The change in developmental fate of microspores reprogrammed toward embryogenesis is a complex but fascinating experimental system where microspores undergo dramatic changes derived from the developmental switch. After 40 years of study of the ultrastructural changes undergone by the induced microspores, many questions are still open. In this work, we analyzed the architecture of DNA-containing...
In Arabidopsis thaliana, zygotic embryo divisions are highly regular, but it is not clear how embryo patterning is established in species or culture systems with irregular cell divisions. We investigated this using the Brassica napus microspore embryogenesis system, where the male gametophyte is reprogrammed in vitro to form haploid embryos in the absence of exogenous growth regulators. Microsp...
Abstract The Balkan pepper breeding program aims to use in vitro embryogenesis (anther culture) develop doubled haploid lines with valuable traits. We analyzed the effectiveness of microspore on 17 genotypes comprised varieties, lines, and F 1 hybrids different varietal types (conical, bell shape, kapia) characterized agronomic traits newly generated lines. highest androgenic potential was obse...
