There is limited information available on production of trailing blackberry, particularly certified organic plantings, which are of interest to growers as there is increased consumer demand and a price premium over conventionally-produced fruit. Various production strategies were evaluated for their effect on yield, biomass production, carbon (C), and nutrient concentrations...
The Pentatricopeptide Repeat (PPR) gene family produces RNA-binding proteins that target organellar transcripts. The PPR family is expanded in land plants, with nearly 450 genes identified in Arabidopsis thaliana. In plants with a Cytoplasmic Male Sterility (CMS) phenotype, members of the PPR family can act as a RESTORER OF FERTILITY...
Vegetative propagation allows the amplification of selected genotypes for research,
breeding, and commercial planting. However, efficient in vitro regeneration and
genetic transformation remains a major obstacle to research and commercial
application in many plant species. Our aims are to improve knowledge of gene
regulatory circuits important to meristem organization, and...
European hazelnut, Corylus avellana L., is the only economically important nut crop
in the family Betulaceae. One of the threats to the hazelnut industry in the Pacific
Northwest is the fungal disease eastern filbert blight (EFB) caused by the
pyrenomycete Anisogramma anomala. Host genetic resistance to EFB identified in the...
The profile of the inner-tubing gas pressure for a tubular membrane aeration system was quantified. The correlations among the overall volumetric oxygen transfer coefficient (k[subscript L]a), the inner-tubing pressure, the tubing tightness, and the gas throughput are experimentally analyzed. A mathematical model was developed to describe the underlying phenomena. The...
Eukaryotic small RNA (~20-30 nucleotides) are diverse regulatory molecules that repress gene expression at the transcriptional and post-transcriptional levels, defend hosts against invading viruses and defend genomes against selfish DNA elements. Small RNA populations are studied by high-throughput sequencing of the total small RNA fraction isolated from cells, however, the...
