Pi acquisition of crops via arbuscular mycorrhizal (AM) symbiosis is becoming increasingly important due to limited high-grade rock reserves and a demand for environmentally sustainable agriculture. Here, we show that 70% the overall acquired by rice (Oryza sativa) delivered symbiotic route. To better understand this pathway, combined genetic, molecular, physiological approaches determine specific functions two symbiosis-specific members PHOSPHATE TRANSPORTER1 (PHT1) gene family from rice,...
ZIP transporters (ZRT, IRT-like proteins) are involved in the transport of iron (Fe), zinc (Zn) and other divalent metal cations. The expression IRT3, a transporter, is higher Zn/cadmium (Cd) hyperaccumulator Arabidopsis halleri than that its ortholog thaliana, which implies positive association with Zn accumulation A. halleri. IRT3 genes from both thaliana functionally complemented uptake mutant Spzrt1 Schizosaccharomyces pombe; double zrt1zrt2, Fe-uptake fet3fet4 conferred Fe activity...
Abstract Plant vacuoles serve as the primary intracellular compartments for inorganic phosphate (Pi) storage. Passage of Pi across vacuolar membranes plays a critical role in buffering cytoplasmic level against fluctuations external and metabolic activities. Here we demonstrate that SPX-MFS proteins, designated PHOSPHATE TRANSPORTER 5 family (PHT5), also named Vacuolar Phosphate Transporter (VPT), function transporters. Based on 31 P-magnetic resonance spectroscopy analysis, Arabidopsis...
Early stages of a beneficial relationship Plants benefit from widespread symbiosis with arbuscular mycorrhizal fungi. This between plant and fungus aids plants in capturing mineral micronutrients the soil. Gutjahr et al. have now identified component an intracellular receptor, hydrolase DWARF 14 LIKE, required rice roots for initiating symbiosis. A similar receptor detects karrikins smoke that signal opportunity fireweed to grow after forest fire. Science , this issue p. 1521
As an essential nutrient element, phosphorus (P) is primarily acquired and translocated as inorganic phosphate (Pi) by plant roots. Pi often sequestered in the soil becomes limited for growth. Plants have developed a sophisticated array of adaptive responses, termed P starvation to cope with deficiency improving its external acquisition internal utilization. Over past 2 3 decades, remarkable progress has been made toward understanding how plants sense respond changing environmental P. This...
Abstract The involvement of nuclear factor Y (NF-Y) in transcriptional reprogramming during arbuscular mycorrhizal symbiosis has been demonstrated several plant species. However, a comprehensive picture is lacking. We showed that the spatial expression NF-YC3 was observed cortical cells containing arbuscules via cis-regulatory element GCC boxes. Moreover, promoter transactivated by combination CYCLOPS and autoactive calcium calmodulin-dependent kinase (CCaMK) Knockdown significantly reduced...
Rice (Oryza sativa) OsNLA1 has been proposed to play a crucial role in regulating phosphate (Pi) acquisition roots, similar that of Arabidopsis (Arabidopsis thaliana) AtNLA. However, unlike AtNLA, is not target miR827, Pi starvation-induced microRNA. It is, therefore, interest know whether the expression depends on supply and how it regulated. In this study, we provide evidence controls by directing degradation several OsPHT1 transporters (i.e. OsPT1/2/4/7/8/12). We further show an...
Plant lateral root (LR) growth usually is stimulated by arbuscular mycorrhizal (AM) symbiosis. However, the molecular mechanism still unclear. We used gene expression analysis, peptide treatment and virus-induced alteration assays to demonstrate that C-terminally encoded (CEP2) in tomato was downregulated during AM symbiosis mitigate its negative effect on LR formation through an auxin-related pathway. showed enhanced density CEP2 were observed Synthetic reduced impaired of genes involved...
In the past few decades, non-coding RNAs (ncRNAs) have emerged as important regulators of gene expression in eukaryotes. Most studies ncRNAs plants focused on identification silencing microRNAs (miRNAs) and small interfering (siRNAs). Another family that has been well characterized is nucleolar (snoRNAs) related Cajal body-specific (scaRNAs). Both target chemical modifications ribosomal (rRNAs) nuclear (snRNAs). plants, snoRNA genes are organized clusters, transcribed by RNA Pol II from a...
More than half of the global population relies on rice as a staple food, but salinization soil presents great threat to cultivation. Although previous studies have addressed possible benefits arbuscular mycorrhizal (AM) symbiosis for under salinity stress, underlying molecular mechanisms are still unclear. In this study, we found that had better shoot and reproductive growth significantly higher K+/Na+ ratio in shoot. The reactive oxygen species (ROS) scavenging capacity shoots was also...
