[Genetical effect of different rye chromosomes on the acid phosphatase (Acph) secretion of common wheat roots under phosphorus starvation conditions].
The effects of different rye chromosomes on Acph secretion of common wheat roots under P starvation conditions were studied by using a set of Chinese Spring-Imperial (CS-IMP) alien addition lines as materials. The Acph activity measurement results showed that P starvation is an induction factor for Acph gene expression; Different chromosomes of Imperial rye in Chinese Spring background has different effects on the secretion of Acph by corresponding addition line roots. Among them, chromosome 1R had the strongest promoting effect; The IEF diagram of Acph isozymes clearly demonstrated that chromosome 1R in rye genome carries P starvation inducible Acph gene(s).
