Loss of CMD2‐mediated resistance to cassava mosaic disease in plants regenerated through somatic embryogenesis
Cassava mosaic disease (CMD) and cassava brown streak disease (CBSD) are the two most important viral diseases affecting cassava production in Africa. Three sources of resistance are employed to combat CMD: polygenic recessive resistance, termed CMD1, the dominant monogenic type, named CMD2, and the recently characterized CMD3. The farmer-preferred cultivar TME 204 carries inherent resistance t...
متن کاملThe use of biolistic inoculation of cassava mosaic begomoviruses in screening cassava cultivars from Ghana for resistance/susceptibility to cassava mosaic disease
The resistance/susceptibility of 5 cassava cultivars from Ghana to infectious clones of two cassava mosaic viruses (ACMV-[CM] and EACMV/ACMV-[CM]) was investigated in this study. Plantlets of cassava cultivars were obtained using nodal cuttings initiated from tissue culture. These cassava cultivars were challenged with both DNA A and B components of the infectious clones named above using parti...
متن کاملTwo Novel DNAs That Enhance Symptoms and Overcome CMD2 Resistance to Cassava Mosaic Disease
UNLABELLED Cassava mosaic begomoviruses (CMBs) cause cassava mosaic disease (CMD) across Africa and the Indian subcontinent. Like all members of the geminivirus family, CMBs have small, circular single-stranded DNA genomes. We report here the discovery of two novel DNA sequences, designated SEGS-1 and SEGS-2 (forsequencesenhancinggeminivirussymptoms), that enhance symptoms and break resistance ...
متن کاملAutomated Vision-Based Diagnosis of Cassava Mosaic Disease
Cassava Mosaic Disease (CMD) has been an increasing concern to all countries in sub-Saharan Africa that depend on cassava for both commercial and local consumption. Information about the countrywide spread of this disease is difficult to obtain due to logistics and human resource issues in these countries. The objective of this study was to assess the feasibility of automated computer vision ba...
متن کاملResistance to Sri Lankan Cassava Mosaic Virus (SLCMV) in Genetically Engineered Cassava cv. KU50 through RNA Silencing
Cassava ranks fifth among the starch producing crops of the world, its annual bioethanol yield is higher than for any other crop. Cassava cultivar KU50, the most widely grown cultivar for non-food purposes is susceptible to Sri Lankan cassava mosaic virus (SLCMV). The objective of this work was to engineer resistance to SLCMV by RNA interference (RNAi) in order to increase biomass yield, an imp...
