“…Nowadays, there are many varieties of papaya cultivated in most tropical and subtropical regions of the world, differing in traits such as fruit size, color, flavour, and tree size (Moore, 2014). Domesticated plants commonly display a suite of traits, defined as the "domestication syndrome, " that distinguish them from their wild populations or relatives.…”

“…Knowledge of the genetic diversity within crop species is essential to understand their origin, domestication and evolutionary relationships, and to efficiently develop strategies for the conservation of their genetic resources, and effective crop improvement (Moore, 2014). Furthermore, crops represent excellent systems for the study of rapid evolution.…”

A wealth of plant species used by humans for different purposes, but mainly as food, originated and domesticated in the Mesoamerican region. Papaya (Carica papaya) is the third most cultivated tropical crop worldwide, and it has been hypothesized that Mesoamerica is the most likely center of its origin and domestication. In support of it, many wild populations of papaya occur throughout Mesoamerica and hence represent the gene pool of genetic variability for further evolution and future crop management. Despite its importance, a dearth of information exists regarding the status of wild populations of papaya, as compared to the extent of knowledge, and interest, on domesticated varieties. We review the evidence on the extant wild populations of papaya, as well as its origin and distribution. Also, we synthetize what is known on the domestication history of the species, including the domestication syndrome that distinguishes wild and domesticated papayas. Moreover, we make an account of the use of genetic markers to assess genetic diversity of wild and domesticated papaya, and discuss the importance of papaya as the first species with a transgenic cultivar to be released for human consumption, and one that has its complete genome sequenced. Evidence from different disciplines strongly suggest that papaya originated and was domesticated in Mesoamerica, and that wild populations in the region possess, still, high genetic diversity compared to the domesticated papaya. Finally, we outline papaya as an excellent model species for genomic studies that will help gain insight into the domestication process and improvement of papaya and other tropical crops.

“…A domesticação do mamoeiro iniciou na Mesoamérica (Carvalho & Renner, 2012), mas atualmente existe uma gama relativa de cultivares híbridas da planta na maioria das regiões tropicais e subtropicais do mundo, diferindo especialmente quanto a características de tamanho, cor e sabor do fruto (Moore, 2014). A domesticação foi contínua, o que foi crucial para atender à demanda de melhoria da produtividade e da qualidade desta cultura, principalmente devido à expansão produtiva do mamão (Tang, Sezen & Paterson, 2010;Carvalho et al, 2020).…”

O Brasil está entre os principais países produtores e exportadores de mamão (Carica papaya Linnaeus). O mamão é um dos frutos mais importantes na economia e alimentação brasileira, com inúmeras possibilidades industriais e de aplicações nutricionais, farmacológicas e medicinais. Contudo, sua produção no país apresenta aspectos particulares, os quais influenciam as pesquisas científicas sobre o fruto, bem como o mercado consumidor nacional e mundial. Este estudo consiste de uma revisão bibliográfica sobre aspectos e peculiaridades da produção de mamão no Brasil. Foi incluído um breve histórico do mamão; características gerais da planta mamoeiro e do fruto mamão; características de consumo e aplicabilidades industriais do fruto; produção comercial no Brasil; principais cultivares híbridas utilizadas e fatores de risco para a produção, especialmente doenças virais de impacto econômico; aspectos do melhoramento genético do mamoeiro no Brasil; as limitações da transgenia no país e novas estratégias sugeridas. A partir do conjunto de informações deste estudo, são consideradas necessárias pesquisas aplicadas sobre novas tecnologias para a manutenção da produtividade do mamão no Brasil. Para tanto, sugere-se a realização de pesquisas genéticas sobre a hibridização das cultivares comerciais utilizadas com variedades selvagens de mamoeiros da América do Sul e/ou América Central.

“…Flower and fruit characteristics are said to be the most distinguishing and economically important in cultivated papaya (Moore, 2014). Cultivated papayas are hermaphroditic, and fruit shape (typically elongated) and flesh color (ranging from yellow to deep red), in particular, have been the targets of selection during domestication (OECD, 2005;Manshardt & Zee, 1994).…”

The biodiversity of wild crop species can be threatened by genetic introgression of cultivated traits from co-occurring cultivated varieties. The tropical fruit crop, papaya (Carica papaya L.), is a model organism to study questions related to crop-to-wild gene flow because it is cultivated in Central America alongside natural populations. Morphological and genetic diversity was assessed for a collection of naturally occurring papaya individuals from four regions in Panamá, which is the southern-most extent of papaya's range. Significant morphological variation was limited, and fruit characteristics align with typical wild-type traits; fruits are small and round with a thin mesocarp and yellow flesh. Genetic analyses indicated a deficiency in heterozygosity in all regions except the Northeast region. We found moderate levels of population differentiations and regional structuring. This study provides further insight into the natural biodiversity of a tropical crop cultivated in close proximity to its wild counterparts. THE NATURAL DIVERSITY OF CARICA PAPAYA IN PANAMA
