          Abstract

          El etileno es la hormona vegetal responsable de regular diferentes procesos durante la maduración de productos agrícolas, llevando a procesos de senescencia y finalmente, pérdida de valor nutricional y comercial. A través del tiempo se han desarrollado diversos retardantes químicos de la maduración para disminuir los efectos negativos del etileno en la poscosecha, los cuales actúan en las etapas de biosíntesis (aminoetoxi-vinil-glicina (AVG) y ácido aminooxiacético (AOA), acción/señalización (1-MCP)) y sales de plata como nitrato y tiosulfato de plata (STS) y compuestos que oxidan al etileno de la atmósfera (permanganato de potasio (KMnO4)). En esta revisión se describen las características principales de cada uno de los retardantes de madurez mencionados, además, se analiza con estudios científicos, el efecto que tienen estos retardantes sobre los cambios moleculares, fisiológicos, químicos y físicos durante la poscosecha de frutos, hortalizas y especies ornamentales.

          Translated abstract

          Ethylene is the plant hormone responsible for regulating various processes during the ripening of agricultural products, leading to a senescence process and, finally, to a loss of the nutritional and commercial values. Over time, different chemical maturation retardants have been developed to decrease the negative effects of ethylene, which act on the stages of biosynthesis (aminoethoxy-vinyl-glycine (AVG) and aminooxyacetic acid (AOA), action/signaling (1-methylcyclopropene (1-MCP)) and silver salts, such as nitrate and silver thiosulfate (STS) and compounds that oxidize the ethylene of the atmosphere (potassium permanganate (KMnO4). In this review, the main characteristics of each chemical retardant are discussed along with the scientific studies on the effects of these retardants on the molecular, physiological, chemical and physical changes during the postharvest of fruits, vegetables and ornamental species.

              Ethylene signal transduction.

              The phytohormone ethylene is a key regulator of plant growth and development. Components of the pathway for ethylene signal transduction were identified by genetic approaches in Arabidopsis and have now been shown to function in agronomically important plants as well. This review focuses on recent advances in our knowledge on ethylene signal transduction, in particular on recently proposed components of the pathway, on the interaction between the pathway components and on the roles of transcriptional and post-transcriptional regulation in ethylene signalling. Data indicate that the site of ethylene perception is at the endoplasmic reticulum and point to the importance of protein complexes in mediating the initial steps in ethylene signal transduction. The expression level of pathway components is regulated by both transcriptional and post-transcriptional mechanisms, degradation of the transcription factor EIN3 being a primary means by which the sensitivity of plants to ethylene is regulated. EIN3 also represents a control point for cross-talk with other signalling pathways, as exemplified by the effects of glucose upon its expression level. Amplification of the initial ethylene signal is likely to play a significant role in signal transduction and several mechanisms exist by which this may occur based on properties of known pathway components. Signal output from the pathway is mediated in part by carefully orchestrated changes in gene expression, the breadth of these changes now becoming clear through expression analysis using microarrays.
