The University of Cincinnati and Spring Grove Cemetery & Arboretum replaced invasive and nonnative ground cover on E. Lucy Braun's grave with native plants as a tribute to the pioneering botanist and conservationist.
Like humans, plants protect themselves against pathogens. An international consortium under the lead of UZH professor Cyril Zipfel has now identified a long sought-after factor of this plant immune system: The calcium channel triggers the closure of stomata upon contact with microbes such as bacteria. This innate defense mechanism could help to engineer crop plants that are resistant to pathogens.
A new study by an international team including University of Maryland scientists has discovered the key calcium channel responsible for closing plant pores as an immune response to pathogen exposure. The findings are a major step toward understanding the defense mechanisms plants use to resist infection, which could eventually lead to healthier, more resistant and more productive crops.
Rice stems lengthen when a newly identified gene activates during flooding. Another gene suppresses lengthening in shorter varieties. The insight could help plant breeders.
Researchers analyze bean root architecture for better crop breeding
A study published today (Aug. 25, 2020) in eLife provides the first-ever, atomic-level, 3D structure of the largest protein complex (complex I) involved in the plant mitochondrial electron transport chain. The results could unlock new advances in agriculture.
X-ray images show a plant's power source may be different than thought.
In a paper published in Plants, People, Planet, The Morton Arboretum scientists Murphy Westwood, Ph.D., and Nicole Cavender, Ph.D., in collaboration with Abby Meyer, and Paul Smith, Ph.D., from Botanic Gardens Conservation International (BGCI), detail how botanical gardens have the skills and knowledge, facilities, plant collections, and access to the public required to advance plant conservation, but lack the funding and public recognition necessary to achieve significant impact on global conservation.
Researchers from the University of Tsukuba have found in a comparison of melon genomes that retrotransposons (a.k.a. "jumping sequences") may affect gene expression. Fruit ripening physiology varies widely in melons, and retrotransposons may have contributed to changes in gene expression as melon genomes diversified. Some retrotransposon sequences were transcriptionally induced under heat stress, suggesting that retrotransposons were responsive to this kind of stress, and may affect the expression of genes that induces fruit ripening.
Clinging to the walls of tropical caves is a type of plant with a single leaf that continues to grow larger for as long as the plant survives. Researchers at the University of Tokyo hope that their study of this unusual species may help inspire future genetic tools to control the size of common crop plants.
