Tbingen-based developmental geneticists research organ development in the plant embryo In the beginning is the fertilized egg cell. Following numerous cell divisions, it then develops into a complex organism with different organs and tissues. The largely unexplained process whereby the cells simply "know" the organs into which they should later develop is an astonishing phenomenon. Scientists from the Center for Plant Molecular Biology (ZMBP) of the University of Tbingen and the University of...

Molecular biology of drought tolerance comes into focus Recent work at Washington University in St. Louis sheds light on one of the most important events in earth-history, the conquest of land by plants 480 million years ago. No would-be colonizer could have survived on dry land without the ability to deal with dehydration, a major threat for organisms accustomed to soaking in water. Clues to how the first land plants managed to avoid drying out might be provided by bryophytes, a group that...

Max Planck scientists discovered how certain hormones control aspects of root branching in plants Roots are the most underestimated parts of a plant, even though they are crucial for water and nutrient uptake and consequently growth. In a world of changing water availability and an ever-increasing human population, it will therefore be crucial to understand how root development is controlled in plants. Scientists at the Max Planck Institute for Developmental Biology in Tbingen, Germany, now...

The innermost secrets of fire's role in the rebirth and renewal of forests and grasslands are being revealed in research that has identified plant growth promoters and inhibitors in smoke. In the latest discovery about smoke's secret life, an international team of scientists are reporting discovery of a plant growth inhibitor in smoke. The study appears in ACS's Journal of Natural Products, a monthly publication. "Smoke plays an intriguing role in promoting the germination of seeds of many...

Structural study at EMBL reveals how plants respond to water shortages Much as adrenaline coursing through our veins drives our body's reactions to stress, the plant hormone abscisic acid (ABA) is behind plants' responses to stressful situations such as drought, but how it does so has been a mystery for years. Scientists at the European Molecular Biology Laboratory (EMBL) in Grenoble, France, and the Consejo Superior de Investigaciones Cientificas (CSIC) in Valencia, Spain discovered that the...

Light manipulation technique effective, environmental alternative for growing holiday favorite Poinsettias can be a lucrative crop for ornamental plant growers, particularly during the Christmas season. In the temperate regions of the southern hemisphere, where poinsettias are grown for both export and local markets, high-demand time for holiday sales occurs during the summer, when warm temperatures and stronger light can accelerate plant growth, often resulting in unmarketable plants. To...

Scientists have shown that the main shoot dominates a plant's growth principally because it was there first, rather than due to its position at the top of the plant. Collaborating teams from the University of York in the UK and the University of Calgary in Canada combined their expertise in molecular genetics and computational modeling to make a significant discovery that helps explain why pruning encourages plants to thrive. Understanding of the action and interaction of these hormones can...

Researchers in Japan have hopes of enabling farmers to grow high-yielding rice species in flood-prone areas after they have identified two genes that make rice plants grow longer stems and survive floods. The long-stemmed deepwater rice varieties are prone to growing in frequently flooded areas and have very low yields. "In southeast Asia, there are floods in the rainy season and deepwater rice is planted in these regions. But they have yields that are only one third or one quarter that of...

Strigolactones are plant hormones, which were first discovered in crop plants during the infection with the parasitic plant "Striga". Only plants which produce strigolactones were infected with the parasite resulting in a significant reduction of vigor. Moreover, this signaling pathway plays also an important role in plants to initiate symbiotic interactions with mycorrhiza fungi to enhance the absorption of nutrients from the soil. The third hormonal effect known so far is an influence on...

Researchers at the universities of Leicester and Oxford have made a discovery about plant growth which could potentially have an enormous impact on crop production as global warming increases. Dr Kerry Franklin, from the University of Leicester Department of Biology led the study which has identified a single gene responsible for controlling plant growth responses to elevated temperature. Dr Franklin said: "Exposure of plants to high temperature results in the rapid elongation of stems and a...


Word of the Day
barratry
  • The offense of persistently instigating lawsuits, typically groundless ones.
  • An unlawful breach of duty on the part of a ship's master or crew resulting in injury to the ship's owner.
  • Sale or purchase of positions in church or state.
This word ultimately comes from the Old French word 'barater,' to cheat.
