Title: Preliminary analysis of endogenous pectins and arabiongalactan proteins during ovule embriognesis in sugar beet (Beta vulgaris L.)
Biography: Sandra K. Cichorz
The production of haploid and doubled haploid plants (DH) is now recognized as the most convenient method to produce homozygous lines. As opposed to conventional inbreeding, which requires several cycles of self-pollination, in vitro cultures enables greatly time reduction during breeding process. Over the last decades, advances in sugar beet (Beta vulgaris L.) doubled haploid production have been achieved. Numerous endogenous and exogenous factors, which affect the embryo genic response of gametes in culture have been described and improved. But still, ovule embryogenesis efficiency in this species varies between 1 and 15%. The arabinogalactan proteins (AGP) and pectins have proved to pay many important roles in the reproductive processes or differentiation and development of plant cells and tissues. As cell wall structural proteins, are one of the most widespread protein family in the plant kingdom. Based on this, we combine our own latest results describing the characterization of AGP and pectin extracts from unfertilized ovules from sugar beet genotypes of different embryogenic potential with the current achievements.
