In contrast to previous assumptions, the defense hormones salicylic acid and jasmonic acid do not always suppress each other in regulating plant chemical defenses against pests and pathogens. In trees, the interplay of both hormones can actually increase plant resistance. This is the conclusion researchers draw in a new study on poplars.
Low-cost “tree fitbits” can pinpoint the precise timing of tree activities, like spring bloom or autumn leaf change, according to a new study. Researchers outfitted two ash trees with high-resolution accelerometers, efficiently tracking how the trees responded to changing seasons.
Researchers explore the functional significance of different types of two-pore channels in a liverwort, Marchantia polymorpha.
The absence of large herbivores after the extinction of the dinosaurs changed the evolution of plants. The 25 million years of large herbivore absence slowed down the evolution of new plant species. Defensive features such as spines regressed and fruit sizes increased.
Not all lentils are created equal. Lentil genetics can affect both the quality and yield of lentil crops. Environmental factors – like rainfall and soil conditions – can also impact lentil crops. Even the same lentil variety can have vastly different yields and nutritional profiles when grown in different environments.
When faced with conditions that are too dry, salty, or cold, most plants try to conserve resources. They send out fewer leaves and roots and close up their pores to hold in water. If circumstances don’t improve, they eventually die. But some plants, known as extremophytes, have evolved to handle harsh environments.
Research team investigates shifts in seasonal development of early-blooming forest plants – herbarium records show climate warming.
Flowering time in chickpeas’ wild relatives is influenced by one to three major genes, according to new research.
A protein that allows the fungus that causes white mold stem rot in more than 600 plant species to overcome plant defenses has been identified by a team of scientists.
Airborne pollen may induce annoying congestion for some, but a new paper shows that these grains may provide a new way of looking at the climate over 300 million years into the fossil record.
