Draft genome sequence of Fusicladium effusum, cause of pecan scab
Pecan scab, caused by the plant pathogenic fungus Fusicladium effusum, is the most destructive disease of pecan, an important specialty crop cultivated in several regions of the world. Only a few members of the family Venturiaceae (in which the pathogen resides) have been reported sequenced. We report the first draft genome sequence (40.6 Mb) of an isolate F. effusum collected from a pecan tree...
متن کاملMicroscopic Examination of Race-specific Resistance to Pecan Scab From the 2001 Southeastern Pecan Growers Association Meeting
Many important high quality cultivars are becoming increasingly susceptible to the scab pathogen. Two such cultivars, 'Stuart' and 'Desirable', comprise over one half of Georgia's total pecan acreage. This increasing susceptibility has often been attributed to the increased prevalence of once rare races of scab that are able to infect these cultivars. Demaree and Cole (1929) were the first to d...
متن کاملDiscovery and small RNA profile of Pecan mosaic-associated virus, a novel potyvirus of pecan trees
A novel potyvirus was discovered in pecan (Carya illinoensis) showing leaf mosaic symptom through the use of deep sequencing of small RNAs. The complete genome of this virus was determined to comprise of 9,310 nucleotides (nt), and shared 24.0% to 58.9% nucleotide similarities with that of other Potyviridae viruses. The genome was deduced to encode a single open reading frame (polyprotein) on t...
متن کاملThe Ramsey numbers of large trees versus wheels
For two given graphs G1 and G2, the Ramseynumber R(G1,G2) is the smallest integer n such that for anygraph G of order n, either $G$ contains G1 or the complementof G contains G2. Let Tn denote a tree of order n andWm a wheel of order m+1. To the best of our knowledge, only R(Tn,Wm) with small wheels are known.In this paper, we show that R(Tn,Wm)=3n-2 for odd m with n>756m^{10}.
