Leaf surface characters applied to Lauraceae taxonomy in a Seasonal Forest of Southern Brazil BABT
Ceolin,Guilherme Bordignon; Rosito,Jumaida Maria; Canto-Dorow,Thais Scotti do.
The goal of this work was to test if the macro and micro morphological analysis of the leaf surface could provide vegetative diagnostic characters for some of the most common Lauraceae species in Southern Brazilian Seasonal Forests. The leaf printing technique with universal instantaneous adhesive was used for the epidermical microscopical analysis and external macroscospical analyses of leave were made. Microscopic evaluation revealed the visibility and contours of anticlinal walls of epidermical cell and stomata and shape of guard-cells. Macroscopic evaluation showed the absence or presence of characters such as hairiness, domatia and scents. The results showed that analyzed characters, together with other diagnostic characteristics, could contribute in...

The unexplored bacterial lifestyle on leaf surface. Repositório Alice
MOITINHO, M. A.; SOUZA, D. T.; CHIARAMONTE, J. B.; BONONI, L.; MELO, I. S. de; TAKETANI, R. G..
Abstract: Social interactions impact microbial communities and these relationships are mediated by small molecules. The chemical ecology of bacteria on the phylloplane environment is still little explored. The harsh environmental conditions found on leaf surface require high metabolic performances of the bacteria in order to survive. That is interesting both for scientific fields of prospecting natural molecules and for the ecological studies. Important queries about the bacterial lifestyle on leaf surface remain not fully comprehended. Does the hostility of the environment increase the populations\' cellular altruism by the production of molecules, which can benefit the whole community? Or does the reverse occur and the production of molecules related to...

UV-B resistant yeast inhabit the phyllosphere of strawberry. Repositório Alice
CASTELIANI, A. G. B.; KAVAMURA, V. N.; ZUCCHI, T. D.; SÁBER, M. L.; NASCIMENTO, R. dos S.; FRIGHETTO, R. T. S.; TAKETANI, R. G.; MELO, I. S. de.
Abstract: The increase on the worldwide influx of solar ultraviolet radiation (UV-B) has inflicted a considerable challenge, due to its deleterious effects to live beings and pose a special threat to phyllosphere communities. However, UV-B influence on epiphytic yeasts associated with agricultural crops remains limited. Main aim of the present study was to determine the effect of ultraviolet-B radiation on the epiphytic yeast populations associated with strawberry under field conditions. Thus, strawberries (Fragaria x ananassa Duchesne cv. Oso Grande) were grown under three different treatments: a) environmental UV-B, b) enhanced UV-B and c) decreased UV-B; thereafter, their yeast epiphytic populations were analyzed by T-RFLP prior to yeast isolation,...
