How do plants protect themselves against sunburn?
To protect themselves against UV-B, which are highly harmful, plants have developed cellular tools to detect them and build biochemical defenses. A team of Swiss biologists discovered the existence of a UV-B receptor a few years ago. Today, these researchers demonstrate how these receptors, once activated by UV-B, associate with proteins that assist them to be assembled in the cell nucleus and to develop responses for survival and acclimation.

Gene blocking lettuce germination also regulates flowering time
This study of lettuce and Arabidopsis shows for the first time that a gene known to direct the depth of seed dormancy and the timing of germination also influences flowering. The findings also suggest that the gene does this by influencing production of certain microRNAs -- tiny snippets of genetic material that govern transition from one phase of the plant's life cycle to another.

Migratory birds disperse seeds long distances
Some species of plants are capable of colonizing new habitats thanks to birds that transport their seeds in their plumage or digestive tract. Until recently it was known that birds could do this over short distances, but a new study shows that they are also capable of dispersing them over more than 300 kilometers. For researchers, this function could be key in the face of climate change, allowing the survival of many species. (2016-03-22)

Antibiotics pave way for C. diff infections by killing bile acid-altering bacteria
New research finds that bile acids which are altered by bacteria normally living in the large intestine inhibit the growth of Clostridium difficile, or C. diff. (2016-01-06)

A wax shield to conquer the Earth
Researchers at the University of Geneva have discovered the cuticle. Present as a thick waxy layer in the seed coat and composed of cutin, the cuticle increases seeds' viability, their resistance to reactive oxygen species, and contributes to maintaining their dormant state. Seeds have thus recycled an ancient terrestrial plant protection mechanism that allows their leaves to be covered with an impermeable film preventing excessive transpiration. The results are published in the journal PLOS Genetics. (2015-12-17)

Preserved embryos illustrate seed dormancy in early angiosperms
The discovery of exceptionally well-preserved, tiny fossil seeds dating back to the Early Cretaceous corroborates that flowering plants were small opportunistic colonizers at that time, according to a new Yale-led study. (2015-12-16)

Increasing production of seed oils
Researchers in Japan have succeeded in inducing the genes involved in oil synthesis in seeds to work for longer periods of time, thereby allowing them to accumulate more seed oil. Their results have been reported online in the Plant Biotechnology Journal on Oct. 26, 2015. (2015-11-09)

Seaweed extract benefits petunia, tomato transplants
A study investigated the effects of two seaweed extract application methods (foliar spray or substrate drench) and rate on growth and postharvest drought tolerance of petunia and tomato transplants. Foliar sprays significantly affected growth of petunia and tomato, but did not improve drought tolerance of either. Applications of substrate drenches were recommended for improving postharvest life of petunia and tomato transplants, and foliar applications were recommended to increase plant growth. (2015-10-28)

Study reveals answers for managing Guam's threatened native trees
Researchers studied seedling emergence and growth traits of three rare and threatened tree species in the Mariana Islands to determine the influences of light and storage on seed and seedling behavior. Findings revealed that highly contrasting responses among the species provide a valuable start to building the knowledge base needed to respond to formal recovery or conservation plans by defining horticultural protocols for managing a conservation nursery. (2015-09-29)

Four fairies watch over Sleeping Beauty
Seed germination is a crucial step in the life cycle of a plant. This is why the small embryo is maintained in a state of dormancy until the appearance of optimal environmental conditions. The quality of its sleep is insured by the envelope of the seed, continuously producing a hormone named ABA. A study reveals how the transport of the hormone to the embryo is controlled. (2015-09-03)

An ounce of prevention: Research advances on 'scourge' of transplant wards
The fungus Cryptococcus causes meningitis, a brain disease that kills about 1 million people each year. It's difficult to treat because fungi are genetically quite similar to humans, so compounds that affect fungi tend to have toxic side effects for patients. Now, researchers at the University of Wisconsin-Madison have identified 18 proteins that play a role in spore formation and germination. (2015-08-27)

Green light of hope to overcome Striga-triggered food insecurity in Africa
Striga, a parasitic plant known as witchweed has seriously affected millions of hectares of crop fields in Africa that poses a major threat to food security. In a new study reported in Science, scientists have developed a new visualizing molecule to examine the process of Striga germination. The outcome of this study is expected to accelerate research to control Striga growth and to save crop losses worth of billions of US dollars every year. (2015-08-21)

Plant growth requires teamwork between 2 hormones
Two growth-promoting groups of substances, or phytohormones, the gibberellins and the brassinosteroids, are used independently of each other for the breeding and production of crop plants. A team of scientists at Technical University of Munich has now discovered that the two act in concert -- without brassinosteroids, a plant is unable to produce gibberellins. (2015-08-17)

Research charts a course for increasing edamame acreage in the Midwest
There have been limitations to growing edamame in the US Midwest, including little research on the cultivars that could be used here and how to grow the crop sustainably. But interest among US vegetable processors in edamame prompted researchers at the University of Illinois to take a closer look at the differences in growth and development between grain-type soybean and edamame, with the intent to identify specific improvements needed to grow more edamame in the Midwest. (2015-05-05)

Rare dune plants thrive on disturbance
A demographic study of two endangered plants at Point Reyes National Seashore north of San Francisco shows that they favor recently disturbed open areas over areas that have established plant cover. The study strengthens the case for removing the beachgrass originally planted to stabilize the dunes and allowing the sand to move in response to storm surges and strong tides. (2015-04-27)

Seeding mixtures recommended for midwest lawns
A study evaluated the establishment rate and species composition over 3 years of a turf stand seeded with different ratios of kentucky bluegrass and perennial ryegrass maintained as a lawn. The authors recommended seeding with a higher proportion (greater than 50 percent) of perennial rye grass in the Midwest to speed initial lawn establishment, control erosion, and/or to offset years with high weed pressure. (2015-03-09)

Seeds out of season
Past research has examined how environmental and genetic factors affect plant life stages individually, but a new study models how the three stages (seed, vegetative, and reproductive) interact with each other. (2015-01-05)

Colorado River Delta greener after engineered pulse of water
The engineered spring flood that brought water to previously dry reaches of the lower Colorado River and its delta resulted in greener vegetation, the germination of new vegetation along the river and a temporary rise in the water table, according to new results from the binational team of scientists studying the water's effects. The team's latest findings will be presented at the American Geophysical Union's annual meeting the afternoon of Dec. 18. (2014-12-17)

Seed dormancy, a property that prevents germination, already existed 360 million years ago
An international team of scientists, coordinated by a researcher from the U. of Granada, has found that seed dormancy (a property that prevents germination under non-favourable conditions) was a feature already present in the first seeds, 360 million years ago. Seed dormancy is a phenomenon that has intrigued naturalists for decades, since it conditions the dynamics of natural vegetation and agricultural cycles. There are several types of dormancy, and some of them are modulated by environmental conditions in more subtle ways than others. (2014-11-19)

Unusual host preference of a moth species could be useful for biological control
A team of Iranian researchers from the Rice Research Institute of Iran have discovered that Gynnodomorpha permixtana, a well-known moth species from Europe and Asia, has changed its host preferences in order to adjust to Iran's northern region environmental conditions. The importance of this adaptation for biological control of problematic weeds in rice fields and the biology of the host have been described in the open-access journal Nota Lepidopterologica.

Plants with dormant seeds give rise to more species
Seeds that sprout as soon as they're planted may be good news for a garden. But in the wild, a plant whose seeds sprouted at the first warm spell or rainy day would risk disaster. More than just an insurance policy against late frosts or unexpected dry spells, it turns out that seed dormancy has long-term advantages too: plants whose seeds put off sprouting until conditions are more certain give rise to more species. (2014-04-18)

Smoke in the water: Understanding the effects of smoke compounds on seed germination
Wildfires, although seemingly destructive, play an important role in plant ecosystems. In ecosystems where it occurs regularly, exposure to fire may initiate seed germination or enhance plant growth. Compounds released as plant tissue burns can break seed dormancy and stimulate germination. In the March issue of Applications in Plant Sciences, an efficient system to produce smoke solutions is described to aid investigation of the role of smoke compounds in seed germination and seedling growth. (2014-02-28)

A plant which acclimatizes with no exterior influence
Plants have a love-hate relationship with sunlight. While some wavelengths are indispensable to them for performing photosynthesis, others, such as UV-B, are deleterious. Therefore, plants are equipped to detect these highly toxic rays and mount their defences. A team led by Roman Ulm, Professor at the Faculty of Sciences at the University of Geneva, Switzerland, has generated a transgenic plant which acclimatises constitutively, regardless of the level of UV-B. (2013-11-25)

Researchers test effects of LEDs on leaf lettuce
Scientists determined the effects of blue and red LED ratios on leaf shape, plant growth, and the accumulation of antioxidant phenolic compounds of a red leaf lettuce and a green leaf lettuce cultivar. They determined that red LED light promoted growth and that blue LED light was good for phenolics accumulation rather than growth, thus concluding that a combination of red and blue light is essential for cultivation of leafy vegetables like lettuce.
