摘要
Most angiosperm actin genes, including the pollen-specific tobacco actin gene Tac25, contain three introns at conserved locations within their protein coding region. We have isolated one tomato and two potato actin genes that are related to this pollen-specific tobacco actin gene and which have lost one or two introns. The loss of these introns was likely the result of at least two gene conversion events with cDNAs derived from transcripts of pollen-specific genes.
