Arabidopsis SOMATIC EMBRYOGENESIS RECEPTOR KINASES1 and 2 are essential for tapetum development and microspore maturation.
Among the >200 members of the leucine-rich repeat receptor kinase family in Arabidopsis thaliana, only a few have been functionally characterized. Here, we report a critical function in anther development for the SOMATIC EMBRYOGENESIS RECEPTOR KINASE1 (SERK1) and SERK2 genes. Both SERK1 and SERK2 are expressed widely in locules until stage 6 anthers and are more concentrated in the tapetal cell...

متن کاملDefective in Tapetal development and function 1 is essential for anther development and tapetal function for microspore maturation in Arabidopsis.
In Arabidopsis, the tapetum plays important roles in anther development by providing enzymes for callose dissolution and materials for pollen-wall formation, and by supplying nutrients for pollen development. Here, we report the identification and characterization of a male-sterile mutant, defective in tapetal development and function 1 (tdf1), that exhibits irregular division and dysfunction o...
متن کاملPectic arabinan side chains are essential for pollen cell wall integrity during pollen development.
Pectin is a complex polysaccharide and an integral part of the primary plant cell wall and middle lamella, contributing to cell wall mechanical strength and cell adhesion. To understand the structure-function relationships of pectin in the cell wall, a set of transgenic potato lines with altered pectin composition was analysed. The expression of genes encoding enzymes involved in pectin acetyla...
متن کاملExpression and localization of two anther-specific genes in the tapetum and microspore of Lilium longiflorum
Two stage-specific genes have been isolated from a subtractive cDNA library constructed from developing anthers of Lilium longiflorum. Tandem 5ˊand 3ˊ-rapid amplifications of cDNA ends with polymerase chain reaction (5ˊand 3ˊ-RACE-PCR) were used to obtain the full length cDNA sequences. The LLA89 cDNA contained an open reading frame of 303 bp encoding an acidic polypeptide of 100 amino acids wi...
