Résumé / Abstract

Gametophyte development is a highly coordinated process that requires interactions between sporophytic and gametophytic tissues in reproductive structures. Male gametophyte development occurs in anthers and proceeds through a series of well-defined developmental stages. Disruption of normal anther development often results in male sterility (i.e., the inability to produce functional pollen). Male sterility has been widely studied in response to both its biological significance and commercial use in hybrid seed production. These studies have led to the identification of numerous male sterile mutants that can be classified into two groups based on their pattern of inheritance. Genic male sterility results when lesions in nuclear-encoded genes disrupt normal anther development; over 40 genic male sterility loci affecting nearly all stages of development have been identified. Cytoplasmic male sterility (cms) is a maternally inherited inability to produce viable pollen that is associated with novel mitochondrial open reading frames (mtORFs). In maize, three major types of cms, which can be distinguished by molecular markers and the nuclear-encoded restorer genes that overcome the deleterious effects of the mtORF, have been identified. Significant progress has been made in understanding the fundamental basis of male sterility over the past 80 years. In this review recent developments in male sterility research are discussed with particular emphasis on genetic defects and molecular and cytological characterizations.
