Morante, NelsonCeballos, H.Sánchez, TeresaRolland-Sabaté, AgnèsCalle, FernandoHershey, Clair H.Gibert, OlivierDufour, D.L.[Discovery of new spontaneous sources of amylose-free cassava starch and analysis of their structure and techno-functional properties]Discovery of new spontaneous sources of amylose-free cassava starch and analysis of their structure and techno-functional properties

Functional properties of normal and waxy starches from maize, rice, potato, and cassava as well as the modified waxy maize starch COLFLO 67 were compared. The main objective of this study is to position the recently discovered spontaneous mutation for amylose-free cassava starch in relation to th...


Sánchez, T.Dufour, D.L.Moreno, I.X.Ceballos, H.[Comparison of pasting and gel stabilities of waxy and normal starches from potato, maize, and rice with those of a novel waxy cassava starch under thermal, chemical, and mechanical stress]Comparison of pasting and gel stabilities of waxy and normal starches from potato, maize, and rice with those of a novel waxy cassava starch under thermal, chemical, and mechanical stress

Using groundnut (Arachis hypogea) and cowpea (Vigna unguiculata), this study empirically demonstrated the correlation between crop storage and economic competitiveness of producers, captured from the degree of market integration and producer shares of the prices paid by consumers, among others. S...

BACKGROUND: Orange-fleshed sweetpotato (OFSP) can be used to tackle vitamin A deficiency, a major public health problem in most developing countries. In East Africa, common ways of using sweetpotato include drying and subsequent storage. The aim of the study was to investigate the impact of dryin...

A prerequisite for biotechnological improvements of storage roots is the availability of tissue-specific promoters enabling high expression of transgenes. In this work, we cloned two genomic fragments, pMe1 and pDJ3S, controlling the expression of a gene with unknown function from cassava (Maniho...

Information on bruchids on bean grain (Zabrotes subfasciatus and Acanthoscelides obtectus) is given for farmers, explaining aspects such as: oviposition behavior, morphological characteristics of the adult, type of damage, and adaptation to temp. Practices to avoid or prevent damage by bruchids a...

Cryopreservation in liquid nitrogen of isolated zygotic embryos and whole seeds of cassava have been studied. A simple method is proposed for utilization in germplasm conservation or other related uses. Very high percentage survival values (ca. 97 percent) of zygotic embryos and whole seeds were ...
