Papaya (Carica papaya L.) is a fleshy fruit that presents a rapid pulp softening during ripening. However, the timeline on how papaya pectinases act in polysaccharide solubilization and the consequent modification of the cell wall fractions during ripening is still not clear. In this work, the gene expression correlations between, on one hand, 16 enzymes potentially acting during papaya cell wa...

The present study was under taken to establish the uterine stimulant activity of aqueous extract of unripe Carica papaya. The effect of the aqueous extract of unripe Carica papaya was studied on isolated rat uterus and embryo. Uterine stimulant activity was compared with clinically available drug oxytocin and the effect on embryo was compared with misoprostol. In the in vitro model, Carica papa...

Auxin plays essential roles in plant development. Gretchen Hagen 3 (GH3) genes belong to a major auxin response gene family and GH3 proteins conjugate a range of acylsubstrates to alter the levels of hormones. Currently, the role of GH3 genes in postharvest physiological regulation of ripening and softening processes in papaya fruit is unclear. In this study, we identified seven CpGH3 genes in ...

Papaya (Carica papaya) is an important fruit grown almost throughout Bangladesh. The study was conducted to determine the physico-chemical characteristics of 20 papaya germplasms and to develop products (jam and squash) from papaya available in the south western regions of Bangladesh. The experiment was laid out in the completely randomized design (CRD) with three replications. Papaya fruits we...

Shortly after its introduction into the Hawaiian Islands around 1895, the polyphagous, invasive fruit fly Bactrocera (Zeugodacus) cucurbitae (Coquillett) (Diptera: Tephritidae) was provided the opportunity to expand its host range to include a novel host, papaya (Carica papaya). It has been documented that female B. cucurbitae rely strongly on vision to locate host fruit. Given that the papaya ...

Papaya meleira virus (PMeV) is the causal agent of papaya (Carica papaya L.) sticky disease, which has been detected through analysis of its double-stranded RNA (dsRNA) genome from plant latex. In this work we demonstrate that PMeV dsRNA is protected during 25 days when latex is diluted in citrate buffer pH 5.0 (1:1 v/v) and maintained at -20ºC. At the same temperature, some protection was obse...

An experiment was carried out to investigate the anthelmintic activity of papaya latex (Carica papaya) against natural infection of Ascaris suum in pigs. Sixteen naturally infected pigs were, on the basis of faecal egg counts and body weight, allocated into four groups, each of four pigs. Three groups (groups B, C, and D) were given papaya latex per os at dose levels of 2, 4, and 8 g of papaya ...

The use of dietary antioxidants and nutraceuticals is one of the strategies often pursued as low cost remedies to reduce oxidative stress for preventing diabetes and its chronic complications [2]. Different parts of papaya (seeds, roots, leaves, barks, flowers, latex, and fruit) have been used in folk medicine to treat various diseases, including diabetes, cancer, and cardiovascular and infecti...

Hemicycliophora ritteri and Paratrichodorus minor were associated in high numbers with a previously unknown "dieback disease" of cranberry. Chemical treatment with nematicides and fungicides failed to control this disease. There were no correlations (P </= 0.05) among nematode numbers and yields of good or rotten berries, and with disease ratings. Nematodes were apparently not involved in the e...
