Gene Details:

• Gene ID: Zm00001eb305800
• Gene Symbol: ZmPKSB chls1
• Gene Name: chalcone synthase1
• Genome: Zm-B73-REFERENCE-NAM-5.0
• Species: Zea mays

Functional Descriptions:

• The causal gene (ZmPKSB) of pksb mutant encoded an endoplasmic reticulum (ER)-localized polyketide synthase (PKS) with catalytic activities to malonyl-CoA and midchain-fatty acyl-CoA to generate triketide and tetraketide α-pyrone.
• The ZmMYB84-ZmPKSB regulatory module controlled a trade-off between anther cuticle and pollen exine formation by altering expression of a series of genes related to biosynthesis and transport of sporopollenin.
• ZmPKSB functions as a polyketide synthase with its enzymatic activities dependent on a catalytic triad.
• ZmPKSB is an active polyketide synthase with its enzymatic activities dependent on a catalytic triad and can use fatty acyl-CoA esters as starter substrates to produce triketide and tetraketide α-pyrone.
• The ZmMYB84-ZmPKSB regulatory module controlled a trade-off between anther cuticle and pollen exine formation by altering expression of a series of genes related to biosynthesis and transport of sporopollenin, cutin and wax.
