13. Relationship between leaf stages and epistasis for resistance to Stagonospora nodorum in durum wheat
Ten varieties and eight generations (2F1, 2F2, 2B1 and 2B2) of durum wheat derived from two crosses were evaluated for resistance to natural infection by Stagonospora nodorum blotch (SNB) at the 2-3 and 6-7 leaf stages at two sites over two years. There were significant differences in the incidence of SNB between leaf stages in most of the wheat varieties, w

14. In silico identification of known osmotic stress responsive genes from Arabidopsis in soybean and Medicago
Plants experience various environmental stresses, but tolerance to these adverse conditions is a very complex phenomenon. The present research aimed to evaluate a set of genes involved in osmotic response, comparing soybean and medicago with the well-described Arabidopsis thaliana model plant. Based on 103 Arabidopsis proteins from 27 categories of osmotic s

15. Identificação, caracterização molecular e avaliação da expressão do gene de uma proteína elicitora de defesa de trichoderma spp. / Identification, molecular characterization and evaluation of gene expression of a protein elicitors of defense of Trichoderma spp.
Species of the genus Trichoderma have been used as biocontrol agents against different pathogens. The mechanisms employed by Trichoderma species against these pathogens ranging from competition for nutrients, production of non-volatile and volatile antibiotics in the production of hydrolytic enzymes, in a mechanism denominated mycoparasitism. In addition to

17. Fotossíntese, crescimento e composição química em plantas de Theobroma cacao L. submetidas a diferentes concentrações de silicato de potássio e sua interação com insetos-praga / Photosynthesis, growth and chemical composition in plants of Theobroma cacao L. subjected to different concentrations of potassium silicate and its interaction with insect-pests
The control of insect pests through the use of pesticides, is still the most method used in the cultivation of cocoa. However, due to environmental issues, there need to seek new alternatives of control less harmful the environment and to humans. In this context, silicon is a nutrient that is being used in various cultures, due to its beneficial effects on p

18. In silico identification of coffee genome expressed sequences potentially associated with resistance to diseases.
Sequences potentially associated with coffee resistance to diseases were identified by in silico analyses using the database of the Brazilian Coffee Genome Project (BCGP). Keywords corresponding to plant resistance mechanisms to pathogens identified in the literature were used as baits for data mining. Expressed sequence tags (ESTs) related to each of these

20. Differential gene expression, induced by salicylic acid and Fusarium oxysporum f. sp. lycopersici infection, in tomato.
The objective of this work was to determine the transcript profile of tomato plants (Lycopersicon esculentum Mill.), during Fusarium oxysporum f. sp. lycopersici infection and after foliar application of salicylic acid. The suppression subtractive hybridization (SSH) technique was used to generate a cDNA library enriched for transcripts differentially expr

21. Interação molecular planta-nematóide.
ABSTRACT: The endoparasitic sedentary phytonematodes of genera Heterodera, Globodera (known as cyst nematodes, CN) and Meloidogyne (the root-knot nematodes, RKN) are major crop phytopathogens, causing estimated losses of US$ 125 billion annually in the world. These plant-parasitic nematodes share some parasitism mechanisms, which ensure host-tissue invasion

22. Histopatologia das reações de resistência de hospedeiro e de não-hospedeiro em interações Puccinia triticina x Poaceae / Histopathology of resistance reactions on host and nonhost interactions in Puccinia triticina X poaceae
Leaf rust, caused by the fungus Puccinia triticina, is one of the major diseases of wheat. The environmental conditions present in the Southern Cone of South America, associated with a high genetic variability for virulence of the pathogen, favoring the occurrence of annual epidemics. Thus, it is common the overcome of resistance in varieties with specific r

23. Beta-glucosidase activity of soybean epicotyls in germination.
Isoflavones are compounds with benefits for human health and they are the mainly forms of glycosides in vegetables. ?-glucosidase (?-D-glucoside glucohydrolase, E.C.3.2.1.21) hydrolyses ?-D-glucosides releasing glucose and forming aglycone isoflavones. The aglycone isoflavone is the most bioavailable form of the glycosides. ?-glucosidase that converts glycos
