Al-Induced, 51-Kilodalton, Membrane-Bound Proteins Are Associated with Resistance to Al in a Segregating Population of Wheat
Download1997
Zhang, G., Good, A., Taylor, G. J., Slaski, J. J., Basu, A.
Incorporation of S-35 into protein is reduced by exposure to Al in wheat (Triticum aestivum), but the effects are genotype-specific. Exposure to 10 to 75 mu M Al had little effect on S-35 incorporation into total protein, nuclear and mitochondrial protein, microsomal protein, and cytosolic...

Amino Acid Utilization in Seeds of Loblolly Pine during Germination and Early Seedling Growth: I. Arginine and Arginase Activity
Download1997
Abstract: The mobilization and utilization of the major storage proteins in loblolly pine (Pinus taeda L.) seeds following imbibition were investigated. Most of the seed protein reserves were contained within the megagametophyte. Breakdown of these proteins occurred primarily following radicle...

Are boreal birds resilient to forest fragmentation? An experimental study of short-term community responses
Download1997
Schmiegelow, F. K. A., Machtans, C. S., Hannon, S. J.
Abstract: We studied the effect of habitat fragmentation on the richness, diversity, turnover, and abundance of bleeding bird communities in old, boreal mixed-wood forest by creating isolated and connected forest fragments of 1, 10, 40, and 100 ha. Connected fragments were linked by 100 m wide...

Cuticle micromorphology of leaves from all 10 species and one variety of the conifer genus Prumnopitys Philippi (Podocarpaceae) was studied with scanning electron microscopy. Both herbarium and preserved specimens were examined and showed no differences in micromorphology. External and internal...

Epulorhiza inquilina sp. nov. from Platanthera (Orchidaceae) and a key to Epulorhiza species
Download1997
McInnis, T. M., Currah, R. S., Zettler, L. W.
Abstract: Epulorhiza inquilina sp. nov. is described from the mycorrhizas of mature plants of Platanthera clavellata, P. cristata and P. integrilabia, coexisting terrestrial orchids native to bogs in the southern Appalachians. The new taxon was isolated consistently and exclusively from these...

Fossil ectomycorrhizae were found recently among permineralized plant remains in the middle Eocene Princeton chert of British Columbia. The ectomycorrhizae are associated with roots of Pinus and have a Hartig net that extends to the endodermis, a pseudoparenchymatous mantle, and contiguous...

Likens, G. E., Vitousek, P. M., Tilman, D., Schindler, D. W., Howarth, R. W., Aber, J. D., Schlesinger, W. H., Matson, P. a.
Nitrogen is a key element controlling the species composition, diversity, dynamics, and functioning of many terrestrial, freshwater, and marine ecosystems. Many of the original plant species living in these ecosystems are adapted to, and function optimally in, soils and solutions with low levels...

Leg size affects male mating success in Tarsonemus confusus Ewing (Prostigmata: Tarsonemidae)
Download1997
Belczewski, R., Garga, N., Proctor, H.
Legs IV of males in the family Tarsonemidae are highly modified to form thickened pincer-like appendages. Previous literature describes males using legs IV both to manipulate pharate females onto the males' genital capsule as well as to constrain the adult female's legs during mating. We observed...
