliana,FLOWERING LOCUS T (FT) protein as part of florigen moves from leaves to the shoot apex to
CLE peptides play role in the regulation of various types of meristems: SAM, RAM, cambium, nodule meristems, and meristem-like structures as galls and tumors.CLE peptides were divided into two groups:
