Yorkstar wheat, grown in New York State, has a high percentage (10-11) of grains without embryos. The embryoless grains have viable aleurone layers and show no sign of injury. These grains are able to support alpha-amylase synthesis only in the presence of gibberellin A(3) (GA(3)). In the absence of GA(3) some protein synthesis occurs in embryoless grains(More)
Carboxyl-terminal fragments (CTs) of the amyloid precursor protein have been shown to be highly neurotoxic and are though to contribute to the neuropathology of Alzheimer’s disease. We compared the effects of expressing CT99 in the human neuroblastoma MC65 with the effects of hydrogen peroxide on the parental SK-N-MC cells. CT99 and hydrogen peroxide(More)
The presence of nitrogen inhibits legume nodule formation, but the mechanism of this inhibition is poorly understood. We found that 2.5 mM nitrate and above significantly inhibited nodule initiation but not root hair curling in Medicago trunatula. We analyzed protein abundance in M. truncatula roots after treatment with either 0 or 2.5 mM nitrate in the(More)
We have developed a new protein microarray (ImmunoFlow Protein Platform, IFPP) that utilizes a porous nitrocellulose (NC) membrane with printed spots of capture probes. The sample is pumped actively through the NC membrane, to enhance binding efficiency and introduce stringency. Compared to protein microarrays assayed with the conventional(More)
RNA metabolism of embryo and aleurone of barley grains (Hordeum vulgare L. cv. Himalaya) was studied to elucidate the role of these tissues in the control of alpha-amylase synthesis and germination. The extent of (3)H-uridine incorporated into various RNA classes of the embryo during the first 12 hours of germination was low but constant. Subsequently,(More)
