Plant transformation is an important tool with many applications in modern plant biology. Although this technique is primarily used to produce superior crop varieties, it is also being utilized to answer basic questions concerning gene function and regulation in contemporary functional genomics research. In our laboratory, we have established a transformation system for Hypericum perforatum . This protocol invo...
We have developed particle bombardment-mediated transformation procedure for Hypericum perforatum L. (St. John’s wort), an important medicinal species that remains highly recalcitrant towards Agrobacterium-mediated transformation. Among the major transformation techniques evaluated in the present study (Agrobacterium tumefaciens-, A. rhizogenes- and biolistics-mediated), particle-bombardment-mediated gene trans...
Diabetes mellitus (DM) é uma doença progressiva que apresenta complicações freqüentes, em especial a infecção nos pés. Realizamos um estudo prospectivo com 141 pacientes com DM e úlceras infectadas nos pés, conduzido no Centro Integrado de Diabetes e Hipertensão da UFC no período de março/2000 a novembro/2001. A maioria apresentava infecção avaliada como graus I e II da classificação de Wagner. As amostras fora...
