Ecosystem restoration strengthens pollination network resilience and function ($)
Plant Science Research Weekly, Research0 Comments

How 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…

Convergence in the molecular basis of carnivory
Plant Science Research Weekly, ResearchCephalotus follicularis is a heterophyllous pitcher plant that makes two types of leaves, carnivorous and non-carnivorous. By growing plants at different temperatures, Fukushima et al. were able to get plants to produce one of the two leaf forms. They sequenced the plant’s genome and compared transcriptomes…

Rewiring carotenoid biosynthesis in plants using a viral vector
Plant Science Research Weekly, ResearchA healthy human diet should include phytonutrients such as carotenoids. Several approaches including classical breeding and transgenic plant production have been used to increase carotenoid abundance in plant tissues; challenges to these approaches include feedback controls, cell toxicity due to abnormally…

Orchidstra 2.0 – A transcriptomics resource for the orchid family ($)
Plant Science Research Weekly, ResearchThere are more than 25,000 species in the Orchidaceae, the orchid family. Chao et al. have updated and restructured the Orchidstra database, which now houses more than half-a million protein-coding genes from 18 species (12 genera and five subfamilies). Access and explore it at http://orchidstra2.abrc.sinica.edu.tw.…

MarpoDB: An open registry for Marchantia polymorpha genetic parts
Plant Science Research Weekly, ResearchMarchantia polymorpha (a liverwort) is a living relative of the earliest terrestrial plants. As it has a simple genome and morphology and is readily transformable, it provides a good platform for synthetic biology (see https://www.openplant.org/marchantia/). Delmans et al. have designed an “engineering-oriented”…

Protein degradation rate in Arabidopsis thaliana leaf growth and development
Plant Science Research Weekly, ResearchProtein synthesis is an energetically-demanding process, made even more so by the fact that many proteins have a short half-life and must be repeatedly synthesized and degraded. Using a 15N-labeling approach, Li et al. determined the in vivo half-life for more than 1200 Arabidopsis leaf proteins; these…

Contrasting phytochrome responses in wild plants
Plant Science Research Weekly, ResearchShade avoidance syndrome (SAS) is a growth pattern in which stem and petiole elongation is stimulated in plants exposed to vegetative shade, as revealed through a low ratio of red to far-red light perceived by phytochrome; red light is absorbed by chlorophyll, leading to a far-red enrichment in light…
