Abstract: In photosynthesis Ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco) catalyses the often rate limiting CO 2 -fixation step in the Calvin cycle. This makes Rubisco both the gatekeeper for carbon entry into the biosphere and a target for functional improvement to enhance photosynthesis and plant growth. Encumbering the catalytic performance of Rubisco is its highly conserved, complex catalytic chemistry. Accordingly, traditional efforts to enhance Rubisco catalysis using protracted “trial and error” protein engineering approaches have met with limited success. Here we demonstrate the versatility of high throughput directed (laboratory) protein evolution for improving the carboxylation properties of a non-photosynthetic Rubisco from the archaea Methanococcoides burtonii . Using chloroplast transformation in the model plant Nicotiana tabacum (tobacco) we confirm the improved forms of M. burtonii Rubisco increased photosynthesis and growth relative to tobacco controls producing wild-type M. burtonii Rubisco. Our findings indicate continued directed evolution of archaeal Rubisco offers new potential for enhancing leaf photosynthesis and plant growth.

Abstract: The purpose of this paper is to examine the impact of social commerce (s-commerce) cues (i.e. trust, compatibility, reliability and responsiveness) on repurchase intention in apparel s-commerce along with the mediating effect of customer engagement and the moderating effect of s-commerce navigation. Using the purposive s ling technique, face-to-face survey was administered to Gen-Y social media users in Malaysia. Subsequently, 384 respondents were s led. Partial least squares-structural equation modeling was used to perform the analyses. S-commerce cues have a positive effect on customer engagement, which in turn leads to repurchase intention of apparel among Gen-Y. Particularly, customer engagement also mediates the relationship between s-commerce cues and repurchase intention. S-commerce navigation is found to moderate the effect of engagement on repurchase intention. The findings are derived from the perception of Gen-Y in Malaysia and do not represent the entire population. Future research could investigate the same phenomena across generations and consider heterogeneity issues to provide more insights. Apparel s-commerce retailers are suggested to engage with customers more in the e-retail environment to build a lasting relationship. Contextual factors such as ease of navigation should be observed to enhance the desired response of erse customers today. This study adds to the growing body of knowledge on relationship marketing by assessing the impact of customer engagement and navigation on the relationships between s-commerce cues and repurchase intention in the contemporary setting.

Abstract: Underpinned by Script Theory and the S-O-R model, this research enhances the green tourism consumption literature to identify how destination service quality contributes to visitors’ memorable experiences and loyalty towards a place-based food tourism attraction. A total of 202 tourists who visited the Best of Highlands tea plantation in Malaysia were surveyed using an online questionnaire. Using PLS-SEM, this study has several notable findings: (i) destination service quality factors: activities, cleanliness, language, and security emerged as predictors of memorable tourism experiences (ii) memorable tourism experiences strongly predicted destination loyalty and (iii) memorable tourism experiences mediate the path between destination service quality and destination loyalty. This study therefore provides new insights into both sustainable tea tourism and script theory with respect to how memories guide future decision making. These results also provide insights for tea tourism providers in designing an unforgettable destination that stimulates the tourist’s intention to revisit the destination and to communicate it to others.

Abstract: China has become the number one source market for tourists. This article seeks to understand whether cultural/lifestyle similarity is an important pull factor for Chinese tourists when selecting a destination. Specifically, 205 Chinese tourists were surveyed about their destination choices in relation to the seven most visited outbound destinations. The results from a latent class regression analysis found a similarity-driven segment to exist for all seven destinations, with segment sizes ranging from 22% to 62% of the s le. These results suggest that a substantial segment of Chinese tourists are motivated by perceived cultural/lifestyle similarity. Generally, those with high ethnocentrism, high uncertainty avoidance, low novelty seeking or less travel experience are more likely to belong to the similarity-driven segment. Further research is needed to examine the size of this segment in larger, more inclusive cities of the Chinese population, as the current study only concentrated on tourists from three major cities.
