Influence of sugars and hormones on the genes involved in sucrose metabolism in maize endosperms

Authors: X.D. Ren, H.M. Liu, Y.H. Liu, Y.F. Hu, J.J. Zhang and Y.B. Huang

Starch is the major storage product in the endosperm of cereals. Its synthesis is closely related to sucrose metabolism. In our previous study, we found that the expression of most of the genes involved in starch synthesis might be regulated by sugars and hormones in the maize endosperm. However, little is known regarding the transcriptional regulation of.. Read More»

Resistant starch: a functional food that prevents DNA damage and chemical carcinogenesis

Authors: S.D. Navarro, M.O. Mauro, J.R. Pesarini, F.M. Ogo and R.J. Oliveira

Resistant starch is formed from starch and its degradation products and is not digested or absorbed in the intestine; thus, it is characterized as a fiber. Because fiber intake is associated with the prevention of DNA damage and cancer, the potential antigenotoxic, antimutagenic, and anticarcinogenic capabilities of resistant starch from green banana flou..

Microsporogenesis in sexual Brachiaria hybrids (Poaceae)

Authors: V.A. Fuzinatto, M.S. Pagliarini and C.B. Valle

Three sexual interspecific hybrids of Brachiaria (HBGC076, HBGC009, and HBGC014) resulting from crosses between B. ruziziensis (female genitor) and B. decumbens and B. brizantha (male genitors) produced by Embrapa Beef Cattle in the 1980s were cytologically analyzed by conventional methods for meiotic studies. The cytogenetic .. Read More»

Lack of interpopulation genetic structure in the genus Stegastes (Perciformes) with indication of local introgression

Authors: E.A. Dias Jr., A.S. Souza and W.F. Molina

The family Pomacentridae comprises about 326 species belonging to 28 genera. The genus Stegastes is composed of nearly 33 species, and 8 are endemic to the Brazilian Province, inhabiting the Brazilian coast (Stegastes fuscus, S. variabilis, S. leucosticus, S. uenfi, and S. pictus) or Western Atlantic oceanic islands (S. trinda..

Genetic diversity of wild soybean populations in Dongying, China, by simple sequence repeat analysis

Authors: Y.H. Wang, X.J. Zhang and S.J. Fan

Annual wild soybean (Glycine soja Sieb. et Zucc.), the ancestor of cultivated soybean (G. max), is believed to be a potential gene source for further improvement of soybean to cope with environmental stress. In this study, 10 simple sequence repeat (SSR) markers were used to evaluate the genetic diversity and population genetic structure in five wild soyb.. Read More»

Evaluation of five protocols for DNA extraction from leaves of Malus sieversii, Vitis vinifera, and Armeniaca vulgaris

Authors: K. Aubakirova1,2, M. Omasheva1, N. Ryabushkina1, T. Tazhibaev2,G. Kampitova2 and N. Galiakparov1

Leaves of Malus sieversii, Vitis vinifera, and Armeniaca vulgaris contain substantial amounts of secondary metabolites, which limit the high-quality DNA extraction performance. In this study, five extraction protocols were compared for their ability to produce good quality DNA from fresh and dried (with silica gel) leaves of t.. Read More»

Evaluation of genetic similarity between accessions of Pityrocarpa moniliformis (angico-de-bezerro) using RAPD markers

Authors: F.M.S. Sousa, R.M. Mendes, R.F.M. Mendes, R.B. Araujo Neto, M.P.S.B.C. Nascimento and P.S.C. Lima

Pityrocarpa moniliformis (Benth.) Luckow and Jobson, commonly known as angico-de-bezerro, is a forage legume that occurs naturally in the Caatinga of northeastern Brazil. This fast growing, vigorous, melliferous tree is well adapted to arid terrains and its branches and leaves possess high nutritional value. However, the scarcity of information r.. Read More»

Authors: R.F.M. Mendes, R.B. Araujo Neto, M.P.S.B.C. Nascimento and P.S.C. Lima

Among members of the Fabaceae family, native to the Brazilian Caatinga, the species Poincianella pyramidalis and P. bracteosa exhibit particular potential as forage for cattle, sheep and goats. With the aim of establishing genetic relationships within Poincianella, random amplified polymorphic DNA analysis wa.. Read More»

Assessment of genetic diversity of bermudagrass germplasm from southwest China and Africa by using AFLP markers

Authors: Y. Ling, L.K. Huang, X.Q. Zhang, X. Ma, W. Liu, S.Y. Chen and H.D. Yan

Cynodon dactylon (L.) Pers. var. dactylon (common bermudagrass) is widely distributed geographically between approximately 45°N and 45°S latitude, penetrating to approximately 53°N latitude in Europe. The extensive variation of morphological and adaptive characteristics of the taxon has been substantially documented, but information is lacking.. Read More»
