Genome-wide association for heat tolerance at seedling stage in historical spring wheat cultivars by Khan, Muhammad Ibrar, Kainat, Zarnishal, Maqbool, Saman, Mehwish, Ambreen, Ahmad, Suhaib, Hafiz Muhammad Suleman, Mahmood, Zahid, Ali, Mohsin, Aziz, Abdul, Rasheed, Awais, Huihui Li

“…An experiment was conducted to characterize 194 historical wheat cultivars of Pakistan under high temperature at seedling stage to identify loci associated with heat tolerance using genome-wide association studies (GWAS). A quantitative trait locus, TaHST1, on chr4A was also characterized to identify the haplotypes at this locus associated with heat tolerance in wheat from Pakistan. …”

Resistencia genética del frijol común al gorgojo mexicano de almacén Zabrotes subfasciatus [Boheman (Coleóptera: Chrysomelidae)] by Lemus A., Delmer G.

“…Para la identificación de genes asociados al locus APA, se utilizó la amplificación del ADN mediante la reacción en cadena de la polimerasa (PCR, siglas en inglés), y la variante optimizada cuantitativa en tiempo real (qPCR, siglas en inglés), para lo cual se usaron cuatro cebadores tipo SCAR, arcelina-like2 (ARL2), arcelina (ARC), inhibidor de α-amilasa (α-Al) y fitohemaglutinina (PHA). …”

Ontogenetic characteristics and inheritance of resistance to leaf anthracnose in sorghum by Tenkouano, A., Miller, F.R., Fredericksen, R.A., Nicholson, R.L.

“…The frequency distribution of disease severity indices was bimodal and fitted a 3:1 segregation, suggesting that resistance was controlled by dominance at a single multiallelic locus. The symbol egl was proposed to designate the resistance locus.…”

Effect of the black sigatoka resistance gene bs1 and ploidy level in fruit and bunch traits of plantain banana hybrids by Craenen, K., Ortíz, R.

“…As a result of the gene interaction in the black sigatoka resistance locus bs1, the partially resistant and less susceptible phenotypes showed higher yield than their more susceptible full sibs.…”

Microsatellites in cassava (Manihot esculenta Crantz) : discovery, inheritance and variability by Chavarriaga Aguirre, Paul, Maya, M.M., Bonierbale, Merideth W., Kresovich, Stephen, Fregene, Martin A., Tohme, Joseph M., Kochert, G

“…Linkage was detected between loci segregating from either parent, and segregation distortion from the male parent was detected for locus GA-131. Approximately 80% of the microsatellites detected one or two alleles per accession, suggesting a low degree of microsatellite locus duplication, an unexpected finding for a putative allopolyploid, highly heterozygous species. …”

Bovine alloreactive cytotoxic T cells by Teale, A.J., Morrison, W. Ivan, Spooner, R.L., Goddeeris, Bruno M., Groocock, C.M., Stagg, D.A.

“…In some cases, cytotoxic T cells were generated and their target specificity suggested that products of a second cell-mediated lympholysis-controlling locus in cattle were being detected. The nature of these products is not known.…”

QTL analysis of yield traits in an advanced backcross population derived from a cultivated Andean x wild common bean (Phaseolus vulgaris L.) cross by Blair, Matthew W., Iriarte Solórzano, G.A., Beebe, Stephen E.

“…Segregation distortion was most significant in regions orthologous for a seed coat color locus (R-C) on linkage group b08 and two domestication syndrome genes, one on linkage group b01 at the determinacy (fin) locus and the other on linkage group b02 at the seed-shattering (st) locus. …”

Marcadores SCAR y RAPD para la resistencia a la bacteriosis común (CBB) del frijol by Pedraza García, Fabio, Gallego Sánchez, Gerardo J., Beebe, Stephen E., Tohme, Joseph M.

“…Se observó que este par de cebadores amplifican sólo un locus en el parental resistente (SEL 1309) y ninguno en el susceptible (DOR 476), este locus es también inequívocamente amplificado a partir de los genomas de XAN 159 y de la accesión G 40020 de P. acutifolius usada como fuente primaria de resistencia, confirmando los resultados obtenidos mediante la técnica RAPD. …”

Variation in mutation dynamics across the maize genome as a function of regional and flanking base composition by Morton, B., Vroh Bi, Irie, McMullen, M., Gaut, B.

“…We also observe a relationship between locus A + T content and GC → AT pressure. This regional effect is in opposition to the influence of the two immediate neighbors in that GC → AT pressure increases with increasing locus A + T content but decreases with increasing flanking base A + T content and may represent a relationship between genome location and mutation bias. …”

Characterization of a putative rice mutant for reaction to rice tungro disease by Zenna, N.S., Cabauatan, P.Q., Baraoidan, M., Leung, H., Choi, I.-R.

“…All F1 plants were susceptible to RTSV, whereas F2 and F3 progenies segregated into resistant and susceptible phenotypes in a 1:3 ratio, indicating that the resistance is controlled by a single recessive locus. Most of the F3 lines resistant to RTSV were also GLH resistant, suggesting that the resistance to RTSV and GLH was governed by the same locus. …”

Colonization by the endophyte Piriformospora indica leads to early flowering in Arabidopsis thaliana likely by triggering gibberellin biosynthesis by Kim, D., Abdelaziz, M.E., Ntui, V.O., Guo, X., Al-Babili, S.

“…P. indica inoculated Arabidopsis plants displayed significant early flowering phenotype. qRT-PCR analysis of colonized plants revealed an up-regulation of flowering regulatory (FLOWERING LOCUS T, LEAFY, and APETALA1) and gibberellin biosynthetic (Gibberellin 20-Oxidase2, Gibberellin 3-Oxidase1 and Gibberellin requiring1) genes, while the flowering-repressing gene FLOWERING LOCUS C was down regulated. …”

Analysis of the biological role of prion-related Shadoo protein on early mouse embryogenesis by Chachondia, Kadambari

“…This suggested a physical linkage between the transgene integration site and Prnp locus. Indeed, the transgene integration site was found to be located within an intron of the mouse Api5 gene, at 37.5 Mbof thePrnp locus. …”
