Hybrid agricultural and horticultural crops can play an important role in supporting global food security. They produce higher yields and are often more resistant than non-hybrid varieties to diseases and climate stress. But for many crops, no hybrid varieties are available. Why is that?
What will happen to the world’s forests in a warming world? Will increased atmospheric carbon dioxide help trees grow? Or will extremes in temperature and precipitation hold growth back? That all depends on whether tree growth is more limited by the amount of photosynthesis or by the environmental conditions that affect tree cell growth—a fundamental question in tree biology, and one for which the answer wasn’t well understood, until now.
The researchers have evaluated the impact of the effects of climate change on vital parameters of bean varieties, such as their morphology, reproduction, production, and phenology. Thus, they have detected some very sensitive types to variations in their conditions of origin. These others perform better with the increase in temperature, and others are highly resilient to any change.
A new study has discovered the functions of hundreds of genes in algae, some of which are also present in plants. The achievement will help efforts to genetically engineer algae for biofuel production and develop strains of agricultural crops that can withstand climate change.
Modifying photosynthesis has increasingly been a research target to improve crop yields to feed a growing global population in the face of climate change and other environmental factors. In a recent study, a research team investigated the effects of increasing the amount of carbon dioxide channels in plant membranes, but could not detect any impact on photosynthesis in model tobacco plants.
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.
