Authors: A.C. Silva Júnior, V.Q. Carneiro, I.G. Santos, W.G Costa, R.D.S. Rosado, C.D. Cruz and P.C. Soares
The estimation of the genotypic replacement rate is aimed at evaluating the performance of breeding programs. Thus, the objective of this study was to evaluate the dynamics of the genetic improvement program of flooded rice, developed in Minas Gerais, during the period from 1993 to 2016. We evaluated 210 lines in three environments between 1993 and 2016, .. Read More»

Digital image analysis to quantify genetic divergence in passion fruit seeds
Authors: Leandro Rafael Fachi, Willian Krause, Henrique Duarte Vieira, Dejânia Vieira de Araújo, Petterson Baptista da Luz, Alexandre Pio Viana
Phenotyping through digital images has been used to evaluate morphological characteristics of seeds, providing fast, accurate results. The objective of this work was to estimate the genetic divergence among full-sibling families of passion fruit through morphophysiological characteristics of seeds using the Ward-MLM method. Seeds of 98 full-sibling famili.. Read More»

AtBTH1, a BTB domain-containing protein, influences sugar-responsive germination and seedling growth in Arabidopsis
Authors: J.E. Hwang, Y.J. Kim, M.H. Shin, J. Park, W. Choi, D.J. Yun and H.C. Park
Sugars function as signal molecules that regulate gene expression, growth, and development in plants, animals, and yeasts. As a contribution to understanding the molecular mechanisms of sugar responses, we identified and characterized an Arabidopsis thaliana BTB domain-containing protein of the H subfamily 1 (designated AtBTH1). The relative expression le.. Read More»

Genetic variability in morphological characters among Fig tree accessions Fig genetic conservation
Authors: Maria Gabriela Fontanetti Rodrigues*, Laís Naiara Honorato Monteiro, Antonio Flávio Arruda Ferreira, Tatiane Paes Dos Santos, Bruno Ettore Pavan, Vitos Antônio Benites Neves, Aparecida Conceição Boliani
Fig is among the twenty main fruits exported by Brazil, which is the eighth largest producer of fig in natura in the world. The characterization of active germplasm banks (AGBs) of fig has thus become an important line of research, as it is necessary to gather information from this to carry out adequate management projects. The objective of this study was.. Read More»

Analysis of the molecular diversity of R. solani isolates from five Ugandan agro-ecological zones using inter - simple sequence repeat markers
Authors: A.S. Male , F. Kato, P. Paparu and C.M. Mukankusi
This study used seven inter-simple sequence repeat (ISSR) markers to characterize 55 R. solani isolates in order to establish their genetic diversity. The isolates were from five common bean growing agro-ecological zones of Uganda; the Southwest highlands (SW), Lake Victoria crescent and Mbale farmlands (LVC), Teso farming system (TFS), the Northern mixed..

Genetic damage in Mexican and South American sweet corn varieties due to the use of herbicides (Nicosulfuron and Topramezone)
Authors: M.S. Reynoso, C.M. Alvarez, L.L. De la Cruz, J.F.G. Landeros, J.J.G. Sánchez, A.R.A. Villalobos
In order to encourage corn production, several herbicides such as nicosulfuron and topramezone are used. Though they offer great advantages, they may affect crop productivity and may even induce DNA damage. This study evaluated genotoxic activity at two nicosulfuron concentrations (40,000 and 80, 000 ppm) and at four topramezone concentrations (1480, 148,.. Read More»

Genetic diversity and population structure of ancient Platycladus orientalis (Cupressaceae) in the Mausoleum of the Yellow Emperor revealed by SSR
Authors: Yao Xu1, Jiantao Zhao, Sheng Zhang, Zhong Zhao
Ancient trees can serve as genetic reservoirs for special genes, and they are of significance in genetic applications dealing with forest fragmentation, climate change and drought. The Mausoleum of the Yellow Emperor in Shaanxi China has the largest number of ancient Platycladus orientalis trees. Here, Simple sequence repeat (SSR) technique was used to st.. Read More»

DNA Extraction from silica gel preserved common bean (Phaseolus vulgaris L.) leaves
Authors: Male. A.S, Kato. F, Mukankusi. C.M
Extraction of high-quality DNA from field specimen requires collection under liquid nitrogen which is not readily available in resource constrained laboratories in low- and middle-income countries (LMICs). A method of extracting DNA from silica gel preserved common bean (Phaseolus vulgaris L.) leaves is presented. Our method which does not involve the use.. Read More»
