Contributions of classical and molecular cytogenetic in meiotic analysis and pollen viability for plant breeding
Authors: M.P. Lavinscky, M.M. Souza, G.S. Silva and C.A.F. Melo
The analysis of meiotic behavior has been widely used in the study of plants as they provide relevant information about the viability of a species. Meiosis boasts a host of highly conserved events and changes in genes that control these events will give rise to irregularities that can alter the normal course of meiosis and may.. Read More»

Tissue distribution and early developmental expression patterns of aldolase A, B, and C in grass carp Ctenopharyngodon idellus
Authors: J.J. Fan, J.J. Bai, D.M. Ma, L.Y. Yu and P. Jiang
Aldolase is a key enzyme involved in glycolysis, gluconeogenesis, and the pentose phosphate pathway. To establish the expression patterns of all three aldolase isozyme genes in different tissues and during early embryogenesis in lower vertebrates, as well as to explore the functional differences between these three isozymes, t..

Genetic control of number of flowers and pod set in common bean
Authors: E.S. Martins, R.A. Pinto J�ºnior, A.F.B. Abreu and M.A.P. Ramalho
This article aimed to study the genetic control of some flowers and pod set of common bean and to verify if its estimate varies with environmental conditions and gene pool. A complete diallel was used among six lines, but no reciprocal ones. The treatments were evaluated in three harvests/generations - F2, F3, and F4 - in 2015.. Read More»

In silico modeling and characterization of phytoparasitic nematodes translationally-controlled tumor proteins
Authors: R.M. Moraes Filho, A.F. Menezes and L.S.S. Martins
Plant parasitic nematodes infect a wide range of hosts representing the largest source of biotic stress experienced by plants. Meloidogyne genus comprises the most important parasitic nematodes, also known as root-knot nematodes. These parasitic organisms obtain nutrients to support their development through complex interactio.. Read More»

Improving the PCR protocol to amplify a repetitive DNA sequence
Authors: J. Riet, L.R.V. Ramos, R.V. Lewis and L.F. Marins
Although PCR-based techniques have become an essential tool in the field of molecular and genetic research, the amplification of repetitive DNA sequences is limited. This is due to the truncated nature of the amplified sequences, which are also prone to errors during DNA polymerase-based amplification. The complex structure of repetitive DNA can form hair..

Genetic diversity among 16 genotypes of Coffea arabica in the Brazilian cerrado
Authors: C.M.S. Machado, N.S. Pimentel, A. Golynsk, A. Ferreira, H.D. Vieira and F.L. Partelli
For the selection of coffee plants that have favorable characteristics, it is necessary to evaluate variables related to production. Knowledge of the genetic divergence of arabica coffee is of extreme importance, as this knowledge can be associated with plant breeding programs in order to combine genetic divergence with good p..

Genetic diversity of high performance cultivars of upland and irrigated Brazilian rice.
Authors: G.R.C. Coelho, C. Brondani, L.V. Hoffmann, P.A.M.R. Valdisser, T.C.O. Borba, J.A. Mendon�§a, L.A. Rodrigues and I.P.P. de Menezes
The objective of this study was to analyze the diversity and discrimination of high-performance Brazilian rice cultivars using microsatellite markers. Twenty-nine rice cultivars belonging to EMBRAPA Arroz e Feijão germplasm bank in Brazil were genotyped by 24 SSR markers to establish their structure and genetic discrimi.. Read More»

Periclinal chimera technique: new plant breeding approach
Authors: P.M. Gakpetor, H. Mohammed, D. Moreti and N.M.A. Nassar
Plant interspecific periclinal chimeras are a mosaic formed by tissues from two species. They are manipulated here as an efficient plant breeding tool for cassava root yields. In this study, plants synthesized from two chimeras, designated as chimera 2 and chimera 4, were characterized morphologically and cytologically to unra.. Read More»
