Transcriptional regulation of anther development in Arabidopsis.

This review focuses on the current knowledge of transcription factors involved in Arabidopsis anther development. Anther development is a multistage process and controlled by a complex network of transcription factors acting in spatio/temporal manner. Molecular understanding of anther developmental pathway is critical from the perspective of controlling male fertility and hybrid generation. Generation of hybrid lines relies upon the effective mechanisms of controlling the process of pollen development and pollen release. Controlling any developmental program requires a good knowledge of regulatory pathways governing that developmental program. In a regulatory pathway, transcription factors represent an important link between the developmental program and response of genes to growth regulators and environmental signals. Therefore, identifying the entire cohort of anther specific transcription factors is an essential step towards the molecular understanding of regulatory networks involved in pollen formation and pollen release.
