To compensate for their lack of a nervous system, vascular plants have developed complex mechanisms to connect their organs and coordinate stress. Many different types of molecules are involved in long-distance signaling and must be integrated to maintain homeostasis. In this review, Takahashi and Shinozaki…

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…

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…

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…

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…

(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…

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…

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…
