Auxin-responsive protein SAUR67; May promote auxin-stimulated organ elongation, such as hypocotyls, stamen filaments and petals. Belongs to the ARG7 family.

GLABRA2 expression modulator; Involved in the spatial control of cell division, patterning and differentiation of Arabidopsis root epidermal cells. Could be part of a complex that negatively modulates GLABRA2 and CAPRICE expression via the maintenance of a repressor histone H3 epigenetics status of the GL2 and CPC promoters.

3-hydroxybutyryl-CoA dehydrogenase-like protein.

Transcription factor BIM3; Positive brassinosteroid-signaling protein.

Transcription factor PAR2; Atypical bHLH transcription factor that acts as negative regulator of a variety of shade avoidance syndrome (SAS) responses, including seedling elongation and photosynthetic pigment accumulation. Acts as direct transcriptional repressor of two auxin-responsive genes, SAUR15 and SAUR68. May function in integrating shade and hormone transcriptional networks in response to light and auxin changes.

Enoyl-CoA delta isomerase 2, peroxisomal; Able to isomerize both 3-cis and 3-trans double bonds into the 2-trans form in a range of enoyl-CoA species. Essential for the beta oxidation of unsaturated fatty acids. Involved with IBR1 and IBR3 in the peroxisomal beta-oxidation of indole-3- butyric acid (IBA) to form indole-3-acetic acid (IAA), a biologically active auxin.

Vacuolar protein sorting-associated protein 29; Plays a role in vesicular protein sorting. Component of the membrane-associated retromer complex which is essential in endosome-to- Golgi retrograde transport. Required for the auxin-carrier protein PIN2 sorting to the lytic vacuolar pathway and the PIN1 recycling to the plasma membrane. Also involved in the efficient sorting of seed storage proteins globulin 12S and albumin 2S. The VPS29-VPS26-VPS35 subcomplex may be involved in recycling of specific cargos from endosome to the plasma membrane.

Transcription factor BIM2; Positive brassinosteroid-signaling protein.

Phosphatidate phosphatase PAH1; Magnesium-dependent phosphatidate phosphatase which catalyzes the dephosphorylation of phosphatidate to yield diacylglycerol. Acts redundantly with PAH2 to repress phospholipid biosynthesis at the endoplasmic reticulum (ER). May function indirectly as repressor of multiple enzymes involved in phospholipid biosynthesis. Is involved in the pathway of galactolipid synthesis in the ER, which is required for the membrane lipid remodeling, an essential adaptation mechanism to cope with phosphate starvation; Belongs to the lipin family.
