Changes in ABA, IAA and JA levels during calyx, fruit and leaves development in cape gooseberry plants (Physalis peruviana L.).

Changes in abscisic acid (ABA), indole-3-acetic acid (IAA) and jasmonic acid (JA) content in developing calyx, fruits and leaves of Physalis peruviana L. plants were analysed. Plant hormones have been widely studied for their roles in the regulation of various aspects related to plant development and, in particular, into their action during development and ripening of fleshly fruits. The obtained evidences suggest that the functions of these hormones are no restricted to a particular development stage, and more than one hormone is involved in controlling various aspects of plant development. Our results will contribute to understand the role of these hormones during growth and development of calyx, fruits and leaves in cape gooseberry plants. This work offers a good, quickly and efficiently protocol to extract and quantify simultaneously ABA, IAA and JA in different tissues of cape gooseberry plants.

Immunolocalization of the lectins P2 and P4 from Dioclea lehmanni seeds.

Intracellular localization of the lectins P2 and P4 from Dioclea lehmanni in developing cotyledons and in mature embryo axis were analyzed by the immunogold method. In parenchyma cells of the mature cotyledons both lectins were found in the protein bodies, whereas in immature cotyledons and in mature embryo axis these lectins were exclusively localized in the vacuoles.
