    Spolupráce s CIMMYT při studiu diverzity a evoluce B chromozomu kukuřice

  • Annotation in Czech

    Cílem tohoto projektu je analýza diverzity B chromozomů v rámci kukuřice seté (Zea mays). Pomocí molekulárních, molekulárně-cytogenetických a sekvenačních přístupů budou získána data, která zásadní měrou přispějí k poznání genových i repetitivních oblastí B chromozomu kukuřice a jeho evoluce. Nedílnou součástí projektu je i charakterizace fenotypu studovaných rostlin s B chromozomy.

  • Project results evaluation

    New insights into diversity of the maize B chromosome were gained. Markers were developed for the B chromosome and a list of B-positive accessions was created. Sequence of 100 lines carrying the B chromosome was obtained and the existence of two evolutionary branches of the chromosome was demonstrated. Furthermore, protocol to determine number of B chromosomes was developed and effect of the B chromosome on gene expression in different parts of the plant was described.
