Transcription factor AtMYB103 is required for anther development by regulating tapetum development, callose dissolution and exine formation in Arabidopsis.
Downregulation of the transcription factor AtMYB103 using transgenic technology results in early tapetal degeneration and pollen aberration during anther development in Arabidopsis thaliana. This paper describes the functional analysis of the AtMYB103 gene in three knock-out mutants. Two male sterile mutants, ms188-1 and ms188-2, were generated by ethyl-methane sulfonate (EMS) mutagenesis. A ma...
متن کاملSpecification of tapetum and microsporocyte cells within the anther.
Flowering plants form male reproductive cells (microsporocytes) during sporophytic generation, which subsequently differentiate into multicellular male gametes in the gametophytic generation. The tapetum is a somatic helper tissue neighboring microsporocytes and supporting gametogenesis. The mechanism controlling the specification of the tapetum and microsporocyte cell fate within the anther ha...

متن کاملSilencing of the tapetum-specific zinc finger gene TAZ1 causes premature degeneration of tapetum and pollen abortion in petunia.
TAZ1 (TAPETUM DEVELOPMENT ZINC FINGER PROTEIN1; renamed from PEThy; ZPT3-2) cDNA was first isolated as an anther-specific cDNA from petunia. Here, we report a functional characterization that includes analysis of spatial and temporal expression profiles and examination of anther phenotypes in TAZ1-silenced plants. TAZ1 showed a biphasic expression pattern. In the premeiotic phase, TAZ1 transcri...
متن کاملHistone H2B Monoubiquitination Mediated by HISTONE MONOUBIQUITINATION1 and HISTONE MONOUBIQUITINATION2 Is Involved in Anther Development by Regulating Tapetum Degradation-Related Genes in Rice.
Histone H2B monoubiquitination (H2Bub1) is an important regulatory mechanism in eukaryotic gene transcription and is essential for normal plant development. However, the function of H2Bub1 in reproductive development remains elusive. Here, we report rice (Oryza sativa) HISTONE MONOUBIQUITINATION1 (OsHUB1) and OsHUB2, the homologs of Arabidopsis (Arabidopsis thaliana) HUB1 and HUB2 proteins, whi...
