A methodological approach for the construction of a radiation hybrid map of bovine chromosome 5 Genet. Mol. Biol.
De Donato,M.; Brenneman,R.A.; Stelly,D.M.; Womack,J.E.; Taylor,J.F..
A bovine 5,000 rad WG-RH panel was used to construct an RH map of bovine chromosome 5 (BTA5). Twenty-one microsatellites and thirteen genes were scored in the panel using PAGE and radioactive labeling. Marker retention ranged from 8.9%-25.8% and averaged 17.8%. Pairwise locus analysis placed all markers in a single syntenic group with a LOD support of 4.0. At a LOD support of 8.0, a centromeric group of 23 syntenic markers was formed. Telomeric groups of 11 and 9 markers were assembled with a LOD support of 6.0 and 8.0, respectively. All markers were ordered by maximum likelihood methods using the program RHMAP. Only 13 markers were ordered with a LOD support of at least 3.0, while 25 and 29 markers were ordered with a support of at least 2.0 and 1.0,...

Characterization and mapping of a spotted leaf mutant in rice (Oryza sativa) Genet. Mol. Biol.
Xu,Xue; Zhang,Lili; Liu,Binmei; Ye,Yafeng; Wu,Yuejin.
Spotted leaf mutant belongs to a class of mutants that can produce necrotic lesions spontaneously in plants without any attack by pathogens. These mutants have no beneficial effect on plant productivity but provide a unique opportunity to study programmed cell death in plant defense responses. A novel rice spotted leaf mutant (spl30) was isolated through low-energy heavy ion irradiation. Lesion expression was sensitive to light and humidity. The spl30 mutant caused a decrease in chlorophyll and soluble protein content, with marked accumulation of reactive oxygen species (ROS) around the lesions. In addition, the spl30 mutant significantly enhanced resistance to rice bacterial blight (X. oryzae pv. oryzae) from China (C1-C7). The use of SSR markers showed...

Genetic engineering applications in animal breeding Electron. J. Biotechnol.
Montaldo,Hugo H..
This paper discusses the use of genetic engineering applications in animal breeding, including a description of the methods, their potential and current uses and ethical issues. Genetic engineering is the name of a group of techniques used to identify, replicate, modify and transfer the genetic material of cells, tissues or complete organisms. Important applications of genetic engineering in animal breeding are: 1) Marker-assisted selection (MAS). The objective of this technology is to increase disease resistance, productivity and product quality in economically important animals by adding information of DNA markers to phenotypes and genealogies for selection decisions. 2) Transgenesis, the direct transfer of specific genes/alleles between individuals,...

Mapping and allelic sequencing of a long sterile lemma trait in rice Bragantia
Jiang,Liangrong; Zhu,Zhenzhong; Huang,Rongyu; Huang,Yumin; Wang,Houcong; Zheng,Jingsheng; Fang,Xunjun.
ABSTRACT Some outer floral organs are unique in gramineous plants, like the sterile lemma and rudimentary glume in rice. However, their development mechanisms are still poorly understood. In this study, we used 4 mutants with long sterile lemma (LSL), named JF11, JF12, JF13 and JNY-7, to be crossed with Aijiaonante (AJNT) and Nipponbare (NIP), respectively. Genetic analysis indicated that LSL trait exhibited recessive heredity and was controlled by a common allele named sl-1(t). Using the method of bulk segregant analysis and linkage analysis between SSR markers and LSL trait based on F2 populations, the sl-1(t) gene was located at the interval between RM20903 and RM20948 on chromosome 7. The interval harbors a known G1 gene, which regulates the sterile...

Sequence characterization, in silico mapping and cytosine methylation analysis of markers linked to apospory in Paspalum notatum Genet. Mol. Biol.
Podio,Maricel; Rodríguez,María P.; Felitti,Silvina; Stein,Juliana; Martínez,Eric J.; Siena,Lorena A.; Quarin,Camilo L.; Pessino,Silvina C.; Ortiz,Juan Pablo A..
In previous studies we reported the identification of several AFLP, RAPD and RFLP molecular markers linked to apospory in Paspalum notatum. The objective of this work was to sequence these markers, obtain their flanking regions by chromosome walking and perform an in silico mapping analysis in rice and maize. The methylation status of two apospory-related sequences was also assessed using methylation-sensitive RFLP experiments. Fourteen molecular markers were analyzed and several protein-coding sequences were identified. Copy number estimates and RFLP linkage analysis showed that the sequence PnMAI3 displayed 2-4 copies per genome and linkage to apospory. Extension of this marker by chromosome walking revealed an additional protein-coding sequence mapping...

Three novel polymorphic microsatellite markers for the glaucoma locus GLC1B by datamining tetranucleotide repeats on chromosome 2p12-q12 Genet. Mol. Biol.
Murga-Zamalloa,Carlos; Guevara-Fujita,Maria Luisa; Estrada-Cuzcano,Alejandro; Fujita,Ricardo.
In order to identify new markers around the glaucoma locus GLC1B as a tool to refine its critical region at 2p11.2-2q11.2, we searched the critical region sequence obtained from the UCSC database for tetranucleotide (GATA)n and (GTCT)n repeats of at least 10 units in length. Three out of four potential microsatellite loci were found to be polymorphic, heterozygosity ranging from 64.56% to 79.59%. The identified markers are useful not only for GLC1B locus but also for the study of other disease loci at 2p11.2-2q11.2, a region with scarcity of microsatellite markers.
