Dobzhansky, Carol Madden, and to Mr. B. A. Spassky for their efficient help in carrying out the very laborious experiments and calculations. Professor Howard Levene and Mr. Timothy Prout have contributed some valuable advice concerning statistical problems. We wish also to acknowledge stimulating disoussion's with Professor I. Michael Lerner, who has dealt with the problem of "genetic homeostas...

Prunus necrotic ringspot virus (PNRSV) and cherry A (CVA) are two viruses that mainly infect plants of the genus Prunus. Full-length sequences these viruses, collected in Czech Republic from cerasifera plants, were obtained via HTS sequencing. Phylogenetic analyses based on NJ method Splitstree tools showed PNRSV isolate (ON088600-ON088602) is a divergent other molecular groups, sharing less th...

This work describes, for the first time, the changes taking place in the antioxidative system of the leaf apoplast in response to plum pox virus (PPV) in different Prunus species showing different susceptibilities to PPV. The presence of p-hydroxymercuribenzoic acid (pHMB)-sensitive ascorbate peroxidase (APX) (class I APX) and pHMB-insensitive APX (class III APX), superoxide dismutase (SOD), pe...

A nondestructive optical method for determining the total solids content (TSC) and soluble solids content (SSC) of fresh whole prune (Prunus domestica L. ‘French’) was investigated. The method, based upon near infrared spectrophotometric techniques, could predict the TSC (r /0. 98, SEP /0.80% FW) and SSC (r /0. 96, SEP / 1.02%) of prunes. A low cost ($250
