354 Development of Off-flavor in Melting Flesh and Nonmelting Flesh Peach Genotypes

Changes in endopolygalacturonase levels and characterization of a putative endo-PG gene during fruit softening in peach genotypes with nonmelting and melting flesh fruit phenotypes.

The changes in endopolygalacturonase (endo-PG) levels and endo-PG expression in nonmelting flesh (NMF) and melting flesh (MF) peach fruits (Prunus persica) during softening were studied. The endo-PG gene was analysed to identify polymorphisms exploitable for early marker-assisted selection (MAS) of flesh texture. The role of endo-PG in softening was assessed by western and northern blotting and...

Peach (Prunus persica) endopolygalacturonase cDNA isolation and mRNA analysis in melting and nonmelting peach cultivars.

Two distinct partial cDNAs, PRF1 and PRF3, similar in sequence to previously described polygalacturonases, were amplified from ripe peach (Prunus persica L. Batsch cv Flavorcrest) fruit cDNA by the polymerase chain reaction. PRF1-related RNA was present in fruit from early ripening at levels not detected by northern analysis. PRF3-related RNA was readily detectable in ripe fruit by northern ana...

Sex in the flesh.

This response to Michael Stolberg argues that the occasional piece of evidence for sexual dimorphism in Renaissance anatomy does no damage to what I had earlier called the "one-sex model." There are three reasons for this: a considerable amount of such evidence had long been available; stray observations do not discredit worldviews; and new supporting evidence for the one-sex model was also ava...
