S-RNase-based gametophytic self-incompatibility (GSI) has evolved once before the split of the Asteridae and Rosidae. This conclusion is based on the phylogenetic history of the S-RNase that determines pistil specificity. In Rosaceae, molecular characterizations of Prunus species, and species from the tribe Pyreae (i.e., Malus, Pyrus, Sorbus) revealed different numbers of genes determining S-po...

The red color of fruit is an attractive plant trait for consumers. Plants with color-faded fruit have a lower commercial value, such as 'Red Bartlett' pears (Pyrus communis L.) that have dark-red fruit in the early stages of fruit development that subsequently fade to red-green at maturity. To identify the reason for color fading, we first analyzed the anthocyanin content of peel from 'Red Bart...

Plants have the capability to produce an extensive variety of chemical compounds that in turn exert important biological functions and modify different pathological conditions in both human and animals. In this way medicinal plants mediate their effects through Chemical compounds and these processes are identical to those already well understood for the chemical compounds in conventional drugs....

Volatiles are essential substances that determine distinct fruit flavors and user preferences. However, the metabolic dynamic molecular modulation models regulate overall flavor generation during growth ripening still largely unclear for most species. To comprehensively analyze mechanism regulation of aroma accumulation component formation in Pyrus spp. ‘Panguxiang’ (‘Panguxiang’pear), this stu...

Black stain is a postharvest disease that occurs on the skin of Niitaka pears (Pyrus pyrifolia Nakai) during cold storage, causing significant economic losses to pear production. We investigated antifungal effects peracetic acid (PAA), which strong oxidizing agent and an effective disinfectant, fungi cause black stain, we confirmed its preventive effect after application pears. Fungal isolates ...

Lignin is one of the main components plant cell walls, which provides mechanical support for plants and also contributes to resisting against pathogenic fungi. In fruit industry, lignin content can affect quality fruit. The biosynthesis involves a variety enzymes, caffeoyl-CoA 3-O-methyltransferase ( CCoAOMT ) class methyltransferases that plays an essential role in biosynthesis. Studies have b...
