Abstract Soluble polyimide having an inherent viscosity up to 1.4 dL/g was synthesized by the high‐temperature solution polycondensation of 2,5‐bis(4‐isocyanatophenyl)‐3,4‐diphenylthiophene with 3,3′,4,4′‐benzophenonetetracarboxylic dianhydride. The tetraphenylthiophene diisocyanate trimellitic anhydride afforded polyamide‐imide 0.9 dL/g. These polymers showed limited solubility in organic solvents and had glass transition temperatures around 320°C.
Abstract The timing of germination is a key life‐history trait that may strongly influence plant fitness and sets the stage for selection on traits expressed later in life cycle. In seasonal environments, period favourable total length growing season are limited. optimal therefore be governed by conflicting through survival fecundity. We conducted field experiment to examine effects survival, fecundity overall natural population annual herb A rabidopsis thaliana north‐central Sweden....
Summary Polyploidization is pervasive in plants, but little known about the niche divergence of wild allopolyploids (species that harbor polyploid genomes originating from different diploid species) relative to their progenitor species and gene expression patterns may underlie such ecological divergence. We conducted a fine‐scale empirical study on habitat an allopolyploid its progenitors. quantified soil properties light availability habitats allotetraploid Cardamine flexuosa progenitors...
Background The effect of herbivory on plant fitness varies widely. Understanding the causes this variation is considerable interest because its implications for population dynamics and trait evolution. We experimentally defoliated annual herb Arabidopsis thaliana in a natural Sweden to test hypotheses that (a) decreases with increasing damage, (b) tolerance defoliation lower before flowering than during flowering, (c) reduces number seeds more strongly but opposite true effects seed size....
Abstract As sessile, photoautotrophic organisms, plants are subjected to fluctuating sunlight that includes potentially detrimental ultraviolet-B (UV-B) radiation. Experiments under controlled conditions have shown the UV-B photoreceptor UV RESISTANCE LOCUS 8 (UVR8) controls acclimation and tolerance in Arabidopsis thaliana; however, its long-term impact on plant fitness naturally environments remain poorly understood. Here, we quantified survival reproduction of different mutant genotypes...
Empirical evidence is limited on whether allopolyploid species combine or merge parental adaptations to broaden habitats. The
• Background and Aims Plants have the ability to compensate for damage caused by herbivores. This is important plant growth, because a cannot always avoid damage, even if it has developed defence mechanisms against In previous work, we elucidated herbivory-induced compensatory response of Quercus (at both individual shoot whole sapling levels) in low- high-nutrient conditions throughout one growing season. this study, determine how growth serrata saplings achieved at different nutrient levels.
The volume of information we handle is markedly increasing as a result the change from text data to still and moving image files. In this paper, propose describe fabrication much higher speed search engine for video using holographic optical disc system. Preliminary correlation experiments setup show an excellent performance indicated by high peaks low error rates at multiplexing pitch 10 µm, rotational 300 rpm. It clear that processing our calculation than conventional digital signal...
Abstract Although allopolyploid species are common among natural and crop species, it is not easy to distinguish duplicated genes, known as homeologs, during their genomic analysis. Yet, cost-efficient RNA sequencing (RNA-seq) be developed for large-scale transcriptomic studies such time-series analysis genome-wide association in allopolyploids. In this study, we employed a 3′ RNA-seq utilizing untranslated regions (UTRs) containing frequent mutations homeologous compared coding sequence....
Long-term field monitoring of leaf pigment content is informative for understanding plant responses to environments distinct from regulated chambers but impractical by conventional destructive measurements. We developed PlantServation, a method incorporating robust image-acquisition hardware and deep learning-based software that extracts color detecting individuals automatically. As case study, we applied PlantServation examine environmental genotypic effects on the anthocyanin estimated...
Abstract We investigated the combined effects of herbivore damage and soil fertility on shoot growth patterns Quercus serrata Q. crispula saplings at both individual levels. Saplings were grown in herbivore‐damaged or undamaged areas greenhouse with two fertilization treatment levels, low high. measured leaf area loss, number flushes, length extension units (EUs; first vs higher), leaves each individual, EUs. At level, loss high was significantly greater than that among highest EUs , while...
Herbivore damage can induce the host plant to alter chemical and physical qualities of its leaves, which is thought be a strategy—termed “induced response”—for avoiding further herbivory. In woody plants, many studies have considered variation in induced response with resource availability, but few examined this relation growth patterns plants. We studied phenotypic variability within successively flushing Quercus serrata seedlings. Q. seedlings were grown under controlled conditions. The...
Abstract Polyploidization, or whole genome duplication, is one of the major mechanisms plant speciation. Allopolyploids (species that harbor polyploid genomes originating from hybridization different diploid species) have been hypothesized to occupy a niche with intermediate, broader, fluctuating environmental conditions compared parental diploids. It remains unclear whether empirical data support this hypothesis and specialization expression patterns homeologs (paralogous gene copies...
Abstract As sessile organisms, plants are subjected to fluctuating sunlight including potentially detrimental ultraviolet-B radiation (UV-B). In Arabidopsis thaliana , experiments under controlled conditions have shown that UV RESISTANCE LOCUS 8 ( UVR8 ) controls photomorphogenic responses for acclimation and tolerance UV-B; however, its long-term impacts on plant performance remain poorly understood in naturally environments. Here we quantified the survival reproduction of different mutant...
Abstract Allopolyploids possess complete sets of genomes derived from different parental species and exhibit a range variation in various traits. Reproductive traits may play key role the reproductive isolation between allopolyploids their species, thus affecting thriving allopolyploids. However, empirical data, especially natural habitats, comparing trait remain rare. Here, we documented flowering phenology floral morphology allopolyploid wild plant Cardamine flexuosa its diploid parents C....
Abstract Long-term field monitoring of leaf pigment content is informative for understanding plant responses to environments distinct from regulated chambers, but impractical by conventional destructive measurements. We developed PlantServation, a method incorporating robust image-acquisition hardware and deep learning-based software analyze images, where the shape, color, background vary over months. estimated anthocyanin contents small individuals four Arabidopsis species using color...
