Genetic dissimilarity of putative gamma-ray-induced �Preciosa - AAAB-Pome type� banana (Musa sp) mutants based on multivariate statistical analysis
Authors: R.K.N. Pestana, E.P. Amorim, C.F. Ferreira, V.B.O. Amorim, L.S. Oliveira, C.A.S. Ledo and S.O. Silva
Bananas are among the most important fruit crops worldwide, being cultivated in more than 120 countries, mainly by small-scale producers. However, short-stature high-yielding bananas presenting good agronomic characteristics are hard to find. Consequently, wind continues to damage a great number of plantations each year, leadi..

A glimpse of the endophytic bacterial diversity in roots of blackberry plants (Rubus fruticosus)
Authors: M. Contreras1, P.D. Loeza2, J. Villegas1, R. Farias1 and G. Santoyo1
The aim of this study was to explore the diversity of culturable bacterial communities residing in blackberry plants (Rubus fruticosus). Bacterial endophytes were isolated from plant roots, and their 16S rDNA sequences were amplified and sequenced. Our results show that the roots of R. fruticosus exhibit low colony forming units of bacterial endophytes pe.. Read More»

Cloning and sequence analysis of an actin gene in aloe
Authors: S.S. Wen, D.W. He, C.M. Liao, J. Li, G.Q. Wen, and X.H. Liu
Aloe (Aloe spp), containing abundant polysaccharides and numerous bioactive ingredients, has remarkable medical, ornamental, calleidic, and edible values. In the present study, the total RNA was extracted from aloe leaf tissue. The isolated high-quality RNA was further used to clone actin gene by using reverse transcr.. Read More»

Genome-wide identification, phylogeny and expression analysis of the lipoxygenase gene family in cucumber
Authors: S.Q. Liu, X.H. Liu and L.W. Jiang
Plant lipoxygenase (LOX) is involved in growth and developmental control processes, through the biosynthesis of regulatory molecules and defense responses to pathogens, wounding and stress. To date, few LOX proteins and little tissue expression profiling have been reported in detail for cucumber (Cucumis sativus L.). Recent co.. Read More»

Combining abilities for agronomic traits and marker-assisted selection for Potato virus X and Potato virus Y resistance
Authors: M.L. Guedes, C.A.B.P. Pinto, G.H.M.R. Ribeiro, D.H. Lyra and O.L.G. Carneiro
Disease-resistant potato cultivars with good tuber appearance and desirable agronomic traits are essential for meeting the demands of producers and the market. Attaining these cultivars is the focus of potato breeding programs whose aim is to benefit the productive chain. The purpose of this study was to estimate combining abilities and evaluate potato cl..

Functional characterization and signal transduction ability of nucleotide-binding site-leucine-rich repeat resistance genes in plants
Authors: R.K. Joshi and S. Nayak
Pathogen infection in plants is often limited by a multifaceted defense response triggered by resistance genes. The most prevalent class of resistance proteins includes those that contain a nucleotide-binding site-leucine-rich repeat (NBS-LRR) domain. Over the past 15 years, more than 50 novel NBS-LRR class resistance genes ha.. Read More»

Isolation and characterization of genetic variability in bacteria with �²-hemolytic and antifungal activity isolated from the rhizosphere of Medicago truncatula plants
Authors: J.E. Hern�¡ndez-Salmer�³n, C.M. Prieto-Barajas, E. Valencia-Cantero, G. Moreno-Hagelsieb and G. Santoyo
In the present study, we analyzed the frequency of hemolytic and antifungal activities in bacterial isolates from the rhizosphere of Medicago truncatula plants. Of the 2000 bacterial colonies, 96 showed β-hemolytic activities (frequency, 4.8 x 10-2). Hemolytic isolates were analyzed for their genetic diversity by.. Read More»

Selection index using the graphical area applied to sugarcane breeding
Authors: L.A. Silva, R.T. Resende, R.A.D.C. Ferreira, G.N. Silv, V. Kist, M.H.P. Barbosa, M. Nascimento and L.L. Bhering
This study aimed to develop a multivariate selection index based on the graphical area of a polygon formed by standardized values, also known as radar chart. This methodology may be used to assist selection of superior genotypes in sugarcane breeding programs. Seven technological traits in 37 sugarcane genotypes were evaluated. An area index (AI) was cons.. Read More»

Development of a transposon-based marker system for mutation breeding in sorghum (Sorghum bicolor L.)
Authors: S.B. Im, S.-J. Kwon, J. Ryu, S.W. Jeong, J.B. Kim, J.-W. Ahn, S.H. Kim, Y.D. Jo, H.-I. Choi and S.-Y. Kang
Under certain circumstances, transposable elements (TE) can create or reverse mutations and alter the genome size of a cell. Sorghum (Sorghum bicolor L.) is promising for plant transposon tagging due to its small genome size and its low content of repetitive DNA. We developed a marker system based on targeted region amplification polymorphisms (TE-TRAP) t.. Read More»
