Abstract Since years, research on SnRK1, the major cellular energy sensor in plants, has tried to define its role signalling. However, these attempts were notoriously hampered by lethality of a complete knockout SnRK1. Therefore, we generated an inducible amiRNA::SnRK1α2 snrk1α1 knock out background ( / α2 ) abolish SnRK1 activity understand systemic functions signalling under deprivation triggered extended night treatment. We analysed vivo phosphoproteome, proteome and metabolome found that...
Metabolic adjustment to changing environmental conditions, particularly balancing of growth and defense responses, is crucial for all organisms survive. The evolutionary conserved AMPK/Snf1/SnRK1 kinases are well-known metabolic master regulators in the low-energy response animals, yeast plants. They act at two different levels: by modulating activity key enzymes, massive transcriptional reprogramming. While first part well established, latter function only partially understood animals not...
Plants use different signalling pathways to respond external stimuli. Intracellular via calcium-dependent protein kinases (CDPKs) or mitogen-activated (MAPKs) present two major that are widely used react a changing environment. Both CDPK and MAPK known be involved in the of abiotic biotic stresses animal, yeast plant cells. Here, we show essential function CPK3 (At4g23650) for salt stress acclimation Arabidopsis thaliana, test crosstalk between salt-stress activated MAPKs MPK4 MPK6 response....
Abstract Potato (Solanum tuberosum) is highly water and space efficient but susceptible to abiotic stresses such as heat, drought, flooding, which are severely exacerbated by climate change. Our understanding of crop acclimation stress, however, remains limited. Here, we present a comprehensive molecular physiological high-throughput profiling potato tuberosum, cv. Désirée) under waterlogging applied single or in combinations designed mimic realistic future scenarios. Stress responses were...
Stress Knowledge Map (SKM; https://skm.nib.si) is a publicly available resource containing two complementary knowledge graphs that describe the current of biochemical, signaling, and regulatory molecular interactions in plants: highly curated model plant stress signaling (PSS; 543 reactions) large comprehensive network (488 390 interactions). Both were constructed by domain experts through systematic curation diverse literature database resources. SKM provides single entry point for...
Mitogen-activated protein kinase (MAPK) cascades are universal signal transduction modules present in all eukaryotes. In plants, MAPK were shown to regulate cell division, developmental processes, stress responses, and hormone pathways. The subgroup A of Arabidopsis MAPKs consists AtMPK3, AtMPK6, AtMPK10. AtMPK3 AtMPK6 activated by their upstream MAP kinases (MKKs) AtMKK4 AtMKK5 response biotic abiotic stress. addition, they identified as key regulators stomatal development patterning....
Calcium (Ca 2+ ) and reactive oxygen species (ROS) are key secondary messengers in plant stress signaling, yet their interplay regulating proteome–wide responses remains poorly understood. In this study, we employed label–free quantitative (LFQ) proteomics to investigate Ca –dependent independent changes the proteome of Arabidopsis thaliana leaves upon oxidative induced by hydrogen peroxide (H 2 O ). To dissect role inhibited H –induced transients pretreatment with LaCl 3 , a plasma membrane...
SUMMARY GERMIN3 has previously been identified as a target of the tuberigen activation complex, suggesting function in potato tuberisation, but its role is presently unknown. In present study, we analysed morphological, agronomic and molecular phenotypes transgenic lines Solanum tuberosum ssp. andigena cultivar Desiree. over‐expressing S. exhibited increased tuber yields enhanced numbers. Post‐harvest sprouting greater bud with numbers sprouts. Axillary buds were also activated aerial...
Plants rely on water and light for photosynthesis, but droplets leaves can focus into high-intensity spots, risking photodamage. Excessive impair growth or induce cell death, making it essential plants to detect respond fluctuations. While Ca2+ signaling has been linked high (HL) acclimation, the subcellular dynamics remain unclear. Here, we investigate responses HL exposure in Arabidopsis thaliana. Using a glass bead simulate light-focusing by droplets, biphasic increase of concentration...
Anabaena sp.strain PCC 7120 is a filamentous cyanobacterium commonly used as model organism for studying cyanobacterial cell differentiation and nitrogen fixation.For many decades, this was considered an obligate photo-lithoautotroph.We now discovered that strain also capable of mixotrophic, photo-organoheterotrophic, chemo-organoheterotrophic growth if high concentrations fructose (at least 50 mM up to 200 mM) are supplied.Glucose, substrate by some facultatively organoheterotrophic...

Plants require water and light for photosynthesis, but light, when focused by droplets on leaves, can create high intensity spots that are harmful to plants. As excessive reduce growth or even induce cell death, it is vital plants detect react changes in exposure acclimate stress. Ca2+ signaling was previously implicated acclimation. However, the dynamics of free concentration chloroplast, primary site nucleus cytoplasm, where transcription translation long term acclimation occurs, remain...
