1 The fatty acyl-CoA esters synthesized by Arabidopsis thaliana ACYL-COA SYNTHETASE5 (ACOS5) are key intermediates in the biosynthesis of sporopollenin, the major constituent of exine in the outer pollen wall. sporopollenin acyl-CoA synthetase 5 Arabidopsis thaliana
2 The fatty acyl-CoA esters synthesized by Arabidopsis thaliana ACYL-COA SYNTHETASE5 (ACOS5) are key intermediates in the biosynthesis of sporopollenin, the major constituent of exine in the outer pollen wall. sporopollenin acyl-CoA synthetase 5 Arabidopsis thaliana
3 These results show that hydroxylated alpha-pyrone polyketide compounds generated by the sequential action of ACOS5 and PKSA/B are potential and previously unknown sporopollenin precursors. sporopollenin acyl-CoA synthetase 5 Arabidopsis thaliana
