Authors: I.P.P. de Menezes1, J.O. da Silva1, G. Malafaia1, R.D.D. Silveira1 andP.A.V. Barroso2
Cotton has been collected in Brazil for decades for its conservation, evaluation, and the use of its genetic resources. Gossypium mustelinum is an allotetraploid cotton species that only occurs in Brazil, and little is known about its genetic potential for improvement. However, the species is threatened by habitat fragmentation and interspecific hybridiza.. Read More»

Factor analysis using mixed models of multi-environment trials with different levels of unbalancing
Authors: J.J. Nuvunga1, L.A. Oliveira2, A.K.A. Pamplona1, C.P. Silva1, R.R. Lima1 andM. Balestre1
This study aimed to analyze the robustness of mixed models for the study of genotype-environment interactions (G x E). Simulated unbalancing of real data was used to determine if the method could predict missing genotypes and select stable genotypes. Data from multi-environment trials containing 55 maize hybrids, collected during the 2005-2006 harvest sea.. Read More»

Detection of quantitative trait loci for ear row number in F2 populations of maize
Authors: C. Yang1,2, J. Liu1,2 and T.Z. Rong1,2
Ear row number (ERN) is not only a key trait involved in maize (Zea mays L.) evolution but is also an important component that is directly related to grain yield. In this study, quantitative trait loci (QTLs) for ERN were detected across two F2 populations that were derived from a same cross between B73 with 16 rows (N = 233) and SICAU1212 with four rows ..

Construction of a cDNA library and preliminary analysis of expressed sequence tags in Piper hainanense
Authors: R. Fan, P. Ling, C.Y. Hao, F.P. Li, L.F. Huang, B.D. Wu and H.S. Wu
Black pepper is a perennial climbing vine. It is widely cultivated because its berries can be utilized not only as a spice in food but also for medicinal use. This study aimed to construct a standardized, high-quality cDNA library to facilitated identification of new Piper hainanense transcripts. For this, 262 unigenes were us.. Read More»

Analysis of the genetic diversity of Chinese native Cannabis sativa cultivars by using ISSR and chromosome markers
Authors: L.G. Zhang, Y. Chang, X.F. Zhang, F.Z. Guan, H.M. Yuan, Y. Yu and L.J. Zhao
Hemp (Cannabis sativa) is an important fiber crop, and native cultivars exist widely throughout China. In the present study, we analyzed the genetic diversity of 27 important Chinese native hemp cultivars, by using inter-simple sequence repeats (ISSR) and chromosome markers. We determined the following chromosome formulas: 2n = 20 = 14m + 6sm; 2n = 20 = 2.. Read More»

Protein extraction method for the proteomic study of Zymomonas mobilis during production of ethanol and levans
Authors: D.R. Cavalcanti, C.B. Malafaia, T.D. Silva, B.S. Santos,G.M.T. Calazans and M.V. Silva
Zymomonas mobilis has aroused considerable interest owing to its rapid metabolism and efficiency in producing ethanol and by-products such as levans, sorbitol, and gluconic acid from simple sugars. We performed a proteomic analysis of Z. mobilis UFPEDA241 to provide a global profile of regulatory proteins. The choice of the methods of extraction and cell .. Read More»

Evaluation of grain yield in sorghum hybrids under water stress
Authors: C.B. Menezes, D.C. Saldanha, C.V. Santos, L.C. Andrade, M.P. Mingote J�ºlio, A.F. Portugal and F.D. Tardin
Sorghum grain yield can be significantly affected by climatic changes, especially drought and high temperature. The purpose of this study was to evaluate hybrids of grain sorghum grown under normal irrigation conditions or water stress in order to select those likely to be more tolerant of drought. Forty-nine hybrids were grow.. Read More»

Induction and identification of Stylosanthes guianensis tetraploids
Authors: F.H. Wu, X.D. Yu, N.S. Zhuang, G.D. Liu and J.P. Liu
Stylosanthes guianensis is an elite and important forage legume species, which is extensively cultivated in tropical areas. Polyploid breeding via exposure to colchicine is a conventional and practical method to improve varieties of S. guianensis. Terminal buds of S. guianensis Reyan No.5 seedlings were treated with different .. Read More»

Assessing the genotoxicities of sparteine and compounds isolated from Lupinus mexicanus and L. montanus seeds by using comet assay
Authors: M.R. Silva, C.M. Alvarez, P.M. GarcÃ?Âa and M.A. Ruiz
The genus Lupinus is widely distributed. Its seeds are used for animal and human food, and Lupinus possesses pharmacological potential because of its high content of quinolizidine alkaloids and flavonoids; however, there is little available information about its genotoxicity. We used the comet assay and staminal nuclei of Tradescantia (clone 4430) to eval.. Read More»
