Papaya breeding for PRV resistance

, : Papaya breeding for PRV resistance. Acta Horticulturae ( 370): 27-31

Moderate genetic resistance to papaya ringspot potyvirus (PRV) in pawpaw germplasm was used in conventional breeding programmes in Florida and Hawaii, USA, to create PRV-tolerant cultivars that are a compromise between useful resistance and acceptable fruit quality. In Hawaii, phenotypic recurrent selection and RAPD marker assisted selection were used to improve fruit quality and PRV resistance in populations derived from crossing a virus-tolerant parent with commercial cultivars.

The E-cadherin-mediated cell adhesion system is now considered to be an "invasion suppressor system" in cancer cells. Dysfunction of the E-cadherin system due to mutations of the genes of E-cadherin and catenins has not been reported in...

Near-field scanning optical microscopy (NSOM) uses the near-field interaction of light from a sharp fiber-optic probe with a sample of interest to image surfaces at a resolution beyond the diffraction limit of conventional optics. We used NSOM to...

Purpose: To study the association between Alzheimer's disease (AD) and plasma total homocysteine (tHcy), dietary folate and vitamin B6. Methods: 64 AD patients, in Cleveland, Ohio, USA were matched by gender, age, and smoking status to 64 hea...

The signal peptide coding regions of P.II genes contain variable numbers of tandem repeats...

The impact of growth restriction on perinatal morbidity is well known, but electroencephalographic (EEG) data on its influence are still scarce. We aimed to analyze the influence of being born small for gestational age (SGA; defined as a birth wei...
