A phase I clinical trial investigating the use of bacterial Clostridium novyi-NT spores as an injectable monotherapy had manageable toxicities and showed early clinical efficacy in patients with treatment-refractory solid tumor malignancies, according to data presented at the Fourth CRI-CIMT-EATI-AACR International Cancer Immunotherapy Conference: Translating Science into Survival, held Sept. 30-Oct. 3. (2018-09-30)

Seeing the light: Scientists unlock seed germination process
Scientists have identified a key gene that helps seeds decide whether to germinate. The MFT gene stops seeds germinating in the dark or under shady conditions, where their chances of survival would be poor, according to new research from the University of York. (2018-08-07)

When the seed becomes a plant, it has 48 hours to survive
During germination, the embryo within the seed must develop into a young seedling capable of photosynthesis in less than 48 hours. During this time, it relies solely on its internal reserves, which are quickly consumed. It must therefore rapidly create functional chloroplasts, cellular organelles that will enable it to produce sugars to ensure its survival. Researchers from the universities of Geneva and Neuchâtel, Switzerland, have revealed the key elements that control this process. (2018-08-02)

Taking the lead toward witchweed control

Hydrogen peroxide assists sexual reproduction in spruce
Plant physiologists from MSU proved for the first time that dangerous reactive oxygen species that are often considered as by-products of energy generation in cells, are required by the conifers to fertilize the egg cell. Experiments with pollen of blue spruce (Picea pungens) helped to find a protein that makes the whole system work. The scientists believe that the obtained data will lead to the optimization of conifer forests restoration. (2018-05-16)

Protect forest elephants to conserve ecosystems, not DNA
New University of Illinois research has found that forest elephant populations across Central Africa are genetically quite similar to one another. Conserving this critically endangered species across its range is crucial to preserving local plant diversity in Central and West African Afrotropical forests--meaning conservationists could save many species by protecting one. (2018-04-25)

Hunting is changing forests, but not as expected
In many tropical forests, over-hunting is diminishing the populations of animals who are vital for dispersing the seeds of woody plants. Those same plants are vital for carbon storage and previous theoretical modeling studies predicted dire consequences to defaunation, this research suggests otherwise. Instead the data shows the effects on the ecosystem are less straightforward and less immediately devastating. (2018-02-15)

Snacking snakes act as 'ecosystem engineers' in seed dispersal
Despite the bad rap snakes often get, they are more central to ecology than most people realize. New research reveals that snakes might even play a key role in dispersing plant seeds. (2018-02-08)

How plants see light
The proteins PCH1 and PCHL help plants adapt to their surroundings. (2018-01-23)

A classic Darwinian ecological hypothesis holds up -- with a twist
New University of Colorado Boulder-led research shows that a long-held hypothesis about the factors that govern species ranges largely holds true, but may be the result of a previously underappreciated ecological mechanism. (2017-12-25)

Vitamin E discovery in maize could lead to more nutritious crop
New research has identified genes that control vitamin E content in maize grain, a finding that could lead to improving the nutritional profile of this staple crop. Cornell University scientists and colleagues from other institutions combined different types of genetic association analyses to identify 14 genes across the genome that were involved in the synthesis of vitamin E. Six genes were newly discovered to encode proteins that contribute to a class of antioxidant compounds called tocochromanols, collectively known as vitamin E. (2017-11-01)

Tropical diversity takes root in relationships between fungi and seeds
A team led by Smithsonian scientists in Panama exposed a key to understanding tropical tree diversity by studying how fungi interact with seeds that linger in the ground. Despite a smorgasbord of species available to choose from, tropical fungi and seeds are picky about associating with one another. Early pairings with a particular fungus may influence whether a seed survives and also may help explain how tropical forests remain so diverse. (2017-10-02)

Development of an artificial orchid cultivation kit
Orchids are loved by gardeners around the world but are notoriously difficult to cultivate. Researchers have developed a new orchid cultivation kit and have succeeded in complete artificial cultivation of an autonomous orchid. Since this kit can be made cheaply, it can broaden the opportunities for orchid cultivation in general households. It is also expected to be useful in preserving the genetic diversity of orchidaceous plants, many of which are in danger of extinction. (2017-09-21)

Immune cells halt fungal infection by triggering spore suicide
To protect the body from infection, immune cells in the lungs can exploit cell death programs in inhaled fungal pathogens, scientists have revealed, helping explain why most people aren't harmed by breathing in mold spores, and potentially offering new therapeutic strategies for people who do get infected. (2017-09-07)

Tree-of-heaven's prolific seed production adds to its invasive potential
Tree-of-heaven -- or Ailanthus -- is an invasive triple threat, according to a team of plant pathologists. The species produces seeds early in its lifespan, tends to make millions of viable seeds during its life, and continues to produce seeds for decades and, in some cases, for more than a century. (2017-08-02)

Symbiosis: Butter for my honey
Textbooks tell us that, in arbuscular mycorrhizal symbioses, the host plant supplies its fungal symbionts solely with sugars, in return for inorganic nutrients. New findings by Ludwig-Maximilians-Universitaet (LMU) in Munich researchers now show that lipids are also on the menu. (2017-07-25)

Could calcium hold the key to fighting a dangerous hospital infection?
It lurks in hospitals and nursing homes, preying upon patients already weak from disease or advanced age. It kills nearly 30,000 Americans a year, and sickens half a million more. But new research shows that Clostridium difficile bacteria can't do all this without enough of a humble nutrient: calcium. And that new knowledge may lead to better treatment for the most vulnerable patients. (2017-07-13)

Scientists discover plant 'brain' controlling seed development
A new study by scientists at the University of Birmingham has revealed a group of cells that function as a 'brain' for plant embryos, capable of assessing environmental conditions and dictating when seeds will germinate. (2017-06-05)

Thirsty seeds reach for medicine cabinet

Nature plants a seed of engineering inspiration
Researchers in South Korea have quantitatively deconstructed what they describe as the 'ingenious mobility strategies' of seeds that self-burrow rotationally into soil. Seeds maneuvered to dig into soil using a coiled appendage, known as an awn, that responds to humidity. The team investigated this awn's burrowing and discovered how the nubile sprouts seem to mimic a drill to bury themselves. Their findings, published in Physics of Fluids, could have dramatic implications for improving agricultural robotics. (2017-04-24)

Study reveals listeria bacteria can hide inside tissue of romaine lettuce
A Purdue University study shows that the bacteria Listeria monocytogenes can live inside the tissue of romaine lettuce, suggesting that conventional post-harvest sanitization practices might not be sufficient to kill the potentially lethal pathogen. (2017-03-29)

Scientists follow seeds to solve ecological puzzle
A four-year study of one rare and one common lupine growing in coastal dunes showed that a native mouse steals most of the rare lupines seeds while they are still attached to the plant. The mouse is a 'subsidized species,' given cover for nocturnal forays by European beachgrass, originally planted to stabilize the dunes. (2017-03-21)

Vegetation resilient to salvage logging after severe wildfire
Nearly a decade after being logged, vegetation in forested areas severely burned by California's Cone Fire in 2002 was relatively similar to areas untouched by logging equipment. The findings of a US Forest Service study shed light on how vegetation responds to severe wildfire and whether further disturbances from logging affect regrowth. (2017-02-03)

Precut salad may encourage growth of Salmonella
A new study from the University of Leicester shows that small amounts of damage to salad leaves in bagged salads encourage the presence of Salmonella enterica. Juices released from damaged leaves also enhance the pathogen's ability to attach to the salad's plastic container. The research is published Nov. 18 in Applied and Environmental Microbiology, a journal of the American Society for Microbiology. (2016-11-18)

Dormancy relief, storage protocols for uhaloa seeds
A study determined physical dormancy and evaluated dormancy relief methods for uhaloa seeds. The greatest practical dormancy relief was achieved with a mechanical electric drum scarifier lined with 80-grit sandpaper for 15 or 30 seconds, producing 95 percent and 99 percent germination, respectively. Nonscarified seeds exhibited minimal loss of viability during 10 months of storage at 5 °C at 12 percent and 50 percent relative humidity, but a significant decline in viability of scarified seeds was detected. (2016-11-17)

Soy protein-based seed coating acts as biostimulant
Researchers developed a seed coating for broccoli seedlings using soy flour as a binder in a soy flour, cellulose, and diatomaceous earth coating formulation. Soy flour acted as a biostimulant to enhance plant growth and nitrogen uptake in the plants. Soy flour-coated seeds had greater seedling root and shoot growth, and when applied at 30 percent, 40 percent, and 50 percent, soy flour increased total nitrogen per plant compared with the noncoated control. (2016-11-14)

Scientists at MIPT beat the clock by quickly finding out what makes plants tick
Scientitsts from MIPT have developed a technique which can control the growth of plants. They decided to try pollen tubes, which compared to seeds germinate much more quickly (2 hours instead of weeks). Knowing the compounds that influence the rate of plants development will enable biotechnologists to selectively inhibit the growth of pests and promote the growth of crops. (2016-10-25)

Scientists trace plant hormone pathway back 450 million years
Purdue scientists got a glimpse into more than 450 million years of evolution by tracing the function of a hormone pathway that has been passed along and co-opted by new species since the first plants came onto land. (2016-10-24)

Triploid flowering pears reduce self-sowing
In analyses of 13 flowering pear triploids, relative female fertility was significantly reduced, ranging from 0.0% to 33.6%. Five accessions had a relative fertility of <2%. Cytometric analysis of seeds and seedlings from triploid maternal parents showed that they were predominantly abnormal aneuploids, typically resulting in seedlings with reduced fitness and fertility. The results indicate that selection of infertile cultivars can be a viable approach to reducing unwanted reseeding in flowering pear. (2016-10-19)

Seed coating effective on turfgrass under deficit irrigation
Researchers used low-dose applications of a surfactant film coating (SFC) in experiments with two species of turfgrass. Perennial ryegrass density, cover, and aboveground biomass from the SFC were ≈47%, 48%, and 46% greater than untreated seed, respectively. Tall fescue density, cover, and aboveground biomass from the SFC seeds were ≈22%, 23%, and 28% greater than untreated seed, respectively. The study demonstrated that SFC can promote seed germination and enhance turfgrass establishment under deficit irrigation. (2016-10-19)

How plants grow new lateral roots
Researchers have used 3-D live imaging to observe the formation process of lateral roots in plants, and clarified part of the mechanism that creates new meristematic tissue. If the root formation mechanism in plants is revealed further, this could potentially be used to control plant growth by artificially altering root system architecture. These findings were published on Aug. 10 in the online version of Development, and clips of the live imaging were selected as the Featured Movie of the current issue (Vol. 143/Issue 18). (2016-10-06)

Propagation protocols determined for 2 Nyssa species
Experiments with two Nyssa species showed that cold stratification enhanced speed and uniformity of germination of cleaned seeds of swamp tupelo. Seeds of swamp tupelo were found less resistant to germination when compared to seeds of black gum. Additionally, extracts of the fruit pulp of swamp tupelo were found to inhibit germination of seeds of swamp tupelo and other species. The experiments showed that swamp tupelo can be propagated reliably from seeds removed from fruits. (2016-08-29)
