Our previous data suggested that the a , p 3 integrin-like proteins be present in lily pollen tube and mediate the interaction between pollen and extracellular matrix of pistil to regulate pollen tube growth. To elucidate further the presense and function of integrin-like protein ,we try to clone 3' terminus seqence of integrin-like gene from germinated pollen of lily by 3' RACE using degenerate primers corresponding to the conserved cytoplasmic regions of a and 3 subunits. However, it proved fr...
