Farmers' first line of defence against pests is the ecosystem in and around their fields, write Jonathan Lundgren & Scott Fausti. With widespread or indiscriminate use of pesticides essential biodiversity is lost - and the result is more frequent and serious infestations, and a decline in food security.
Genetic differences between hemp and marijuana determine whether Cannabis plants have the potential for psychoactivity, a new study by University of Minnesota scientists shows. The study was published in the July 17 online edition of New Phytologist.
Leaves are among the most abundant organs on earth and are a defining feature of most terrestrial ecosystems. However, a leaf is also a potential meal for a hungry animal and the question therefore arises, why does so much foliage survive in nature? What mechanisms protect leaves so that, on a global scale, only a relatively small proportion of living leaf material is consumed? Leaf survival is in large part due to two processes: firstly, leaf-eating organisms fall prey to predators (top-down pressure on the herbivore); secondly, leaves defend themselves (bottom-up pressure on the herbivore). Remarkably, these two types of event are often linked; they are controlled and coordinated by plants and the molecular mechanisms that underlie this are now beginning to emerge.
This novel text focuses exclusively on the leaf, on the herbivorous organisms that attack leaves, and the mechanisms that plants use to defend these vital organs. It begins with an assessment of the scale of herbivory, before examining direct physical and chemical defences on leaf surfaces and within the leaf itself. Although some leaf defences are easily seen, most operate at the molecular level and are therefore invisible to the naked eye. Many of these recently elucidated mechanisms are described. Throughout the book, perspectives from both the laboratory and the field are combined. A central feature of the work is its emphasis on the coevolution of leaf defences and the digestive tracts of animals including humans, making the book of relevance in understanding the role of leaf defences in agriculture.
Leaf Defence is suitable for senior undergraduate and graduate students taking courses in plant science, as well as a broader audience of biologists and biochemists seeking a comprehensive and authoritative overview of this exciting and emerging topic.

No tree is an island, and no place is this truer than the forest. Hidden beneath the soil of the forest understory is a labyrinth of fungal connections between tree roots that scientists call the mycorrhizal network.
"It's complicated": The convoluted family tree of wheat. AA = T. urartu, BB = Ae. speltoides, and DD = Ae. tauschii. AABB = emmer/durum wheat (T. turgidum), and AABBDD= modern bread wheat, T. aestivum. The first speciation event is homoploid hybrid, the second two are polyploid (as seen by chromosome copy increase). Images show extant wheat closely related to respective species. The circ
I used to love pine nuts, but now I’m wary of them. A couple years ago I threw a handful of them on a salad and they ruined my sense of taste for weeks. Water tasted bitter and metallic. Everything I ate tasted different, and not in a good way. Eventually, the bad taste went…
