Expert View. Merging genotypes: Scion/rootstock interactions (J Exp Bot)

Grafting is an ancient technology and still extremely important in horticulture and food production, including grapes for wine. Although much is known about what scion/shoot combinations work, less is known at the molecular and cellular level about successful grafts. How do two genetically different…

Review: Perspective on wheat yield and quality with reduced N supply (TIPS)

Wheat production demands huge inputs of nitrogen as fertilizer, with accompanying financial and environmental costs. Zorb et al. discuss several strategies by which to maintain wheat yields and wheat quality while decreasing N use and wastage. Some of these are agronomic, such as ensuring that the N…

Brassica clubroot disease protist pathogen promotes phloem differentiation and expression of SWEET sucrose transporters (Plant Cell)

Clubroot is a disease of brassicas (including oilseed crops and Arabidopsis) caused by the protist Plasmodiophora brassicae. The infection is characterized by the formation of swollen tissues called galls that are metabolic sinks in which the pathogen propagates. Walerowski et al. took advantage of Arabidopsis…

How Peroxisomes Modulate Chloroplast Activity in a Microalga

Background: Chloroplasts are the major powerhouse of plant and algal cells, where photosynthesis—the conversion of carbon dioxide into organic compounds using sunlight energy—occurs. Chloroplasts are also where important cell components (such as membrane lipids and pigments) and energy-rich compounds…

Genetic Basis of Natural Variation of Rice Ionomics

(Translated from the Chinese  original http://news.hzau.edu.cn/2018/1101/52991.shtml) Nanhu News Network (Correspondent Sheng Ke) On October 30th, the research group of Professor Tian Xingming from the Rice Science Team of the National Key Laboratory of Crop Genetic Improvement of our School…

NRT1.1 involved in balance between NH4+ uptake and assimilation ($) (Plant Physiol)

Ammonium (NH4+) is an inorganic nitrogen source that is the preferred source for some plant species (e.g., rice and tea) but can be toxic in high amounts. The nitrate transporter NRT1.1 is involved in mediating the effects of toxic NH4+, as well as functioning in NO3- and auxin transport, NO3- signaling…

Special Issue: Long-distance signaling ($) (Plant Cell Physiol)

Of course plants need to communicate between their different parts, and our understanding of these crucial signals has been advancing rapidly. This issue of Plant Cell Physiology includes a set of papers highlighting recent findings. A meeting report by Kiba on the Integrative Graduate Education and…

Systemic upregulation of Zn partitioning to the shoot supplements local Zn-deficiency responses (Plant Cell)

Zinc is an important micronutrient for plants and people. To better understand Zn uptake and homeostasis, Sinclair et al. used a transcriptomic approach to identify genes abnormally expressed in zinc-transporter mutants (hma2 hma4). In these mutants, Zn accumulates in roots but isn’t effectively transported…

Don’t Go Grocery Shopping When Hungry! Systemic Signaling in Zinc Homeostasis

Going grocery-shopping on an empty stomach is a bad idea. You’re bound to make poor decisions, not based on nutritional content of the food but based on temporary cravings that will leave you asking for more later. Plants face this nutritional puzzle every day, since they eat where they shop, and shop…
