Arabidopsis	At1g01280	Involved in pollen wall development.	CYP703 is an ancient cytochrome P450 in land plants catalyzing in-chain hydroxylation of lauric acid to provide building blocks for sporopollenin synthesis in pollen.; 2007; DOI: 10.1105/tpc.106.045948; PMID: 17496121; https://pubmed.ncbi.nlm.nih.gov/17496121/
Rice	Os08g0131100	Involved in pollen exine and anther epicuticular layer development.	Rice CYP703A3, a cytochrome P450 hydroxylase, is essential for development of anther cuticle and pollen exine.; 2014; DOI: 10.1111/jipb.12212; PMID: 24798002; https://pubmed.ncbi.nlm.nih.gov/24798002/
