Discovery 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 کاملFully leafed induced subtrees
Let G be a simple graph of n vertices. We consider the problem IS` of deciding whether there exists an induced subtree with exactly i ≤ n vertices and ` leaves inG. We also study the associated optimization problem, that consists in computing the maximal number of leaves, denoted by LG(i), realized by an induced subtree with i vertices, for 2 ≤ i ≤ n. We compute the values of the map LG for som...
متن کاملParticle film affects black pecan aphid (Homoptera: Aphididae) on pecan.
Three species of aphids attack pecan foliage, Carya illinoensis (Wang.) K. Koch, and cause economic damage. We tested a kaolin-based particle film against one of these aphid species, black pecan aphid, Melanocallis caryaefoliae (Davis). Effect of particle film on host selection, adult mortality, and production of nymphs by M. caryaefoliae was tested on seedling pecans in the laboratory. Fewer M...
متن کاملPecan Tree Biomass Estimates
Allometric equations were developed for orchard-grown pecan [Carya illinoinensis (Wangenh.) C. Koch] trees. Trees, ranging in size from 22 to 33 cm in trunk diameter 1.4 m above the ground, were destructively harvested from two sites. The entire aboveground portion of each tree was harvested and then divided into leaves, current season’s shoots, and branches $1 year old plus trunk. Roots were s...
متن کاملSafety studies conducted on pecan shell fiber, a food ingredient produced from ground pecan shells
Use of pecan shell fiber in human food is presently limited, but could increase pending demonstration of safety. In a 91-day rat study, pecan shell fiber was administered at dietary concentrations of 0 (control), 50 000, 100 000 or 150 000 ppm. There was no effect of the ingredient on body weight of males or females or food consumption of females. Statistically significant increases in food con...
