Known degradation pathways are not involved in chloroplast turnover but are required for damage and starvation responses. Plant cells use an unknown mechanism to mark damaged chloroplasts for destruction, biologists have discovered.
Researchers know how to make precise genetic changes within the genomes of crops, but the transformed cells often refuse to grow into plants. One team has devised a new solution.
Tropical forests may be more resilient to predicted temperature increases under global climate change than previously thought, a study published suggests. The results could help make climate prediction models more accurate, according to the authors.
Planting Parasites: Unveiling Common Molecular Mechanisms of Parasitism and Grafting. β-1,4-glucanase, a cell wall degrading enzyme, is integral for plant parasitism and cross-species grafting in the plant family Orobanchaceae.
Researchers identify a unique version of a photosynthetic enzyme that has been in use for billions of years. A team of scientists has discovered an ancient form of rubisco, the most abundant enzyme on Earth and critical to life as we know it. Found in previously unknown environmental microbes, the newly identified rubisco provides insight into the evolution of the photosynthetic organisms that underlie the planet’s food chains.
Researchers generated genome sequences for nearly 600 green millet plants and released a very high quality reference S. viridis genome sequence. Analysis of these plant genome sequences also led researchers to identify a gene related to seed dispersal in wild populations for the first time.
From pollen forecasting, honey analysis and climate-related changes in plant-pollinator interactions, analysing pollen plays an important role in many areas of research. Microscopy is still the gold standard, but it is very time consuming and requires considerable expertise. Scientists have now developed a method that allows them to efficiently automate the process of pollen analysis.
Deprived of sunlight, plants are unable to transform carbon dioxide from the atmosphere into sugars. They are essentially starved of one of their most important building blocks. The plant’s not-so-secret weapon to combat this and other scarcity is autophagy. Similar to recycling, autophagy helps break down damaged or unwanted pieces of a cell, so that building blocks can be used again. New research shows that plants that lack the core components for autophagy have to get creative about recycling nutrients like carbon when they’re left in the dark.
Drought causes major crop losses in many regions of the world, and climate change threatens to exacerbate the occurrence of drought in temperate as well as arid regions. Researchers used a sophisticated mathematical modelling approach to study the effects of introducing CAM photosynthesis, which is used by plants that are able to thrive in arid conditions, into C3 plants, which tend to thrive only in areas where sunlight intensity and temperatures are moderate and water is plentiful.
Genome duplications play a major role in the development of forms and structures of plant organisms and their changes across long periods of evolution. Biologists made this discovery in their research of the Brassicaceae family. To determine the scope of the different variations over 30 million years, they analysed all 4,000 species of this plant family and investigated at the genus level their morphological diversity with respect to all their characteristic traits.
