1. Studies on soil seed bank, rescue of shoots and dynamics of the landscape for forest restoration purposes, Carandaí, MG / Estudos sobre banco de sementes do solo, resgate de plântulas e dinâmica da paisagem para fins de restauração florestal, Carandaí, MG
Observando-se a necessidade de novas metodologias que permitam que áreas restauradas se consolidem no tempo, realizaram-se alguns estudos ecológicos em uma propriedade rural, localizada no município de Carandaí, Estado de Minas Gerais, Brasil, os quais foram organizados em capítulos: 1) caracterização dos fragmentos de Floresta Estacional Semidecidual

2. Autochthonous and Allochthonous seed bank, seedling rescue and native vegetation planting at Intermontes farm, Ribeirão Grande-SP- Brazil. / Banco de sementes autóctone e alóctone, resgate de plantas e plantio de vegetação nativa na fazenda Intermontes, município de Ribeirão Grande, SP.
O acúmulo significativo de conhecimento sobre a ecologia de restauração nos últimos anos tem conduzido a mudanças na orientação dos programas de manejo e restauração florestal. A escolha ou criação de um modelo de restauração é um processo em constante aprimoramento, exigindo a necessidade de estudos que não apenas diminuam os custos envolvido

3. AUX1 Promotes Lateral Root Formation by Facilitating Indole-3-Acetic Acid Distribution between Sink and Source Tissues in the Arabidopsis Seedling
Arabidopsis root architecture is regulated by shoot-derived signals such as nitrate and auxin. We report that mutations in the putative auxin influx carrier AUX1 modify root architecture as a result of the disruption in hormone transport between indole-3-acetic acid (IAA) source and sink tissues. Gas chromatography–selected reaction monitoring–mass spect

4. Genetic and developmental control of nuclear accumulation of COP1, a repressor of photomorphogenesis in Arabidopsis.
Using a beta-glucuronidase (GUS) reporter-COP1 fusion transgene, it was shown previously that Arabidopsis COP1 acts within the nucleus as a repressor of seedling photomorphogenic development and that high inactivation of COP1 was accompanied by a reduction of COP1 nuclear abundance (A.G. von Arnim, X.-W. Deng [1994] Cell 79: 1035-1045). Here we report that t

5. An Arabidopsis indole-3-butyric acid-response mutant defective in PEROXIN6, an apparent ATPase implicated in peroxisomal function
Genetic evidence suggests that plant peroxisomes are the site of fatty acid β-oxidation and conversion of the endogenous auxin indole-3-butyric acid (IBA) to the active hormone indole-3-acetic acid. Arabidopsis mutants that are IBA resistant and sucrose dependent during early development are likely to have defects in β-oxidation of both IBA and fatty acids

6. Trehalose Mediated Growth Inhibition of Arabidopsis Seedlings Is Due to Trehalose-6-Phosphate Accumulation1[w]
Trehalose-6-phosphate (T6P) is required for carbon utilization during Arabidopsis development, and its absence is embryo lethal. Here we show that T6P accumulation inhibits seedling growth. Wild-type seedlings grown on 100 mm trehalose rapidly accumulate T6P and stop growing, but seedlings expressing Escherichia coli trehalose phosphate hydrolase develop nor

7. Canonical histidine kinase activity of the transmitter domain of the ETR1 ethylene receptor from Arabidopsis is not required for signal transmission
Ethylene signaling in plants is mediated by a family of receptors related to bacterial two-component histidine kinases. Of the five members of the Arabidopsis ethylene receptor family, members of subfamily I (ETR1 and ERS1) contain completely conserved histidine kinase domains, whereas members of subfamily II (ETR2, EIN4, and ERS2) lack conserved residues th

8. CSN1 N-Terminal–dependent Activity Is Required for Arabidopsis Development But Not for Rub1/Nedd8 Deconjugation of Cullins: A Structure-Function Study of CSN1 Subunit of COP9 Signalosome
The COP9 signalosome (CSN) is a multifunctional protein complex essential for arabidopsis development. One of its functions is to promote Rub1/Nedd8 deconjugation from the cullin subunit of the Skp1-cullin-F-box ubiquitin ligase. Little is known about the specific role of its eight subunits in deneddylation or any of the physiological functions of CSN. In th
