A new journal article has been published that reports the discovery of two novel DNA sequences designated as SEGS-1 and SEGS-2 (sequences enhancing geminivirus symptoms) which enhance symptoms and break resistance to CMD. The SEGS are characterized by GC-rich regions and the absence of long open reading frames. Both SEGS enhanced CMD symptoms in cassava (Manihot esculenta Crantz) when co-inoculated with African cassava mosaic virus (ACMV), East African cassava mosaic Cameroon virus (EACMCV) or East African cassava mosaic virus-Uganda (EACMV-UG). You can read the full article online at the American Society of Microbiology, Journal of Virology >>>>
