In Jezero Crater’s Bright Angel formation, Perseverance has found rocks rich in organic molecules and minerals linked to microbial metabolism. Their arrangement hints at redox reactions that resemble Earth’s life-driven chemistry. While not proof of Martian life, the findings qualify as “potential biosignatures” and make the stored sample a top candidate for return to Earth.
Read moreAluminum toxicity is a major contributor to poor crop growth, especially in regions with acidic soils. How aluminum enters at the growing root tips of plants is not well understood. Researchers have found that pectin, a chemical component of the plant cell wall, may play a key role as a barrier to prevent aluminum from entering rice plants. The study sheds light on how rice plants may resist aluminum toxicity.
Read moreThe roots of plants can do a lot of things: They grow in length to reach water, they can bend to circumvent stones, and they form fine root hairs enabling them to absorb more nutrients from the soil. A team of researchers has now identified an important regulator of this process.
Read moreIn an industry struggling to maintain profitability, it's curious that U.S. processing sweet corn – the corn that ends up in cans and freezer bags – is falling so far below its potential. Yet, that's what a new study clearly demonstrates.
Read moreA lack of tree seedling establishment following recent wildfires represents a crucial bottleneck limiting coniferous forest recovery in the western US, new research finds.
Read moreA team led by biologists have identified the ways in which herbicide-resistant strains of the invasive common waterhemp weed have emerged in fields of soy and corn in southwestern Ontario. The resistance, first detected in 2010, spread thanks to two mechanisms: either pollen and seeds of resistant plants were physically dispersed by wind, water and other means, or resistance appeared through the spontaneous emergence of mutations that then spread.
Read moreA new study finds that a unique mechanism involving calcium, the plant hormone auxin and a calcium-binding protein is responsible for regulating plant growth.
