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...

Barley Takes A Leaf Out Of Reindeer's Book In The Land Of The Midnight Sun
2012-05-11 08:15:25

Barley grown in Scandinavian countries is adapted in a similar way to reindeer to cope with the extremes of day length at high latitudes. Researchers have found a genetic mutation in some Scandinavian barley varieties that disrupts the circadian clock that barley from southern regions use to time their growing season. Just as reindeer have dropped the clock in adapting to extremely long days, so has Scandinavian barley to grow successfully in that region's short growing season. This new...

Valoya Ltd, a leading provider of LED lights for horticultural use, was chosen by the University of Helsinki, Finland, for their strawberry cultivation without sunlight. Helsinki, Finland (PRWEB) March 27, 2012 Researcher Dr. Timo Hytönen and his research team at the University of Helsinki tested several artificial light sources for improving vegetative growth and flowering of wild strawberries. The LED lights from Valoya Ltd were among the tested products and proved to be superior in...

Intermittent light system more cost-effective than incandescent illumination When consumers visit garden centers in spring they will most likely buy flowering ornamental plants that are ready for their home gardens. Studies have shown that consumers favor plants that are already in flower rather than those that are "vegetative""”a preference that can present multiple challenges for commercial growers. To satisfy consumers' wishes, producers of ready-to-flower ornamentals like bedding...

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...

Research published in the journal Genetics allows scientists to overcome barrier for effective crossbreeding of tropical and temperate strains of corn Scientists may have made an "a-maize-ing" discovery that could lead to higher corn yields in the United States. In a new research report published in the March 2010 issue of the journal Genetics, scientists used tropical maize from Mexico and Thailand to discover chromosome regions responsible for detecting seasonal changes in flowering time...
