Abstract
Grapevine is an important fruit crop cultivated worldwide. Previously, we have reported the characterization of a salt stress-inducible gene Vv-α-gal/SIP isolated from the tolerant grapevine cultivar Razegui. In this study, we performed functional studies in both Escherichia coli and tobacco systems to gain more insights in the role of the Vv-α-gal/SIP gene. Our data revealed that the recombinant E. coli cells harboring the pET24b+ expression vector with the Vv-α-gal/SIP showed higher tolerance to desiccation and salinity compared to E. coli cells harboring the vector alone. In addition, the transgenic tobacco plants expressing the Vv-α-gal/SIP gene exhibited a higher percentage of seed germination and better growth under salt stress than the wild-type (WT) tobacco seedlings. This stress mitigation might be related to the putative function of this gene, which is thought to be involved in carbohydrate metabolism regulation. Collectively, these results suggest that Vv-α-gal/SIP is potentially a candidate gene for engineering drought and salt tolerance in cultivated plants.

Abstract
The aim of this study was to investigate how the combination of extraction parameters, such as extraction temperature seeds preheating and screw rotation speed, influenced the yield and chemical quality of tobacco seed oil (TSO). For its peculiar properties, TSO can be used for several purposes, as raw material in the manufacturing of soap, paints, resins, lubricants, biofuels and also as edible oil. TSO was obtained using a mechanical screw press and the quality of the oil was evaluated by monitoring the free fatty acids (FFA), the peroxide value (PV), the spectroscopic indices K232, K270 and ΔK and the fatty acid composition. The maximum extraction yield, expressed as percent of oil mechanically extracted respect to the oil content in the seeds, determined by solvent extraction, was obtained with the combination of the highest extraction temperature, the slowest screw rotation speed and seeds preheating. Under these conditions yield was 80.28 ± 0.33% (w/w), 25% higher than the lowest yield obtained among investigated conditions. The extraction temperature and seed preheating showed a significant effect on FFA, on spectroscopic indices K232, K270 and ΔK values. The average values of these parameters slightly increased rising the temperature and in presence of preheating, the screw rotation speed did not affect the chemical characteristic tested. In the extraction conditions investigated no significant changes in PV and fatty acids composition of oil were observed.

Abstract
The use of plants as heterologous hosts is one of the most promising technologies for manufacturing valuable recombinant proteins. Plant seeds, in particular, constitute ideal production platforms for long-term applications requiring a steady supply of starting material, as they combine the general advantages of plants as bioreactors with the possibility of biomass storage for long periods in a relatively small volume, thus allowing manufacturers to decouple upstream and downstream processing. In the present work we have used transgenic tobacco seeds to produce large amounts of a functionally active mouse monoclonal antibody against the Hepatitis B Virus surface antigen, fused to a KDEL endoplasmic reticulum retrieval motif, under control of regulatory sequences from common bean (Phaseolus vulgaris) seed storage proteins. The antibody accumulated to levels of 6.5 mg/g of seed in the T3 generation, and was purified by Protein A affinity chromatography combined with SEC-HPLC. N-glycan analysis indicated that, despite the KDEL signal, the seed-derived plantibody bore both high-mannose and complex-type sugars that indicate partial passage through the Golgi compartment, although its performance in the immunoaffinity purification of HBsAg was unaffected. An analysis discussing the industrial feasibility of replacing the currently used tobacco leaf-derived plantibody with this seed-derived variant is also presented.
