The Development of Microbodies (Glyoxysomes and Leaf Peroxisomes) in Cotyledons of Germinating Watermelon Seedlings 1

AUTOR(ES)
RESUMO

The ontogeny of glyoxysomes and leaf peroxisomes has been examined in the cotyledons of germinating watermelon (Citrullus vulgaris) seedlings. Organelles from the cotyledons were extracted by razor blade homogenization and microbodies were separated by sucrose density gradient fractionation. Both kinds of microbodies have the same mean equilibrium density on sucrose gradients.
