  The diverse nature of shift in the amount of cellular nutritional elements and nucleic acids as affected by the infection of different isolates of Papaya Ring Spot Virus-Papaya strain (PRSV-P) was studied in this experimentation. The symptomatic isolates used in the present study were mild mosaic, mosaic, fern leaf, severe mosaic, vein clearing, leaf distortion and chlorotic leaf spot. Parameters measured to quantify the alteration of cellular components comprised different nutritional cellular elements (C, N, P and K) and nucleic acids (DNA and RNA). In all occasion of measured parameter, the highest alteration was found in leaf distortion. Almost in all cases the lowest effect was determined with the Mild Mosaic infected plants followed by the mosaic, severe mosaic, vein clearing, chlorotic leaf spot, fern leaf and leaf distortion. Infection of seven different symptomatic isolates of PRSV-P created striking and responsive variability in all parameters studied. And the dependency of the cellular nutritional elements and nucleic acid on seven symptomatic variants of PRSV-P was found significantly correlated in respect to the corresponding yield.

  The 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.
