“…In fact, the area under Eucalyptus cultivation has increased 30 times in roughly 60 years, especially in tropical and subtropical countries [ 13 ]. Many Eucalyptus species like E. sargentii , E. camaldulensis , E. loxophleba , E. spathulate , E. agrophloia and E. neglecta show capacity to tolerate salinity [ 14 , 15 , 16 ] and have been used widely to explore salinity tolerance mechanisms in plants.…”

In the face of rising salinity along coastal regions and in irrigated areas, molecular breeding of tolerant crops and reforestation of exposed areas using tolerant woody species is a two-way strategy. Thus, identification of tolerant plants and of existing tolerance mechanisms are of immense value. In the present study, three Eucalyptus ecotypes with potentially differential salt sensitivity were compared. Soil-grown Eucalyptus plants were exposed to 80 and 170 mM NaCl for 30 days. Besides analysing salt effects on ionic/osmotic balance, and hydrolytic enzymes, plants were compared for dynamics of light-induced redox changes in photosynthetic electron transport chain (pETC) components, namely plastocyanin (PC), photosystem I (PSI) and ferredoxin (Fd), parallel to traditional chlorophyll a fluorescence-based PSII-related parameters. Deconvoluted signals for PC and Fd from PSI allowed identification of PC and PSI as the prime salinity-sensitive components of pETC in tested Eucalyptus species. Eucalyptus loxophleba portrayed efficient K+-Na+ balance (60–90% increased K+) along with a more dynamic range of redox changes for pETC components in old leaves. Young leaves in Eucalyptus loxophleba showed robust endomembrane homeostasis, as underlined by an increased response of hydrolytic enzymes at lower salt concentration (~1.7–2.6-fold increase). Findings are discussed in context of salinity dose dependence among different Eucalyptus species.

Resumo: O presente trabalho objetivou estabelecer uma nova linha de estudo sobre desenvolvimento de plantas através da interpretação de seus estados entrópicos. Estes no Eucalyptus camaldulensis. cultivado in vitro em diferentes condições de deficiência hídrica, foram avaliados através de sua produção de matéria seca utilizando-se as funções de entropia de Clausius e Shannon. O material submetido à deficiência hídrica obedeceu ao segundo princípio da termodinâmica, comportando-se como uma estrututa dissipativa. A medida que houve um aumento na produção de entropia houve uma menor diferenciação dos tecidos foliares, ou seja, uma redução do nível de organização da planta. Palavras-chave: entropia, informação, organização, Euca/yptus camaldulensis, cultura de tecidos, estresse hídrico. Abstract: (Entropy, information, and water stress in Eucalyptus camaldulensis in vitro) This work purposed develop a new approach about the plant development through interpretation of yours entropic states. The Eucalyptus camaldulensis entropic states, in vitro cultivated under water deficit, were evaluated through dry matter production utilizing the Clausius and Shannon functions. The material under water deficit followed to second iaw of thermodynamics like a dissipative structure. Whereas the entropic production increased the leaves tissues diffrentiation decreased, this is, the piant organization reduction.
