Analysis of genotype × environment interactions for agronomic traits of soybean (Glycine max [L.] Merr.) using association mapping

Frontiers in Genetics, 2023
The soybean yield is a complex quantitative trait that is significantly influenced by environmental factors. G × E interaction (GEI), which derives the performance of soybean genotypes differentially in various environmental conditions, is one of the ...

Age-associated alterations in DNA methylation and expression of methyltransferase and demethylase genes in Arabidopsis thaliana

Biologia Plantarum, 2016
Little is known about the contributions of DNA methylation/demethylation to plant aging and senescence. We used Arabidopsis thaliana to study how increasing age of an annual plant species influences DNA methylation.

Measuring degradation of transgenic DNA and screening for horizontal gene transfer from GMO-plant material during composting [PDF]

, 2004
The experiments show that composting of GM plant residues greatly increases the rate of degradation of transgenic DNA compared to the rate for plant residues left in the soil.

40S ribosome biogenesis co-factors are essential for gametophyte and embryo development [PDF]

, 2013
Ribosome biogenesis is well described in Saccharomyces cerevisiae. In contrast only very little information is available on this pathway in plants. This study presents the characterization of five putative protein co-factors of ribosome biogenesis in ...

Amplification-free detection of plant pathogens by improved CRISPR-Cas12a systems: a case study on phytoplasma

Frontiers in Plant Science
CRISPR-based disease detection has the potential to profoundly change how pathogens are detected in plant materials. However, there has been a lack of research directed into improving explicitly the CRISPR components that define these detection assays ...

DNA demethylation by ROS1a in rice vegetative cells promotes methylation in sperm. [PDF]

, 2019
Epigenetic reprogramming is required for proper regulation of gene expression in eukaryotic organisms. In Arabidopsis, active DNA demethylation is crucial for seed viability, pollen function, and successful reproduction. The DEMETER (DME) DNA glycosylase

Plant and Human MORC Proteins Have DNA-Modifying Activities Similar to Type II Topoisomerases, but Require One or More Additional Factors for Full Activity

Molecular Plant-Microbe Interactions, 2017
To elucidate one or more mechanisms through which microrchidia (MORC) proteins impact immunity, epigenetic gene silencing, and DNA modifications, the enzymatic activities of plant MORCs were characterized.

Lead-induced DNA damage in Vicia faba root cells: Potential involvement of oxidative stress [PDF]

, 2011
Genotoxic effects of lead (0–20 µM) were investigated in whole-plant roots of Vicia faba L., grown hydroponically under controlled conditions. Lead-induced DNA damage in V.
