Soluble (S) and cell wall-bound (CW) forms of acid invertases (AIs) were partially purified from mesocarp tissue of melon (Cucumis melo L. cv. AMS) fruits and some properties of the enzymes were examined. The optimum pH values for activity were 5.5 and 4.5 for S- and CW-AI, respectively. Km values of S- and CW-AIs for sucrose were 4.2 and 1.7 mM, and those for raffinose were 20.0 and 10.5 mM, respectively. The band of a polypeptide od about 70 kDa was detected with antibodies against AI of tomato fruits (CW form) and of mung bean seedlings (S form) by immunoblot analysis. The 70-kDa polypeptide was isolated from each fraction and further analyzed by limited proteolytic digestion with Staphylococcus aureus V8 protease. The digested polypeptides generated almost identical profiles. The localization of CW-AI was also studied and it was found to be an extracellular enzyme. The activities of S- and CW-AIs per gram fresh weight increased and reached a maximum on day after anthesis, and then they decreased rapidly during maturation of fruits. The relative levels of S- and CW-AI polypeptides were correlated with the levels of activities of S-and CW-AIs. These results show that the decrease in acitvity of AI during maturation of melon fruits is due to a decline in levels of AI polypeptides in the fruits. |

Foreword It is always gratifying to be able to help advance research on native tree species and provide results to the community. Research on the occurrence of wood-producing species from native forests is strategically important for Brazil, in terms of the environment as well as the economy, and motivated the Embrapa Forestry team and its collaborators to conduct this research on Handroanthus spp. in two Brazilian states. The area where species in this genus occur is presented along with considerations about populations, growth, and structure, carrying capacity and stock managed native forests, as well as other analyses. Results from analyses of production under different forest management conditions are also presented. This data is essential not only for environmental organizations but also for the productive sector, academia, research and government institutions, and technicians that are directly or indirectly involved with management of native forests. This project is in line with Sustainable Development Goals 6, 8, 12, 15, and 17, since it addresses increased productivity and maintaining forest cover through managing native forests, involving systems that help boost efficient use of these natural resources and also promoting ecosystem conservation and biodiversity preservation. This text is the result of collaboration between different institutions and actors that work toward sustainable management of wood species in the Amazon Forest. We hope that the data provided here will fill in the gaps on this topic, with a new focus on procedures for analyzing native tree species.
