Development of CAPS markers to identify Indian tea (Camellia sinensis) clones with high catechin content
Authors: M. Elangbam and A.K. Misra
Tea leaves are rich in plant secondary phenolics, especially flavonoids. Catechins are considered to be the most valuable flavonoids, and the catechin content in tea is an important trait for determining its quality. We have developed cleaved amplified polymorphic sequence (CAPS)-based markers for evaluating total catechin con.. Read More»

Genetic diversity and structure of native and non-native populations of the endangered plant Pinus dabeshanensis
Authors: Z.Y. Zhang, H. Wang, W. Chen, X.M. Pang and Y.Y. Li
Owing to a severe decline in its abundance, Pinus dabeshanensis has been listed as an endangered species by the International Union for the Conservation of Nature. Although several restoration events have been undertaken since the 1960s, the natural population genetic structure of this species remains to be investigated. Herei.. Read More»

Genetic diversity and structure of the threatened species Sinopodophyllum hexandrum (Royle) Ying
Authors: W. Liu, J. Wang, D.X. Yin, M. Yang, P. Wang, Q.S. Han, Q.Q. Ma, J.J. Liu and J.X. Wang
Sinopodophyllum hexandrum is an important medicinal plant that has been listed as an endangered species, making the conservation of its genetic diversity a priority. Therefore, the genetic diversity and population structure of S. hexandrum was investigated through inter-simple sequence repeat analysis of eight natural populati.. Read More»

Genetic and epigenetic alterations induced by different levels of rye genome integration in wheat recipient
Authors: X.L. Zheng, J.P. Zhou, L.L. Zang, A.T. Tang, D.Q. Liu, K.J. Deng and Y. Zhang
The narrow genetic variation present in common wheat (Triticum aestivum) varieties has greatly restricted the improvement of crop yield in modern breeding systems. Alien addition lines have proven to be an effective means to broaden the genetic diversity of common wheat. Wheat-rye addition lines, which are the direct bridge ma.. Read More»

A comparative framework of the Erythrina velutina tree species in reforested land and native populations
Authors: E.M.S. Souza, G.S. Pereira, R. Silva-Mann, S.V. ?lvares-Carvalho and R.A. Ferreira
Erythrina velutina Willd. (Fabaceae: Papillionoideae) is a pioneer species found in tropical and subtropical regions of the world that has medicinal properties and that is used in reforestation projects. This species is rare in some areas of northeastern Brazil. This study aimed to characterize and compare genetic structures o.. Read More»

Bayesian GGE biplot models applied to maize multi-environments trials
Authors: L.A. de Oliveira, C.P. da Silva, J.J. Nuvunga, A.Q. da Silva and M. Balestre
The additive main effects and multiplicative interaction (AMMI) and the genotype main effects and genotype x environment interaction (GGE) models stand out among the linear-bilinear models used in genotype x environment interaction studies. Despite the advantages of their use to describe genotype x environment (AMMI) or genoty.. Read More»

Antiviral RNA silencing suppression activity of Tomato spotted wilt virus NSs protein
Authors: T. Ocampo Ocampo, S.M. Gabriel Peralta, N. Bacheller, S. Uiterwaal, A. Knapp, A. Hennen, D.L. Ochoa-Martinez and H. Garcia-Ruiz
In addition to regulating gene expression, RNA silencing is an essential antiviral defense system in plants. Triggered by double-stranded RNA, silencing results in degradation or translational repression of target transcripts. Viruses are inducers and targets of RNA silencing. To condition susceptibility, most plant viruses en.. Read More»

Flow cytometry reliability analysis and variations in sugarcane DNA content
Authors: A.C.L. Oliveira, M. Pasqual, A.T. Bruzi, L.A.S. Pio, P.M.S. Mendon?§a and J.D.R. Soares
The aim of this study was to evaluate the reliability of flow cytometry analysis and the use of this technique to differentiate species and varieties of sugarcane (Saccharum spp) according to their relative DNA content. We analyzed 16 varieties and three species belonging to this genus. To determine a reliable protocol, we evaluated three extraction buffe.. Read More»

Drought is one of the most frequent abiotic stresses limiting the productivity and geographical distribution of sugarcane culture. The use of drought-tolerant genotypes is one approach for overcoming the effects of water stress. We conducted a comparative study to identify gene expression profiles under water stress in tolerant sugarcane roots. Two differ.. Read More»
