Grasses transfer genes from their neighbours in the same way genetically modified crops are made, a new study has revealed.

As climate change progresses, the chance of southern plant species spreading to northern regions increases. In Europe and America, many of the alien plant species come from their own continent. They usually originate in warmer regions closer to the equator—a phenomenon that could be exacerbated by climate change.
For reasons of food security and economic incentive, farmers continuously seek to maximize their marketable crop yields. As plants grow inconsistently, at the time of harvesting, there will inevitably be variations in quality and size of individual crops. Finding the optimal time to harvest is therefore a priority for farmers. A new approach making heavy use of drones and artificial intelligence demonstrably improves this estimation by carefully and accurately analyzing individual crops to assess their likely growth characteristics.
Scientists have revealed new plant cell walls can have significantly different mechanical properties compared to surrounding parental cell walls, enabling cells to change their local shape and influence the growth of plant organs.
A chloroplast enzyme safeguards plants against pathological protein aggregation that causes Huntington’s and other neurodegenerative diseases / new research may have found a way to “copy” the mechanism for application in human cells.
Plants that rely on animal pollinators, such as insects or birds, have evolved distinctive suites of flower characteristics—known as “pollination syndromes”—that are tailored to the pollinator. Large differences in flower characteristics between wildflowers with different pollinators are achieved by a few key genetic differences, according to a new study.
Nitrogen is an essential nutrient for plant growth, but the overuse of synthetic nitrogen fertilizers in agriculture is not sustainable. In a review article a team of bacteriologists and plant scientists discuss the possibility of using genetic engineering to facilitate mutualistic relationships between plants and nitrogen-fixing microbes called “diazotrophs.” These engineered associations would help crops acquire nitrogen from the air by mimicking the mutualisms between legumes and nitrogen-fixing bacteria.
Lurking inside the crops of banana-producing-areas in east and central Africa is a disease called Banana Xanthomonas Wilt (BXW)—and new modeling has shown that if left uncontrolled, this bacterial disease could cause a 55% reduction in banana production in newly affected regions within 10 years.
In plants, the jasmonate (JA) signaling pathway helps plants control their defense responses to environmental stresses. Like the human body, plants respond differently to individual threats. Just as people wouldn’t get a fever due to a sprained ankle, plants deal with harmful elements in particular ways. A study looks at how plants respond to environmental threats in the correct way.
Imagine if humans could ‘talk’ to plants and warn them of approaching pest attacks or extreme weather. A team of plant scientists would like to turn this science fiction into reality using light-based messaging to ‘talk’ to plants
