Slot Blot Hybridization

The use of genomic slot blot hybridization enabled the differentiation of hybrids from selfs in Saccharum × Erianthus intergeneric crosses in which Saccharum was used as the female parent. Based on the genomic in situ hybridization technique, slot blots of DNA from the parents and the progeny were blocked with the Saccharum parent DNA and hybridized with the labelled male Erianthus genomic DNA. This technique allowed a rapid screening for hybrids and was sensitive enough to detect a 1/20 dilution of Erianthus in Saccharum DNA, which should enable the detection of most partial hybrids. The genomic slot blot hybridization technique was shown to be potentially useful for assessing crosses involving Saccharum species with either Old World Erianthus section Ripidium or North American Erianthus (= Saccharum) species. The effectiveness of the technique was assessed on 144 progeny of a Saccharum officinarum × Erianthus arundinaceus cross, revealing that 43% of the progeny were selfs. The importance of this test as a tool to support intergeneric breeding programs is discussed.Key words: slot blot, Erianthus, genomic DNA, Saccharum, sugarcane.

Cauliflower mosaic virus (CaMV) gene VI protein (P6) is an important determinant of symptom expression. Differential display polymerase chain reaction (PCR) was used to identify changes in gene expression in Arabidopsis elicited by a P6 transgene that causes a symptomatic phenotype. We used slot blot hybridization to measure the abundance of mRNAs complementary to 66 candidate PCR products in transgenic, CaMV-infected, and uninfected Arabidopsis plants. CaMV-infected and P6 transgenic plants showed broadly similar changes in abundance of mRNA species. In P6 transgenic plants we detected 18 PCR products that showed unambiguous changes in abundance plus another 15 that showed more limited changes (approximately twofold). CaMV-infected plants showed 17 unambiguous and 13 limited changes. Down-regulated species include those encoding a novel, phenol-like sulfotransferase, and a glycine-rich, RNA-binding protein. Up-regulated species included ones encoding an myb protein, glycine-rich and stress-inducible proteins, and a member of a previously unreported gene family. CaMV infection causes alterations in expression of many Arabidopsis genes. Transgene-mediated expression of P6 mimics virus infection in its effect on host gene expression, providing a potential mechanism for this process.

Sulfated Glycoprotein

This study determined effects of day of oestrous cycle and early pregnancy on sulfated glycoprotein-1 (SGP-1) expression in ovine endometrium. A 364-bp clone of the ovine SGP-1 mRNA was amplified from reverse transcribed Day-15 cyclic endometrial mRNA using the polymerase chain reaction (PCR) and primers specific for the rat SGP-1 mRNA sequence. Nucleotide sequence of the ovine SGP-1 cDNA shared significant identity with rat SGP-1 and human prosaposin. Ewes (n = 40) were hysterectomized on either Day 1, 6, 11, 13 or 15 of the oestrous cycle or on Day 11, 13, 15, 17 or 25 of early pregnancy. Total cellular RNA was isolated from endometrium and subjected to Northern and slot blot hybridization analyses using an antisense cRNA probe transcribed from the ovine SGP-1 cDNA clone. A single 2.6-kb mRNA transcript was detected by Northern hybridization analyses. Slot blot hybridization analyses indicated that steady-state levels of endometrial SGP-1 mRNA varied during the oestrous cycle (cubic, P < 0.02) and increased between Day 11 and Day 25 of early pregnancy (linear, P < 0.01). On Days 11, 13 and 15, endometrial SGP-1 mRNA levels were greater in pregnant ewes than in cyclic ewes (day x pregnancy status, P < 0.01). Immunohistochemical localization of SGP-1 in uterine tissues with rabbit anti-rat SGP-1 antibody revealed intense immunoreactivity associated primarily with the endometrial epithelium. These results indicate that the ovine endometrium expresses SGP-1, a prosaposin, and that SGP-1 expression varies during the oestrous cycle and is enhanced by the conceptus. The presence of SGP-1 in the endometrium suggests intracellular and extracellular roles for this protein in glycosphingolipid metabolism or transport in the uterine environment.

Abstract Twenty-eight patients undergoing bone marrow transplantation (BMT) were followed-up at weekly intervals from day -10 to discharge from hospital after BMT for human cytomegalovirus (HCMV) infection using polymerase chain reaction (PCR), slot-blot hybridization, and conventional virus culture. High specificity of the PCR assay applied could be shown by failure to amplify DNA extracted from a wide range of other viruses frequently infecting marrow transplant recipients. The PCR technique allowed us to diagnose viremia and viruria in 20 (83%) of 24 seropositive patients after BMT, whereas culture assays showed 16 (67%) of 24 of these patients to be viruric and 9 (37%) of 24 cases to be viremic. Slot-blot hybridization showed a frequency of viruria and viremia in 12 (50%) of 24 seropositive patients. By application of PCR techniques, HCMV detection could be achieved even in the very early posttransplant period. HCMV was detected in five patients even before the onset of clinical symptoms of acute graft-versus-host disease. Analysis by PCR techniques of 33 organ biopsy specimens from patients after BMT showed the presence of HCMV in 13 of 14 liver samples obtained from patients with HCMV viremia; three liver specimens from patients without viremia were negative by all the techniques applied. HCMV could also be demonstrated in postmortem lung biopsy specimens from all patients (n = 10) with interstitial pneumonia.
