Distribution of mating-type alleles and M13 PCR markers in the black leaf spot fungus Mycosphaerella fijiensis of bananas in Brazil
Authors: C.B. Queiroz E.C. Miranda R.E. Hanada N.R. Sousa L. Gasparotto M.A. Soares G.F. Silva
The fungus Mycosphaerella fijiensis is the causative agent of black sigatoka, which is one of the most destructive diseases of banana plants. Infection with this pathogen results in underdeveloped fruit, with no commercial value. We analyzed the distribution of the M. fijiensis mating-type system and its genetic variability using M13 phage DNA markers. We fo.. Read More»

Physiological evaluation of the responses of Larix olgensis families to drought stress and proteomic analysis of the superior family
Authors: L. Zhang, H.G. Zhang, Q.Y. Pang
The conifer Larix olgensis has been analyzed to delineate physiological and proteomic changes that occur under drought stress. Studies of the deleterious effects of drought in the larch families have mainly focused on photosynthesis. In the present study, when the intensity of drought was increased, plant height was inhibited .. Read More»

Chromosomal diversity in Hypostomus (Siluriformes, Loricariidae) with emphasis on physical mapping of 18S and 5S rDNA sites
Authors: J.B. Traldi D.R. Blanco M.R. Vicari J.F. Martinez R.L. Lui A.V. Barros R.F. Artoni O. Moreira-Filho
We examined chromosomes of three species of the genus Hypostomus, in order to contribute to the understanding of the karyotype evolution of this group. Specimens of H. ancistroides and H. nigromaculatus displayed differences in karyotype formulas, distribution and location of heterochromatin and nucleolus organizer regions when compared to other populations ..

Analysis of the cytochrome c oxidase subunit II (COX2) gene in giant panda, Ailuropoda melanoleuca
Authors: S.S. Ling, Y. Zhu, D. Lan, D.S. Li, H.Z. Pang, Y. Wang, D.Y. Li, R.P. Wei, H.M. Zhang, C.D. Wang and Y.D. Hu
The giant panda, Ailuropoda melanoleuca (Ursidae), has a unique bamboo-based diet; however, this low-energy intake has been sufficient to maintain the metabolic processes of this species since the fourth ice age. As mitochondria are the main sites for energy metabolism in animals, the protein-coding genes involved in mitochond.. Read More»

Identification of resistance gene analogs in Korean wild apple germplasm collections
Authors: D.E. Baek C. Choi
Several plant disease resistance gene (R-gene) classes have been identified on the basis of specific conserved functional domains. Cloning of disease-resistance apple genes would be useful for breeding programs and for studying resistance mechanisms. We used a PCR approach with degenerate primers designed from conserved NBS-LRR (nucleotide binding site-le.. Read More»

Guaçatonga (Casearia sylvestris) is a native plant of the Atlantic Forest, with high medicinal potential and relevance for reforestation programs. The aim of this study was to characterize, with microsatellite markers, two populations of C. sylvestris from remaining areas of the Atlantic Forest in the State of Sã.. Read More»

Genetic diversity of Cajazeira (Spondias mombin L.) in three geographic regions
Authors: B.M. Silva, A.A.B. Rossi, A.V. Tiago, K.F.M. Schmitt, J.F.E. Dardengo and S.A.M. Souza
Cajazeira (Spondias mombin L.), of the family Anacardiaceae, is a species of fruit tree found in the Amazon region with fruits that have excellent prospects for commercial use. We aimed to evaluate the genetic diversity within and among natural populations of S. mombin, with natural occurrence in northern Mato Grosso State, by.. Read More»

Phenotypic and molecular characterization of a tomato (Solanum lycopersicum L.) F2 population segregation for improving shelf life
Authors: K.N. Yogendra P.H. Ramanjini Gowda
Breeding for better quality fruits is a major focus for tomatoes, which are continuously subjected to post-harvest losses. Several methods have been used to improve the fruit shelf life of tomatoes, including the use of ripening gene mutants of Solanum lycopersicum. We developed extended shelf-life tomato hybrids with better quality fruits using ripening .. Read More»

Antisense expression of Gossypium hirsutum UDP-glucuronate decarboxylase in Arabidopsis leads to changes in cell wall components
Authors: D.M. Zhang1*, Y.X. Pan2*, Y. Zhang1, Z.K. Li1, L.Q. Wu1, H.W. Liu1, G.Y. Zhang1, X.F. Wang1 and Z.Y. Ma1
UDP-glucuronate decarboxylase (UDP-xylose synthase; UXS, EC 4.1.1.35) is an essential enzyme of the non-cellulosic polysaccharide biosynthetic pathway. In the present study, using transient expression of fluorescently labeled Gossypium hirsutum UXS (GhUXS3) protein in onion epidermal cells, we observed that this protein was distributed in the cytoplasm. T.. Read More»

Association of the GSTT1 polymorphism in upper aerodigestive tract cancer with tobacco smoking
Authors: T.M. Silva, C.R. Marques, M.F. Marques Filho, A.B. Marques, G. Di Pietro and F. Rios-Santos
Polymorphisms in genes encoding xenobiotic-metaboli- zing enzymes might explain differences in the susceptibility to upper aerodigestive tract (UADT) cancers in individuals exposed to tobacco or other carcinogens. The present study aimed to evaluate the association of polymorphisms in the glutathione S-transferase (GST) candid.. Read More»
