|Abstract: ||To identify genes that play an important gametophytic role during pollen development, an Arabidopsis transposon (DsE) mutagenised population was screened for marker segregation ratio distortion. We report the characterisation of a male gametophytic mutant termed halfman (ham) that results in an aborted pollen phenotype in mature anthers. The genetic transmission efficiency of DsE was 6.6% through the male and 98.4% through the female, which suggested that HAM may encode essential male-specific component(s) required for pollen development. Molecular analysis of the insertion site revealed a single copy of the DsE element inserted into the second exon of the RLK5 gene that was adjacent to a large (~150 Kb) genomic deletion. The deleted region is predicted to encode 38 genes and to include one or more genes with important function(s) during pollen maturation and seed development.|
