ABSTRACT.
Grapefruits are among the citrus species more sensitive to cold and develop chilling injury symptoms during prolonged postharvest storage at temperatures lower than 8 C?10 C. The plant hormone ethylene has been described either to protect or potentiate chilling injury development in citrus whereas little is known about transcriptional regulation of ethylene biosynthesis, perception and response during cold storage and how the hormone is regulating its own perception and signaling cascade. Then, the objective of the present study was to explore the transcriptional changes in the expression of ethylene biosynthesis, receptors and response genes during cold storage of the white Marsh and the red Star Ruby grapefruits. The effect of the ethylene action inhibitor, 1-MCP, was evaluated to investigate the involvement of ethylene in the regulation of the genes of its own biosynthesis and perception pathway. Ethylene production was very low at the harvest time in fruits of both varieties and experienced only minor changes during storage. By contrast, inhibition of ethylene perception by 1-MCP markedly induced ethylene production, and this increase was highly stimulated during shelf-life at 20 C, as well as transcription of ACS and ACO. These results support the autoinhibitory regulation of ethylene in grapefruits, which acts mainly at the transcriptional level of ACS and ACO genes. Moreover, ethylene receptor1 and ethylene receptor3 were induced by cold while no clear role of ethylene was observed in the induction of ethylene receptors. However, ethylene appears to be implicated in the transcriptional regulation of ERFs both under cold storage and shelf-life. MenosABSTRACT.

El INTA viene desarrollando desde del año 2006 proyectos institucionales de domesticación y mejoramiento genético de especies forestales de alto valor, en colaboración con universidades, productores privados y organismos públicos nacionales y provinciales con incumbencia en la actividad forestal, de investigación o vinculados al desarrollo territorial. Las especies objeto de estos proyectos se caracterizan por ser productoras de madera de alto valor, en general emblemáticas desde el punto de vista cultural y de importancia desde el punto de vista ambiental. El objetivo común de dichos proyectos es el desarrollo de materiales de propagación, tecnología de cultivo desde el vivero hasta la plantación, conocimientos sobre la distribución, diversidad genética y adaptación de sus poblaciones naturales dirigidos al uso y la conservación. Se identifican tres destinos principales de este desarrollo tecnológico: 1) Plantaciones forestales con destino a la producción de madera para aserrado. 2) Sistemas de producción consociados, silvopastoril y agroforestal y 3)
Restauración, enriquecimiento y remediación ecosistémica. |
