主 题：sporopollenin pollen cell wall phenylpropanoid pathway
摘 要：The outer wall of pollen and spores,namely the exine,is composed of sporopollenin,which is highly resistant to chemical reagents and *** this study,we demonstrated that phenylpropanoid pathway derivatives are essential components of sporopollenin in seed *** analyses showed that the autofluorescence of Lilium and Arabidopsis sporopollenin is similar to that of *** and NMR analyses of pollen from Lilium and Cryptomeria further revealed that the sporopollenin of seed plants contains phenylpropanoid derivatives,including p-hydroxybenzoate(p-BA),p-coumarate(p-CA),ferulate(FA),and lignin guaiacyl(G)*** phenylpropanoid pathway is expressed in the tapetum in Arabidopsis,consistent with the fact that the sporopollenin precursor originates from the *** germination and comet assays showed that this pathway plays an important role in protection of pollen against UV *** the pteridophyte plant species Ophioglossum vulgatum and Lycopodium clavata,phenylpropanoid derivatives including p-BA and p-CA were also detected,but G units were *** together,our results indicate that phenylpropanoid derivatives are essential for sporopollenin synthesis in vascular *** addition,sporopollenin autofluorescence spectra of bryophytes,such as Physcomitrella and Haplocladium,exhibit distinct characteristics compared with those of vascular plants,indicating the diversity of sporopollenin among land plants.
