Dado la presión por urbanizar áreas con presencia de suelos salino-sódicos (SSS) alrededor del ex lago Texcoco, México, es importante encontrar estrategias para arborizarlas. El objetivo estudio fue determinar respuesta cinco especies arbóreas; Pinus greggii, P. pseudostrobus, ayacahuite, leiophylla y como especie referencia Psidium guajava, establecidas en cepas un sustrato alternativo (CSA) S...

activity of these two cytokines is neutralized. Specific alleles of the human IL1RN were found to be associated with chronic hypochlorhydric response to Helicobacter pylori infection and the risk of gastric cancer [4], and with severe clinical symptoms in several chronic inflammatory diseases, including systemic lupus erythematosus [5], ulcerative colitis [6] and alopecia areata [7]. Two SNPs w...

Soil samples collected from a fallow field which had not been cultivated for 5 years harbored a population of Agrobacterium spp. estimated at 3 x 10 CFU/g. Characterization of 72 strains selected from four different isolation media showed the presence of biovar 1 (56%) and bv. 2 (44%) strains. Pathogenicity assays on five different test plants revealed a high proportion (33%) of tumorigenic str...

(SWR x New Zealand Black (NZB))F(1) (or SNF(1)) mice succumb to lupus nephritis. Although several NZB lupus susceptibility loci have been identified in other crosses, the potential genetic contributions of SWR to lupus remain unknown. To ascertain this, a panel of 86 NZB x F(1) backcross mice was immunophenotyped and genome scanned. Linkage analysis revealed four dominant SWR susceptibility loc...

Excessive amounts of metal are toxic and severely affect plant growth and development. Understanding the genetic control of metal tolerance is crucial to improve rice resistance to Fe, Zn, and Al toxicity. The multi-parent advanced generation inter-cross (MAGIC) populations were genotyped using a 55 K rice SNP array and screened at the seedling stage for Fe, Zn, and Al toxicity using a hydropon...

PR-domain 9 (Prdm9) is the first hybrid sterility gene identified in mammals. The incompatibility between Prdm9 from Mus musculus domesticus (Mmd; the B6 strain) and the Hstx2 region of chromosome (Chr) X from M. m. musculus (Mmm; the PWD strain) participates in the complete meiotic arrest of mouse intersubspecific (PWD×B6)F1 hybrid males. Other studies suggest that also semisterile intersubspe...

Constraint Handling Rules (CHR) [1] has become a general-purpose rule-based programming language throughout the last decade. The relations to many other formalisms have been investigated [2] and often results could be transferred from CHR to other formalisms, or vice versa. Graph Transformation Systems (GTS) [3], which have been developed in the 60ies and have become increasingly popular, have ...

OBJECTIVE Introduction of genes targeted in 129/Sv embryonic stem (ES) cells into NOD mice brings about linked genes that may modulate type 1 diabetes. Our objective was to identify 129S1/SvJ non-MHC regions contributing type 1 diabetes resistance or susceptibility in backcross to NOD/LtJ. RESEARCH DESIGN AND METHODS After congenic transfer of the NOD H2(g7) haplotype onto 129S1/Sv, 310 femal...

Nonalcoholic fatty liver disease (NAFLD) is a highly prevalent form of human hepatic disease and feeding mice a high-fat, high-caloric (HFHC) diet is a standard model of NAFLD. To better understand the genetic basis of NAFLD, we conducted an expression quantitative trait locus (eQTL) analysis of mice fed a HFHC diet. Two-hundred sixty-five (A/J × C57BL/6J) F2 male mice were fed a HFHC diet for ...

Numerous mouse models of polycystic kidney disease (PKD) have been described in which the mutant phenotypes closely resemble human PKD with regard to morphology, cyst localization, and disease progression. As in human PKD, genetic background affects the disease phenotype in mouse PKD models. Using experimental crosses, these modifying effects can be dissected into discrete genetic factors refer...
