Mentoring Lessons from Plants (Pub. Philos. J.)

Everybody mentors, but usually without much training in how to be an effective mentor. I recommend that you have a look at Beronda Montgomery’s short article, “From Deficits to Possibilities: Mentoring Lessons from Plants on Cultivating Individual Growth through Environmental Assessment and Optimization.”…

Stepwise and independent origins of roots among land plants (Nature)

The Rhynie chert  (near the village of Rhynie, Scotland; chert is a type of sedimentary rock) is an important site for plant biologists as it holds some of earliest and best preserved land-plant fossils. Hetherington and Dolan examined more than 600 thin sections prepared from this site, specifically…

Phosphoinositides control the localization of HOPS subunits and vacuole fusion (PNAS)

The plant vacuole makes up to 90% of the cell volume and its dynamics are important for regulating growth, development and stomatal movement. Membrane fusion between the vacuole and the smaller vesicles is at the heart of central vacuole establishment. Homotypic fusion and vacuole protein sorting…

Plant iron acquisition strategy exploited by an insect herbivore ($) (Science)

When it comes to evading pests and pathogens, stealth comes in handy. Anything that advertises “food here” is an invitation. Therefore, the work of Hu et al. shouldn’t be surprising, but it is a great story. Phytosiderophores such as benzoxazinoid are secreted by roots to chelate iron and facilitate…

Chloroplast TOC/TIC protein translocon pore size ($) (Plant Cell)

Most of the proteins that function inside of mitochondria or chloroplasts are encoded in the nucleus, translated in the cytosol, and imported through one or two membrane-localized translocons. (In mitochondria the outer- and inner-membrane translocons are called TOM and TIM, and in chloroplasts they…

The transcriptional landscape of polyploid wheat ($) (Science)

Wheat is a tough nut to crack, as it is hexaploid, comprising three diploid genomes (the A, B and D genomes). The International Wheat Genome Sequencing Consortium has released a fully-annotated wheat reference genome, and Ramírez-González et al. present a thorough analysis of its transcriptome. Although…

Review: X-ray fluorescence microscopy imaging (Plant Physiol.)

Kopittke et al. review the use of synchrotron-based X-ray fluorescence microscopy as a tool to quantify and localize diverse elements in plants. The authors describe how this method can be used to study nutrients in plants and human foods, as well as metal hyperaccumulating plants, and toxic metal(oid)…

Evolution and diversification of the plant gibberellin receptor GID1 (PNAS)

Giberellins (GA) are plant hormones that have diverse role in plant growth and development. Although many GAs have been identified, only few of them show functional activity in plants. GAs are perceived by the GID1 receptor, which is widespread in vascular plants and structuraly similar to carboxylesterases…
