Influence of the antibiotic timentin on plant regeneration of tomato (Lycopersi...
Costa, M. G. C.; Nogueira, F. T. S.; Figueira, M. L.; Otoni, W. C.; Brommonschenkel, S. H.; Cecon, P. R.Cotyledon explants of tomato (Lycopersicon esculentum Mill. cvs 'Santa Clara', 'Firme' mutant, 'IPA-5' and 'IPA-6') were excised from 8- to 10-day-old in vitro-grown seedlings. Four different shoot induction media supplemented with timentin (300 mg l–1) were screened. When cotyledon explants were cultured on MS-based medium with 1.0 mg l–1 zeatin plus 0.1 mg l–1 IAA and supplemented with timentin, higher regen...
Regenerative potential, metabolic profile, and genetic stability of Brachypodiu...
Mamedes-Rodrigues, T. C.; Batista, D. S.; Vieira, N. M.; Matos, E. M.; Fernandes, D.; Nunes-Nesi, A.; Cruz, C. D.; Viccini, L. F.; Nogueira, F. T. S.Brachypodium distachyon, a model species for forage grasses and cereal crops, has been used in studies seeking improved biomass production and increased crop yield for biofuel production purposes. Somatic embryogenesis (SE) is the morphogenetic pathway that supports in vitro regeneration of such species. However, there are gaps in terms of studies on the metabolic profile and genetic stability along successive ...

Rodrigues, T. C. Mamedes; Batista, D. S.; Napoleão, T. A.; Cruz, A. C. F.; Fortini, E. A.; Nogueira, F. T. S.; Romanel, E.; Otoni, W. C.Light quality is perceived by plants through several receptors and generates diverse morphological, metabolic, and genetic responses. In this study, the identification of new putative lignocellulosic genes, expression analysis, as well as morphological, anatomical, enzymatic, and chemical characteristics were investigated in Brachypodium distachyon plants grown in vitro under different light treatments. Treatme...
