Plant growth, ion accumulation, and antioxidant enzymes of endophyte-infected and endophyte-free tall fescue to salinity stress
Endophyte-mediated salinity tolerance is largely unknown in tall fescue [Schedonorus arundinaceus (Schreb.)]. The experiment was designed to characterize growth, ion accumulation, and antioxidant metabolism of ta...

Article
Growth, ionic response, and gene expression of shoots and roots of perennial ryegrass under salinity stress
Growth, ionic responses, and expression of candidate genes to salinity stress were examined in two perennial ryegrass accessions differing in salinity tolerance. The salinity tolerant (PI265349) and sensitive ...

Open AccessGenome-wide association analysis and QTL map** reveal the genetic control of cadmium accumulation in maize leaf
Accumulation of cadmium (Cd) in maize (Zea mays L.) poses a significant risk to human health as it is ingested via the food chain. A genome-wide association study (GWAS) was conducted in a population of 269 maize...

The BRANCHING ENZYME1 gene, encoding a glycoside hydrolase family 13 protein, is required for in vitro plant regeneration in Arabidopsis
In vitro plant regeneration requires the coordinated action of various enzymes in addition to phytohormones. Here, we report that the Arabidopsis Branching Enzyme 1 (BE1) gene, encoding a putative glycoside hydro...
