Plant cell walls are complex and somewhat difficult to study, but also idespensible for plants and central to many of the ways that people use plants (from wood to fibers to fuels). Two new articles review diverse aspects of plant cell wall synthesis. Polko and Kieber (Plant Cell 10.1105/tpc.18.00760 $) focus on the regulation of […]
Phenotypic plasticity, or the ability to change in response to the environment, is one of the most characteristic (and to me, endearing) qualities of plants. As Arnold et al. observe, it is also one of the most important in terms of future climate change; phenotypic plasticity will mean the difference between species that persist and […]
Writing is one of the most important of a scientist’s skills but often overlooked during their training. As Freeling et al. observe, good writing takes time, both to learn and to teach, so what’s the incentive? In this Opinion article, they make an effort to quantify the impact (measured by citation numbers) of “good writing”. […]
The vascular cambium is a meristematic tissue that is responsible for lateral growth and the continued production of new xylem and phloem; in woody plants, the shoot vascular cambium makes wood. A new pair of papers investigates how the Arabidopsis root vascular cambium forms and how it functions. Through mutant analysis and imaging, the authors […]
This is an interesting paper that touches on several topics. Bhatia et al. address the question of how polarity in leaves is first established: essentially, which comes first, polarity in auxin concentration or polarity in gene expression? The authors conclude that in the earliest leaf primordia, there is no gradient of auxin sensing (suggesting perhaps […]
Sunflower (Helianthus annuus L.) is an important oil-producing crop, which was domisticated in North America about 4000 years ago with elite varities being developed through the 19th and 20th centuries, narrowing its genetic variation. It retains the ability to hybridize with wild relatives, providing opportunities to introgress desirable traits. Hübner et al. sequenced and analyzed […]
Microbes that live in, on and near plants profoundly affect their growth and survival. Here, Bergelson et al. sequenced the bacterial and fungal microbiomes of Arabidopsis roots (previously they sequenced samples from leaves). The accessions are from all over the world but the sequenced samples are from a single field. Key take-aways are: don’t forget […]
Special Issue: Genome to Phenome (Plant Journal) It’s January, which seems to be a month of weather extremes for many “temperate” parts of the globe. Here’s an excellent collection to curl up with as you try to stay warm or cool and out of the elements. The issue includes free-to-access reviews focused on using genomic […]
Press release – translated from the original Article source: Microbiology Research Institute Published: 2019-01-23 Cotton Verticillium wilt is a soil-transmitted vascular bundle disease caused by Verticillium dahliae, which is the primary disease that restricts cotton production in China. It is the focus of the current cotton field research and application to discover the key disease resistance […]
