Abstract

Camellia oil extracted from the seeds of Camellia oleifera Abel. is a popular and high-quality edible oil, but its yield is limited by seed setting, which is mainly caused by self-incompatibility (SI). One of the obvious biological features of SI plants is the inhibition of self-pollen tubes; however, the underlying mechanism of this inhibition in C. oleifera is poorly understood. In this study, we constructed a semi-in vivo pollen tube growth test (SIV-PGT) system that can screen for substances that inhibit self-pollen tubes without interference from the genetic background. Combined with multi-omics analysis, the results revealed the important role of galloylated catechins in self-pollen tube inhibition, and a possible molecular regulatory network mediated by UDP-glycosyltransferase (UGT) and serine carboxypeptidase-like (SCPL) was proposed. In summary, galloylation of catechins and high levels of galloylated catechins are specifically involved in pollen tube inhibition under self-pollination rather than cross-pollination, which provides a new understanding of SI in C. oleifera. These results will contribute to sexual reproduction research on C. oleifera and provide theoretical support for improving Camellia oil yield in production. [ABSTRACT FROM AUTHOR]

Abstract

Camellia oleiferais an economically important woody oil plant. Complex ploidy and lack of genomic information have seriously hindered the molecular breeding of C. oleifera. Here, we present an 11.43-Gb haplotype-resolved, chromosome-level genome assembly of tetraploid C. oleifera(COL-tetra). Methods employed in this study support the conclusion that COL-tetrais an autotetraploid and probably originates from genome doubling of the diploid C. brevistyla. In addition, DNA methylation plays a significant role in imbalanced allelic expression and seed development. Genetic divergence analyses reveal significant differentiation signals for flowering time between spring-flowering and autumn-flowering oil Camelliaspecies, which probably account for reproductive isolation between species with distinct flowering times. Strong introgression signals are detected between COL-tetraand C. sasanquaand between C. vietnamensisand COL-hexa, which might affect the development of agronomic traits and environmental adaptability. This study provides valuable insights into the evolution, agronomic trait development, and genetic architecture of oil Camelliaplants.

17. The Impact of the Implementation of Stock Index Options on Stock Market Volatility: China Evidence

Author

Xiao, Shixin and Xiao, Shixin

Abstract

The stock market can be a leading indicator of a country's economic performance. In real life, the stock market is full of volatility and uncertainty. The emergence of stock index options enriches the financial market and expands the opportunities for investors. The effect of stock index options on stock market volatility has always been an interesting topic for financial researchers. This paper chooses to study the Chinese stock market and chooses the SSE 50 index as the main research object. By excluding the influence of domestic and international economic situation, this paper analyses the impact of the implementation of SSE 50 ETF option on the volatility of Chinese stock market and puts forward some suggestions according to the current situation. Based on the GARCH model and the TGARCH model, the consequences show that the implementation of SSE 50 ETF option reduces the volatility of the stock market, increases the impact of information on the stock market and improves the asymmetric effect of the stock market. Meanwhile, the judgments of investors on good and bad news are becoming more rational. However, after the implementation of the stock index option, the shock of the new news on the stock market volatility decreases and the shock of the old news increases, indicating that the efficiency of information transmission is reduced.

Abstract

Oranges are an important nutritional source for human health and have immense economic value. Here we present a comprehensive analysis of the draft genome of sweet orange (Citrus sinensis). The assembled sequence covers 87.3% of the estimated orange genome, which is relatively compact, as 20% is composed of repetitive elements. We predicted 29,445 protein-coding genes, half of which are in the heterozygous state. With additional sequencing of two more citrus species and comparative analyses of seven citrus genomes, we present evidence to suggest that sweet orange originated from a backcross hybrid between pummelo and mandarin. Focused analysis on genes involved in vitamin C metabolism showed that GalUR, encoding the rate-limiting enzyme of the galacturonate pathway, is significantly upregulated in orange fruit, and the recent expansion of this gene family may provide a genomic basis. This draft genome represents a valuable resource for understanding and improving many important citrus traits in the future.
