A molecular genetic map of cassava (Manihot esculenta Crantz)

Autor: Fregene, Martin A. Angel, F. Gómez, R. Rodríguez, F. Chavarriaga Aguirre, Paul Roca, William M. Tohme, Joseph M. Bonierbale, Merideth W.

A genetic linkage map of cassava has been constructed with 132 RFLPs, 30 RAPDs, 3 microsatellites, and 3 isoenzyme markers segregating from the heterozygous female parent of an intraspecific cross. The F1 cross was made between ‘TMS 30572’ and ‘CM?2177-2’, elite cassava cultivars from Nigeria and...

Cross-species amplification of cassava (Manihot esculenta) (Euphorbiaceae) microsatellites: Allelic polymorphism and degree of relationship

Autor: Roa, AC Chavarriaga Aguirre, Paul Duque E., Myriam Cristina Maya, M.M. Bonierbale, Merideth W. Iglesias, C.A. Tohme, Joseph M.

Microsatellite amplification was performed on cassava (Manihot esculenta) and six other different species (all wild) of the Manihot genus. We used ten pairs of microsatellite primers previously developed from cassava, detecting 124 alleles in a sample of 121 accessions of the seven species. The n...

Identification and characterization of the Cassava core-clock gene Early Flowering 4

Autor: Adeyemo, O. Sarah Kolmos, E Tohme, Joseph M. Chavarriaga Aguirre, Paul Fregene, Martin A. Davis, S.J.

The angiosperm circadian clock has been well established from molecular-genetic studies in a temperate plant model. Conservation of clock function is less explored in plants from the tropics. Cassava (Manihot esculenta) is a staple crop grown in the tropics that has been of limited research inter...

Organogenesis in-vitro using three tissues types of tree tomato [Solanum betaceum (Cav.)] = Organogénesis in-vitro usando tres tipos de tejidos de tomate de árbol [Solanum betaceum (Cav.)]

Autor: Murillo-Gómez, Paola Andrea Hoyos S, Rodrigo Chavarriaga Aguirre, Paul

Tree tomato is a fruit with great economic potential due to its high nutritional value. The induction of direct organogenesis in this species is a great alternative for clonal propagation of disease-free plants, and also useful for genetic transformation. In this study was assessed the induction ...

The potential of using biotechnology to improve cassava: a review

Autor: Chavarriaga Aguirre, Paul Brand, Alejandro Medina, Adriana Prías, Mónica Escobar Pérez, Roosevelt H. Martínez, Juan Díaz, Paula López Carrascal, Camilo Ernesto Roca, William M. Tohme, Joseph M.

The importance of cassava as the fourth largest source of calories in the world requires that contributions of biotechnology to improving this crop, advances and current challenges, be periodically reviewed. Plant biotechnology offers a wide range of opportunities that can help cassava become a b...

Microsatellites in cassava (Manihot esculenta Crantz) : discovery, inheritance and variability

Autor: Chavarriaga Aguirre, Paul Maya, M.M. Bonierbale, Merideth W. Kresovich, S Fregene, Martin A. Tohme, Joseph M. Kochert, G

Fourteen microsatellites containing GA-repeats were isolated and characterized in cassava (Manihot esculenta Crantz, Euphorbiaceae). Microsatellite heterozygosity (h) was estimated in 48 accessions using (32P)-end-labeled primers and in more than 500 accessions using fluorescence-based genotyping...

Provitamin A accumulation in Cassava (Manihot esculenta) roots driven by a single nucleotide polymorphism in a phytoene synthase gene[W]

Autor: Welsch, R Arango, Jacobo Bar, C Salazar, B Al-Babili, S. Beltrán Giraldo, Jorge Alonso Chavarriaga Aguirre, Paul Ceballos, H. Tohme, Joseph M. Beyer, Peter

Cassava (Manihot esculenta) is an important staple crop, especially in the arid tropics. Because roots of commercial cassava cultivars contain a limited amount of provitamin A carotenoids, both conventional breeding and genetic modification are being applied to increase their production and accum...
