MetabolomicsCell type-specific proteomics uncovers a RAF15-SnRK2.6/OST1 kinase cascade in guard cells

Multicellular organisms such as plants contain various cell types with specialized functions. Analyzing the characteristics of each cell type reveals specific cell functions and enhances our understanding of organization and function at the organismal level. Guard cells (GCs) are specialized epid...

ProteomicsRebuilding core abscisic acid signaling pathways of Arabidopsis in yeast
The signaling pathway of the phytohormone abscisic acid (ABA) regulates responses towards abiotic stress such as drought and high osmotic conditions. The multitude of functionally redundant components involved in ABA signaling, poses a major challenge for elucidating the largely unresolved response ...

ProteomicsThe C-terminal domains SnRK2-box and ABA-box have a role in sugarcane SnRK2s auto-activation and activity
Resistance to drought stress is fundamental to plant survival and development. Abscisic acid (ABA) is one of the major hormones involved in different types of abiotic and biotic stress responses. ABA intracellular signaling has been extensively explored in Arabidopsis thaliana and occurs via a phosp...

ProteomicsOK-SnRK2 cascade mediates osmotic stress signaling in plant
Osmotic stress associated with drought, salinity and cold is a major factor limits plant productivity. A few signaling factors have been identified in the sensing or early signaling of osmotic stress. SNF1-related protein kinase 2 (SnRK2) are quickly activated by osmotic stress and the snrk2 decuple...

TranscriptomicsPathways leading to phosphorylation of p450c17 and to the post-translational regulation of androgen biosynthesis
Cytochrome P450c17 (P450c17) is the single enzyme that catalyzes steroid 17alpha-hydroxylase and 17,20 lyase activities and hence is the crucial decision-making step that determines the class of steroid made in a steroidogenic cell. Although both activities are catalyzed on a single active site, the...

ProteomicsProteomic profiling of human monocytes stimulated in vitro with N. meningitidis
Meningococcal sepsis is an overwhelming form of the sepsis syndrome which may cause mortality within 12-24 hours in previously healthy children and adults, where the causative infectious agent is N. meningitidis, an obligate human pathogen. The genomic changes induced by N. meningitidis are modulate...

ProteomicsDIA-based phosphoproteomics identifies early phosphorylation events in response to EGTA and mannitol in Arabidopsis
The rapid activation of RAF-SnRK2 cascades in response to hyperosmolarity is a crucial event in plants' adaptation to osmotic stress, yet the underlying mechanisms have remained elusive. In this study, we reveal that the calcium chelator EGTA, but not other calcium modulators, can potently activate ...
