Papaya is a major fruit crop in the tropics and has recently evolved sex chromosomes. Towards sequencing the papaya sex chromosomes, two bacterial artificial chromosome (BAC) libraries were constructed from papaya male and female genomic DNA. The female BAC library was constructed using restriction enzyme BstY I and consists of 36,864 clones with an average insert size of 104 kb, providing 10.3...

In order to prepare pure enzyme before gene cloning the proteins were separated by fast protein liquid chromatography and used to prepare monoclonal antibodies to papaya proteinase A and B. Crude spray-dried latex from Powell and Scholefield was dialysed against 1,3-diaminopropane and the enzyme isolated by the method of Goodenough & Owen (1986) using 6 mM-diaminopropane as buffer and a gradien...

debaryomyces hansenizopf isolated from the fructoplane of apples were found to be effective as biocontrol agent against rot of papaya caused by ulocladium. chartarum(pr.) simm. the ability of d. hansenii to prevent infection of u. chartarum was lost when the antagonist cells were killed by autoclaving. cell free culture filtrates of antagonist were unable to prevent disease incidence. efficacy ...

The aim of present study is to investigate neuroprotective and nootropic activity of Petroleum Ether Extract of Carica papaya seeds (PEECPS) on diabetic induced cognitive decline rats. Rectangular maze and morris water maze models were used to evaluate nootropic activity and neuroprotective effects were studied by estimating acetyl cholinesterase (AchE), malondialdehyde (MDA), superoxide dismut...

background: the aims of the study are to determine the radioactivity concentrations of 226ra, 238u, 232th and 40k in vegetables of a recently found high background radiation area of south-eastern part of bangladesh and to detect the radiological risks to human from intake of these vegetables. materials and method: 10 plant samples were collected randomly from different locations of the study ar...

Previous studies have shown favourable properties for papaya bast fibres, with a Young's modulus of up to 10 GPa and a tensile strength of up to 100 MPa. Because the fibres remain as residues on papaya plantations across the tropics in large quantities, their use in the making of green composites would seem to be worthy of consideration. This study aims to show that such composites can have ver...

Studies were carried out to natural papain inhibitor from papaya latex. Fresh latex from green fruits of Carica papaya was collected and immediately transported in ice bath to the lab, from which three fractions with inhibitor effect of esterase papain activity were isolated by latex dialysis, Sephadex G-25 gel filtration and ionic exchange chromatography in SP-Sephadex C-25. The isolated fract...

Using molecular data, we recently showed that Carica papaya L. is sister to a Mexican/Guatemalan clade of two genera, Jarilla Rusby with three species and Horovitzia V.M. Badillo with one. These species are herbs or thin-stemmed trees and may be of interest for future genomics-enabled papaya breeding. Here we clarify the correct names of Jarilla heterophylla (Cerv. ex La Llave) Rusby and Jarill...

The present study was conducted to evaluate the antioxidant and immunostimulant effects of The Carica papaya fruit aqueous extract (CPF, Caricaceae) against acrylamide induced oxidative stress and improvement of Immune functions which affected by free radicals liberating acrylamide in rats. Sixty male wistar albino rats (195 – 230 g) were assigned to four groups, (fifteen/group). The first grou...
