Well prepared It is well known that species radiate into new niches by adapting to novel environments. But why do some in this way, while other, related, not. Ishikawa et al. looked across sticklebacks determine some, originally marine, lineages were able colonize postglacial freshwater environments (see the Perspective Weber and Tong). They found a gene involved fatty acid desaturation was duplicated lineages. Transgenic manipulation of allowed marine synthesize acids thus survive on...
Acclimation to high temperature increases plants' tolerance of subsequent lethal temperatures. Although epigenetic regulation plant gene expression is well studied, how plants maintain a memory environmental changes over time remains unclear. Here, we show that JUMONJI (JMJ) proteins, demethylases involved in histone H3 lysine 27 trimethylation (H3K27me3), are necessary for Arabidopsis thaliana heat acclimation. induces sustained H3K27me3 demethylation at HEAT SHOCK PROTEIN22 (HSP22) and...
m-Diethynylbenzene macrocycles (DBMs), buta-1,3-diyne-bridged [4(n)]metacyclophanes, have been synthesized and their self-association behaviors in solution were investigated. Cyclic tetramers, hexamers, octamers of DBMs having exo-annular octyl, hexadecyl, 3,6,9-trioxadecyl ester groups prepared by intermolecular oxidative coupling dimer units or intramolecular cyclization the corresponding open-chain oligomers. The aggregation properties investigated two methods, (1)H NMR spectra vapor...
Abstract The circadian clock controls physiological traits such as flowering time, photosynthesis, and growth in plants under laboratory conditions. Under natural field conditions, however, little is known about the significance of plants. By time-course transcriptome analyses rice (Oryza sativa) leaves, using a newly isolated clock–related mutant carrying null mutation Os-GIGANTEA (Os-GI), we show here that Os-GI controlled 75% (false discovery rate = 0.05) genes among 27,201 tested was...
Abstract Ipomoea is the largest genus in family Convolvulaceae. nil (Japanese morning glory) has been utilized as a model plant to study genetic basis of floricultural traits, with over 1,500 mutant lines. In present study, we have second- and third-generation-sequencing platforms, reported draft genome I. scaffold N50 2.88 Mb (contig 1.87 Mb), covering 98% 750 genome. Scaffolds 91.42% assembly are anchored 15 pseudo-chromosomes. The enabled identification cataloguing Tpn1 transposons, known...
Abstract Microbes are easily dispersed from one place to another and immigrant microbes might contain information about the environments which they came. We hypothesized that part of microbial community on a flower's surface is transferred there insect body surfaces this can provide identify potential pollinator insects plant. collected samples field found an individual harbored average 12.2 × 10 5 cells its surface. A laboratory experiment showed composition flower changed after contact...
As research on plant viruses has focused mainly crop diseases, little is known about these in natural environments. To understand the ecology of systems, comprehensive information virus–virus and virus–host interactions required. We applied RNA-Seq to plants from a population Arabidopsis halleri subsp. gemmifera simultaneously determine presence/absence all sequence-reported viruses, identify novel quantify host transcriptome. By introducing criteria read number genome coverage, we detected...
RNA-Seq is a whole-transcriptome analysis method used to research biological mechanisms and functions but its use in large-scale experiments limited by high cost labour requirements. In this study, we have established high-throughput cost-effective library preparation that does not require mRNA enrichment. The adds unique index sequences samples during reverse transcription (RT) conducted at higher temperature (≥62 °C) suppress RT of A-rich rRNA, then pools all into single tube. Both...
PYK10/BGLU23 is a β-glucosidase that major protein of ER bodies, which are endoplasmic reticulum (ER)-derived organelles may be involved in defense systems. PYK10 has active and inactive forms. Active molecules form large complexes with diameters ranging from 0.65 μm to > 70 μm. We identified three β-glucosidases (PYK10, BGLU21 BGLU22), five jacalin-related lectins (JALs) GDSL lipase-like (GLL) the purified complex. Expression levels JALs GLLs were lower nai1-1 mutant, no than Col-0. The...
Abstract Quaternary climatic oscillations profoundly impacted temperate biodiversity. For many diverse yet undersampled areas, however, the consequences of this impact are still poorly known. In Europe, particular uncertainty surrounds role Balkans, a major hotspot European diversity, in postglacial recolonization more northerly and Carpathians, debatable candidate for northern ‘cryptic’ glacial refugium. Using genome‐wide SNP s microsatellites, we examined how interplay historical processes...
Adaptive divergence at the microgeographic scale has been generally disregarded because high gene flow is expected to disrupt local adaptation. Yet, growing number of studies reporting adaptive a small spatial highlight importance this process in evolutionary biology. To investigate genetic basis adaptation, we conducted genome-wide scan among sets continuously distributed populations Arabidopsis halleri subsp. gemmifera that show altitudinal phenotypic despite flow. Genomic comparisons were...
Persistent infection, wherein a pathogen is continually present in host individual, widespread virus-host systems. However, little known regarding how seasonal environments alter interaction during such metastability. We observed lineage-to-lineage infection of the plant Arabidopsis halleri with Turnip mosaic virus for 3 years without severe damage. Virus dynamics and interactions within hosts were highly season dependent. accumulation newly formed leaves was temperature dependent suppressed...
Summary Increase in the nitrogen (N)‐use efficiency and optimization of N response crop species are urgently needed. Although transcription factor‐based genetic engineering is a promising approach for achieving these goals, factors that play key roles to deficiency have not been studied extensively. Here, we performed RNA‐seq analysis root samples 20 Asian rice ( Oryza sativa ) accessions with differential nutrient uptake. Data obtained from plants exposed N‐replete N‐deficient conditions...
Leaves within crop canopies experience variable light over the course of a day, which greatly affects photosynthesis and productivity. Little is known about mechanisms photosynthetic response to fluctuating their genetic control. Here, we examined gas exchange, metabolite levels, chlorophyll fluorescence during induction in an Oryza sativa indica cultivar with high yield (Takanari) japonica lower (Koshihikari). Takanari had faster sudden increases intensity than Koshihikari, as demonstrated...
Under low iron (Fe) availability, plants transcriptionally induce various genes responsible for Fe uptake and translocation to obtain adequate amounts of Fe. Although transcription factors ubiquitin ligases involved in these deficiency responses have been identified, the mechanisms coordinating pathways not clarified rice. Recently identified Fe-deficiency-inducible IRON MAN (IMA)/FE UPTAKE-INDUCING PEPTIDE (FEP) positively regulates many Arabidopsis. Here, we report that expression two...
Abstract Sexual selection drives rapid phenotypic diversification of mating traits. However, we know little about the causative genes underlying divergence in sexually selected Here, investigate genetic basis male trait medaka fishes (genus Oryzias ) from Sulawesi, Indonesia. Using linkage mapping, transcriptome analysis, and genome editing, identify csf1 as a gene for red pectoral fins that are unique to woworae . A cis -regulatory mutation enables androgen-induced expression fins....
Chemical priming has emerged as a promising area in agricultural research. Our previous studies have demonstrated that pretreatment with low concentration of ethanol enhances abiotic stress tolerance Arabidopsis and cassava. Here, we show treatment induces heat tomato ( Solanum lycopersicon L.) plants. Seedlings the cultivar ‘Micro-Tom’ were pretreated solution then subjected to stress. The survival rates ethanol-pretreated plants significantly higher than those water-treated control...
Intriguing association behavior in solution is exhibited by the rigid macrocycle 1. For instance, it reacts with organic cations to give ternary complexes of composition (1⋅cation)⋅1, and analogous macrocycles without cyano groups forms heteroaggregates. R=CO2 C8 H17 .
