Abstract:
... Papaya (Carica papaya) is a very important crop in many tropical countries but it is highly susceptible to parasitic diseases, physiological disorders, mechanical damage and fruit overripening. Here we report a study on ACC oxidase cosuppression and its effects on papaya fruit ripening. Papaya ACC oxidase was isolated using PCR and embriogenic cells transformed by biolistic using the CaMV 35S prom ...

Abstract:
... Due to their flavor and nutritional characteristics, papaya fruit are consumed worldwide. As a tropical commodity, storage has serious limitations that result in their rapid deterioration and high incidence of rots during handling and storage. Postharvest handling of papaya differs according to destination. For export markets, there are well-defined postharvest steps established that include techn ...

DNA primers; Pleurotus djamor; genetic improvement; genetic variation; germplasm conservation; hybrids; internal transcribed spacers; microsatellite repeats; mushroom growing; Mexico
Abstract:
... Molecular characterisation of wild type Pleurotus species is important for germplasm conservation and its further use for genetic improvement. No molecular studies have been performed with monokaryons used for producing hybrid strains, either with the reconstituted strains obtained by pairing those monokaryons. The molecular characterisation of parental dikaryons, hybrid, and reconstituted strains ...

Abstract:
... Pleurotus ostreatus is an edible mushroom with significant nutritional properties and highly valuable protein concentrates can be obtained from its fruit bodies. Functional properties of flours and protein concentrates derived from 3 Pleurotus ostreatus strains (PCM, POS and hybrid PCM × POS) were evaluated in this investigation. Fruit bodies were produced on wheat straw substrate, flours were obt ...

Abstract:
... Pectobacterium carotovorum was incubated in formulations of chitosan nanoparticles or thyme essential oil-loaded chitosan nanoparticles for a maximum period of 48 h time. The cellular changes and viability were evaluated by transmission electron microscopy (TEM), and two colorimetric assays 3-(4,5 dimethylthiazol-2-yl)-2,5diphenyl tetrazolium bromide (MTT) and alamar blue (AMB), respectively. The ...
