Cellular forms of the DNA of the caulimovirus figwort mosaic virus (FMV), isolated from Datura stramonium leaves and callus cells derived from FMV-infected leaf tissue, have been studied. One- and two-dimensional gel electrophoresis and blot hybridization experiments showed the presence of various truncated forms of FMV DNA reminiscent of the putative replication intermediates of cauliflower mosaic virus (CaMV) thought to be generated by a mechanism involving reverse transcription. FMV DNA was found to be qualitatively and quantitatively similar in leaf and callus tissue, suggesting that, in contrast to CaMV, FMV can multiply efficiently in actively proliferating cells cultured in vitro.

Abstract

One- and two-dimensional gel electrophoresis and blot hybridization experiments showed the presence of various truncated forms of FMV DNA reminiscent of the putative replication intermediates of cauliflower mosaic virus (CaMV) thought to be generated by a mechanism involving reverse transcription. FMV DNA was found to be qualitatively and quantitatively similar in leaf and callus tissue, suggesting that, in contrast to CaMV, FMV can multiply efficiently in actively proliferating cells cultured in vitro.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
