Bacterial infections are a serious issue for crop plants and it is thus imperative to understand the mechanisms employed by plants to develop resistance against pathogens. Malukani et al. have identified a receptor kinase in rice, WALL-ASSOCIATED KINASE-LIKE 21 (OsWAKL21.2) that perceives pathogen-induced…

Host perception is crucial for soil-borne microbes to successfully colonize plant roots. Ding et al. conducted transcriptome analysis of the fungal pathogen Fusarium graminearum (Fg) in the presence of its host plant Brachypodium distachyon (Bd), either without direct contact (precontact) or during colonization.…

NPR1 (NONEXPRESSER OF PR GENES1) is a master regulator that controls expression of over 2000 genes during plant defense. NPR1 interacts with transcription factors to activate expression of defense genes, but the mechanism is poorly understood. Chen et al. determined that in the presence of salicylic…

Global environmental change brings new challenges to plants at different levels, including seed development and persistence. For example, the increasing ground-levels of ozone (O3) can affect seed viability, as a result of changes in the mother plant antioxidant machinery. These responses might depend…

Review: Evo-physio: on stress responses and the earliest land plants Streptophytes are a grade of mostly freshwater algae that transitioned into land, a singularity that in turn gave rise to all present terrestrial flora. This passage along the hydrological gradient that culminated in land habitation…

Magdalena M. Julkowska, King Abdullah University of Science and Technology, Thuwal, Saudi Arabia, ORCID: 0000-0002-4259-8296 [email protected] Water transport is essential for many physiological processes in vascular plants. One of the forces driving water transport across roots…

Over 450 million years of land plant evolution has led to the acquisition of diverse and often overlapping sets of defense responses that limit pathogen infection. Decades of research has uncovered canonical immune pathways that provide resistance to specialist (hemi)-biotrophic pathogens relying on…
