ABSTRACT - The objective of this work was to identify the quantitative trait loci (QTLs) associated with grain yield in a rice segregant population (GYP). A population of 245 inbred recombinant rice lines from the 'Epagri 108' (Oryza sativa subsp. indica) x 'IRAT 122' (O. sativa subsp. japonica) cross was
evaluated at different locations and years and genotyped by single nucletide polymorphism (SNP) markers. A map of 1,592.8 cM was obtained from
9,831 SNPs, identifying 25 QTLs. The following nine SNPs showed stability between the different environments: M1.37719614 and M6.9563117 for GYP;
M4.29340056, M5.25588710, M7.29115624, and M12.4534450 for 100-grain weight (HGW); and M1.38398157, M4.28368337, and M7.25991230 for plant height (PH). Six SNPs were not present in the linkage blocks: M6.9563117 and M4.1077080 for GYP; M5.25588710 and M6.8886398 for HGW; and
M2.34471005 and M8.5955948 for PH. The M6.9563117 and M5.25588710 SNPs were considered environmentally stable and were not present in the
linkage blocks, showing their high potential for use in marker-assisted selection for grain yield in Brazilian rice breeding programs.
RESUMO - O objetivo deste trabalho foi identificar locos de características quantitativas (QTLs) associados à produtividade em uma população segregante de arroz (GYP). Uma população de 245 linhagens puras recombinantes de arroz, do cruzamento 'Epagri 108' (Oryza sativa subsp. indica) x 'IRAT 122' (O. sativa subsp. japonica), foi avaliada em diferentes locais e anos e genotipada por marcadores de polimorfismo de nucleotídeo único (SNPs). Obteve‑se um mapa de 1.592,8 cM a partir de 9.831 SNPs, tendo-se identificado 25 QTLs. Os seguintes nove SNPs apresentaram estabilidade entre os diferentes ambientes: M1.37719614 e M6.9563117 para GYP; M4.29340056, M5.25588710, M7.29115624 e M12.4534450 para peso de 100 grãos (HGW); e M1.38398157, M4.28368337 e M7.25991230 para altura de plantas. Seis SNPs não estavam presentes nos blocos de ligação: M6.9563117 e M4.1077080 para GYP; M5.25588710 e M6.8886398 para HGW; e M2.34471005 e M8.5955948 para altura de plantas. Os SNPs M6.9563117 e M5.25588710 foram considerados ambientalmente estáveis e não estiveram presentes em blocos de ligação, o que indica seu alto potencial para uso na seleção assistida por marcadores de produtividade de grãos, em programas brasileiros de melhoramento de arroz.

Abstract:The objective of this study was to verify the presence of small ruminant lentivirus in the amniotic fluid of goats using molecular tests and viral isolation by cocultivation in the amniotic fluid of naturally infected goats. The study analyzed eight goats: seven were small ruminant lentivirus-positive and one was negative. The amniotic fluid was collected from each of the eight animals during cesarean section at 147 days of pregnancy. Cocultivation was undertaken using secondary goat nictitating membrane cell cultures obtained by explant from a small ruminant lentivirus-negative calf followed by trypsinization and sub-cultivation of the cells for 63 days. During this period, five supernatant collections were performed for DNA extraction and subsequent nested polymerase chain reaction. DNA was extracted from the amniotic fluid after 3 h of cellular sedimentation, from which a sample of 600 ?L was taken from the sediment and another 600 ?L sample from the supernatant. After DNA extraction, nested polymerase chain reaction was performed. Of the eight goats, 62.5 % (05/08) were small ruminant lentivirus-positive, with 43.75 % (07/16) of the total samples positive when considering the two repetitions (supernatant and cell sediment). Moreover, positivity was confirmed by small ruminant lentivirus pro-viral DNA amplification in the cell supernatant throughout the cocultivation period. Small ruminant lentivirus were present in the amniotic fluid samples from the naturally infected goats indicating an intrauterine transmission route. Moreover, this biological fluid can be adopted for the diagnosis of these lentiviruse because it is an important risk factor related to intrauterine transmission.
