Oscillating aquaporin phosphorylations and 14-3-3 proteins mediate circadian regulation of leaf hydraulics (Plant Cell)

Plant activities change drastically between the light and dark times of day. Many of these different activities can be observed through transcriptional studies, which show that gene expression goes up and down over the course of the day. Many of these transcriptional changes are driven by the circadian…

Hydraulic Regulation of Stomata in Ferns

Stomatal responses to environmental and endogenous signals in vascular plants are critical for regulating plant gas exchange with the atmosphere. In addition, stomatal closure is vital for minimizing water loss and preventing lethal embolism during drought.  The vast majority of studies concerning stomatal…

Review: Long distance signlaing in plant stress response (COPB)

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…

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…
