Regulatory landscape and public perception for gene-edited bananas in the Southeast Asian region.

Banana is a premier fruit crop in many parts of the world especially Southeast Asia. The demand for banana has contributed to significant national income to primary banana producers in the SEA region such as the Philippines, Indonesia, Thailand, Vietnam, and Malaysia. However, the widely traded banana industry is plagued by numerous threats including pests and diseases, post-harvest issues and extreme climate vulnerability. To address these challenges, new breeding techniques such as gene editing have been explored for breeding programs to develop improved banana varieties. The first gene-edited non-browning banana has been deregulated in the Philippines recently, and more regulatory applications are expected to submit for approvals soon. Hence, it is timely to review the policy options for gene editing that have been adopted and discussed in the Southeast Asian countries and highlight the implications of differing regulatory approaches to gene editing for trading activities. Positive stakeholders' perceptions and public acceptance are key factors in allowing the benefits of gene editing and thus appropriate outreach strategies are important to gain acceptance and avoid the "GMO stigma" that may be associated with gene-edited products.

Biotechnology policies and regulations must be revised and updated to reflect the most recent advances in plant-breeding technology. New Plant Breeding Techniques (NPBT) such as gene editing have been applied to address the myriad of challenges in plant breeding, while the use of NPBT as emerging biotechnological tools raises legal and ethical concerns. This study aims to highlight how gene editing is operationalized in the existing literature and examine the critical issues of ethical and legal issues of gene editing for plant breeding. We carried out a systematic literature review (SLR) to provide the current states of ethical and legal discourses surrounding this topic. We also identified critical research priority areas and policy gaps that must be addressed when designing the future governance of gene editing in plant breeding.

Digitization of natural history collections: A guideline and nationwide capacity building workshop in Malaysia.

Natural history museum collections are the most important sources of information on the present and past biodiversity of our planet. Most of the information is primarily stored in analogue form, and digitization of the collections can provide further open access to the images and specimen data to address the many global challenges. However, many museums do not digitize their collections because of constraints on budgets, human resources, and technologies. To encourage the digitization process, we present a guideline that offers low-cost and technical knowledge solutions yet balances the quality of the work and outcomes. The guideline describes three phases of digitization, namely preproduction, production, and postproduction. The preproduction phase includes human resource planning and selecting the highest priority collections for digitization. In the preproduction phase, a worksheet is provided for the digitizer to document the metadata, as well as a list of equipment needed to set up a digitizer station to image the specimens and associated labels. In the production phase, we place special emphasis on the light and color calibrations, as well as the guidelines for ISO/shutter speed/aperture to ensure a satisfactory quality of the digitized output. Once the specimen and labels have been imaged in the production phase, we demonstrate an end-to-end pipeline that uses optical character recognition (OCR) to transfer the physical text on the labels into a digital form and document it in a worksheet cell. A nationwide capacity workshop is then conducted to impart the guideline, and pre- and postcourse surveys were conducted to assess the confidence and skills acquired by the participants. This paper also discusses the challenges and future work that need to be taken forward for proper digital biodiversity data management.

Recent Progress on Nanocarriers for Topical-Mediated RNAi Strategies for Crop Protection-A Review.

To fulfil the growing needs of the global population, sustainability in food production must be ensured. Insect pests and pathogens are primarily responsible for one-third of food losses and harmful synthetic pesticides have been applied to protect crops from these pests and other pathogens such as viruses and fungi. An alternative pathogen control mechanism that is more "friendly" to the environment can be developed by externally applying double-stranded RNAs (dsRNAs) to suppress gene expression. However, the use of dsRNA sprays in open fields is complicated with respect to variable efficiencies in the dsRNA delivery, and the stability of the dsRNA on and in the plants, and because the mechanisms of gene silencing may differ between plants and between different pathogen targets. Thus, nanocarrier delivery systems have been especially used with the goal of improving the efficacy of dsRNAs. Here, we highlight recent developments in nanoparticle-mediated nanocarriers to deliver dsRNA, including layered double hydroxide, carbon dots, carbon nanotubes, gold nanoparticles, chitosan nanoparticles, silica nanoparticles, liposomes, and cell-penetrating peptides, by review of the literature and patent landscape. The effects of nanoparticle size and surface modification on the dsRNA uptake efficiency in plants are also discussed. Finally, we emphasize the overall limitation of dsRNA sprays, the risks associated, and the potential safety concerns for spraying dsRNAs on crops.

Genetic modification in Malaysia and India: current regulatory framework and the special case of non-transformative RNAi in agriculture.

Recent developments in modern biotechnology such as the use of RNA interference (RNAi) have broadened the scope of crop genetic modification. RNAi strategies have led to significant achievements in crop protection against biotic and abiotic stresses, modification of plant traits, and yield improvement. As RNAi-derived varieties of crops become more useful in the field, it is important to examine the capacity of current regulatory systems to deal with such varieties, and to determine if changes are needed to improve the existing frameworks. We review the biosafety frameworks from the perspective of developing countries that are increasingly involved in modern biotechnology research, including RNAi applications, and make some recommendations. Malaysia and India have approved laws regulating living modified organisms and products thereof, highlighting that the use of any genetically modified step requires regulatory scrutiny. In view of production methods for exogenously applied double-stranded RNAs and potential risks from the resulting double-stranded RNA-based products, we argue that a process-based system may be inappropriate for the non-transformative RNAi technology. We here propose that the current legislation needs rewording to take account of the non-transgenic RNAi technology, and discuss the best alternative for regulatory systems in India and Malaysia in comparison with the existing frameworks in other countries.

Global trends in research and commercialization of exogenous and endogenous RNAi technologies for crops.

It has only been about 20 years since the first Nobel Prize-winning work on RNA interference (RNAi) in Caenorhabditis elegans was published in the journal Nature. Fast forward to today, and the use of RNA molecules as gene-silencing elements in crops has helped scientists to unveil possible solutions to the global problems of agricultural losses due to pests, viruses, pathogens, and to other abiotic and biotic stresses. The recent proliferation of publications suggests that the technology has gained significant attention and received ample funding support. In this article, an attempt has been made to visualize recent trends in Research & Development (R&D) investment in this field by analyzing top cited scholarly articles, patent trends, and commercialization activity. The publication and citation analysis identified that the development of RNAi-based crops conferring resistance against viruses, fungi, and pests are at the forefront of RNAi research and that Chinese and US institutions are the leaders in this field. The patent landscape analysis for RNAi technology over all aspects related to RNAi-derived crops provides an overview of patenting activity from a geographical, organizational, and legal perspective. Such an exercise is pivotal to industry players and public institutions aiming at creating intellectual property that is commercially appealing. An upswing in commercial interests in this technology in recent years is reflected by a consistent number of patent filings in US, European, and Chinese patent offices, with multinational giant firms as the most prolific patent filers. The expanding RNAi commercialization landscape is supported by a series of strategic partnerships, licensing agreements, and acquisitions created between agribusinesses, public research institutions, and startup companies. From key observations, we would like to highlight that such investments have very positive impacts on the development of RNAi technology. Nonetheless, the success of this technology is dependent on several factors, such as financial requirements, the complexity, and timeframe of the entire development process, as well as stringent regulations imposed by the relevant authorities. In most countries, RNAi-based transgenic crops are still considered as a genetically modified (GM) product, which necessitates the crops to undergo rigorous evaluation before approval is granted. Recent advancements in exogenous RNAi-derived biopesticides have provided a nontransgenic alternative to GM crops. However, challenges still remain in the form of technical hurdles and regulatory ambiguities surrounding this emerging technology. Its full potential remains to be realized.
