Genetic variability in banana diploids and nonparametric statistics of fragments associated with natural fruit finger drop

Natural fruit finger drop in bananas is one of the major concerns of producers as well as consumers. The aim of this study was to estimate the genetic diversity among 15 diploid bananas with different levels of resistance to finger drop (RFD) using SSR and ISSR (inter-simple sequence repeat) markers, and assess the possibility of association of bands with RFD variab..

Low-level trisomy 14 mosaicism in a male newborn with ectrodactyly

    M.A. Rodrigues, L.F. Morgade, L.F.A. Dias, R.V. Moreira, P.D. Maia, A.F.H. Sales and P.D. Ribeiro

Complete trisomy 14 mosaicism is a rare chromosome disorder and was first reported in 1970. We describe a case of a male neonate who presented complete trisomy 14 mosaicism in only 4% of the cells from peripheral blood. A nineteen-day-old male neonate was born as result of the second pregnancy. The infant was delivered by cesarean section due to gestational hyperten.. Read More»

Mapping of AFLP loci linked to tolerance to cowpea golden mosaic virus

    M.A. Rodrigues C.A.F. Santos J.R.F. Santana

AFLP markers combined with the bulk segregant analysis methodology was used for the identification of molecular markers associated with the cowpea golden mosaic virus (CGMV) resistance gene in 286 F2 cowpea plants derived from the cross IT97K-499-35 x Canapu T16. Segregation data in the F2 population demonstrated that tolerance to CGMV is controlled by a single dominant gene. Among the 196 combina.. Read More»

Down-Klinefelter syndrome (48,XXY,+21) in a neonate associated with congenital heart disease

Double aneuploidy is considered a rare phenomenon. Herein, we describe a case of double aneuploidy 48,XXY,+21 in a neonate with congenital heart defects. The 28-day-old neonate male (23-year-old mother and 24-year-old father) was admitted to a neonatal intensive care unit owing to congenital heart disease. Echocardiography showed a complete atrioventricular septal d.. Read More»
