PTL | Trihelix transcription factor PTL; Transcription factor that prevents growth. Regulates perianth architecture in flower, mostly in the second whorl, probably by suppressing growth between initiating sepals, ensuring that they remain separate, and by modulating organ shapes. Required for the establishment of auxin flux. (591 aa) | ||||
BOB1 | Protein BOBBER 1; Small heat shock protein required for the establishment of auxin gradients and for patterning of the apical domain of the embryo. Involved in the specification of the cotyledon primordia. Also required for normal inflorescence and floral meristem function, normal developmental patterning and thermotolerance. Acts as a molecular chaperone. (304 aa) | ||||
ACR4-2 | Serine/threonine-protein kinase-like protein ACR4; Controls formative cell division in meristems, including root tips and lateral root initiation zones of the pericycle, in response to CLE40 signal. Acts with CLE40p peptide as a ligand-receptor pair in a signal transduction pathway, coordinating movement of the root tip and organization of cell divisions in the root meristem. Required during embryogenesis and development, probably for the differentiation of protoderm and epidermal cells. Involved in the regulation of cellular organization during the development of sepal margins and ovu [...] (895 aa) | ||||
BLH9 | BEL1-like homeodomain protein 9; Transcription factor that is involved in the preservation of the spiral phyllotactic arrangement leading to a regular pattern of organ initiation. Required for maintenance of stem cell fate in the shoot apical meristem, and is essential for specifying floral primordia and establishing early internode patterning events during inflorescence development. Acts as transcription repressor of AG expression in floral and inflorescence meristems. Is also responsive of the nuclear import of SHOOT MERISTEMLESS (STM). In the fruit, plays a central role in patternin [...] (575 aa) | ||||
NPR5 | Regulatory protein NPR5; May act as a substrate-specific adapter of an E3 ubiquitin- protein ligase complex (CUL3-RBX1-BTB) which mediates the ubiquitination and subsequent proteasomal degradation of target proteins (By similarity). Acts redundantly with BOP2. BOP1/2 promote leaf and floral meristem fate and determinacy in a pathway targeting AP1 and AGL24. BOP1/2 act as transcriptional co-regulators through direct interaction with TGA factors, including PAN, a direct regulator of AP1. Controls lateral organ fate through positive regulation of adaxial-abaxial polarity genes ATHB-14/PHB [...] (491 aa) | ||||
NPR6 | Regulatory protein NPR6; May act as a substrate-specific adapter of an E3 ubiquitin- protein ligase complex (CUL3-RBX1-BTB) which mediates the ubiquitination and subsequent proteasomal degradation of target proteins (By similarity). Acts redundantly with BOP2. BOP1/2 promote leaf and floral meristem fate and determinacy in a pathway targeting AP1 and AGL24. BOP1/2 act as transcriptional co-regulators through direct interaction with TGA factors, including PAN, a direct regulator of AP1. Controls lateral organ fate through positive regulation of adaxial-abaxial polarity genes ATHB-14/PHB [...] (467 aa) |
