Images for Impact Recorded October 2016 Download a handout with links and other information here. About this Webinar: Whether you’re Tweeting or teaching, well-designed images increase the impact of your message. It’s easy to make high-quality images for use in science communication (whether social media, blogs, infographics, animations, teaching or research) simply using tools available […]
Frédéric Bouché, a postdoctoral research with Richard Amasino at the University of Wisconsin, recently caught our attention when he published a set of impressive visual abstracts to support his latest research papers. We invited him to share how and why he makes these images. -Editors When you work hard, and your scientific work is finally […]
Eucalypts are fast-growing trees increasingly exploited for pulp, paper, bioenergy and other wood-based products. Using genetics tools and a network-based data integration (NBDI) approach, Mizrachi et al. explore a segregating Eucalyptus hybrid population for genes and pathways underlying biomass / bioenergy traits. Their analysis produced an expression QTL (eQTL) map and molecular networks associated with […]
One 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 effector AvrHah1 produced by the pathogen Xanthomonas gardneri […]
Root-knot nematodes including Meloidogyne javanica are major agricultural pests. Previous studies have shown that biocontrol agents including species of the fungal genus Trichoderma interfere with root-knot nematode pathogenicity, directly through effects on the nematode, and indirectly through a stimulation of plant defenses (priming). Medeiros et al. investigated the mechanism of priming by Trichoderma atroviride, using […]
One of the big challenges of working with wheat, as compared to rice, is that the wheat we eat is polyploid; bread wheat (Triticum aestivum) is hexaploid (six copies of each gene) and pasta wheat (Triticum turgidum) is tetraploid (four copies each). Polyploidy makes forward genetics difficult; knocking out one gene rarely leads to phenotypic […]
Where do flowers come from? Their sudden appearance and rapid radiation was described as an “abominable mystery” by Charles Darwin. Ruelens et al. examine the genetic toolkit that underpins reproductive organ formation in gymnosperms to uncover the origins of flowers (which they pragmatically describe as “an assembly of protective, attractive and reproductive male and female […]
It’s been 20 years since the identification of BRI1, the first brassinosteroid (BR) receptor. Although many components of the BR signaling pathways have been identified, details continue to be revealed. Kang et al. examined the phenotype of a triple mutant, bri1 brl1 brl3, that lacks all three functional BR receptors. Root elongation and protophloem differentiation […]
Arabidopsis has three membrane-located, histidine-kinase cytokinin (CK) receptors (AHK2, 3, and 4). Loss-of-function mutants suggest that AHK2 and AHK3 function somewhat redundantly. To further explore the roles of these receptors, Bartrina and Jensen et al. isolated dominant gain-of-function mutants, repressor of cytokinin deficiency2 (rock2) and rock3. As expected, these GoF mutants show enhanced CK signaling […]
