We typically think of plants strutting their best stuff aboveground: showy flowers, fragrant blossoms, and unique shapes abound. But their development belowground is equally magical. In a new study, a team of international scientists, dug deep to better understand one of the most extraordinary root systems in the world.
Wildfires are devastating, but they can also bring new life by clearing existing vegetation and allowing new plants to spring up. Many plants in fire-prone areas actually require exposure to fire for seeds to germinate. In the past decade, scientists have discovered an ancient receptor protein that can detect molecules called karrikins in smoke from burnt plant material. The “smoke detector” protein, called KAI2, initiates molecular signals that speed up germination of seeds.
Whether Guard Cells (GCs) carry out photosynthesis has been debated for decades. Earlier studies suggested that guard cell chloroplasts (GCCs) cannot fix CO2 but later studies argued otherwise. Until recently, it has remained controversial whether GCCs and/or GC photosynthesis play a direct role in stomatal movements.
Study illustrates trade-off between plant regeneration and defense, offers strategies for enhancing regeneration in agriculture.
More extense use of existing genetically modified crops in Europe could reduce greenhouse gas emissions.
Weeds, the world’s most unwanted plants, might help trees make more fruit.
Researchers examine the formation of air channels in wetland plants, a protective trait that makes them resilient to environmental stresses.
Scientists are learning how to peer back through millennia of domestication to learn how a wild grassy plant known as teosinte developed into corn, the modern cash crop grown across the globe. The research allows scientists to compare genes in corn against its wild ancestor, which could help plant breeders identify advantageous traits that may have been bred out of teosinte over the centuries.
Live imaging of microbes in soil would help scientists understand how soil microbial processes occur on the scale of micrometers, where microbial cells interact with minerals, organic matter, plant roots and other microorganisms. Because the soil environment is both heterogeneous and dynamic, these interactions may vary substantially within a small area and over short timescales.
A new study involving more than 100 scientists from across the globe and the largest forest database yet assembled estimates that there are about 73,000 tree species on Earth, including about 9,200 species yet to be discovered.
