Authors: M. Yang, S.G. Shi, W. Liu, M. Zhang, L. Gou, Y.X. Kang and J.J. Liu
The population of Magnolia sprengeri individuals deceased drastically in the late 20th century because of the widespread harvest for traditional Chinese medicinal recipes. In this study, the levels of phenotypic variation and the genetic structure of 2 populations of M. sprengeri were estimated. The phenotypic variation of M. sprengeri characteristics was.. Read More»

Molecular characterization of the myosatin gene and the effect of fasting on its expression in Chinese perch (Siniperca chuatsi)
Authors: L. Liu, Y.L. Li, S.D. Xu, K.Z. Wang, P. Wu, W.Y. Chu and X.Q. Wang
Myostatin (MSTN) is an important member of the transforming growth factor-β (TGF-β) superfamily and is a muscle growth inhibitor. In the present study, we cloned the Chinese perch MSTN cDNA sequence and analyzed its expression patterns under various conditions. The MSTN full cDNA sequence was 3347 bp long, including ..

Fine mapping and characterization of the or gene in Chinese cabbage (Brassica rapa L. ssp pekinensis)
Authors: C.L. Zou, Y. Zheng, P. Wang, X. Zhang, Y.-H. Wang, Z.Y. Liu and H. Feng
Orange inner leaves/heads is a qualitative trait in Chinese cabbage that is controlled by a single recessive gene. Orange head Chinese cabbage contain more carotenoids than its white head counterpart; hence, this trait is of interest to both researchers and consumers. In this study, we selected the orange head Chinese cabbage .. Read More»

TcCYS4, a cystatin from cocoa, reduces necrosis triggered by MpNEP2 in tobacco plants
Authors: L.S. Santana, M.G.C. Costa, N.M. Pirovani, A.F. Almeida, F.C. Alvim and C.P. Pirovani
In Brazil, most cocoa bean production occurs in Southern Bahia. Witches’ broom disease arrived in this area in 1989 and has since caused heavy losses in production. The disease is caused by the basidiomycete fungus Moniliophthora perniciosa, a hemibiotrophic fungus that produces the necrosis and ethylene-inducti.. Read More»

Identification of grapevine rootstock cultivars using expressed sequence tag-simple sequence repeats
Authors: X.C. Fan, J.Q. Chu, C.H. Liu, X. Sun and J.G. Fang
Grapevine (Vitis) rootstock varieties or cultivars are used to confer resistance and tolerance to insect and disease pests, unfavorable soil conditions, and other environmental conditions to cultivars that are susceptible to these conditions but otherwise have desired properties. The need to genotype and thoroughly id.. Read More»

Screening of inbred popcorn lines for tolerance to low phosphorus
Authors: O.J.A.P. Santos, L.S.A. Gon�§alves, C.A. Scapim, de S.M. de Sousa, C.R. Castro, V. Y. Baba and A.L.M. de Oliveira
Increasing phosphorus use efficiency in agriculture is essential for sustainable food production. Thus, the aims of this study were: i) to identify phosphorus use efficiency (PUE) in popcorn lines during the early plant stages, ii) to study the relationship between traits correlated with PUE, and iii) to analyze genetic divers..

Characterization and genetic diversity of pepper (Capsicum spp) parents and interspecific hybrids
Authors: M.P.S.D. Costa, M.M. do R�ªgo, A.P.G. da Silva, E.R. do R�ªgo and P.A. Barroso
Pepper species exhibit broad genetic diversity, which enables their use in breeding programs. The objective of this study was to characterize the diversity between the parents of different species and their interspecific hybrids using morphological and molecular markers. The parents of Capsicum annuum (UFPB-01 and -137), C. ba.. Read More»

Variation in cassava germplasm for tolerance to post-harvest physiological deterioration
Authors: M.T. Venturini, L.R. Santos, C.I.A. Vildoso, V.S. Santos and E.J. Oliveira
Tolerant varieties can effectively control post-harvest physiological deterioration (PPD) of cassava, although knowledge on the genetic variability and inheritance of this trait is needed. The objective of this study was to estimate genetic parameters and identify sources of tolerance to PPD and their stability in cassava acce.. Read More»

Authors: Z.B. Li1, G. Dai1, J.B. Shangguan, Y.F. Ning,Y.Y. Li, R.B. Chen, Y.S. Huang andY. Yuan
The sea cucumber Holothuria scabra is an endangered species. In this study, nine new polymorphic microsatellite loci were developed and tested in 30 individuals. The number of alleles ranged from 2 to 5, and the observed and expected heterozygosities ranged from 0.1200 to 0.7391 and from 0.2408 to 0.5983, respectively. No loci significantly deviated from ..
