First report of Sugarcane mosaic virus in achira (Canna edulis Ker.) in Nariño, Colombia

Characterization of starch from two ecotypes of andean achira roots (Canna edulis).

Starches from two ecotypes of achira roots (Canna edulis Ker-Gawler) were characterized and compared to commercial potato and corn starches. This included scanning electron microscopy (SEM) of starch granules and amylose content determination of starch. Starch solutions or gels were tested by rotational viscometry, Rapid Visco Analyzer (RVA), and texture analysis. Some starch samples were subje...

Sugarcane Mosaic Virus-Based Gene Silencing in Nicotiana benthamiana

Background:Potyvirus-based virus-induced gene silencing (VIGS) is used for knocking down the expression of a target gene in numerous plant species. Sugarcane mosaic virus (SCMV) is a monopartite, positive single strand RNA virus. Objectives:pBINTRA6 vector was modified by inserting a gene segment of SCMV in place of Tobacco rattle virus (TRV) genome part 1 (TRV1 or RNA1)...

Integration of physical and chemical treatment on the extraction of starch from Canna edulis Ker. rhizome

The extraction of Canna edulis Ker. starch from its rhizome was performed using 2 different types of press (hydraulic press and screw press) and with the addition of Na-metabisulphite and NaOH (in the range of concentration 100 5000 ppm each). The optimum condition for this process was determined by Central Composite Design of experiment and the statistical calculation was solved by Design-Expe...
