It's a difficult topic, but transparancy is always good. Here's an update on the ongoing investigations into several prominant plant science papers. .If you have a chance to discuss this topic with your students or lab group, the Office of Research Integrity (ORI; https://ori.hhs.gov/) has many useful educational resources, for example this tutorial on how to avoid inappropriate image manipulations http://ori.hhs.gov/educat…/products/RIandImages/default.html
These days I received an apparently easy request: “Do you have any recommendations for reading about the debate on GMOs? I think there is a lot of heat, but too little light in the discussion; I trust you can send me some…” To which I answered carelessly: “Sure, I will look into it, select a few references and post them…”
I thought I’d have a quick look into my collection of bookmarks and references and post some of the links to satisfy the request. Obviously there would be too many individual studies and crop-specific or country-specific reports, but focusing only (i) on what was published in recent years, (ii) on sources where all this information was already aggregated (literature reviews, meta-analyses, authoritative statements, FAQs, etc.), and (iii) on academic or publicly funded sources should produce a fairly concise list, I thought.
While not unmanageable, the list has become quite long. To get a rough idea of the current state of knowledge, it may be sufficient to peruse the first 1-2 (starred *) references under each heading, and to have a quick look at the abstracts and summaries of some of the others. (Given the controversy surrounding this topic I did not want to suggest just one or two sources, but show a bit the width of the scientific consensus, and to offer some titbits of related information.) ...
QTL COLD1 regulates G-protein signaling to confer chilling tolerance in rice •SNP2 in COLD1jap/ind enhances its ability to activate G-protein α GTPase •COLD1 interacts with G protein to activate the Ca2+ channel for temperature sensing •The SNP2-containing allele is selected during japonica rice domestication
I came across this expression over the weekend, and although I’m still not sure what it means, it made me wonder about other plant-based similes and metaphors. I did a little searching and found that at least in English, plant metaphors are pretty common (see link).
For example, “They were like two peas in a pod and their love blossomed until through the grapevine she learned of trouble and decided to get to the root of the problem.”
I'm curious though, are there plant metaphors that span many languages? Can you be "fresh as a daisy" in French? Is there a "thorny problem" in Thai? Can you "spill the beans" in Spanish?
Here's an extensive list in English from Garden Digest to help you green up your next writing task. http://www.gardendigest.com/cliche.htm I'd be happy to get a link to a similar list in other languages!
I worked too late last night and then dreamed I was playing Plant Nutrition-Opoly.....
Designing and playing games is a terrific way for students to learn. What would the Railroads be - ion transporters? What events would be described on the Chance cards - Mycorrhizal symbiosis, win $10?
For an introductory class, students could redesign the board using plant taxa... orchids for the high-rent squares?
In the budding field of article-level metrics, Altmetric has been leading the way in measuring the attention and impact of research papers beyond the archaic method of counting citations. Founder Euan Adie sheds light on the inadequacy of journal-level metrics, the future relationship between academia and Twitter, and the work that goes on behind the scenes at Altmetric
Using hundreds of samples of field-grown rice (Oryza sativa) leaves, we developed a statistical model for the expression of circadian clock-related genes integrating diurnally entrained circadian clock with phase setting by light, both responses to light and temperature gated by the circadian clock. We show that expression of individual genes was strongly affected by temperature. However, internal time estimated from expression of multiple genes, which may reflect transcriptional regulation of downstream genes, is punctual to 22 min and not affected by weather, daylength, or plant developmental age in the field. Thus, we demonstrated that the circadian clock is a regulatory network of multiple genes that retains accurate physical time of day by integrating the perturbations on individual genes under fluctuating environments in the field.
It's gardening week at Biodiversity Heritage Library, and they're featuring their collection of antique and historical seed catalogues. Maybe the prose is a bit over the top, but the drawings are stunning.
"We found that scientists are motivated in their work to find out more about the world and to benefit society, and that they believe collaboration, multidisciplinarity, openness and creativity are important for the production of high quality science. However, in some cases, our findings suggest, the culture of research in higher education institutions does not support or encourage these goals or activities. For example, high levels of competition and perceptions about how scientists are assessed for jobs and funding are reportedly contributing to a loss of creativity in science, less collaboration and poor research practices. The project led to suggestions for action for funding bodies, research institutions, publishers and editors, professional bodies and individual researchers. "
I can't help but think that this essay would be a good starting point when assigning university students the task of adapting a piece of scientific writing for the public. How do you keep the meaning and tone but make the text accessible?
"Watch a new video illustrating the devastating impacts that Tuta absoluta (tomato leafminer) is having on tomato yields, and what this means for farmers who rely on these crops for sustenance and income.
This Invasive Alien Species is rapidly moving down the African continent, having already decimated crops in Egypt, Ethiopia, Kenya and northern Tanzania. Growers are at their wits end as to how best they can control this pest and many have abandoned tomato growing altogether. The race is on to prevent its spread further south with various interventions planned to mitigate its impact in areas where it is already present."
Synbio was going to save the world. Now it’s being used to make vanilla flavoring.
Mary Williams's insight:
Definitely worth reading - good for classroom discussions too. Is a flavor molecule different if it's extracted from a plant, an engineered yeast or algae, or made entirely synthetically? How does the drop in oil prices affect biofuels research? What's the role of government in funding alternative energy sources? Is "synbio" a scary term for consumers, and if so what would be a better alternative?
Here, we show that DA1 and its close family members DAR1 and DAR2 are redundantly required for endoreduplication during leaf development. DA1, DAR1, and DAR2 physically interact with the transcription factors TCP14 and TCP15, which repress endoreduplication by directly regulating the expression of cell-cycle genes. We also show that DA1, DAR1, and DAR2 modulate the stability of TCP14 and TCP15 proteins in Arabidopsis thaliana.
