Soil chemistry, not short-term deer exclusion, explains understory plant occupancy in Pennsylvania oak forests
A study of deer browsing has uncovered the contribution of soil chemistry to ‘the ghost of herbivory past’. More

Exploring the salt tolerance of the Nona Bokra rice landrace
Salt stress is a major limiting factor for crop production across the world. Rice is particularly sensitive to salinity, with both plant growth and grain yield significantly impaired under saline conditions. However, the ability to tolerate salt differs with the growth stages of the plant as well as varying across different varieties of rice. Some […] More

Unravelling the genetic makeup of hybrid meadow knapweed populations in North America
Hybridization is thought to be a primary trigger of plant invasions, due to short term hybrid vigour of early generations or increased evolutionary potential in later generations. Yet despite widespread appreciation of the link between hybridization and invasion, few studies have actually tested whether hybridization during invasion reflects short-term vs. advanced generations of introgression. One […] More

The defensive benefit and flower number cost of selenium accumulation in Brassica juncea
Selenium is an essential element for animal health, but it can be also be toxic in high concentrations. Plants are known to exploit this by storing high levels of selenium in their leaves and effectively poisoning herbivores and pathogens. Yet, there can be costs associated with accumulation of selenium in plant tissues, including oxidative stress […] More

The total dispersal kernel: a review and future directions
The distribution and abundance of plants across the world depends in part on their ability to move, which is commonly characterized by a dispersal kernel (a probability density function describing where seeds land relative to the parent plant). The total dispersal kernel (TDK) describes the combined influence of all primary, secondary, and higher-order dispersal vectors […] More

Accurate position exchange of stamen and stigma resolves the herkogamy dilemma in a protandrous plant, Ajuga decumbens (Labiatae)
Spatial separation of stamen and stigma (herkogamy) is an effective way for angiosperm species to reduce sexual interference and prevent self-pollination. It can however also reduce the possibility of pollinators contacting both sexual organs. For, example, pollen may be deposited on a site of the pollinator’s body that will not come into contact with the […] More

Domestication influences morphological and physiological responses to salinity in Brassica oleracea seedlings
Wild germplasm can potentially be used to improve the salt tolerance of crops by the identification of useful genes and incorporation of these into salinity-sensitive cultivars. More

Herkogamy and dichogamy in style dimorphic flowers of Narcissus broussonetii (Amaryllidaceae)
Across the plant kingdom, there is an extraordinary diversity of flower forms, many of which are related to variation in the morphology and arrangement of reproductive organs. To prevent self-pollination, plants have evolved floral forms where sexual organs are separated spatially (herkogamy) or temporarily (dichogamy) within a single hermaphrodite flower. Both mechanisms are widespread among […] More
