Abstract Background Sugarcane is an increasingly economically and environmentally important C4 grass, used for the production of sugar bioethanol, a low-carbon emission fuel. originated from crosses Saccharum species noted its unique capacity to accumulate high amounts sucrose in stems. Environmental stresses limit enormously sugarcane productivity worldwide. To investigate transcriptome changes response environmental inputs that alter yield we cDNA microarrays profile expression 1,545 genes...
In sugarcane fields, colonization of the stalk by opportunistic fungi usually occurs after caterpillar Diatraea saccharalis attacks plant. Plants respond to insect attack inducing and accumulating a large set defense proteins. Two homologues barley wound-inducible protein (BARWIN), proteins SUGARWIN1 SUGARWIN2, have been identified in an silico analysis. Antifungal properties described for number BARWIN homologues. We report that SUGARWIN::green fluorescent fusion is located endoplasmic...
Resistance to Xylella fastidiosa was evaluated in 264 hybrids of crosses between Murcott tangor (Citrus reticulata × Citrus sinensis) and Pera sweet orange (C. under field conditions. Uninfected were grafted with buds collected from plants infected X. fastidiosa, forming a plant two scions (i.e., hybrid branches branches). From these plants, we chose 10 genotypes three biological replicates. We gene expression, bacterial multiplication, citrus variegated chlorosis (CVC) symptom development...
Sugarcane’s (Saccharum spp.) response to Diatraea saccharalis (F.) (Lepidoptera: (Crambidae) herbivory was investigated using a macroarray spotted with 248 sugarcane Expressed Sequence Tags (ESTs) encoding serine peptidase inhibitors, peptidases. and Clp protease system subunits. Our results showed that after nine hours of herbivory, 13 genes were upregulated downregulated. Among the genes, similar inhibitors four Bowman-Birk Inhibitors (BBIs). Phylogenetic analysis revealed these sequences...
The influence of foliar glandular trichomes on developmental biology the potato leafhopper, Empoasca fabae (Harris) (Homoptera: Cicadellidae), was examined by selective removal resistant and susceptible germplasm comprising two trichome-bearing genotypes (PI 473331 PI 473334) wild potato, Solanum berthaultii (Hawkes), interspecific hybrids S. with tuberosum L. (Q174-2 NY123), commercial cultivars ('Elba' 'Allegany'). Adult mortality affected, whereas nymphal emergence unaffected trichome...
Com o objetivo de identificar as espécies formigas cortadeiras que existem na região da Depressão Central do Estado Rio Grande Sul, verificar sua predominância e distribuição geográfica, realizou-se um levantamento em 51 municípios. Foram coletadas 40 amostras cada município no segundo semestre 1999. A identificação das a interpretação dos dados foi realizada Departamento Fitossanidade Faculdade Agronomia "Eliseu Maciel" Universidade Federal Pelotas. Na análise 2.058 formigas, constatou-se...
Survival of nymphs and adult males females potato leafhopper, Empoasca fabae (Harris), on six (Solanum spp.) genotypes with varied levels resistance was evaluated related to type, density, droplet/head size foliar glandular trichomes. greater Solanum tuberosum cultivars (‘Allegany’ ‘Elba’) compared accessions the wild S. berthaultii (PI 473331 PI 473334). The barrier provided by trichomes may affect survival E. restricting nymph feeding. most pubescent host, bearing type A B unsuitable host...
