Passionfruit

Abstract

The genus Passiflora comprises a large number of plant species that grow as perennial or semiperennial vines, possess large flowers, and are cross‐pollinated. The plant can also be vegetatively propagated by cuttings or grafting. Yellow passionfruit ( P. edulis f. flavicarpa ) is the most widely planted species. Passionfruit is a crop of relatively recent commercial cultivation, displaying a high degree of genetic variability that can be easily exploited by conventional breeding. The development of cultivars has three main objectives: yield, fruit quality, and disease resistance. Of these, disease resistance has been the least successful and is the one for which biotechnology holds the greatest promises. The most likely short‐term development in terms of passionfruit transgenics is woodiness‐resistant plants. The results obtained so far are promising and indicate that resistance to passionfruit woodiness can be accomplished by expression of virus‐derived genomic fragments. Other desirable products would be plants with uniform fruit maturity, or self‐compatible. However, the biochemical pathways that control fruit setting and maturity, as well as self‐incompatibility in yellow passionfruit, are likely to involve a large number of genes and have not yet been dissected, and therefore such transgenic plants are not likely to be produced in the near future.

A genome sequence resource for the genus Passiflora, the genome of the wild diploid species Passiflora organensis

“…There are four main subgenera: Astrophea (57 species), Decaloba (220 species), Deidamioides (13 species), and the Passiflora subgenus (240 species), which contains several self‐incompatible species (Ulmer & MacDougal, 2004). Although some 50 species are traditionally cropped in temperate regions (e.g., the United States), most are grown in tropical climates to produce fruit (Cerqueira‐Silva et al., 2015; Zerbini et al., 2008).…”

In Vitro Protocols for Ornamental Climbers

“…Standing out among these are P. edulis , P. alata , P. setaceae , P. giberti , P. nitida , P. quadrangularis , and P. cincinnata (Oliveira and Ruggiero 2005 ;Vieira and Carneiro 2004 ;Zerbini et al 2008 ) .…”

Silicon in the Embriogenic Potential of Callus in vitro of Passiflora edulis

“…The tissue culture through the micropropagation is an important method to multiply quickly the high production and/or disease genótipos resistant superiors in the physical space and reduced time, very often offering the only alternatives for programs of plant breeding (Zerbini et al, 2008;. However, the regeneration was seeing embryogenesis somatic be shown to be promising and it has the potential to devote it self in the field of the micropropagation, which is the way morphogenic principal of the regeneration in the type Passiflora (Zerbini et al, 2008;Pinto et al, 2010), in the improvement of result of passion fruit.…”
