| cinnamrutinoses a and b, glycosides of populus tremula. | the cinnamylrutinosides, cinnamrutinoses a and b, were isolated along with known phenolic glucosides, from the stem bark of populus tremula infected with the pathogenic fungus hypoxylon mammatum. the structures were determined from spectroscopic and chemical evidence. | 1994 | 7764484 |
| bacterial disease resistance of transgenic hybrid poplar expressing the synthetic antimicrobial peptide d4e1. | important losses in poplar productivity occur because of susceptibility to microbial pathogens. to enhance disease resistance in susceptible genotypes, the gene coding for d4e1, a synthetic antimicrobial peptide consisting of 17 amino acid residues, was introduced into poplar (populus tremula l. x populus alba l.) via agrobacterium-mediated transformation. four kanamycin-resistant transformants were selected based on significant accumulation of the d4e1 transcript and confirmed by reverse transc ... | 2003 | 12642242 |
| north american populations of entoleuca mammata are genetically more variable than populations in europe. | entoleuca mammata (syn. hypoxylon mammatum) is a damaging pathogen of populus tremuloides and p. grandidentata in north america and p. tremula in europe, where the fungus occurs only sporadically in alpine regions and scandinavia. it has been hypothesized that e. mammata was introduced to europe from north america. in this study, e. mammata isolates collected from europe and north america were compared by a sequence analysis of two dna markers derived from dna fingerprints. the objective of the ... | 2004 | 15446709 |
