In this report, self-sterility in Camellia oleifera was explored by comparing structural and statistical characteristics following self-pollination (SP) cross-pollination (CP). Although slightly delayed pollen germination tube growth selfed ovaries compared to crossed observed, there no significant difference the percentages of that germinated tubes grew base style. There also morphological structure after two pollination treatments. However, proportions ovule penetration double...

Interestingly, some protein domains are intrinsically disordered (abbreviated as IDD), and the disorder degree of same may differ in different contexts. However, evolutionary causes biological significance these phenomena unclear. Here, we address issues by genome-wide analyses functional features IDDs 1,870 species across three superkingdoms. As result, there is a significant positive correlation between proportion organism complexity with interesting exceptions. These be due to high...

Relay cropping of Poaceae and Fabaceae promotes high yield land-use efficiency by allowing a double harvest. However, it is difficult to increase synergistically because the reduced photosynthetic abilities legume leaves under shade graminoids. Leaf capacity in relay systems associated with ecological niche differentiation compensation after restoration normal light. We conducted field experiment southwest China 2020–2021 evaluate effects three patterns: maize–soybean (IMS), monoculture...

Camellia oleifera is an important plant species that produces edible oils. Understanding the double fertilization of this critical for studies concerning crossbreeding, self-incompatibility, and biological mechanisms underlying hybridization. We aimed to characterize pollen tube growth in C. . The female male parent cultivars (Huashuo Xianglin XLC15, respectively) were used artificial pollination. Growth style, ovary, ovule from pollination cytological characteristics gamete fusion during...

Abstract To assess the adaptability of Camellia oleifera for introduction in new growth locations, this study evaluated 10 representative C. cultivars from main areas China where oil-producing evergreen crop is grown. Cluster analysis, correlation and membership function analysis were used to evaluate various indices selected cultivars, including flowering phenology, cold tolerance, leaf structure, pollen characteristics, viability. The identified full blossoming time, palisade spongy tissue...

Abstract Using the blueberry cultivar "Powderblue" after pollination, fruits at different developmental stages were collected for study. The transverse and longitudinal diameters, individual fruit weight, water content measured during their development. Employing tissue sectioning microscopy techniques, we systematically studied morphological features anatomical structures of seeds various stages, aiming to elucidate cytological patterns results our study revealed that growth development...

Abstract Although Chaenomeles is widely used in horticulture, traditional Chinese medicine and landscape greening, insufficient research has hindered its breeding seed selection. This study investigated the floral phenology, organ characteristics, palynology, systems of speciosa (Sweet) Nakai. The characteristics C. were observed both visually stereoscopically. microstructures flower organs using scanning electron microscopy. Pollen stainability was determined triphenyl tetrazolium chloride...

This paper presents several control methods and realizes the stable tracking for inverted pendulum system. Based on advantages of RBF traditional PID, a novel PID controller based neural network supervision method (PID-RBF) is proposed. adaptive adjustment signal Furthermore, an improved strategy (IPID-RBF) presented. adopts feed-forward feedback. The response speed system further improved, overshoot reduced. simulation under three different signals given to illustrate effectiveness proposed method.

Abstract In this study, we assessed 26 economic characteristics and yields of the mature fruit 40 superior Camellia oleifera Abel plants grown at C. germplasm resource nursery in low-hot valley area Southwest Zuizhou, China, using principal component analysis (PCA). Correlations among variability these were also analyzed. Out characteristics, 16 primary selected for comprehensive assessment, based on results which ordered to obtain excellent germplasms. The data subjected PCA, integrated...

Abstract Alzheimer’s disease (AD) is a progressive neurodegenerative disorder characterized by massive neuronal loss in the brain. Both cortical glutamatergic neurons and basal forebrain cholinergic (BFCNs) AD brain are selectively vulnerable. The degeneration dysfunction of these two subtypes closely associated with cognitive decline patients. determination cellular molecular mechanisms involved pathogenesis, especially early stage, will largely facilitate understanding this development...

The consecutive disordered regions (CDRs) are the basis for formation of intrinsically proteins, which contribute to various biological functions and increasing organism complexity. Previous studies have revealed that CDRs may be present inside or outside protein domains, but a comprehensive analysis property differences between these two types proteins containing them is lacking. In this study, we investigated issue from three viewpoints. Firstly, found in-domain more hydrophilic stable...

Abstract Wangmo red ball Camellia oleifera is the main species cultivated for oil in low-heat valley of Guizhou, China. In this study, we evaluated comprehensive nutritional value C. seed through fatty acid and component analyses. Twenty excellent plants with stable yield disease resistance were selected from germplasm resource garden site Guizhou University. The unit crown yield, content oil, composition functional nutrients determined, quality was comprehensively using principal analysis....

Camellia oleifera , a major woody oil plant, has low yield because of self-incompatibility. For commercial production, compatible pollen and optimal cross-pollination combinations are required. To evaluate the effects pollination compatibility source on quality, four C. cultivars—Huashuo (HS), Huajin (HJ), Huaxin (HX), Xianglin XLC15 (XL)—were subjected to self-, cross-, natural pollination. Pollen compatibility, yield, quality indices were analyzed. There no significant differences in...

How genome complexity affects organismal phenotypic is a fundamental question in evolutionary developmental biology. Previous studies proposed various contributing factors of and tried to find the connection between genomic organism complexity. However, general model answer this lacking. Here, we introduce 'two-level' for realization at level. Five representative species across Protostomia Deuterostomia were involved study. The intrinsic gene properties classified into two generalized...

the reproductive cells are enlarged as begin to move away from pollen wall.Two-cell is first formed after have left wall, and number of inclusions in subsequently increases.The matures for 5-8 days before flowering occurs.No abortion phenomena were observed, suggesting that anther development C. oleifera normal functional formed.

The mechanism by which calcium regulates anther development remains unclear. This study investigated the relationship between distribution and in oil tea ( Camellia oleifera Abel.) using potassium antimonite technique. Before onset of microsporogenesis, abundant minute precipitates appeared on plasma membranes microspore mother cells. Meanwhile, numerous accumulated tapetal After meiosis, young microspores. During development, mainly small vacuoles cytoplasm. At late stage, a large vacuole...
