Resumen
The ability of plants to cope with frost events relies on the physiological and molecular responses triggered by cold temperatures. This process, named acclimation, involves reprogramming gene expression in order to adjust metabolism. Planted Eucalyptus species are highly productive but most of them are frost sensitive. However, acclimation process varies among species and environmental conditions, promoting more or less frost damage in young plantations [ver mas...]

dc.description.abstractThe ability of plants to cope with frost events relies on the physiological and molecular responses triggered by cold temperatures. This process, named acclimation, involves reprogramming gene expression in order to adjust metabolism. Planted Eucalyptus species are highly productive but most of them are frost sensitive. However, acclimation process varies among species and environmental conditions, promoting more or less frost damage in young plantations of frost-prone areas. To identify metabolites and proteins responsible for these differences, two acclimation regimes were imposed to seedling of Eucalyptus grandis Hill ex Maiden (Eg), Eucalyptus dunnii Maiden (Ed) and Eucalyptus benthamii Maiden Cambage (Eb), and leaves submitted to biochemical and molecular analyses. Further, seedlings were used for simulated frosts in order to test the acclimation status effect on frost tolerance. Eb showed higher frost tolerance than Ed and Eg under control and acclimation scenarios, possibly due to its higher accumulation of phenolics, anthocyanins and soluble sugars as well as lower levels of photosynthetic pigments and related proteins. Also, a rise in frost tolerance and in osmoprotectants and antioxidants was observed for all the species due to cold acclimation treatment. Interestingly, metabolic profiles differed among species, suggesting different mechanisms to endure frosts and, probably, different requirements for cold acclimation. Shotgun proteomics reinforced differences and commonalities and supported metabolome observations. An in depth understanding of these responses could help to safeguard planted forests productivity through breeding of tolerant genetic material.eng
