XAt1g59640842254ZCW32A basic helix-loop-helix encoding gene (BIGPETAL, BPE) involved in the control of petal size. BPE is expressed via two mRNAs derived from an alternative splicing event. The BPEub (AT1G59640.1)transcript is expressed ubiquitously, whereas the BPEp (AT1G59640.2) transcript is preferentially expressed in petals. Plants that lack the petal-expressed variant BPEp have larger petals as a result of increased cell size. BPEp is positively regulated downstream of APETALA3, PISTILLATA, APETALA1 and PISTILLATA3 and is negatively regulated downstream of AGAMOUS.O.I.H.G.
XAt2g01500814678PFS2 (PRETTY FEW SEEDS 2)PFS2 encodes a homeodomain gene that is a member of the WUS clade of transcription factors. It delays differentiation and maturation of primordia and regulates ovule patterning. The pfs2 mutant exhibits developmental defects in the maternal integuments and gametophyte, specifically, the boundary between the chalaza and the nucellus shifted towards the distal end of pfs2 ovule primordia. In addition, leaves displayed curling and petals were wavy and crenulated. Overexpression of PFS2 affects floral organ and leaf development. Single- and double-mutant analyses reveal that PFS2 activity represses AGAMOUS expression in young floral primordia. Also involved in regulation of response to low temperature.O.I.H.G.



The upper GO terms

Process ID Gene number Process name
GO:004844113The process whose specific outcome is the progression of the petal over time, from its formation to the mature structure.
GO:00484443The process by which the anatomical structures of the floral organ are generated and organized. Morphogenesis pertains to the creation of form.



The lower GO terms

Process ID Gene number Process name
GO:00484513The process that gives rise to the petal. This process pertains to the initial formation of a structure from unspecified parts.
GO:00484520The process that contributes to the act of creating the structural organization of the petal. This process pertains to the physical shaping of a rudimentary structure.
GO:00484981The process that determines the orientation of petals with reference to the central axis.
