Aquifex aeolicus DHO, is a dodecamer comprised of six DHO and six aspartate(More)
The weights of pecanCarya illinoensis Koch galls caused by several species ofPhylloxera (Homoptera: Phylloxeridae) were negatively correlated with leaf and nut weights and nut production. Several allelochemicals (isoquercitrin, juglone, and 2 proanthocyanidins) were isolated from galls, and their antibiotic potentials were estimated, based on their toxicity(More)
