Geminiviruses are single-stranded circular DNA viruses causing leaf curl disease in papaya crop. Post-Transcriptional Gene Silencing (PTGS), also known as RNAi, acts as a natural antiviral defence mechanism and plays a role in genome maintenance and development in plants. PTGS suppression by viruses makes the plant RNA silencing machinery inefficient. Three geminiviral genes namely AV2, AC2 and...

Conserved noncoding sequences (CNSs) in DNA are reliable pointers to regulatory elements controlling gene expression. Using a comparative genomics approach with four dicotyledonous plant species (Arabidopsis thaliana, papaya [Carica papaya], poplar [Populus trichocarpa], and grape [Vitis vinifera]), we detected hundreds of CNSs upstream of Arabidopsis genes. Distinct positioning, length, and en...

Natural senescence is associated with several fold increase in activity of protease and is characterized by the degradation and loss of proteins therefore plant proteases have been a common studied interestingly. Protease from senesced leaves of the papaya plant (Carica Papaya) was partially purified by ammonium sulfate precipitation. It showed 15 fold purification. Optimum protease activity wa...

BACKGROUND This paper is based on ethnobotanical interviews conducted from 1996-2000 in Trinidad and Tobago with thirty male and female respondents. METHODS A non-experimental validation was conducted on the plants used for urinary problems and diabetes mellitus: This is a preliminary step to establish that the plants used are safe or effective, to help direct clinical trials, and to inform C...

To enhance the tenderness of meat, it can be accomplished physically or chemically. In chemical way, process using protease enzymes that obtained from fruit, higher enzyme activity, softer meat. this experiment, extract and juice melinjo skin (Gnetum gnemon L) was used to examine activity. Papaya (Carica papaya) pineapple (Ananas comosus) were as a comparison. The research conducted understand ...

BACKGROUND The leaf concentrate of Carica papaya is a traditionally acclaimed immunomodulatory remedy against numerous diseases; nonetheless comprehensive scientific validation of this claim is limited. The present study thus investigated the immunomodulatory potential of Carica papaya mature leaf concentrate (MLCC) of the Sri Lankan wild type cultivar using nonfunctional and functional immunol...

ETHNOPHARMACOLOGICAL RELEVANCE Carica papaya is traditionally used to treat various skin disorders, including wounds. It is widely used in developing countries as an effective and readily available treatment of various wounds, particularly burns. THE AIM OF THE STUDY This study was aimed at investigating the healing efficiency of papaya latex formulated as 1.0 and 2.5% hydrogels. MATERIALS ...

The aim of the present work is the evaluation of anti cancer effect of Carica papaya aerial parts extracts and also the investigation of the phytoconstituents from the extracts of the plant. Petroleum ether (40-60C), Chloroform, ethyl acetate and methanol 80% extracts of C. papaya aerial parts were tested for their anti cancer activity on three cancer cells TK10 (renal), UACC62 (melanoma) and M...
