Tweaking A 'Hybrid Vigor' Gene Could Generate Higher Crop Yields

Cold Spring Harbor Laboratory Every gardener knows the look of a ripe tomato. That bright red color, that warm earthy smell, and the sweet juicy flavor are hard to resist. But commercial tomato plants have a very different look from the backyard garden variety, which can grow endlessly under the right conditions to become tall and lanky. Tomatoes that will be canned for sauces and juice are harvested from plants that stop growing earlier than classic tomato varieties, and are therefore...

Research pinpoints how plants know when to flower
2012-05-28 06:11:52

Scientists believe they've pinpointed the last crucial piece of the 80-year-old puzzle of how plants "know" when to flower. Determining the proper time to flower, important if a plant is to reproduce successfully, involves a sequence of molecular events, a plant's circadian clock and sunlight. Understanding how flowering works in the simple plant used in this study — Arabidopsis — should lead to a better understanding of how the same genes work in more complex plants grown...

It's Official: Warm Weather Causes Flowers To Bloom
2012-03-22 12:16:28

Scientists have completed research in attempts to explain what  we see in our parks and gardens every year: with the onset of warmer weather comes blooming flowers and trees. Funded by the Biotechnology and Biological Sciences Research Council (BBSRC), scientists from the John Innes Center have investigated the effects of warm weather and global climate changes on flowering plants and trees. Their findings on this research will be published soon in the journal Nature. The research...

Scientists have uncovered a new piece in the puzzle about why some plants flower in spring/autumn and some in summer A team of researchers from Warwick have isolated a gene responsible for regulating the expression of CONSTANS, an important inducer of flowering, in Arabidopsis. 'Being able to understand and ultimately control seasonal flowering will enable more predictable flowering, better scheduling and reduced wastage of crops', explained Dr Jackson. Whilst the relationship between...

Spectacularly increased yields and improved taste have been achieved with hybrid tomato plants by researchers at the Robert H. Smith Faculty of Agriculture, Food and Environment at the Hebrew University and the Cold Spring Harbor Laboratory (CSHL), New York. The researchers have discovered the yield-boosting power of a single gene, which controls when plants make flowers and that works in different varieties of tomato and, crucially, across a range of environmental conditions. The discovery...

The blossoms of cherry trees are celebrated in many places including the Jefferson Memorial in Washington, DC, or Ueno Park in Tokyo, Japan, because they tell us that spring has finally arrived. As we all know, most plants make flowers only at certain times of the year, the spring blooms of cherry trees being but one example. Plants can use several cues from the environment to choose the season that is right for flowering. For example, some plants such as tulips will not flower unless...

Researchers at the Umeå Plant Science Centre at the Swedish University of Agricultural Sciences (SLU), Sweden, report about a breakthrough in our understanding of how plants control their flowering. In an article published in the international journal Science, Thursday 11th, they show how a small molecule that is formed in the plant leaves is transported to the shoot tips where it induces the formation of flowers. This knowledge can lead to the development of new tools that...
