RESUMO
Efforts have been made in recent years to clarify molecular meiotic processes in a large variety of higher eukaryotes. In plants, such studies have enjoyed a boom in the last years with the use of Arabidopsis thaliana together with maize, rice and tomato as model systems. Owing to direct and reverse genetic screens, an increasing number of genes involved in meiosis have been characterized in plants. In parallel, the improvement of cytological and genetical tools has allowed a precise description of meiotic recombination events. Thus, it appears that meiotic studies in plants are reaching a new stage and can provide new insights into meiotic recombination mechanisms. In this review, we intend to give an overview of these recent advances in the understanding of meiotic recombination in plants.
