X At1g01280 839470 CYP703A2 (CYTOCHROME P450, FAMILY 703, SUBFAMILY A, POLYPEPTIDE 2) member of CYP703A CYP703A2 is expressed specifically in anthers of land plants, catalyzing the in-chain hydroxylation at the C-7 position of medium-chain saturated fatty acids (lauric acid in-chain hydroxylase) which is involved in pollen development (sporopollenin synthesis). O.I. H.G.
X At1g02050 839280 chalcone and stilbene synthase family protein F:transferase activity, transferring acyl groups other than amino-acyl groups, catalytic activity, acyltransferase activity;P:phenylpropanoid biosynthetic process, pollen exine formation;C:unknown;PBOF O.I. H.G.
X At1g33430 840236 galactosyltransferase family protein F:transferase activity, transferring hexosyl groups, transferase activity, transferring glycosyl groups;P:pollen exine formation;C:endomembrane system, membrane;MPO O.I. H.G.
X At1g62940 842596 ACOS5 (ACYL-COA SYNTHETASE 5) encodes an acyl-CoA synthetase, has in vitro activity towards medium- to long-chain fatty acids and their hydroxylated derivatives. Expressed in the tapetum. Involved in pollen wall exine formation. Null mutants were devoid of pollen grains at anther maturity and were completely male sterile. O.I. H.G.
X At1g65060 842814 4CL3 encodes an isoform of 4-coumarate:CoA ligase (4CL), which is involved in the last step of the general phenylpropanoid pathway. mRNA levels are not induced in response to wounding or to fungal infection by P. parasitica. mRNA is expressed in flowers, to a lesser degree in mature leaves and siliques and marginally in seedling roots and bolting stems of mature plants. The catalytic efficiency was in the following (descending) order: p-coumaric acid, caffeic acid, ferulic acid, cinnamic acid and 5-OH-ferulic acid. At4CL3 was unable to use sinapic acid as substrate.

X At4g20050 827750 QRT3 (QUARTET 3) Encodes a polygalacturonase that plays a direct role in degrading the pollen mother cell wall during microspore development. O.I. H.G.
