Plants produce a wide range of polysaccharides in their cell walls, some of which are restricted to certain species. Roberts et al. investigated a moss gene encoding an enzyme that resembles a mixed-linkage (1,3;1,4)-β-glucan (MLG) synthase. When expressed in tobacco, this enzyme produces a novel unbranched, unsubstituted arabinoglucan (AGlc) polysaccharide that consists of both glucose […]
Review: Venus Flytrap: How an excitable, carnivorous plant works The one sure-fire way to get children excited about plants is to show them how a Venus flytrap works. But how does it work? We’ve all heard that the trap “counts” the number times it is triggered, and that it requires two or more touches in […]
New work published in The Plant Cell is featured in this press release from the University of Adelaide. An international team of scientists including the University of Adelaide has discovered a new complex carbohydrate in moss that could possibly be exploited for health or other uses. The scientists, from Australia’s ARC Centre of Excellence in […]
An image from a paper published in Plant Cell is featured as The Scientists “Image of the Day” Image of the Day: Pseudomonas Autophagy Researchers identify antibacterial functions of cell death in Arabidopsis when the plant is infected with Pseudomonas. By The Scientist Staff | March 30, 2018 A plant cell (Arabidopsis) infected with Pseudomonas […]
In a new study published in The Plant Cell, a team of researchers identified a gene that limits yield losses in rice plants exposed to salt stress and deciphered the underlying mechanism. Soil salinity poses a major threat to food security, greatly reducing the yield of agricultural crops. Rising global temperatures are expected to accelerate […]
A new study published in The Plant Cell has isolated a gene controlling shape and size of spikelets in wheat. Materials provided by the John Innes Centre. A new study has isolated a gene controlling shape and size of spikelets in wheat in a breakthrough which could help breeders deliver yield increases in one of […]
Surprisingly little is known about the pathogens of liverworts. Carella et al. explored the interaction between the broad-host range pathogenic oomycete Phytophthora palmivora and the model liverwort Marchantia polymorpha. They found that the pathogen enters the host tissues and proliferates in intercellular air chambers between photosynthetic cells, and also forms intracellular hyphal structures and expresses […]
Stem rust is a fungal disease of wheat caused by Puccinia graminis f. sp. tritici (Pgt). The Ug99 race group of the fungus has evolved the ability to overcome most stem rust (Sr) resistance genes. Previously, Sr21, an Sr gene that confers partial resistance to Ug99, was found in diploid wheat. Chen et al. showed […]
A Commentary by Jaffé et al. introduces a New Phytologist Virtual Issue on the curious and fascinating plants that hyperaccumulate metals. These diverse species have shed light on metal transporter proteins and mechanisms of metal tolerance, on the ecological function of metal hyperaccumulation (possibly to deter herbivores, pathogens, or neighboring plants), and might even provide […]
