Endogenous auxin accumulation/localization during zygotic and somatic embryogenesis of Capsicum chinense Jacq.

Zygotic and somatic embryogenesis in plants is a fascinating event that is finely regulated through the expression of a specific group of genes and dynamic levels of plant hormones whose concerted action determines the fate that specific cells follow towards zygotic or somatic embryo development. This work studied different stages of Capsicum chinense Jacq. zygotic and somatic embryogenesis.

Genes involved in the deformations of the shoot apical meristem in somatic embryos of Jacq.

Somatic embryos (SE) of habanero pepper ( Jacq.) represent persistent deformations in the shoot apical meristem (SAM), which inhibits their capacity to form organs and subsequently plants. In dicotyledonous plants, SAM is formed in the apex, between cotyledons and it plays a central role in postembryonic shoot organ formation.

Development of the ovule and seed of Habanero chili pepper (Capsicum chinense Jacq.): Anatomical characterization and immunocytochemical patterns of pectin methyl-esterification.

Ovule and seed development in plants has long fascinated the scientific community given the complex cell coordination implicated in these processes. These cell events are highly conserved but are not necessarily representative of all plants. In this study, with the aim of obtaining information regarding the cellular patterns that follow the usual development of the ovule and the zygotic embryo, we carried out an integral anatomical study of the Capsicum chinense Jacq.
