Transgenic papaya plants were initially obtained using particle bombardment, a method having poor efficiency in producing intact, single-copy insertion of transgenes. Single-copy gene insertion was improved using Agrobacterium tumefaciens. With progress being made in genome sequencing and gene discovery, there is a need for more efficient methods of ...

Somatic Embryogenesis in Papaya (Carica papaya L.)
2022High mortality rates of in vitro plants during ex vitro acclimatization, due to low rooting, is one of the main problems of papaya tissue culture. This work was carried out with the objective to obtain 100% hermaphroditic in vitro plants of the papaya cultivar "Maradol Roja" by somatic embryogenesis, which have an adequate rooting system that allows ...

Anther culture of papaya (Carica papaya L.)
Plant Cell Reports, 1985Papaya (Carica papaya L.) anther containing microspores in tetrad to early-binucleate stages were successfully cultured on 1/2 strength MS salts and vitamins with full strength Na-Fe-EDTA supplemented with 2 mg/l NAA, 1 mg/l BA and 6% sucrose for callus initiation and formation.

GRAFTING PAPAYAS (CARICA PAPAYA L.)
Acta Horticulturae, 2010Papaya is one of the few fruit crops still propagated by seed. Vegetative propagation by leafy cuttings has been practiced successfully in South Africa for over 40 years, because Papaya ringspot virus has not been a problem. Grafting has been done in various places but problems have arisen locally with bacterial infection of the scions.

Chemical composition of papaya (Carica papaya) seeds
Food Chemistry, 1986Abstract Defatted and undefatted seeds of papaya (Carica papaya) were analyzed for proximate composition, some toxicants, sugar composition, mineral content, physico-chemical properties of the seed oil and the fatty acid spectrum of the seed oil. The seed is a rich source of proteins (27·8% undefatted, 44·4% defatted), lipids (28·3% undefatted) and

Chromosome identification in papaya (Carica papaya)
2004An experiment was conducted to investigate the general cytological condition of papaya. Seed germinated healthy roots were collected from the three different strains of papaya cultivars (P-1, P-2 & P-3). Slides were prepared following 2.5 hours of pretreatment by saturated aqueous solution of monobromonaphthalene (MBN), hydrolysis in 10% HC1 for 10

Genetic Improvement of Papaya (Carica papaya L.)
2018Arising from a relatively isolated center of origin, papaya has spread throughout all tropical and subtropical countries through human intervention. This global dispersal has coincided with continuous improvement of the cultivated plants through breeding programs often designed to improve the agronomic characters and to address biotic and abiotic ...

REGENERATION OF TRANSGENIC PAPAYA (Carica papaya) PLANTS
1990Stable transformation of papaya (Carica papaya L.) has been achieved following DNA delivery via high velocity microprojectiles. Three types of embryogenic tissues, including immature zygotic embryos, hypocotyl sections, and somatic embryos derived from both, were bombarded with tungsten particles carrying chimeric genes coding for NPT II, GUS, and the ...
