Controlled transmission of African cassava mosaic virus (ACMV) by Bemisia tabaci from cassava (Manihot esculenta Crantz) to seedlings of physic nut (Jatropha curcas L.)

Occurrence of African cassava mosaic virus (ACMV) and East African cassava mosaic virus – Uganda (EACMV-UG) in Jatropha curcas

Background Jatropha curcas is a drought resistant shrub native in tropical America, now widely grown in many tropical and subtropical regions for biodiesel production [1]. First reports on virus infections in Jatropha indicated the occurrence of viruses closely related to Cassava mosaic virus in India, reaching a disease incidence from 25 to 47%. This might represent a major constrain to the pr...

ECOLOGY AND BEHAVIOUR Bemisia tabaci (Homoptera: Aleyrodidae) Biotypes in India

Host plant performance, esterase, and virus transmission tests revealed cassava-strain and sweetpotato-strain populations of whiteßy Bemisia tabaci (Gennadius) biotypes in India. Individuals from the sweetpotato-reared population did not breed on cassava, Manihot esculenta Crantz, and the cassava-strain-reared individuals failed to develop on sweetpotato, Ipomoea batatus (L.) Lam. Eggplant, Sol...

Anatomical alterations due to polyploidy in cassava, Manihot esculenta Crantz.

Information on anatomical structure is needed by breeders working on improvement for drought tolerance. For studying the effect of polyploidy on cassava anatomy and its significance to tolerance to drought, we induced a polyploidy type of a selected clone (UnB 530) by applying an aqueous solution of 0.2% colchicine on lateral buds for a period of 12 h. The stem identified as tetraploid was prop...

Unveiling the Micronome of Cassava (Manihot esculenta Crantz)

MicroRNAs (miRNAs) are an important class of endogenous non-coding single-stranded small RNAs (21-24 nt in length), which serve as post-transcriptional negative regulators of gene expression in plants. Despite the economic importance of Manihot esculenta Crantz (cassava) only 153 putative cassava miRNAs (from multiple germplasm) are available to date in miRBase (Version 21), and identification ...
