Strigolactones (SLs), a group of carotenoid derived terpenoid lactones, are root-to-shoot phytohormones suppressing shoot branching by inhibiting the outgrowth axillary buds. DWARF 53 (D53), key repressor SL signaling pathway, is speculated to regulate downstream transcriptional network response. However, no transcription factor targeted D53 has yet been reported. Here we report that Ideal Plant Architecture 1 (IPA1), regulator plant architecture in rice, functions as direct component...
The rice root system is important for growth. crosstalk between auxin and cytokinin mediates initiation elongation. However, it remains unclear how the transcriptional network upstream of signalling pathways determines development. Here, we observed that knockdown OsNAC2, which encodes a NAC transcription factor, increased primary length number crown roots. OsNAC2 predominantly expressed in tips, roots lateral primordia, implying influences Molecular analyses revealed expressions auxin-...
Significance The aleurone, storing proteins, lipids, vitamins, and minerals, is the most nutritious part of cereal grains. Genetic analyses were conducted to screen for mutants with thickened identified thick aleurone 2-1 , which exhibits a multicell-layered an improved nutritional profile. Map-based cloning showed that TA2 encodes DNA demethylase. This study provides strategy enhancing value rice, possibly other cereals as well.
Abstract Abscisic acid (ABA) plays a multifaceted role in plant immunity and can either increase resistance or susceptibility to some bacterial fungal pathogens depending on the pathosystem. ABA is also known mediate defence viruses. In this study, relationship between pathway rice black‐streaked dwarf virus (RBSDV) was investigated rice. The expression of genes significantly reduced upon RBSDV infection. Application exogenous hormones various mutants revealed that negative against RBSDV....
Calcineurin B-like interacting protein kinases (CIPKs) play important roles via environmental stress. However, less is known how to sense the stress in molecular structure conformation level. Here, an OsCIPK7 mutant TILLING procedure with a point mutation kinase domain showed increased chilling tolerance, which could be potentially used breeding. We found that this of led conformational change activation loop domain, subsequently increase activity, thus conferred tolerance
Recent studies on regional haze pollution over China come up in general with strong variability of main causes heavy polluted episodes, linkage local specificities, sources and characteristics. This paper therefore aims at elucidating the specific formation mechanisms observed episodes 1–15 November 2015 Northeast region considered as one biggest megacity clusters China. The mega-city cluster, including Heilong Jiang, Jilin Liaoning provinces, is adjacent to Russia north, Mongolian west,...
Abstract. Wet scavenging is an efficient pathway for the removal of particulate matter (PM) from atmosphere. High levels PM have been a major cause air pollution in Beijing but decreased sharply under Air Pollution Prevention and Control Action Plan launched 2013. In this study, 4 years observations wet deposition conducted using sequential sampling technique to investigate detailed variation chemical components through each rainfall event. We find that ions, SO42-, Ca2+, NO3-, NH4+, show...
Barley is a diploid species with genome smaller than those of other members the Triticeae tribe, making it an attractive model for genetic studies in crops. The recent development barley genomics has created need high-throughput platform to identify genetically uniform mutants gene function investigations. In this study, we report ethyl methanesulfonate (EMS)-mutagenized population consisting 8525 M3 lines landrace "Hatiexi" (HTX), which complement high-quality de novo assembly reference...
Plant A/T-rich sequence- and zinc-binding protein (PLATZ) is a type of plant-specific zinc-dependent DNA-binding that binds to DNA sequences. This family essential for plant growth, development, stress response. In this study, 15 OsPLATZs were identified in the rice genome with complete PLATZ-conserved domains by CD-search, similar those found angiosperms. Multi-species phylogenetic analysis showed PLATZs conserved photosynthetic organisms, an evolutionary branch unique angiosperms was among...
Summary Most rice varieties are able to grow in red high‐Fe soil, but the underlying mechanism remains elusive. Through forward genetic screening, we identified a soil‐sensitive ‐ 1 ( rss1 ) mutant that exhibited severely retarded growth when grown soil showed no evident phenotype cinnamon soil. Under soil/high‐Fe conditions, increased Fe decreased copper (Cu) concentrations both roots and shoots, was partially rescued by Cu supplement. RSS1 encodes an OsSPL9 transcription factor is...
The stigma is the entry point for sexual reproduction in plants, but mechanisms underlying development are largely unknown. Here, we disrupted putative auxin biosynthetic and signaling genes to evaluate their roles rice (Oryza sativa) development. Disruption of PINOID (OsPID) gene completely eliminated stigmas, overexpression OsPID led overproliferation suggesting that a key determinant Interestingly, ospid mutants did not display defects flower initiation, nor they develop any pin-like...
Rice (Oryza sativa L.), a global staple food now grown on all inhabited continents, was domesticated from its wild progenitor, O. rufipogon Griff., in tropical and subtropical regions of Asia (Oka, 1988). After domestication, the expansions rice landraces into present-day range required diverse array adaptations to local environments, which included changes daylight sensitivity, expanded thermal tolerance (for excess cold heat), water availability (drought waterlogging), resistance biotic...
Abstract Rice (Oryza sativa) bacterial blight, caused by Xanthomonas oryzae pv. Oryzae (Xoo), threatens plant growth and yield. However, the molecular mechanisms underlying rice immunity against Xoo remain elusive. Here, we identified a NAC (NAM-ATAF-CUC) transcription factor OsNAC2 as negative regulator in resistance to blight disease rice. Constitutive overexpression of inhibited expression salicylic acid (SA) biosynthesis-related genes (i.e. isochorismate synthase 1 (OsICS1),...
Groove error is one of the most important factors affecting grating quality and spectral performance. To reduce groove error, we propose a new ruling-tool carriage system based on aerostatic guideways. We design blank with double piezoelectric actuators. also completely closed-loop servo-control optical measurement that can control position diamond relative to blank. evaluate our proposed methods, produced several gratings, including an echelle 79 grooves/mm, 768 high-density 6000...
Climate change negatively affects crop yield, which hinders efforts to reach agricultural sustainability and food security. Here, we show that a previously unidentified allele of the nitrate transporter gene OsNRT2.3 is required maintain high yield nitrogen use efficiency under temperatures. We demonstrate this tolerance temperatures in rice accessions harboring HTNE-2 (high temperature resistant efficient-2) alleles from enhanced translation OsNRT2.3b mRNA isoform decreased abundance unique...
Inflorescence architecture is important for rice (Oryza sativa) grain yield. The phytohormone cytokinin (CK) has been shown to regulate inflorescence development; however, the underlying mechanism mediated by CK perception still unclear. Employing a forward genetic approach, we isolated an inactive variant of receptor OHK4/OsHK4 gene named panicle length1, which shows decreased size due reduced meristem (IM) activity. A 2-amino acid deletion in long α-helix stalk sensory module OHK4 impairs...
The germination of seeds and establishment seedling are the preconditions plant growth antagonistically regulated by multiple phytohormones, e.g., ethylene, abscisic acid (ABA), gibberellic (GA). However, interactions between these phytohormones their upstream transcriptional regulation during seed in rice remain poorly understood. Here, we demonstrated a NAC (NAM-ATAF-CUC) transcription factor, OsNAC2, overexpression which increases ethylene sensitivity roots period. Further study proved...
Targeting-induced local lesions in genomes (TILLING) is a powerful reverse-genetics tool that enables high-throughput screening of genomic variations plants. Although TILLING has been developed for many diploid plants, the technology used very few polyploid species due to their complexity. Here, we established an efficient capillary electrophoresis-based platform allotetraploid cultivated tobacco (Nicotiana tabacum L.) using ethyl methanesulfonate (EMS)-mutagenized population 1,536...
