Abstract
The development of virus-free, oral vaccines against poliovirus capable of inducing mucosal protective immunity is needed to safely combat this pathogen. In the present study, a carrot cell line expressing the poliovirus VP2 antigen was established at the level of callus and cell suspensions, exploring the effects of culture media (MS and B5), supplementation with urea, phytoregulators (2,4-D : KIN), and light conditions (continuous light, photoperiod, and total darkness). The best callus growth was obtained on B5 medium supplemented with 2 mg/L of 2,4-D + 2 mg/L kinetin and 0.0136 g/L of urea and in continuous light conditions. Suspension cultures of the SMC-1 line in 250 mL Erlenmeyer flasks had a maximum growth of 16.07 ± 0.03 g/L DW on day 12 with a growth rate of µ=0.3/d and a doubling time of 2.3 days. In a 2 L airlift bioreactor, the biomass yield achieved was 25.6 ± 0.05 g/L DW at day 10 with a growth rate of µ= 0.58/d and doubling time of 1.38 d. Cell growth was 1.5 times higher in bioreactors than in shake flasks, highlighting that both systems resulted in the accumulation of VP2 throughout the time in culture. The maximum VP2 yield in flasks was 387.8 µg/g DW at day 21, while in the reactor it was 550.2 µg/g DW at day 18. In conclusion, bioreactor-based production of the VP2 protein by the SMC-1 suspension cell line offers a higher productivity when compared to flask cultures, offering a key perspective to produce low-cost vaccines against poliomyelitis.

Abstract
Porcine epidemic diarrhea virus (PEDV), a member of the Coronaviridae family has become increasingly probelmatic in the pig farming industry. Currently, there are no effective, globally applicable vaccines against PEDV. Here, we tested a recombinant PEDV vaccine candidate based on the expression of the core neutralising epitope (COE) of PEDV conjugated to polymeric immunoglobulin G scaffold (PIGS) in glycoengineered Nicotiana benthamiana plants. The biological activity of COE-PIGS was demonstrated by binding to C1q component of the complement system, as well as the surface of antigen-presenting cells (APCs) in vitro. The recombinant COE-PIGS induced humoral and cellular immune responses specific for PEDV after both systemic and mucosal vaccination. Altogether, the data indicated that PEDV antigen fusion to poly-Fc could be a promising vaccine platform against respiratory PEDV infection.

Abstract
Particle bombardment, or biolistics, has emerged as an excellent alternative approach for plant genetic transformation which circumvents the limitations of Agrobacterium-mediated genetic transformation. The method has no biological constraints and can transform a wide range of plant species. Besides, it has been the most efficient way to achieve organelle transformation (for both chloroplasts and mitochondria) so far. Along with the recent advances in genome editing technologies, conventional gene delivery tools are now being repurposed to deliver targeted gene editing reagents into the plants. One of the key advantages is that the particle bombardment allows DNA-free gene editing of the genome. It enables the direct delivery of proteins, RNAs, and RNPs into plants. Owing to the versatility and wide-range applicability of the particle bombardment, it will likely remain one of the major genetic transformation methods in the future. This article provides an overview of the current status of particle bombardment technology and its applications in the field of plant research and biotechnology.

Abstract
High expression of a transgene is often necessary to produce useful substances in plants. The efficiency of mRNA translation is an important determinant of the level of transgene expression. In dicotyledonous plants, the 5'UTR of certain mRNAs act as translational enhancers, dramatically improving transgene expression levels. On the other hand, translation enhancers derived from dicotyledonous plants are not so much effective in monocotyledonous plants, which are important as industrial crops and as hosts for production of useful substances. In this study, we evaluated the polysome association on a large scale with high resolution for each 5'UTR variant from multiple transcription start site in normal and heat-stressed Oryza sativa suspension cultures. Translational enhancer candidates were selected from the resultant large-scale data set, and their enhancer activities were evaluated by transient expression assay. In this manner, we obtained several translational enhancers with significantly higher activities than previously reported enhancers. Their activities were confirmed in a different monocotyledonous plant, Secale cereale, and using a different reporter gene. In addition, enhancer activities of tested 5'UTRs were different between monocotyledonous and dicotyledonous plants, suggesting that the enhancer activities were not compatible between them. Overall, we demonstrate these useful 5'UTRs as enhancer sequence for transgene expression in monocotyledonous plants.
