Accumulation of Al in Root Mucilage of an Al-Resistant and an Al-Sensitive Cultivar of Wheat
Download1996
Archambault, D. J., Zhang, G., Taylor, G. J.
To estimate rates of Al accumulation within the symplasm, all apoplastic pools of Al need to be eliminated or accounted for. We have developed a revised kinetic protocol that allows us to estimate the contribution of mucilage-bound Al to total, nonexchangeable Al, and to eliminate the mucilage as...

Caenorhabditis elegans microtubule-severing complex MEI-1/MEI-2 katanin interacts differently with two superficially redundant beta-tubulin isotypes
Download2004
Srayko, M., Mains, P.E., Lu, C.
The microtubule-severing protein complex katanin is required for a variety of important microtubule-base morphological changes in both animals and plants. Caenorhabditis elegans katanin is encoded by the mei-1 and mei-2 genes and is required for oocyte meiotic spindle formation and must be...

After hormonal ablation, 90% of the secretory epithelial cells of the prostate undergo apoptosis, and the remaining cells are reorganized as the tissue is remodeled. Using differential display RT-PCR of total RNA extracted from the rat ventral prostate before and 4 days after castration, we have...

Background: The MS4A gene family in humans includes CD20 (MS4A1), FcRb (MS4A2), Htm4 (MS4A3), and at least 13 other syntenic genes encoding membrane proteins, most having characteristic tetraspanning topology. Expression of MS4A genes is variable in tissues throughout the body; however, several...

Structural and Biochemical Changes in Loblolly Pine (Pinus taeda L.) Seeds During Germination and Early-Seedling Growth. I. Storage Protein Reserves
Download1997
Abstract: Quantitative and qualitative changes in the storage proteins of loblolly pine (Pinus taeda L.) seeds were followed during germination and early-seedling growth and were correlated with light-microscopic observations. In both the megagametophyte and the embryo, the cells of tissues from...

The procambium specification gene Oshox1 promotes polar auxin transport capacity and reduces its sensitivity toward inhibition
Download2002
Meijer, A. H., Reub, S., Boot, K. J. M., Scarpella, E.
The auxin-inducible homeobox gene Oshox1 of rice (Oryza sativa) is a positive regulator of procambial cell fate commitment, and its overexpression reduces the sensitivity of polar auxin transport (PAT) to the PAT inhibitor 1-N-naphthylphthalamic acid (NPA). Here, we show that wild-type rice...

Visualization of dynein-dependent microtubule gliding at the cell cortex: implications for spindle positioning
Download2011
Dynein motors move along the microtubule (MT) lattice in a processive “walking” manner. In the one-cell Caenorhabditis elegans embryo, dynein is required for spindle-pulling forces during mitosis. Posteriorly directed spindle-pulling forces are higher than anteriorly directed forces, and this...
