Elucidating the Clusia criuva species 'complex': Cryptic taxa can exhibit great...
Cortez, Maria Beatriz De S; Sforça, Danilo A; Alves, Fábio De M; Vidal, João De D [UNESP]; Alves-Pereira, Alessandro; Mori, Gustavo M [UNESP]Made available in DSpace on 2020-12-12T01:39:34Z (GMT). No. of bitstreams: 0 Previous issue date: 2019-01-01; In the Clusia criuva Cambess. species complex, the two subspecies C. criuva subsp. parviflora Vesque and C. criuva subsp. criuva can only be distinguished on the basis of stamen/staminode morphology and geographical occurrence. Despite being recently restructured, taxonomic relationships in this complex...
A population genomics appraisal suggests independent dispersals for bitter and ...
Alves-Pereira, Alessandro; Clement, Charles Roland; Picanço-Rodrigues, Doriane; Veasey, Elizabeth Ann; Dequigiovanni, GabrielAmazonia is a major world centre of plant domestication, but the genetics of domestication remains unclear for most Amazonian crops. Manioc (Manihot esculenta) is the most important staple food crop that originated in this region. Although manioc is relatively well-studied, little is known about the diversification of bitter and sweet landraces and how they were dispersed across Amazonia. We evaluated single nu...
Origin and domestication of native Amazonian crops
Clement, Charles Roland; Cristo-Araújo, Michelly de; D'Eeckenbrugge, Geo Coppens; Alves-Pereira, Alessandro; Picanço-Rodrigues, DorianeMolecular analyses are providing new elements to decipher the origin, domestication and dispersal of native Amazonian crops in an expanding archaeological context. Solid molecular data are available for manioc (Manihot esculenta), cacao (Theobroma cacao), pineapple (Ananas comosus), peach palm (Bactris gasipaes) and guaraná (Paullinia cupana), while hot peppers (Capsicum spp.), inga (Inga edulis), Brazil nut (B...
Highly structured genetic diversity of Bixa orellana var. urucurana, the wild a...
Dequigiovanni, Gabriel; Ramos, Santiago Linorio Ferreyra; Alves-Pereira, Alessandro; Fabri, Eliane Gomes; Doriane, Picanço RodriguesAnnatto (Bixa orellana L.) is a tropical American crop, commercially valuable due to its application in the food and cosmetics industries as a natural dye. The wild ancestor of cultivated annatto is B. orellana var. urucurana. Although never cultivated, this variety occurs in open forests and anthropogenic landscapes, and is always associated with riparian environments. In this study, we evaluated the genetic d...
Genetic divergence among populations and accessions of the spineless peach palm...
Alves-Pereira, Alessandro; Clement, Charles Roland; Picanço-Rodrigues, DorianeAlthough originally domesticated for its fruit, exploitation of the peach palm (Bactris gasipaes Kunth) in the production of gourmet heart-of-palm has also become an important activity, hence the need for improved material for large-scale production, on employing the Pampa Hermosa landrace as the seed source. In this study 11 microsatellite markers were used to evaluate genetic divergence among 96 elite plants ...
Convergent Adaptations: Bitter Manioc Cultivation Systems in Fertile Anthropoge...
Fraser, James A.; Alves-Pereira, Alessandro; Junqueira, André Braga; Peroni, Nivaldo; Clement, Charles RolandShifting cultivation in the humid tropics is incredibly diverse, yet research tends to focus on one type: long-fallow shifting cultivation. While it is a typical adaptation to the highly-weathered nutrient-poor soils of the Amazonian terra firme, fertile environments in the region offer opportunities for agricultural intensification. We hypothesized that Amazonian people have developed divergent bitter manioc c...
High genetic diversity among and within bitter manioc varieties cultivated in d...
Alves-Pereira, Alessandro; Peroni, Nivaldo; Cavallari, Marcelo Mattos; Lemes, Maristerra R.; Zucchi, Maria Imaculada; Clement, Charles RolandAlthough manioc is well adapted to nutrient-poor Oxisols of Amazonia, ethnobotanical observations show that bitter manioc is also frequently cultivated in the highly fertile soils of the floodplains and Amazonian dark earths (ADE) along the middle Madeira River. Because different sets of varieties are grown in each soil type, and there are agronomic similarities between ADE and floodplain varieties, it was hypo...
Crop domestication in the upper Madeira River basin
Clement, Charles Roland; Doriane, Picanço Rodrigues; Alves-Pereira, Alessandro; Mühlen, Gilda Santos; Cristo-Araújo, Michelly deMost native Amazonian crops were domesticated in the periphery of the basin. The upper Madeira River basin is an important part of this periphery where several important crops were domesticated and others are suspected to have been domesticated or arrived early. Some of these crops have been reasonably well studied, such as manioc, peanut, peach palm, coca and tobacco, while others are not as well known, such a...
Patterns of nuclear and chloroplast genetic diversity and structure of manioc a...
Alves-Pereira, Alessandro; Clement, Charles Roland; Picanço-Rodrigues, Doriane; Veasey, Elizabeth Ann; Dequigiovanni, GabrielBackground and Aims Amazonia is a major world centre of plant domestication, but little is known about how the crops were dispersed across the region. Manioc (Manihot esculenta) was domesticated in the south-western Amazon basin, and is the most important staple food crop that originated in Amazonia. Current contrasting distributions may reflect distinct histories of dispersal of bitter and sweet manioc landrac...
