A chloroplast-derived Toxoplasma gondiiGRA4 antigen used as an oral vaccine protects against toxoplasmosis in mice
The parasitic protozoan Toxoplasma gondii, the causal agent of toxoplasmosis, can infect most mammals and birds. In human medicine, T. gondii can cause complications in pregnant women and immunodeficient individuals, while ... -
Functional improvement of human cardiotrophin 1 produced in tobacco chloroplasts by co-expression with plastid thioredoxin m
Human cardiotrophin 1 (CT1), a cytokine with excellent therapeutic potential, was previously expressed in tobacco chloroplasts. However, the growth conditions required to reach the highest expression levels resulted in an ... -
The fusion of Toxoplasma gondii SAG1 vaccine candidate to Leishmania infantum heat shock protein 83-kDa improves expression levels in tobacco chloroplasts
Chloroplast transformation technology has emerged as an alternative platform offering many advantages over nuclear transformation. SAG1 is the main surface antigen of the intracellular parasite Toxoplasma gondii and a ... -
Heat treatment alleviates the growth and photosynthetic impairment of transplastomic plants expressing Leishmania infantum Hsp83-Toxoplasma gondii SAG1 fusion protein
Previously, we showed that transplastomic tobacco plants expressing the LiHsp83-SAG1 fusion protein displayed a chlorotic phenotype and growth retardation, while plants expressing the SAG1 and GRA4 antigens alone did not. ... -
Human papillomavirus L1 protein expressed in tobacco chloroplasts self-assembles into virus-like particles that are highly immunogenic
Cervical cancer is the second most prevalent cancer in women worldwide. It is linked to infection with human papillomavirus (HPV). As the virus cannot be propagated in culture, vaccines based on virus‐like particles have ... -
Identification of new antifungal metabolites produced by the yeast Metschnikowia pulcherrima involved in the biocontrol of postharvest plant pathogenic fungi
Several strains of the yeast Metschnikowia pulcherrima exhibit strong antagonistic activity against postharvest pathogens and may have broad biotechnological potential as biocontrol agents. However, the nature and ... -
Increased bioethanol production from commercial tobacco cultivars overexpressing thioredoxin f grown under field conditions
Bioethanol is mainly produced from food crops such as sugar cane and maize while it has been held partly responsible for the rise of food commodity prices. Tobacco, integrated in biorefinery facilities for the extraction ... -
Metschnikowia pulcherrima as an efficient biocontrol agent of Botrytis cinerea infection in apples: unraveling protection mechanisms through yeast proteomics
The results obtained in this study show that the Mp-30 strain of Metschnikowia pulcherrima is able to completely prevent Botrytis cinerea infection in apples, which is a major postharvest disease of fruits throughout the ... -
New in vivo approach to broaden the thioredoxin family interactome in chloroplasts
Post-translational redox modifications provide an important mechanism for the control of major cellular processes. Thioredoxins (Trxs), which are key actors in this regulatory mechanism, are ubiquitous proteins that catalyse ... -
NTRC and thioredoxin f overexpression differentially induces starch accumulation in tobacco leaves
Thioredoxin (Trx) f and NADPH-dependent Trx reductase C (NTRC) have both been proposed as major redox regulators of starch metabolism in chloroplasts. However, little is known regarding the specific role of each protein ... -
Overexpression of thioredoxin m in chloroplasts alters carbon and nitrogen partitioning in tobacco
In plants, there is a complex interaction between carbon (C) and nitrogen (N) metabolism, and its coordination is fundamental for plant growth and development. Here, we studied the influence of thioredoxin (Trx) m on C and ... -
Overexpression of thioredoxin m in tobacco chloroplasts inhibits the protein kinase STN7 and alters photosynthetic performance
The activity of the protein kinase STN7, involved in phosphorylation of the light-harvesting complex II (LHCII) proteins, has been reported as being co-operatively regulated by the redox state of the plastoquinone pool ... -
Physiological performance of transplastomic tobacco plants overexpressing aquaporin AQP1 in chloroplast membranes
The leaf mesophyll CO2 conductance and the concentration of CO2 within the chloroplast are major factors affecting photosynthetic performance. Previous studies have shown that the aquaporin NtAQP1 (which localizes to the ... -
Plant growth-promoting traits of yeasts isolated from Spanish vineyards: benefits for seedling development
It is known that some microorganisms can enhance plant development. However, the use of yeasts as growth-promoting agents has been poorly investigated. The aim of this study was the characterisation of a collection of 69 ... -
Post-harvest light treatment increases expression levels of recombinant proteins in transformed plastids of potato tubers
Plastid genetic engineering represents an attractive system for the production of foreign proteins in plants. Although high expression levels can be achieved in leaf chloroplasts, the results for non-photosynthetic plastids ... -
Potato genetic resources in Spain
(International Plant Genetic Resources Institute, 2001) Contribución a congreso / Biltzarrerako ekarpenaPlant genetic resources activities in Spain are globally organized by the Instituto Nacional de Investigación Agraria (INIA) and in particular by one of its institutes, Centro de Recursos Fitogenéticos (CRF). Collections ... -
Successful biocontrol of major postharvest and soil-borne plant pathogenic fungi by antagonistic yeasts
Fungal pathogens are the main biotic burden of productivity for economically important crops under field, greenhouse or postharvest conditions. The discovery and development of new environmental-friendly solutions, such ... -
Towards understanding of fungal biocontrol mechanisms of different yeasts antagonistic to Botrytis cinerea through exometabolomic analysis
There is increased interest in research on yeasts as potential phytopathogen biocontrol agents due to increasing restrictions in the use of chemical pesticides. Yeast strains from a range of genera and species have been ...
