Multimetallic alloys (MMAs) with various compositions enrich the materials library increasing diversity and have received much attention in catalysis applications. However, precisely shaping MMAs mesoporous nanostructures mapping distributions of multiple elements remain big challenge due to different reduction kinetics metal precursors complexity crystal growth. Here we design a one-pot wet-chemical approach synthesize core-shell motif PtPdRhRuCu nanospheres (PtPdRhRuCu MMNs) using diblock...
Abstract Sex chromosomes are particularly interesting regions of the genome for both molecular genetics and evolutionary studies; yet, most species, we lack basic information, such as gene order along chromosome. Because they recombination, Y-linked genes cannot be mapped genetically, leaving physical mapping only option establishing extent synteny homology with X Here, developed a novel general method deletion non-recombining by solving “the travelling salesman problem” evaluate its...
SUMMARY Laminarialean plants undergo heteromorphic alternation of generations between the macroscopic diploid sporophyte and microscopic haploid gametophyte. The change through formation release asexual or sexual reproductive cells. It is difficult to monitor diffusion zoospores into environment. Furthermore, even if can be detected, species identification remains difficult. This study attempted develop a sensitive fast method for laminarialean using quantitative PCR. In addition, we aimed...
The evolution of dioecy from hermaphroditism allows for avoidance self-pollination, and its evolutionary background has been investigated both experimentally theoretically since it was first proposed by Darwin. To reproduce this evolution, we screened hermaphroditic mutants Silene latifolia using heavy-ion beam or γ-ray irradiation characterized the phenotypes their floral organs. Our scatterplots indicate severe deviations trade-off relationships between pollen ovule numbers seed germinated...
When Microbotryum lychnidis-dioicae infects a male Silene latifolia, M. smut spores develop in the pollen sac instead of pollen. In contrast, when female S. flowers become male-like, promoting stamen formation. However, it is unclear and how invades anther. It important to investigate not only whether hyphae exist apical meristem tissue differentiates into anthers, but also filaments form. We used Grocott's methenamine silver stain lectin stain, which chitin fungal cell wall, search for...
Silene latifolia is a dioecious flowering plant with sex chromosomes in the family Caryophyllaceae. Development of gynoecium and stamens are suppressed male female flowers S. latifolia, respectively. Microbotryum lychnidis-dioicae promotes stamen development when it infects flower. If suppression regulated by same mechanism, released simultaneously infection M. lychnidis-dioicae. To assess this hypothesis, an asexual mutant without or was infected A filament elongated at stages 11 12 flower...
Mechanisms of suppression pistil primordia in male flowers and stamen female differ diclinous plants. In this study, we investigated how cell death cycle arrest are related to flower organ formation Silene latifolia. Using situ hybridization a TUNEL (terminal deoxynucleotidyl transferase dUTP nick end labeling) assay, detected both suppressed stamens pistils S. infected with Microbotryum lychnidis-dioicae, developmental is released, do not occur. Smut spores formed latifolia anthers M....
Scanning electron microscopy (SEM) is used to observe surface structures. The beam generally scans the cell at an acceleration voltage of 10–15 kV. We observed buried gold particles in cells 30 In this paper, dim, opaque were on a leaf that was bombarded with using particle gun. These epidermal and outline not clear compared adhered surface. A 1-µm hole (0.785 µm2 area) made by around particle. measured areas holes passage 1 min (n=61), 2 (n=56), 5 (n=110), 10 (n=61) after bombardment images...
Abstract Silene latifolia is a dioecious flowering plant with sex chromosomes in the family Caryophyllaceae. Development of gynoecium and stamens are suppressed male female flowers S. , respectively. Microbtryum lychnidis-dioicae promotes stamen development when it infects flower. If suppression regulated by same mechanism, released simultaneously infection M. . To assess this hypothesis, an asexual mutant, without or stamen, was infected A filament mutant elongated at stages 11 12 flower...
