Sugarcane Bacilliform Virus: Symptoms, Detection and Distribution in the World Germplasm Collection at Cannanore, India
نویسنده
چکیده
Sugarcane bacilliforin virus (SCBV) was detected in the world collection of sugarcane gerinplasm at Cannanore in recent years. The characteristic foliar syinptolns were freckles, chlorotic stripes of vaiying length, narrowing of leaves, stunted growth, presence of internodal cracks and a "buizclzy top" appearance. Among the different genotypes, those of Sacckarum oflcinaruin appear most prone to tlze virus. Genotypes of S. oflcirzai-unz collected prior to 1970 were heavily infected with tlze virus. Most of the S. barberi and S. sinense genotypes were also infected However only a limited izun~ber of genotypes of S. robustum and interspeciJic Izybricls of this had suspected infection. Enzyine linked immunosorbeizt assa? (ELZSA) and itnnzunosorbent electron nzicroscopy (ISEM) were stanhrdised for tlze detection of virus in the suspected genotypes. The presence of the virus in the sugarcane gerinplasnz in India mzd other countries is a inqjor obstacle to tlze safe exchange of germplasm. Inzmediate attention is warranted to enhance the precision of virus indexing by means of DNA probes and the polynzerase chain reaction and also for eliminating the virus Ji .017~ injected genotypes.

Genetic Analysis of Diversity within a Chinese Local Sugarcane Germplasm Based on Start Codon Targeted Polymorphism
In-depth information on sugarcane germplasm is the basis for its conservation and utilization. Data on sugarcane molecular markers are limited for the Chinese sugarcane germplasm collections. In the present study, 20 start codon targeted (SCoT) marker primers were designed to assess the genetic diversity among 107 sugarcane accessions within a local sugarcane germplasm collection. These primers...

Exploitation of wild relatives of crop plants to a large extent depends on the efficient use of germplasm resources available in natural habitat and the centre of diversity. The mulberry, sole food for silkworm is cultivated for the production and development of silkworm industry. Four species of mulberry viz., M. indica L., M. alba L., M. laevigata Wall., and M. serrata Roxb., are reported in ...
متن کاملCan Trimodal Distribution of HbS Levels in Sickle Cell Traits Be Used To Predict the Associated Alpha-Thalassemia For Screening Cases in Central India?
Background: Until now, trimodal distribution of HbS has been seen by six different studies in the world when associated with alpha-thalassemia with confirmation by corresponding alpha-genotyping studies. The RBC indices reduce as alpha-globin genes reduce in sickle cell trait (SCT) patients, which decreases the extent of intra-vascular sickling and thus betters the clinical cou...

Background: Spine gourd (Momordica dioica Roxb. Willd) is one of the important cucurbitaceous crops grown across the world for vegetable and medicinal purposes. Diseases caused by the DNA viruses are becoming the limiting factors for the production of spine gourd reducing its potential yield. For the commercial cultivation of the spine gourd, propagation material used by most o...
