Evaluation of the genotoxic activity of dicamba and atrazine herbicides in several Mexican and South American varieties of sweetcorn (Zea mays L.)
Authors: M.S. Reynoso, C.M. Alvarez, L. De la Cruz, M.D. Escoto and J.J.G. S�¡nchez
Corn is a major crop and various herbicides are used to maximize its production, which include a dicamba-atrazine mixture. This has great advantages, but can also induce DNA damage. Genotoxic activity was assessed by comet assay following application of two concentrations of dicamba-atrazine: 1000-2000 and 2000-4000 ppm. Apical meristem leaf nuclei from 1.. Read More»

Adaptability and stability of conilon coffee in areas of high altitude
Authors: D.H.G.S. Barbosa, W.P. Rodrigues, H.D. Vieira, F.L. Partelli and A.P. Viana
In view of the predicted models of global climate change and differences in prices and production costs, there is increased interest in Coffea canephora cultivation in areas of high altitude. However, this species is sensitive to low temperatures, where genotypes vary regarding adaptation/tolerance mechanisms, demonstrating ge.. Read More»

New hybrids from peanut (Arachis hypogaea L.) and synthetic amphidiploid crosses show promise in increasing pest and disease tolerance
Authors: A.P. F�¡vero, J.G. P�¡dua, T.S. Costa, M.A. Gimenes, I.J. Godoy, M.C. Moretzsohn and M.D. Michelotto
The primary gene pool of the cultivated peanut (Arachis hypogaea L., allotetraploid AABB) is very narrow for some important characteristics, such as resistance to pests and diseases. However, the Arachis wild diploid species, particularly those from the section Arachis, still have these characteristics. To improve peanut crops, genes from the wild species.. Read More»

Molecular cloning and analysis of a receptor-like promoter of Gbvdr3 gene in sea island cotton
Authors: B.-J. Zhang, H.-P. Zhang, Q.-Z. Chen, N. Tang, L.-K. Wang, R.-F. Wang and B.-L. Zhang
Verticillium wilt caused by soil borne fungus Verticillium dahliae could significantly reduce cotton yield. The Ve1 homologous gene Gbvdr3 is resistant to Verticillium wilt. In order to understand of the function of the promoter Gbvdr3 in Gossypium barbadense, the promoter region of the receptor-like gene Gbvdr3 was obtained b.. Read More»

SSR-based association mapping of salt tolerance in cotton (Gossypium hirsutum L.)
Authors: Y.L. Zhao, H.M. Wang, B.X. Shao, W. Chen, Z.J. Guo, H.Y. Gong,X.H. Sang, J.J. Wang and W.W. Ye
The identification of simple sequence repeat (SSR) markers associated with salt tolerance in cotton contributes to molecular assisted selection (MAS), which can improve the efficiency of traditional breeding. In this study, 134 samples of upland cotton cultivars were selected. The seedling emergence rates were tested under 0.3.. Read More»

Detection and characterization of carbendazim resistance in Sclerotinia sclerotiorum isolates from oilseed rape in Anhui Province of China
Authors: D. Xu, Y. Pan, H. Zhang, X. Li, Y. Dai, S. Cao and Z. Gao
Stem rot caused by Sclerotinia sclerotiorum is a devastating disease of oilseed rape (Brassica napus) in Anhui Province of China. The fungicide carbendazim (methyl benzimidazole-2-yl carbamate; MBC) has been used to control this fungal disease since the 1980s. In the present study, 74 isolates of S. sclerotiorum from 13 regions of Anhui were collected, an.. Read More»

Comparative analysis of MIR168 promoters in three plant species
Authors: D. Qu, F. Yan M.A. Li, C. Varotto and Z.Y. Zhao
MicroRNAs (miRNAs) play important roles in the regulation of gene expression by post-transcriptionally targeting mRNAs for cleavage or translational repression. miR168 is a key miRNA because it regulates the expression of the slicer protein ARGONAUTE1 (AGO1), which catalyzes mRNA cleavage. Interestingly, plant miR168s are high.. Read More»

Selection in sugarcane based on inbreeding depression
Authors: A.A.C. de Azeredo, L.L. Bhering, B.P. Brasileiro, C.D. Cruz and M.H.P. Barbosa
This study aimed to evaluate the gene action associated with yield-related traits, including mean stalk weight (MSW), tons of sugarcane per hectare (TCH), and fiber content (FIB) in sugarcane. Moreover, the viability of individual reciprocal recurrent selection (RRSI-S1) was verified, and the effect of inbreeding depression on.. Read More»

Isolation and characterization of Calcineurin B-like gene (PbCBL1) and its promoter in birch-leaf pear (Pyrus betulifolia Bunge)
Authors: Y.Y. Xu, H. Li, J. Lin, X.G. Li and Y.H. Chang
Calcium plays a critical role in regulating abiotic stress responses in plants. Calcineurin B-like (CBL) proteins are calcium sensors in calcium signaling pathways. However, the molecular mechanisms underlying calcium signaling remain to be elucidated. In this study, the CBL1 gene, which codes for the CBL protein, was isolated from the birch-leaf pear. On..
