Transcriptional signatures associated with waterlogging stress responses and aerenchyma formation in barley root tissue.

ABSTRACT:

Background and aims

The frequency of extreme precipitation events is predicted to increase owing to climate change, leading to soil waterlogging and crop yield losses, particularly in the case of susceptible species, such as barley (Hordeum vulgare). Aerenchyma formation is a key morphological adaptation to waterlogging stress and hypoxic conditions; however, its genetic regulation in barley remains largely unresolved. The aim of this study was to address this knowledge gap and characterize the transcriptional signatures associated with the waterlogging stress response and aerenchyma formation in barley roots.

Methods

Two barley cultivars (Franklin and Yerong) were subjected to waterlogging stress, followed by analysis of phenotypic traits, including root aerenchyma formatio
