Abstract Hydrogen sulfide (H 2 S) is a newly‐discovered signaling molecule in plants and has caused increasing attention recent years, but its function stomatal movement unclear. In plants, H S synthesized via cysteine degradation catalyzed by D‐/L‐cysteine desulfhydrase (D‐/L‐CDes). AtD‐/L‐CDes::GUS transgenic Arabidopsis thaliana (L.) Heynh. were generated used to investigate gene expression patterns, results showed that AtD‐/L‐CDes can be expressed guard cells. We also determined the...

Plastic pollution is fast becoming one of the most pressing global issues that we currently face. Remote areas, such as polar regions and Tibetan Plateau, are now also exposed to microplastic contamination. However, with impact warming, transport microplastics within glacier-lake basins in remains unclear. In this work, Nam Co Basin Plateau was selected study characteristics rain fallout, lake water, glacial runoff, non-glacial runoff. Fiber films were common morphologies all water samples;...

Abstract Spatial analysis of microbiomes at single cell resolution with high multiplexity and accuracy has remained challenging. Here we present spatial profiling a microbiome using sequential error-robust fluorescence in situ hybridization (SEER-FISH), highly multiplexed accurate imaging method that allows mapping microbial communities micron-scale. We show RNA can be increased significantly by rounds probe dissociation. Combined error-correction strategies, demonstrate SEER-FISH enables...

Fungal pathogens are a major constraint to global crop production; hence, plant genes encoding pathogen resistance important tools for combating disease. A few identified date provide partial, durable multiple and the wheat (Triticum aestivum) Lr67 hexose transporter variant (Lr67res) fits into this category. Two amino acids differ between wild-type resistant alleles - G144R V387L. Exome sequence data from 267 barley (Hordeum vulgare) landraces wild accessions was screened neither of Lr67res...

Abstract Flavonoids are essential for male fertility in some but not all plant species. In rice (Oryza sativa), the chalcone synthase mutant oschs1 produces flavonoid-depleted pollen and is sterile. The grains viable with normal structure, they display reduced germination rate pollen-tube length. Analysis of oschs1/+ heterozygous lines shows that flavonoid deposition a paternal effect independent haploid genotypes (OsCHS1 or oschs1). To understand which classes flavonoids involved fertility,...

Abstract Lignin is a complex phenylpropanoid polymer deposited in the secondary cell walls of vascular plants. Unlike most gymnosperm and eudicot lignins that are generated via polymerization monolignols, grass additionally incorporate flavonoid tricin as natural lignin monomer. The biosynthesis functions tricin-integrated (tricin-lignin) its effects on utility biomass remain largely unknown. We herein report comparative analysis rice (Oryza sativa) mutants deficient early biosynthetic genes...

Flavonoids are ubiquitous in terrestrial plants with important physiological functions. The planta flavonoid profile depends on the activities of different biosynthesis enzymes (Figure 1a). Flavanone 3-hydroxylase (F3H) is a key enzyme channelling carbon flow towards production 3-hydroxylated flavonoids, including flavonols and anthocyanidins. In Poaceae, F3H-encoding genes generally inactive vegetative tissues which accumulate flavone derivatives as predominant metabolites. Meanwhile,...

Evidence of the relationship between platelet count and 30-day in-hospital mortality in ICU stroke patients is still scarce. Therefore, purpose this study was to explore among patients.

In rice (Oryza sativa), OsF2H and OsFNSII direct flavanones to independent pathways that form soluble flavone C-glycosides tricin-type metabolites (both lignin-bound), respectively. Production of tricin requires CYP75B4 as a chrysoeriol 5'-hydroxylase. Meanwhile, the close homologue CYP75B3 is canonical flavonoid 3'-hydroxylase (F3'H). However, their precise roles in biosynthesis tricin-lignins cell walls remain unknown. We examined expression vegetative tissues, analyzed extractable...

Summary Tricin (3′,5′‐dimethoxylated flavone) is a predominant flavonoid amongst monocots but occurs only in isolated and unrelated dicot lineages. Although tricin biosynthesis has been intensively studied monocots, it remained largely elusive tricin‐accumulating dicots. We investigated subgroup of cytochrome P450 (CYP) 75B subfamily B‐ring hydroxylases (FBHs) from two legumes, Medicago truncatula alfalfa ( sativa ), by phylogenetic, molecular, biochemical mutant analyses. Five CYP75B FBHs...
