Genetics of meiotic prophase I in plants

Abstract

During meiotic prophase I, traits are reassorted as a result of a highly organized process involving sister chromatid cohesion, homologous chromosome alignment, pairing, synapsis, and recombination. In the past two years, a number of components involved in this pathway, including Structure Maintenance of Chromosomes (SMC), MRE11, the RAD51 homologs, BRCA2, MSH4, MER3, and ZIP1, have been characterized in plants; in addition, several genes that encode components unique to plants, such as POOR HOMOLOGOUS SYNAPSIS 1 and AMEIOTIC 1, have been cloned. Based on these recent data, essentially from maize and Arabidopsis, we discuss the conserved and plant-specific aspects of meiosis commitment and meiotic prophase I features.
