    Antioxidant responses under salinity and drought in three wild monocots

    Some deleterious effects of drought, soil salinity and other abiotic stresses are mediated by the generation of oxidative stress through an increase in reactive oxygen species (ROS) that damage cellular membranes, proteins and DNA. In response to increased ROS, plants activate an array of enzymatic and non-enzymatic antioxidant defence responses. In a recent study published […] More

    Diuris population genomics

    Conservation of orchid species (Orchidaceae) can be challenging, particularly for a small Diuris group of four species from southeastern Australia. To determine best conservation practices for the four species, Ahrens et al. measured morphological features, and employed Next Generation Sequencing techniques to obtain thousands of Single Nucleotide Polymorphisms (SNPs). Morphological features did not align with […] More
