The AREB1-ADA2b-GCN5 Complex Regulates Gene Expression during Drought Stress

Abiotic stresses constitute a global threat to agricultural crop production and natural ecosystems. One of the most prominent abiotic stresses is drought, which dramatically alters plant physiology and morphology. Studies in model organisms have shed light into how plants respond to drought stress, including transcriptional reprogramming of genes responsive to the hormone abscisic acid (ABA) […]

Worming into the Plant Chromatin: A Nematode Effector Influences Host Histone Acetylation

Plants encounter myriad invaders, including bacteria, fungi, insects, and other parasites. These pathogens generally deliver effector proteins into plants, increasing their virulence and targeting various host processes (Toruño et al., 2016). Although advances in the past two decades have led to significant insights into how pathogens achieve this task, research on plant pathogenesis predominantly has […]

Plant Systemic Immunity Comes Full Circle: A Positive Regulatory Loop for Defense Amplification

The plant immune system is effective in conferring resistance to various invading pathogens and pests. Membrane-localized pattern recognition receptors (PRRs) and intracellular nucleotide-binding domain, leucine-rich repeat proteins (NLRs) recognize pathogen-associated molecular patterns and pathogen virulence effectors, respectively, to initiate robust downstream responses that effectively contain or eliminate the invader. Infection at a local site with […]

CDL1-OST1 Interaction as a Focal Point of Brassinosteroid-Abscisic Acid Hormone Signaling Crosstalk

Plants integrate signals in the form of light, humidity, temperature, CO2 concentrations and daily circadian rhythms. In addition, plants encounter pathogens, pests, herbivores and other stressors. Physiological processes like responding to stimuli, plant growth and development are usually governed and coordinated by hormones. Because of the highly coordinated and complex nature of hormone signaling networks, […]

Heat Trims the Fat: HIL1 Functions in Lipid Homeostasis

Global climate change is one of the most pressing issues facing our world today. The impact of increasing temperatures can be felt in diverse areas, including human health and disease, natural ecosystems, and food security. In the agricultural sector, deciphering how plants respond to changing environmental conditions (e.g., heat stress) is key to eventually boosting […]
