Strawberry chlorotic fleck: identification and characterization of a novel Closterovirus associated with the disease.

Chlorotic fleck, a strawberry disease caused by a graft and aphid transmissible agent, was identified more than 45 years ago in Louisiana. Since its discovery there has been no additional information on the agent that causes the disease. The mode of transmission implies that a virus is the causal agent of chlorotic fleck. We identified four closteroviruses in the single chlorotic fleck infected...

Elisa detection of grapevine fleck virus ( GFkV )

Résumé — Détection par Elisa du virus de la marbrure de la vigne (GFkV = grapevine fleck virus). L’association du Grapevine fleck virus (GFkV) avec les symptômes de la marbrure de la vigne a été établie par Elisa. La détection par Elisa du GFkV dans les plants de vigne n’est pas possible pendant la totalité du cycle végétatif : dans nos conditions, en Alsace, les mois de juin et juillet c...

Complete Genome Sequences of the Carlavirus Sweet potato chlorotic fleck virus from East Timor and Australia

We present here the first complete genome sequences of Sweet potato chlorotic fleck virus (SPCFV) from sweet potato in Australia and East Timor, and we compare these with four complete SPCFV genomes from South Korea and one from Uganda. The Australian, East Timorese, South Korean, and Ugandan genomes differed considerably from each other.

The Ideas of Ludwik Fleck and Their Application to the Eukaryotic Cell Cycle, the Restriction Point, and G1-phase Control

The ideas of Ludwik Fleck (1896-1961) analyzing the conservative nature of scientific ideas are discussed and applied to the proposed G1-phase restriction point as a regulatory element of the mammalian cell cycle. Fleck proposed that ideas become fixed and difficult to change because criticisms of current and dominant models are either ignored or turned to support of the current model. The idea...
