Dr. Gerard Krewer from the Department of Horticulture at the University of Georgia’s College of Agriculture and Environmental Sciences, collected pumpkin seeds in remote areas of Brazil in 1996. The Brazilian seeds were then planted in laboratories, hybridized, and ultimately used to develop ‘Orange Bulldog’.
Dr. George Boyhan, Assistant Professor and Extension Horticulturist at the University of Georgia and lead author of the study published in the October 2007 issue of HortScience, explained that pumpkins have not been readily available in southern states because conventional pumpkins are highly susceptible to viruses and often die before they produce fruit.
The research team set out to develop a virus-resistant pumpkin with bright orange color and an open cavity that would be suitable for Halloween carving. According to Boyhan, ‘Orange Bulldog’ seeds “consistently produced fruit during fall production, whereas commercial pumpkin cultivars often succumb to severe virus infections before fruiting.”
Although ‘Orange Bulldog’ is not yet available to growers or the public, Boyhan’s team hopes that a commercial supplier will soon handle the seeds and make the new pumpkin available to pick-your-own pumpkin growers and consumers.

Killer Electrons Surf Celestial Tsunamis
It's as if we took a trip into space with our best friends, and they turned into mutants and attacked us. Electrons are the best friends we've ever had from the subatomic world. We harness their flow as electricity to power all of modern life -- everything from cell phones and laptops to light bulbs. In space, however, electrons can turn against us. Boosted to almost the speed of light, "killer electrons" can knock out computers, pierce spacesuits, and damage the tissues of astronauts. New research using NASA's STEREO spacecraft is discovering exactly how this happens.

Pumpkin: A fairytale end to insulin injections?
Compounds found in pumpkin could potentially replace or at least drastically reduce the daily insulin injections that so many diabetics currently have to endure. Recent research reveals that pumpkin extract promotes regeneration of damaged pancreatic cells in diabetic rats, boosting levels of insulin-producing beta cells and insulin in the blood, reports Lisa Richards in Chemistry & Industry, the magazine of the SCI.

Flowering Signal Found

The length of the day relative to night, or photoperiod, is a strong determining factor for the induction of flowering in many plant species. Short day (SD) plants require a short day length (or more precisely, a long night) in order to flower. These are plants that flower as the days grow shorter, such as in the fall in temperate regions. Long day (LD) plants will flower when nights are short (and days are long), and typically flower in late spring or early summer. SD crops include rice and maize, and LD crops include wheat, barley, oats and peas. Day-neutral plants will flower under either long or short days. In addition to its fundamental importance in basic plant biology, understanding and manipulating the photoperiodic control of flowering time is an important objective in crop breeding and development programs, because it can aid in optimizing crop yields and other traits for local environmental conditions.
