Identifying and characterizing cold responsive genes in associated with or responsible for low temperature tolerance is a vital part of strawberry cultivar development. In this study we have investigated the transcript levels of eight genes, two dehydrin genes, three putative ABA-regulated genes, two cold-inducible CBF genes and the alcohol dehydrogenase gene, extracted from leaf and crown tissues of three genotypes that vary in cold tolerance. Transcript levels of the CBF/DREB1 transcription factor exhibited stronger cold up-regulation in comparison to in all genotypes. Transcripts of were highly up-regulated in both crown and leaf tissues from all three genotypes. In the 'ALTA' genotype, transcripts were significantly higher in leaf than crown tissues and more than 10 to 20-fold greater than in the less cold-tolerant 'NCGR1363' and 'FDP817' genotypes. , containing the conserved ABRE promoter element, transcript was found to be cold-regulated in crowns. Direct comparison of the kinetics of transcript and protein accumulation of dehydrins was scrutinized. In all genotypes and organs, the changes of transcript levels generally preceded protein changes, while levels of COR47 protein accumulation preceded the increases in RNA in 'ALTA' crowns.

Brown rot is a disease that affects stone and pome fruit crops worldwide. It is caused by fungal members of the genus , mainly , and . This study presents evidence that, despite having a very similar battery of Cell Wall Degrading Enzymes (CWDEs), the three species behave differently during the early stages of infection, suggesting differences at the regulatory level, which could also explain the differences in host preference among the three species.

Background: Temozolomide (TMZ) treatment has demonstrated, but variable, impact on glioma prognosis. This study examines associations of survival with DNA repair gene germline polymorphisms among glioma patients who did and did not have TMZ treatment. Identifying genetic markers which sensitize tumor cells to TMZ could personalize therapy and improve outcomes.

is a major migratory invasive pest and is of global concern. Vitellogenesis, a crucial process for population multiplication in oviparous insects, is regulated by endocrine hormones. In this study, three primary responders to JH signaling, the JH receptor gene , and the downstream transcription factor and , were first cloned and identified.

Idiopathic pulmonary fibrosis is a fatal disease characterized by the TGF-β-dependent activation of lung fibroblasts, leading to excessive deposition of collagen proteins and progressive replacement of healthy lung with scar tissue. We and others have shown that TGF-β-mediated activation of the Mechanistic Target of Rapamycin Complex 1 (mTORC1) and downstream upregulation of Activating Transcription Factor 4 (ATF4) promote metabolic reprogramming in lung fibroblasts characterized by upregulation of the de synthesis of glycine, the most abundant amino acid found in collagen protein. Whether mTOR and ATF4 regulate other metabolic pathways in lung fibroblasts has not been explored.

Mosaic Analysis with Double Markers (MADM) represents a mouse genetic approach coupling differential fluorescent labeling to genetic manipulations in dividing cells and their lineages. MADM uniquely enables the generation and visualization of individual control or homozygous mutant cells in a heterozygous genetic environment. Among its diverse applications, MADM has been used to dissect cell-autonomous gene functions important for cortical development and neural development in general.
