Strigolactone esterase D14; Involved in strigolactone signaling pathway. Does not move long distances acropetally in the plant to regulate shoot branching and is rapidly degraded in the presence of strigolactones. Functions downstream of strigolactone synthesis, as a component of hormone signaling and as an enzyme that participates in the conversion of strigolactones to the bioactive form. Acts probably as a strigolactone receptor. Strigolactones are hormones that inhibit tillering and shoot branching through the MAX-dependent pathway, contribute to the regulation of shoot architectura [...]

Probable esterase KAI2; Involved in seed germination and seedling development. Essential for plant responses to karrikins, a class of butenolide compounds, structurally similar to strigolactones, released from burning vegetation that stimulate seed germination and enhance seedling photomorphogenesis. KAI2 is not required for strigolactone-mediated responses, but MAX2 is necessary for responses to karrikins and strigolactones. Lacks detectable hydrolase activity against karrikin. Karrikin binding induces a conformational change.

Dolichyl-diphosphooligosaccharide--protein glycosyltransferase subunit DAD2; Subunit of the oligosaccharyl transferase (OST) complex that catalyzes the initial transfer of a defined glycan (Glc(3)Man(9)GlcNAc(2) in eukaryotes) from the lipid carrier dolichol- pyrophosphate to an asparagine residue within an Asn-X-Ser/Thr consensus motif in nascent polypeptide chains, the first step in protein N-glycosylation. N-glycosylation occurs cotranslationally and the complex associates with the Sec61 complex at the channel-forming translocon complex that mediates protein translocation across the [...]

Carotenoid cleavage dioxygenase 7, chloroplastic; Involved in strigolactones biosynthesis by cleaving asymmetrically a variety of linear and cyclic carotenoids at the 9-10 double bond. Produces one C(13) beta-ionone and the C(27) 10'-apo-beta- carotenal. Strigolactones are hormones that inhibit tillering and shoot branching through the MAX-dependent pathway, contribute to the regulation of shoot architectural response to phosphate-limiting conditions and function as rhizosphere signal that stimulates hyphal branching of arbuscular mycorrhizal fungi and trigger seed germination of root [...]

Cytochrome P450 711A1; Converts carlactone to carlactonoic acid by catalyzing consecutive oxidations at C-19 to convert the C-19 methyl group into carboxylic acid. Prefers 11R-carlactone to 11S- carlactone as substrate. Acts downstream of CCD7/MAX3 and CCD8/MAX4 in strigolactone signaling pathway and may be implicated in synthesis of carotenoid-derived branch regulators. Acts as a positive regulator of the flavonoid pathway in the late vegetative stage plant. Strigolactones are hormones that inhibit tillering and shoot branching through the MAX-dependent pathway, contribute to the regu [...]

Carotenoid cleavage dioxygenase 8, chloroplastic; Involved in strigolactones biosynthesis by cleaving the C(27) 9-cis-10'-apo-beta-carotenal produced by CCD7. Produces the C(19) carlactone and a C(8) hydroxyaldehyde. Also shows lower activity with all-trans-10'-apo-beta-carotenal producing a C(9) dialdehyde and the C(18) 13-apo-beta-carotenone. Strigolactones are hormones that inhibit tillering and shoot branching through the MAX-dependent pathway, contribute to the regulation of shoot architectural response to phosphate-limiting conditions and function as rhizosphere signal that stimu [...]

ATP-dependent Clp protease adapter protein CLPS1, chloroplastic; Small adapter protein that modulate the activity of CLPC (By similarity). Involved in plastid biogenesis in particular when chloroplast protein synthesis capacity is a limiting factor. Probably involved in substrate selection for plastid Clp protease system. Recruitment to ClpC chaperones is facilitated by CLPF thus forming a binary adapter for selective substrate recognition and delivery to plastid Clp protease system (CLPC).

Protein RADIALIS-like 5; Probable transcription factor.

Squamosa promoter-binding-like protein 15; Trans-acting factor that binds specifically to the consensus nucleotide sequence 5'-TNCGTACAA-3'.
