TOMATO IS ONE OF THE MOST IMPORTANT VEGETABLE CROPS WORLDWIDE THAT IS MARKETED BOTH FRESH AND PROCESSED. WHILE FRESH TOMATO MUST HAVE ORGANOLEPTIC CHARACTERISTICS THAT SATISFY THE CONSUMER, TOMATO FOR INDUSTRIAL USE MUST ALSO HAVE APPROPRIATE PROPERTIES FOR THIS PURPOSE. THE MATURATION OF THE FRUIT IS A COMPLEX PROCESS, PROGRAMMED AT A GENETIC LEVEL, THAT INVOLVES A SERIES OF BIOCHEMICAL PROCESSES THAT MODIFY ITS TEXTURE, PIGMENTATION, FLAVOR AND AROMA. THESE CHANGES GIVE THE FRUIT THE OPTIMAL CHARACTERISTICS FOR CONSUMPTION. HOWEVER, IN THE FINAL STAGES OF MATURATION THERE IS A RAPID SOFTENING OF THE FRUIT AND AN INCREASE IN SUSCEPTIBILITY TO MICROBIAL INFECTIONS THAT CAUSE ITS RAPID DETERIORATION. OTHER RELEVANT CHARACTERISTICS OF THE FRUIT ARE RELATED TO POST-HARVEST HANDLING AND MARKETING. ALL THESE ASPECTS ARE IMPORTANT OBJECTIVES IN PROGRAMMES TO IMPROVE THE QUALITY OF THE FRUIT. ANOTHER POINT TO CONSIDER IN RELATION TO THE CULTIVATION OF TOMATO IS THE HIGH SUSCEPTIBILITY OF THE PLANT TO DIFFERENT TYPES OF STRESS WITH THE CONSEQUENT ECONOMIC IMPACT. IN PARTICULAR, PEST CONTROL THROUGH THE USE OF PESTICIDES INCREASES THE COST OF PRODUCTION AND ALSO REPRESENTS A RISK FACTOR FOR CONSUMERS AND THE ENVIRONMENT. THE DEVELOPMENT OF PEST-RESISTANT VARIETIES IS THEREFORE A MAJOR CHALLENGE IN THE CONTEXT OF SUSTAINABLE AGRICULTURE. UNLIKE OTHER PLANT SPECIES, THE TOMATO, ALONG WITH OTHER SPECIES OF THE GENUS SOLANUM, HAS AN ATYPICAL COMPOSITION IN THE CONTENT AND PROFILE OF STEROLS, BEING TO HIGHLIGHT THE EXTRAORDINARILY HIGH LEVELS OF CONJUGATED STEROLS. MOREOVER, DURING THE RIPENING OF THE FRUIT THERE ARE VERY IMPORTANT CHANGES IN THE LEVELS AND RELATIVE PROPORTIONS OF THE FREE AND CONJUGATED STEROLS. THE BIOLOGICAL AND EVOLUTIONARY SIGNIFICANCE OF THE PECULIAR METABOLISM OF STEROLS IN TOMATO IS TOTALLY UNKNOWN. RECENT STUDIES INDICATE THAT STEROLS PLAY AN ESSENTIAL ROLE IN PLANT GROWTH AND DEVELOPMENT AND IN THEIR RESPONSE TO DIFFERENT TYPES OF STRESS. BASED ON THESE OBSERVATIONS, AND TAKING INTO ACCOUNT THAT THE KNOWLEDGE OF ENZYMES INVOLVED IN THE SYNTHESIS OF CONJUGATED STEROLS IS STILL VERY LIMITED, A PROJECT AIMED AT STUDYING THE METABOLISM OF THESE COMPOUNDS IN TOMATO IS PROPOSED. ON THE ONE HAND, IT IS PROPOSED TO IDENTIFY AND CHARACTERISE THE ENZYMES INVOLVED IN THE SYNTHESIS OF CONJUGATED STEROLS AND TO CLONE THE CORRESPONDING GENES. THIS WILL ALLOW TO ADDRESS GENETIC APPROACHES BASED ON THE GENERATION OF TRANSGENIC PLANTS AND THE SELECTION OF MUTANT PLANTS AND WITH ALELICAS VARIANTS OF THE GENES OF INTEREST (OBTAINED BY TILLING AND ECOTILLING) WITH CONTENTS AND PROFILES OF MODIFIED STEROLS. THE AVAILABILITY OF THESE PLANTS WILL ALLOW TO EVALUATE THE ROLE OF SPECIFIC STEROLS IN PROCESSES RELATED BOTH TO THE GROWTH AND DEVELOPMENT OF THE PLANT AND ITS RESPONSE TO STRESS AND TO THE MATURATION OF THE FRUIT, THE RESPONSE TO COLD DAMAGE AND SUSCEPTIBILITY TO THE ATTACK BY PATHOGENS. THAT IS WHY THE KNOWLEDGE GENERATED IN THE PROJECT SHOULD CONTRIBUTE NOT ONLY TO A BETTER UNDERSTANDING OF THE BIOLOGICAL FUNCTION OF STEROLS IN TOMATO BUT ALSO TO THE DEVELOPMENT OF NEW STRATEGIES AIMED AT IMPROVING THE QUALITY OF THE FRUIT AND TOLERANCE TO DIFFERENT TYPES OF STRESS.

    summary
    EL TOMATE ES UNO DE LOS CULTIVOS VEGETALES MAS IMPORTANTES A NIVEL MUNDIAL QUE SE COMERCIALIZA TANTO FRESCO COMO PROCESADO. MIENTRAS QUE EL TOMATE FRESCO DEBE TENER UNAS CARACTERISTICAS ORGANOLEPTICAS QUE SATISFAGAN AL CONSUMIDOR, EL TOMATE PARA USO INDUSTRIAL DEBE TENER ADEMAS PROPIEDADES ADECUADAS A TAL FIN. LA MADURACION DEL FRUTO ES UN PROCESO COMPLEJO, PROGRAMADO A NIVEL GENETICO, QUE COMPORTA UNA SERIE DE PROCESOS BIOQUIMICOS QUE MODIFICAN SU TEXTURA, PIGMENTACION, SABOR Y AROMA. ESTOS CAMBIOS CONFIEREN AL FRUTO LAS CARACTERISTICAS OPTIMAS PARA EL CONSUMO. NO OBSTANTE, EN LAS ETAPAS FINALES DE LA MADURACION SE PRODUCE UN RAPIDO ABLANDAMIENTO DEL FRUTO Y UN INCREMENTO DE LA SUSCEPTIBILIDAD A LAS INFECCIONES MICROBIANAS QUE PROPICIAN SU RAPIDO DETERIORO. OTRAS CARACTERISTICAS RELEVANTES DEL FRUTO ESTAN RELACIONADAS CON LA MANIPULACION POSTCOSECHA Y SU COMERCIALIZACION. TODOS ESTOS ASPECTOS CONSTITUYEN OBJETIVOS IMPORTANTES EN LOS PROGRAMAS DE MEJORA DE CALIDAD DEL FRUTO. OTRO PUNTO A TENER EN CUENTA EN RELACION CON EL CULTIVO DEL TOMATE ES LA ELEVADA SUSCEPTIBILIDAD DE LA PLANTA A DISTINTOS TIPOS DE ESTRES CON LA CONSIGUIENTE REPERCUSION ECONOMICA. EN PARTICULAR EL CONTROL DE PLAGAS MEDIANTE EL USO DE PESTICIDAS INCREMENTA EL COSTE DE PRODUCCION Y REPRESENTA ADEMAS UN FACTOR DE RIESGO PARA LOS CONSUMIDORES Y EL MEDIOAMBIENTE. POR ELLO EL DESARROLLO DE VARIEDADES RESISTENTES A PLAGAS CONSTITUYE UN RETO IMPORTANTE EN EL CONTEXTO DE LA AGRICULTURA SOSTENIBLE. A DIFERENCIA DEL RESTO DE ESPECIES VEGETALES, EL TOMATE, JUNTO CON OTRAS ESPECIES DEL GENERO SOLANUM, PRESENTA UNA COMPOSICION ATIPICA EN EL CONTENIDO Y PERFIL DE ESTEROLES, SIENDO DE DESTACAR LOS NIVELES EXTRAORDINARIAMENTE ELEVADOS DE ESTEROLES CONJUGADOS. ADEMAS, DURANTE LA MADURACION DEL FRUTO SE PRODUCEN CAMBIOS MUY IMPORTANTES EN LOS NIVELES Y PROPORCIONES RELATIVAS DE LOS ESTEROLES LIBRES Y CONJUGADOS. LA SIGNIFICACION BIOLOGICA Y EVOLUTIVA DEL PECULIAR METABOLISMO DE LOS ESTEROLES EN EL TOMATE ES TOTALMENTE DESCONOCIDA. ESTUDIOS RECIENTES INDICAN QUE LOS ESTEROLES JUEGAN UN PAPEL ESENCIAL EN EL CRECIMIENTO Y DESARROLLO DE LAS PLANTAS Y EN SU RESPUESTA A DIFERENTES TIPOS DE ESTRES. A PARTIR DE ESTAS OBSERVACIONES, Y TENIENDO EN CUENTA QUE EL CONOCIMIENTO SOBRE LAS ENZIMAS IMPLICADAS EN LA SINTESIS DE LOS ESTEROLES CONJUGADOS ES TODAVIA MUY LIMITADO, SE PROPONE UN PROYECTO ORIENTADO AL ESTUDIO DEL METABOLISMO DE DICHOS COMPUESTOS EN EL TOMATE. POR UNA PARTE, SE PROPONE IDENTIFICAR Y CARACTERIZAR LAS ENZIMAS IMPLICADAS EN LA SINTESIS DE ESTEROLES CONJUGADOS Y CLONAR LOS GENES CORRESPONDIENTES. ELLO PERMITIRA ABORDAR APROXIMACIONES GENETICAS BASADAS EN LA GENERACION DE PLANTAS TRANSGENICAS Y LA SELECCION DE PLANTAS MUTANTES Y CON VARIANTES ALELICAS DE LOS GENES DE INTERES (OBTENIDAS MEDIANTE TILLING Y ECOTILLING) CON CONTENIDOS Y PERFILES DE ESTEROLES MODIFICADOS. LA DISPONIBILIDAD DE ESTAS PLANTAS PERMITIRA EVALUAR EL PAPEL DE ESTEROLES ESPECIFICOS EN PROCESOS RELACIONADOS TANTO CON EN EL CRECIMIENTO Y DESARROLLO DE LA PLANTA Y SU RESPUESTA A ESTRES COMO CON LA MADURACION DEL FRUTO, LA RESPUESTA AL DAÑO POR FRIO Y LA SUSCEPTIBILIDAD AL ATAQUE POR PATOGENOS. ES POR ELLO QUE LOS CONOCIMIENTOS GENERADOS EN EL PROYECTO DEBERIAN CONTRIBUIR NO SOLO A UNA MEJOR COMPRENSION DE LA FUNCION BIOLOGICA DE LOS ESTEROLES EN EL TOMATE SINO TAMBIEN AL DESARROLLO DE NUEVAS ESTRATEGIAS ORIENTADAS A LA MEJORA DE LA CALIDAD DEL FRUTO Y DE LA TOLERANCIA A DISTINTOS TIPOS DE ESTRES.
