An unexpected outcome of atmospheric CO2 enrichment
Unseen belowground interactions impact the composition of natural plant communities. Mycorrhizae, symbiotic associations between soil fungi and plant roots, help plants acquire soil nutrients but also drain substantial carbon from plants. Whether mycorrhizae help or hinder plant growth depends upon the balance between nutrient benefits and carbon... view more... (2003-05-22)
ISU researcher identifies genetic pathway responsible for much of plant growth
Researchers at Iowa State University have discovered a previously unknown pathway in plant cells that regulates plant growth. view more (2009-05-21)
Herbal alternative to farmyard antibiotics
Research at the University of Leeds into herbal remedies in the farmyard could soon see pigswill garnished with garlic and cows chewing on cinnamon-flavoured cud. With an EU ban on antibiotic growth promoters in animal feed from 2006, alternatives need to be found urgently. The use of plant extracts, once dismissed as quack science, is attracting... view more... (2004-01-26)
The effects of climate change on the physiology of alfalfa
The biologist Gorka Erice Soreasu, a researcher in the Department of Plant Biology of the University of Navarra, has studied the effects of climate change on the physiology of alfalfa. view more (2006-04-12)
The 'green revolution gene' goes to the root of how plants control their growth.
Scientists at the John Innes Centre (JIC) Norwich(1), have discovered how plants coordinate and control their development by using a master signal to regulate the growth of cells throughout the plant. The signal, a plant hormone called auxin, affects the ability of cells to respond to another hormone (gibberellin(2)) that 'switches on' cell... view more... (2003-02-11)
Scientists find stem cell switch
Scientists have discovered how plant stem cells in roots detect soil structure and whether it is favourable for growth. view more (2007-07-27)
Norwich scientists grow snapdragons in microchips
Scientists from the John Innes Centre (JIC)(1) and University of East Anglia(UEA)(2) in Norwich have today reported that they have been able to ‘grow’ snapdragon(3) petals in a computer. The research team used a computer programme to simulate the growth of snapdragon petals, this allowed them to modify the key processes in petal... view more... (2003-03-10)
Hormone clue to root growth
Plant roots provide the crops we eat with water, nutrients and anchorage. Understanding how roots grow and how hormones control that growth is crucial to improving crop yields, which will be necessary to address food security and produce better biofuels. view more (2009-07-08)
Explaining why pruning encourages plants to thrive
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. view more (2009-09-22)
Study shows vitamin C is essential for plant growth
Scientists from the University of Exeter and Shimane University in Japan have proved for the first time that vitamin C is essential for plant growth. This discovery could have implications for agriculture and for the production of vitamin C dietary supplements. view more (2007-09-24)
Too Much of a Good Thing: Understanding Plants' Overactive Immune System Will Help MU Researchers Build Better Crops
A plant's immune system protects the plant from harmful pathogens. If the system overreacts to pathogens, it can stunt plant growth and reduce seed production. view more (2009-05-28)
The bonsai effect: Wounded plants make jasmonates, inhibiting cell division, stunting growth
It is well known that plants growing under unfavourable conditions are generally smaller than those growing in stress-free conditions: indeed it is estimated that in the US, abiotic stress reduces the yield of agricultural crops by an average of 22%. view more (2008-11-12)
New breakthrough in global warming plant production
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. view more (2009-03-31)
Internal Clock, External Light Regulate Plant Growth
Most plants and animals show changes in activity over a 24-hour cycle. Now, for the first time, researchers have shown how a plant combines signals from its internal clock with those from the environment to show a daily rhythm of growth. view more (2007-07-10)
Distant Attraction
Sopow and colleagues report in the February issue of Ecology Letters that a chemical stimulus from a galling insect changes the morphology and physiology of its host to benefit these specialized plant feeders. Galls are atypical plant growths that provide nourishment and shelter for gall-inducing insects. Previous studies could not determine... view more... (2003-01-29)
Possible new hope for crops battling parasitic infection
Scientists from Ghent University and VIB (The Flemisch Institute for Biotechnology) have demonstrated how nematodes, also known as roundworms, manipulate the transport of the plant hormone auxin in order to force the plant to produce food for them. view more (2009-01-16)
Plentiful poinsettias without PGRs
Poinsettias can be a lucrative crop for ornamental plant growers, particularly during the Christmas season. view more (2009-11-05)
Plants can be used to study how and why people respond differently to drugs
While prescription medications work successfully to cure an ailment in some people, in others the same dose of the same drug can cause an adverse reaction or no response at all. view more (2007-09-27)
Ecosystem consequences of a single, genetically based plant trait
Climate is often touted as the most important regulator of decomposition and nutrient cycling processes in forest ecosystems, however, in the forthcoming issue of Ecology Letters, Schweitzer and her research team from Northern Arizona University and the University of Wisconsin, USA, demonstrate that plant genes can have strong effects on the... view more...

How plants manage calcium may reduce effects of acid rain
A new understanding of how plants manage their internal calcium levels could lead to modifying plants to avoid damage from acid rain. The pollutant disrupts calcium balance in plants by leaching significant amounts of the mineral from leaves as well as the agricultural and forest soils the plants live in. view more (2007-03-12)
