Some cytological aspects of streak mottle virus in Lilium speciosum Thunberg

Creator:: Elser, John Elmore
Abstract:: Cultivated lilies include many garden varieties in addition to the Easter lily, Lilium longiflorum Thunb. A popular member of the garden group is Lilium speciosum Thunb., whose leaves can be discolored by a virus symptom described as streak mottle. This disorder is characterized by dashes of chlorotic tissue interspersed with...

Ecotypic adaptation of Setaria lutescens (Weigel) F. T. Hubbard to alfalfa culture in California

Creator:: Schoner, Carl Arnold
Abstract:: Setaria lutescens (yellow foxtail) plants, grown from five seed sources were compared in California. Seed sources were: Connecticut, Iowa, Massachusetts, Pennsylvania and California. Morphological and physiological differences between biotypes include: plant size, growth habit, time required to mature and reproductive capa city. Most significant is the prostrate habit of the...

Ozone flux in Helianthus annuus (L.)

Creator:: Smith, Elaine D.
Abstract:: Sunflower (Helianthus annuus L., cv. NK894) seedlings, grown hydroponically, were exposed to ozone concentrations of 0.0, 0.1, 0.2, and 0.3 ppm at 60% RH, or 0.0 and 0.3 ppm at 30% and 90% RH, for 6 h/d, for four consecutive days, at ages 15 to 18 days from seeding. Plant...

The Gac regulon of Pseudomonas fluorescens SBW25

Creator:: Cheng, Xu, de Bruijn, Irene, van der Voort, Menno, Loper, Joyce E., and Raaijmakers, Jos M.
Abstract:: Transcriptome analysis of Pseudomonas fluorescensSBW25 showed that 702 genes were differentially regulated in a gacS::Tn5 mutant, with 300 and 402 genes up- and downregulated respectively. Similar to the Gac regulon of other Pseudomonas species, genes involved in motility, biofilm formation, siderophore biosynthesis and oxidative stress were differentially regulated in the...

Male gametophyte specific expression helps identify a conserved gene associated with increased pollen fitness

Creator:: Colebrook, Sean Jr., Unger-Wallace, Erica, and Vollbrecht, Erik
Abstract:: GRMZM2G372877 was identified as a gene with potential function in the male gametophyte based on its strong expression in mature pollen relative to other maize tissues (Chettoor et al. 2014). Identification of a Ds insertion mutation in this gene from the Brutnell/Vollbrecht collection provided further support for this hypothesis, as...

Identification and characterization of seven ROP GTPases in Zea mays

Creator:: Christensen, Todd M.
Abstract:: Regulation of cell division and expansion are critical for plant development. The mechanisms that control these processes are not clearly understood in higher plants. In other eukaryotic models it has been shown that the highly conserved Rho family GTPases play a crucial role in these mechanisms. One distinct subset of...

A systematic and ecological study of Astragalus diaphanus (Fabaceae)

Creator:: Wright, Carolyn E.
Abstract:: Astragalus diaphanus is a rare plant endemic to the John Day River drainage of north-central Oregon. This species has several interesting features, including the dimorphism of its fruit and its geographical isolation from the two nearest taxonomically related species, which occur in Colorado. This study addressed the species' distribution and...
