M.1200831The study was conducted to elucidate the diverse change in the amount of cellular pigment contents of papaya leaves infected with different biological variants of Papaya ring spot virus-Papaya strain (PRSV-P). Among the naturally prevailing PRSV-P strains in Bangladesh 7 different and distinctly defined ailments of symptoms, namely Mild mosaic, mosaic, fern leaf, severe mosaic, vein clearing, leaf distortion and chlorotic leaf spot has been selected to conduct the tests of this experimentation. Different partition of cellular pigments (Chlorophyll-a, Chlorophyll-b and ß-carotene) were measured to quantify the alteration of cellular components. For every partition of pigments tested, the highest alteration was found in leaf bearing leaf distortion symptom. In most of the cases the lowest shift in pigment content was determined with the leaf showing Mild Mosaic symptom followed by the mosaic, severe mosaic, vein clearing, chlorotic leaf spot, fern leaf and leaf distortion symptom, respectively. The variability in all the partition of pigments contents alteration was found to be consistently correlated with 7 symptomatic variants of PRSV-P.]]>Akanda, A.M., N. Alam, A. Kahir and A.
