FRIENDS WITH BENEFITS; NATURAL ENEMIES AND POLLINATORS IN VIRGINIA CUCURBIT PRODUCTION. James M. Wilson & Thomas P. Kuhar, Department of Entomology, Virginia Tech, Blacksburg, Virginia 24061. Cucurbit production in Virginia provides the commonwealth with melons, pumpkins, summer squashes, and cucumbers, all of which are dependent upon adequate pollination for fruit set and development. Growers ...

Guest induced shape change of the cucurbit[8]uril cavity is likely rate limiting in the supramolecular photocatalytic cycle for CB8 mediated photodimerization of 6-methylcoumarin.

The 2b protein encoded by Cucumber mosaic virus (CMV) has been shown to be a silencing suppressor and pathogenicity determinant in solanaceous hosts, but a movement determinant in cucumber. In addition, synergistic interactions between CMV and Zucchini yellow mosaic virus (ZYMV) have been described in several cucurbit species. Here, it was shown that deletion of the 2b gene from CMV prevented e...

How a homogeneous collective of cells consistently and precisely establishes long-range tissue patterns remains a question of active research. This work explores the hypothesis of plant organs as resonators for electromagnetic radiation. Long-range structural patterns in the developing ovaries and male flower buds of cucurbit plants (zucchini, acorn, and butternut squash), in addition to mature...

We examined complexes between cucurbit[6]uril and each of ortho-, meta-, and para-phenylenediamine using computational methods, Fourier transform ion cyclotron resonance mass spectrometry, and ion mobility spectrometry. These fundamental gas phase studies show that the lowest energy binding sites for ortho- and meta-phenylenediamine are on the exterior of cucurbit[6]uril, whereas para-phenylene...

The application of supramolecular chemistry to proteins provides a means of reversibly controlling protein properties. For example, proteins have been decorated with synthetic guest ligands for immobilization on host-molecule-modified surfaces, and vesicles decorated with b-cyclodextrin have been used as a platform to immobilize adamantane-modified enzymes. The supramolecular dimerization of tw...
