Post-diagnostic reliance on plant-compared with animal-based foods and all-cause mortality in omnivorous long-term colorectal cancer survivors.

Am J Clin Nutr 2021 May 8. Epub 2021 May 8.

Institute of Epidemiology, University Hospital Schleswig-Holstein, University of Kiel, Kiel, Germany.

Background: Plant-rich diets are associated with lower cardiometabolic risks and longer survival in the general population, but their association with mortality in cancer survivors is still unclear.

Evaluation of four field portable devices for the rapid detection of mitragynine in suspected kratom products.

J Pharm Biomed Anal 2021 Apr 30;201:114104. Epub 2021 Apr 30.

U.S. Food and Drug Administration, Forensic Chemistry Center, 6751 Steger Drive, Cincinnati, OH, 45237, USA. Electronic address:

The development of a method for the rapid screening of food and drug products for constituents such as mitragynine, the most abundant alkaloid found in Mitragyna speciosa (kratom) plant leaves, has become increasingly important. The use of kratom is said to produce stimulant or narcotic effects and poses risks of addiction, abuse, and dependence, much like other opioids. Direct Analysis in Real Time with thermal desorption mass spectrometry (DART-TD-MS), hand-held mass spectrometry, portable ion mobility spectrometry (IMS), and portable Fourier-transform infrared spectroscopy (FT-IR) were each evaluated as field-deployable screening techniques for the detection of mitragynine in food and drug products.

Functional overlap of two major facilitator superfamily transporter, ZIF1, and ZIFL1 in zinc and iron homeostasis.

Biochem Biophys Res Commun 2021 May 5;560:7-13. Epub 2021 May 5.

Department of Biological Sciences, Dartmouth College, Hanover, NH, 03755, USA.

Zinc and iron are essential micronutrients for plant growth, and their homeostasis must be tightly regulated. Previously, it has been shown that Zinc-Induced Facilitator 1 (ZIF1) is involved in basal Zn tolerance by controlling the vacuolar storage of nicotianamine (NA). However, knowledge of the functional roles of two ZIF1 paralogs, ZIF-LIKE1 (ZIFL1) and ZIFL2, in metal homeostasis remains limited. Read More

Institute of Plant Sciences Paris-Saclay, INRAE, CNRS, Université Paris-Saclay, Orsay 91405, France. Electronic address:

Fruit set is inhibited by adverse temperatures, with consequences on yield. We isolated a tomato mutant producing fruits under non-permissive hot temperatures and identified the causal gene as SlHB15A, belonging to class-III homeodomain leucine-zipper transcription factors (HD-ZipIII). SlHB15A loss-of-function mutants display aberrant ovule development that mimics transcriptional changes occurring in fertilized ovules and leads to parthenocarpic fruit set under optimal and non-permissive temperatures, in field and glasshouse conditions.

Chemical control of receptor kinase signaling by rapamycin-induced dimerization.

Mol Plant 2021 May 5. Epub 2021 May 5.

Department of Bioenergy Science and Technology, Chonnam National University, Gwangju, Korea; Kumho Life Science Laboratory, Chonnam National University, Gwangju, Korea; Department of Integrative Food, Bioscience and Biotechnology, Chonnam National University, Gwangju, Korea. Electronic address:

Membrane-localized leucine-rich repeat receptor kinases (LRR-RKs) sense diverse extracellular signals, and coordinate and specify cellular functions in plants. However, functional understanding and identification of the cellular signaling of most LRR-RKs remain a major challenge owing to their genetic redundancy, lack of ligand information, and subtle phenotypes of LRR-RK overexpression. Here, we report an engineered rapamycin-inducible dimerization (RiD) receptor system that triggers a receptor-specific LRR-RK signaling independent of their cognate ligands or endogenous receptors.
