Summary of "Letter to the Editor: Cotton leaf curl Multan betasatellite strains cloned from Gossypium barbadense further supports selection due to host resistance."
The cotton leaf curl Multan betasatellite encodes an essential pathogenicity determinant involved in induction of disease symptoms. We have shown recently that a recombinant betasatellite with a satellite conserved region derived from the tomato leaf curl betasatellite, is prevalent in the Punjab province and is associated with the breakdown of resistance in cotton to cotton leaf curl disease. We intended to see if the betasatellite that was associated with the first epidemic is still being maintained in some other hosts. We cloned betasatellite from G. barbadense, a cotton species highly susceptible to the disease. We found that both the original and recombinant betasatellite are associated with this cotton species. These findings strengthen our hypothesis that the recombinant betasatellite now prevalent on commercial cotton has been selected due to its ability to cross the host resistance barrier.

Medical and Biotech [MESH] Definitions
Work consisting of written or printed communication between individuals or between persons and representatives of corporate bodies. The correspondence may be personal or professional. In medical and other scientific publications the letter is usually from one or more authors to the editor of the journal or book publishing the item being commented upon or discussed. LETTER is often accompanied by COMMENT.
A TEXTILE fiber obtained from the pappus (outside the SEEDS) of cotton plant (GOSSYPIUM). Inhalation of cotton fiber dust over a prolonged period can result in BYSSINOSIS.
Retraction Of Publication
Work consisting of a statement issued by one or more authors of an article or a book, withdrawing or disavowing acknowledgment of their participation in performing research or writing the results of their study. In indexing, the retraction is sent to the editor of the publication in which the article appeared and is published under the rubric "retraction" or in the form of a letter. This publication type designates the author's statement of retraction: it should be differentiated from RETRACTED PUBLICATION which labels the retracted publication.
A plant genus of the family MALVACEAE. It is the source of COTTON FIBER; COTTONSEED OIL, which is used for cooking, and GOSSYPOL. The economically important cotton crop is a major user of agricultural PESTICIDES.
