Long-distance movement of RNA through the phloem is known to occur, but the functional importance of these transported RNAs has remained unclear. Grafting experiments with a naturally occurring dominant gain-of-function leaf mutation in tomato were used to demonstrate long-distance movement of mutant messenger RNA (mRNA) into wild-type scions. The stock-specific pattern of mRNA expression was graft transmissible, indicating that the mRNA accumulation pattern is inherent to the transcript and not

While the role of proteins in determining cell identity has been extensively studied, the contribution of small noncoding RNA molecules such as miRNAs and siRNAs has been also recognised. miRNAs bind to complementary sites in target mRNA molecules to trigger the degradation or translational inhibition of those targets. Recent studies have revealed that miRNAs play pivotal roles in key developmental processes such as patterning of the embryo, meristem, leaf, and flower. Furthermore, these miRNAs

Hybridization between species can lead to introgression of genes from one species to another, providing a potential mechanism for preserving and recombining key traits during evolution. To determine the molecular basis of such transfers, we analyzed a natural polymorphism for flower-head development in Senecio. We show that the polymorphism arose by introgression of a cluster of regulatory genes, the RAY locus, from the diploid species S. squalidus into the tetraploid S. vulgaris. The RAY genes

Purpose The concept of leader–member exchange (LMX) is well accepted in the service industry. This study examines how the quality of LMX helps hotels to achieve desirable outcomes, such as innovative behavior and job performance. The model was developed based on the LMX theory, and considers the relationship among the quality of LMX, employee engagement, innovative behavior and job performance. Design/methodology/approach The model was tested on employees of hotels in South Korea using a survey

This study used the value-attitude-behaviour model to test the hypothesized impacts of altruistic values and attitudes on environmentally responsible behaviour and destination loyalty. The study uses tourists’ environmental knowledge as a moderator in the proposed relationship. The participants were South Korean tourists visiting Jeju Island, a premier eco-destination that is experiencing a large influx of tourists. The results indicate the important role of altruistic values, attitudes, and env

Corporate social responsibility (CSR) has become a major part of the foodservice industry due to external forces which encourage enterprises’ responsiveness. In reality, consumers’ social concern influences their attitudes towards foodservice firms’ socially responsible practices and purchase decisions, thereby influencing senior management to react. Considering this issue, this study examines the impact of senior management’s ethical leadership in evaluating operational, commercial, and economi

Purpose This research examines the role of corporate social responsibility (CSR) in the workplace and its impact on frontline employees’ work-related outcomes. Based on the CSR and human resource management literature, this research formulates and tests a model of perceived management support for CSR, perceived customer support for CSR, work engagement, organization engagement, well-being and task performance, with an emphasis on the moderating role of the importance of CSR to employees. Design/

Travelers have increasingly used mega review sites as an information source during the decision-making processes. This study focuses on the significant role of the authenticity of online reviews on mega review sites in formulating travelers’ behavioral intention as well as trust toward both websites and their service (i.e., destinations). Extending trust transfer theory, this study aims to formulate a research model and investigate associations among three aspects of trust (i.e., cognitive and a

Gastric cancer is a malignancy that has a high mortality rate. Although progress has been made in the treatment of gastric cancer, many patients experience cancer recurrence and metastasis. Folate receptor 1 (FOLR1) is overexpressed on the cell surface in over one-third of gastric cancer patients, but rarely is expressed in normal tissue. This makes FOLR1 a potential target for chimeric antigen receptor (CAR) T cell immunotherapy, although the function of FOLR1 has not been elucidated. CAR are e

This study empirically investigates the dimensions of destination authenticity from the perspectives of outbound travelers from the United States. East Asian countries have invited Western tourists to their destinations by offering authentic, unique experiences of local life and culture. In response to this trend, this study examines the influences of destination authenticity on international tourists’ place attachment, destination satisfaction, and engagement on social media. Based on the liter
