QTLs for rice flag leaf traits in doubled haploid populations in different environments
Authors: J. Cai, M. Zhang, L.B. Guo, X.M. Li, J.S. Bao and L.Y. Ma
Two rice doubled haploid (DH) populations derived from the crosses of ZYQ8/JX17 and CJ06/TN1 were used to detect quantitative trait loci (QTLs) for flag leaf length (FLL), width (FLW), and angle (FLA) under long-day conditions in Hangzhou (subtropical zone) and short-day conditions in Hainan (tropical zone), China. The four parents differed significantly .. Read More»

Artificial neural networks reveal efficiency in genetic value prediction
Authors: L.A. Peixoto, L.L. Bhering and C.D. Cruz
The objective of this study was to evaluate the efficiency of artificial neural networks (ANNs) for predicting genetic value in experiments carried out in randomized blocks. Sixteen scenarios were simulated with different values of heritability (10, 20, 30, and 40%), coefficient of variation (5 and 10%), and the number of genotypes per block (150 and 200 .. Read More»

Identification of smut-responsive genes in sugarcane using cDNA-SRAP
Authors: N. Huang, Y.Y. Zhang, X.H. Xiao, L. Huang, Q.B. Wu, Y.X. Que and L.P. Xu
Sugarcane smut, caused by the fungus Sporisorium scitamineum, is one of the main diseases that affect sugarcane worldwide. In the present study, the cDNA-SRAP technique was used to identify genes that are likely to be involved in the response of sugarcane to S. scitamineum infection. In total, 21 bands with significant differential expression during cDNA-.. Read More»

MicroRNA analysis in model species based on evolutionary rates
Authors: X.F. Mao and Y.C. Cao
MicroRNAs (miRNAs) are major post-transcriptional regulators of gene expression. In an attempt to gain insights into miRNAs at the macroevolutionary level, we performed a systematic analysis of miRNAs in six model organisms based on their evolutionary rates. First, we calculated their miRNA evolutionary rates, and found that they did not correlate with th.. Read More»

Novel splice variants of the bovine PCK1 gene
Authors: Z.B. Zhang, W. Zhang, R.L. Li, J.B. Li, J.F. Zhong, Z.S. Zhao and J.M. Huang
Phosphoenolpyruvate carboxykinase 1 (PCK1), also named PEPCK-C, is a multiple-function gene that is involved in gluconeogenesis, glyceroneogenesis, reproduction, female fertility, and development of obesity and diabetes. How its many functions are regulated was largely unknown. Therefore, we investigated mRNA expression and possible splice variants of PCK.. Read More»

Cloning and expression of an APETALA1-like gene from Nelumbo nucifera
Authors: D.Z. Kong, X.Y. Shen, B. Guo, J.X. Dong, Y.H. Li and Y.P. Liu
The objective of this study was to clone the full-length cDNA of the APETALA1 (AP1) gene from lotus and analyze its sequence and expression pattern. The full-length cDNA sequence of the NnAP1 gene was amplified from the petals of Nelumbo nucifera ‘Hongxia’ using RT-PCR and rapid amplification of cDNA ends. Bioinformatic methods were used to an..

Morphological and molecular characteristics do not confirm popular classification of the Brazil nut tree in Acre, Brazil
Authors: P.S. Sujii, E.T.M.B. Fernandes, V.C.R. Azevedo, A.Y. Ciampi, K. Martins and L.H. de O. Wadt
In the State of Acre, the Brazil nut tree, Bertholletia excelsa (Lecythidaceae), is classified by the local population into two types according to morphological characteristics, including color and quality of wood, shape of the trunk and crown, and fruit production. We examined the reliability of this classification by comparing morphological and molecula.. Read More»

STAT1 inhibitor alleviates spinal cord injury by decreasing apoptosis
Authors: Y.X. Wu, C.Z. Gao, K.L. Fan, L.M. Yang and X.F. Mei
Spinal cord injury (SCI) is typically caused by trauma or disease, and it severely affects patients’ motor function. The relationship between signal transducers and activators of transcription-1 (STAT1) and neuronal death after cerebral focal ischemia has been comprehensively studied, but its role in SCI remains largely ..

Development of microsatellite markers for a hard-shelled mussel, Mytilus coruscus, and cross-species transfer
Authors: J.H. Kang, Y.K. Kim, J.Y. Park, E.S. Noh, J.E. Jeong, Y.S. Lee and T.J. Choi
The Korean mussel Mytilus coruscus, an endemic marine bivalve mollusk, is economically important. Its population is currently decreasing due to overexploitation and invasion of a more competitive species, Mytilus galloprovincialis. In this study, microsatellite markers for M. coruscus were developed using a cost-effective pyrosequencing technique. Among t.. Read More»
