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...

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...

An international team of scientists has cracked the problem of pod shatter in brassica crops such as oilseed rape.Just before harvest, oilseed rape pods are prone to shatter, causing a 10-25% loss of seeds and up to 70% in some cases."By artificially producing a hormone in a specific region of the fruit, we have stopped the fruit opening in the related model plant Arabidopsis, completely sealing the seeds inside," says Dr Lars Østergaard from the John Innes Centre....

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...

Ever since insects developed a taste for vegetation, plants have faced the same dilemma: use limited resources to out-compete their neighbors for light to grow, or, invest directly in defense against hungry insects. Now, an international team of scientists at the Salk Institute for Biological Studies and the Institute of Investigaciones Fisiol³gicas y Ecol³gicas Vinculadas a la Agronomía (IFEVA) has discovered how plants weigh the tradeoffs and redirect their...

U.S. agricultural geneticists say they've identified a gene that's essential in controlling development of maize, a plant known in the United States as corn. Led by Cold Spring Harbor Laboratory Professor David Jackson, the research extends the biological understanding of how the different parts of maize arise. That, said Jackson, is important information for a plant that is the most widely planted crop in the United States and a mainstay of the global food supply. The researchers said they...

By Portillo, Liberato Santacruz-Ruvalcaba, Fernando; Gutierrez-Mora, Antonia; Rodriguez-Garay, Benjamin Abstract Somatic embryogenesis was achieved from leaves of Agave tequilana Weber cultivar azul utilizing MS medium supplemented with L2 vitamins and the addition of cytokinins: 6-benzylaminopurine (BA), 1-phenyl-3(1,2,3-thiadiazol-5-yl)urea (TDZ), 6-(gamma-gamma- dimethylamino)purine (2ip) and 6-furfurylaminopurine (KIN), combined with the auxin 2,4-dichlorophenoxyacetic acid (2,4-D)....

By Glick, Bernard R Todorovic, Biljana; Czarny, Jennifer; Cheng, Zhenyu; Duan, Jin; McConkey, Brendan To date, there has been only limited commercial use of plant growth-promoting bacteria in agriculture, horticulture, and silviculture. However, with recent progress toward understanding the mechanisms that these organisms utilize to facilitate plant growth, the use of plant growth-promoting bacteria is expected to continue to increase worldwide. One of the key mechanisms employed by plant...

STORRS, Conn. "“ A team of scientists led by University of Connecticut plant biologist Roberto Gaxiola has discovered an overlooked genetic key to generating plants that are more productive, more drought resistant and can grow in soils low in nutrients. Their work is the first to successfully test in cells a 30-year-old hypothesis that explains the movement of a primary growth and development hormone through plants and is expected to prompt biology textbooks to be rewritten. The...

Agrobacterium tumefaciens is the causal agent of crown gall disease (the formation of tumours) in over 140 species of dicot. It is rod shaped. Symptoms are caused by the insertion of a small segment of DNA into the plant cell. It is an alphaproteobacterium of the family Rhizobiaceae which includes the nitrogen fixing legume symbionts. They are pathogenic and provide no benefit to the plant. It also affects a wide variety of plants. In an economical sense it affects walnuts, grape vines,...
