The role of proline in osmoregulation in Phytophthora nicotianae

Ambikapathy, Jesmini; Marshall, Jerry S; Hocart, Charles H; Hardham, Adrienne R

Description

A cDNA encoding Δ¹-pyrroline-5-carboxylate reductase (P5CR), the enzyme that catalyzes the final step in proline biosynthesis in plants and bacteria, has been cloned from the oomycete plant pathogen Phytophthora nicotianae. Genomic DNA blots indicated that P. nicotianae and P. cinnamomi each contain a single P5CR gene, whereas P. infestans contains one or two genes. Complementation of a strain of Escherichia coli defective in the P5CR protein by the P. nicotianae P5CR cDNA confirmed that the...[Show more]
