Review: Mycorrhizal ecology and evolution: the past, present and the future
Plant Science Research Weekly, Research0 Comments
/
There are about 50,000 fungal species that form mycorrhizal associations with about 250,000 plant species. These associations significantly increase plant productivity by increasing nutrient uptake, particularly nitrogen and phosphorus, although with a considerable carbon cost to plants. Van der Heijden…
Review: Rapid long-distance signaling with Ca2+, ROS and electrical signals ($)
Plant Science Research Weekly, ResearchThere is ample evidence for rapid, long-distance communication within plants, but our understanding of how these signals are transmitted is incomplete. Choi et al. review recent advances in intercellular signal propagation via Ca2+, reactive oxygen species (ROS) and electrical signals; these “fast”…
New Phytologist Tansley Medal finalists essays
Plant Science Research Weekly, ResearchThe New Phytologist Tansley Medal is awarded to an early career scientist for excellence in plant science. The essays submitted by each of the five finalists are published in the March 2017 of New Phytologist, and make good reading. We agree with the sentiments of the editors, “warmest congratulations…
From LUCA to Lily: 12 perspectives for teaching about plants
Blog, Education, Resources, Resources, Undergraduate
The other day I was talking to a friend about the need to demystify plants, so that teachers feel as confident in their teaching of plant biology as they do about animal biology. I wonder if sometimes we teach plants too much in isolation, so it’s not always clear how plants relate to other organisms…
Ecosystem restoration strengthens pollination network resilience and function ($)
Plant Science Research Weekly, ResearchHow does ecosystem restoration affect ecosystem services such as pollination? Kaiser-Bunbury et al. analysed 64 plant-pollinator networks across four restored and four unrestored communities. Restoration involved the removal of all exotic plants (nearly 40,000 individuals). After restoration, over a…
Two clustered NLR genes with opposing functions in rice blast resistance and yield ($)
Plant Science Research Weekly, ResearchThe indigenous Chinese rice variety Gumei 4 (GM4) shows durable and specific resistance to the rice blast fungal pathogen Manaporthe oryzae. Deng et al. mapped and sequenced the resistance locus Pigm, and found that it contains a cluster of 13 NLR (nucleotide-binding leucine-rich repeat) genes, three…
Electrical and hormonal signals of prey capture in sundew ($)
Plant Science Research Weekly, ResearchWithout eyes, mouths or noses, how do carnivorous plants know that they’ve captured prey? Previous studies in various carnivorous species have shown that electrical signals as well as the jasmonate defense hormones contribute to prey detection. Krausko et al. examined these signals in leaves of the…
How can genomics help neglected crops fight disease?

I recently attended a Plant Pathology symposium on “Genomics Strategies for Developing Sustainable Disease Resistance for Neglected Crops…
A pectase lyase that is an indirect target of a Xanthomonas TAL effector promotes susceptibility
Plant Science Research Weekly, ResearchOne of the many ways that Xanthomonas bacteria manipulate their host plants is by the production of transcription activator-like (TAL) effectors, which the bacterium introduces into the host cell where they alter gene expression in the host nucleus. Schwartz et al. investigated the targets of the TAL…
