C-3 Epimerization of 6-Deoxocastasterone in Phaseolus vulgaris

摘要

Brassinosteroids (BRs) are steroidal plant hormones,which exert a variety of regulatory effects relevant to plant growth and development.Thus far,over 40 different BRs have been identified throughout the entirety of the plant kingdom.Among the plants so far tested for their BR contents,the immature seeds of Phaseolus vulgaris represent one of the richest.11 BRs have been fully characterized from this source,whereas the presence of more than 60 additional unknown BRs has been demonstrated via capillary GC-MS analyses.
