A CDNA FROM PEA PETALS WITH SEQUENCE SIMILARITY TO POLLEN ALLERGEN, CYTOKININ-INDUCED AND GENETIC TUMOUR-SPECIFIC GENES - IDENTIFICATION OF A NEW FAMILY OF RELATED SEQUENCES

摘要

A cDNA isolated from pea petals exhibits extensive similarity to pollen allergen genes, a cytokinin-regulated cDNA from soybean suspension cultures, a partial cDNA preferentially expressed in tobacco genetic tumours, four Arabidopsis expressed sequence tags (ESTs) and fifteen rice ESTs. This diverse family of pollen allergen-likes genes may have a common ancestor or at least share common functional domains. Possession of a putative signal peptide and a presumed extracellular location is a common aspect of this family of sequences. [References: 20]
