Purpose: The aim of the present study was to examine the genetic background of primary open angle glaucoma (POAG) in the Finnish population by analyzing previously reported candidate loci GLC1B on 2cen-q13, GLCIC on 3q21-q24, GLC1D on 8q23, GLC1F on 7q35-q36, as well as other candidate regions on chromosomes 2p14, 2q33-34, 10p12-13, 14q11, 14q21-22, 17p13, 17q25, and 19q12-14. In addition, we analysed loci for the MYOC gene on 1q23-24 and the OPTN gene on 10p14-15.
Methods: Eight Finnish families (92 family members; 27 individuals with POAG; 19 individuals with ocular hypertension or glaucoma suspicion) were genotyped using 35 microsatellite markers on the candidate loci and analyzed for linkage.
Results: No significant evidence for linkage was found in two point and multipoint linkage analyses to the tested markers in the analyzed families.
Conclusions: Our results support further genetic heterogeneity underlying POAG and encourage a search of novel genetic loci and predisposing genes in order to understand the genetic mechanisms underlying POAG.

Forward genetic screens of mutant populations are fundamental for functional genomics studies. However, isolating independent mutant alleles to molecularly identify causal genes is challenging in species recalcitrant to genetic manipulation. Here, we demonstrate that classic seed EMS mutagenesis coupled with genome sequencing can overcome this limitation in sorghum.

Soil alkalinization and global warming are predicted to pose major challenges to agriculture in the future, as they continue to accelerate, markedly reducing global arable land and crop yields. Therefore, strategies for future agriculture are needed to further improve globally cultivated, relatively high-yielding Green Revolution varieties (GRVs) derived from the SEMIDWARF 1 (SD1) gene. Here we propose that precise regulation of the phytohormone gibberellin (GA) to optimal levels is the key to not only confer alkali-thermal tolerance to GRVs, but also to further enhance their yield.

Panicle elongation length (PEL), which determines panicle exsertion, is an important outcrossing-related trait. Mining genes controlling PEL in rice (Oryza sativa L.) has great practical significance in breeding cytoplasmic male sterility (CMS) lines with increased PEL and simplified, high-efficiency seed production.

Objectives: This case-control study aims to clarify the impact of single nucleotide polymorphisms (SNPs) within the P2X7 gene on susceptibility to type 2 diabetes mellitus (T2DM) and to evaluate their association with diabetic complications.
Methods: This study is comprised with 200 T2DM cases and 200 healthy controls. Seven candidate SNP loci were screened, and TaqMan-MGB real-time PCR technology was used to determine the polymorphic variants of P2X7.
