Local plant-microbe alliances shape global biomes

Dense rainforests, maple-blanketed mountains and sweeping coniferous forests demonstrate the growth and proliferation of trees adapted to specific conditions. The regional dominance of tree species we see on the surface now, however, might actually have been determined underground long ago.…

Interplay of Pollinators and Pests Influences Plant Evolution

Brassica rapa plants pollinated by bumblebees evolve more attractive flowers. But this evolution is compromised if caterpillars attack the plant at the same time. With the bees pollinating them less effectively, the plants increasingly self-pollinate. In a greenhouse evolution experiment,…

Scientists crack the code to regenerate plant tissues

Plant regeneration can occur via formation of a mass of pluripotent cells. The process of acquisition of pluripotency involves silencing of genes to remove original tissue memory and priming for activation by external input. Led by Professor Sachihiro Matsunaga from…

Pollen Genes Mutate Naturally in Only Some Strains of Corn

Pollen genes mutate naturally in only some strains of corn, according to Rutgers-led research that helps explain the genetic instability in certain strains and may lead to better breeding of corn and other crops. Scientists at Rutgers University–New Brunswick and…

How plants defend themselves

Plant immune system detects bacteria through small fatty acid molecules. Like humans and animals, plants defend themselves against pathogens with the help of their immune system. But how do they activate their cellular defenses? Researchers at the Technical University of…

Getting to the root of plant simulations

New dynamic model better portrays how plant roots forage and adapt to resource fluctuation. If you’ve ever tended a garden or potted a plant, you know a few simple truths about green things — they require water and nutrients to…
