Abstract
Peroxidase and esterase isozymes were investigated during plant regeneration via somatic embryogenesis in Bambusa vulgaris, The transition of non-embryogenic calli to embryogenic calli, somatic embryo development, germination and subsequent flowering of somatic embryo derived shoots were associated with selective expression or repression of isoforms of peroxidase and esterase. Non-embryogenic callus showed six peroxidase and four esterase bands. During somatic embryogenesis and germination of somatic embryos, some bands were suppressed and new isoforms of peroxidase and esterase appeared. During flowering, in addition to four peroxidase bands, a new unique esterase band ‘a’ appeared. Each developmental stage was thus associated with a definite isozyme profile.
