Abstract
Understanding which intracellular signaling pathways are activated by manganese stress is crucial to decipher how metal overload compromise cellular integrity. Here, we unveil a role for oxidative and cell wall stress signaling in the response to manganese stress in yeast. We find that the oxidative stress transcription factor Yap1 protects cells against manganese toxicity. Conversely, extracellular manganese addition causes a rapid decay in Yap1 protein levels. In addition, manganese stress activates the MAPKs Hog1 and Slt2 (Mpk1) and leads to an up-regulation of the Slt2 downstream transcription factor target Rlm1. Importantly, Yap1 and Slt2 are both required to protect cells from oxidative stress in mutants impaired in manganese detoxification. Under such circumstances, Slt2 activation is enhanced upon Yap1 depletion suggesting an interplay between different stress signaling nodes to optimize cellular stress responses and manganese tolerance.

Abstract
Yeast adaptation to stress has been extensively studied. It involves large reprogramming of genome expression operated by many, more or less specific, transcription factors. Here, we review our current knowledge on the function of the eight Yap transcription factors (Yap1 to Yap8) in Saccharomyces cerevisiae, which were shown to be involved in various stress responses. More precisely, Yap1 is activated under oxidative stress, Yap2/Cad1 under cadmium, Yap4/Cin5 and Yap6 under osmotic shock, Yap5 under iron overload and Yap8/Arr1 by arsenic compounds. Yap3 and Yap7 seem to be involved in hydroquinone and nitrosative stresses, respectively. The data presented in this article illustrate how much knowledge on the function of these Yap transcription factors is advanced. The evolution of the Yap family and its roles in various pathogenic and non-pathogenic fungal species is discussed in the last section.

Front Microbiol 2019; 10:1073.

Abstract
Fusarium head blight caused by Fusarium graminearum is an important disease of wheat and barley. Previous studies have showed that all three MAP kinase genes, MGV1, FgHOG1, and GPMK1, are involved in regulating hyphal growth, sexual reproduction, plant infection, and stress responses in this pathogen. To determine the relationship between the Mgv1 and FgHog1 pathways, in this study, we generated and characterized the mgv1 Fghog1 double mutant. Deletion of FgHOG1 partially rescued the defects of the mgv1 mutant in vegetative growth and cell wall integrity but had no effects on its defects in plant infection and DON production. The mgv1 Fghog1 mutant grew faster and was more tolerant to cell wall stressors than the mgv1 mutant. Swollen compartments and cell burst were observed frequently in the mgv1 mutant but rarely in the mgv1 Fghog1 mutant when treated with fungicide fludioxonil or cell wall stressor Congo red. Conversely, the deletion of MGV1 also alleviated the hyperosmotic sensitivity of the Fghog1 mutant in vegetative growth. TGY assays indicated increased phosphorylation of FgHog1 in the mgv1 mutant, and TEY assays further revealed elevated activation of Gpmk1 in the mgv1 Fghog1 double mutant, particularly under cell wall stress conditions. Overall, our data showed that deletion of FgHOG1 partially suppressed the defects of the mgv1 mutant, possibly by affecting genes related to cell wall integrity and osmoregulation via the over-activation of Gpmk1 MAP kinase and avoiding intracellular turgor elevation.

Overexpression of RCK1 improves acetic acid tolerance in Saccharomyces cerevisiae. J Biotechnol 2019; 292:1-4. [PMID: 30615911 DOI: 10.1016/j.jbiotec.2018.12.013] [Citation(s) in RCA: 35] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/13/2018] [Revised: 12/06/2018] [Accepted: 12/26/2018] [Indexed: 11/23/2022]
Abstract
Mixed sugars derived from lignocellulosic biomass can be converted into biofuels and chemicals by engineered microorganisms, but toxic fermentation inhibitors produced from harsh depolymerization processes of lignocellulosic biomass pose a critical challenge for economic production of biofuels and chemicals. Unlike other fermentation inhibitors generated from sugar degradation, acetic acid is inevitably produced from acetylated hemicellulose, and its concentrations in cellulosic hydrolysates are substantially higher than other fermentation inhibitors. The aim of this study was to identify novel genetic perturbations for improved acetic acid tolerance in Saccharomyces cerevisiae. Through a genomic library-based approach, we identified an overexpression gene target RCK1 coding for a protein kinase involved in oxidative stress. Overexpression of RCK1 significantly improved glucose and xylose fermentation under acetic acid stress conditions. Specifically, the RCK1-overexpressing strain exhibited a two-fold higher specific ethanol productivity than the control strain in glucose fermentation under the presence of acetic acid. Interestingly, the engineered S. cerevisiae overexpressing RCK1 showed 40% lower intracellular reactive oxygen species (ROS) levels as compared to the parental strain when the strains were exposed to acetic acid, suggesting that RCK1 overexpression might play a role in reducing the oxidative stress caused by acetic acid.

Induction of Ptp2 and Cmp2 protein phosphatases is crucial for the adaptive response to ER stress in Saccharomyces cerevisiae. Sci Rep 2018; 8:13078.

Abstract
Expression control of the protein phosphatase is critically involved in crosstalk and feedback of the cellular signaling. In the budding yeast ER stress response, multiple signaling pathways are activated and play key roles in adaptive reactions. However, it remains unclear how the expression level of the protein phosphatase is modulated during ER stress response. Here, we show that ER stress increases expression of Ptp2 tyrosine phosphatase and Cmp2 calcineurin phosphatase. Upregulation of Ptp2 is due to transcriptional activation mediated by Mpk1 MAP kinase and Rlm1 transcription factor. This induction is important for Ptp2 to effectively downregulate the activity of Hog1 MAP kinase. The budding yeast genome possesses two genes, CMP2 and CNA1, encoding the catalytic subunit of calcineurin phosphatase. CMP2 is more important than CNA1 not only in ER stress response, but also in salt stress response. Higher promoter activity of CMP2 contributes to its relative functional significance in ER stress response, but is less important for salt stress response. Thus, our results suggest that expression control of Ptp2 and Cmp2 protein phosphatases at the promoter level is crucial for adaptive responses to ER stress.

Rck1 promotes pseudohyphal growth via the activation of Ubp3 phosphorylation in Saccharomyces cerevisiae. Biochem Biophys Res Commun 2016; 469:333-9.

Abstract
Previously, we reported that Rck1 up-regulates Ras2 and pseudohyphal growth of Saccharomyces cerevisiae. Here, we further investigate the involvement of Rck1 in the activation of pseudohyphal growth. Rck1 activated phosphorylation of the deubiquitinase Ubp3 through a direct protein interaction between Rck1 and Ubp3. The N-terminal Bre5 binding region of Ubp3 physically interacted with Rck1, and Ubp3 and Rck1 co-precipitated. Overexpression of UBP3 using a high-copy plasmid resulted in the upregulation of Ras2, and deletion of UBP3 blocked the upregulation of Ras2 by RCK1 overexpression. Treatment with the proteasome inhibitor MG132 resulted in accumulation of Ras2, indicating that Rck1 is involved in Ras2 degradation in a proteasome-dependent manner. Furthermore, deletion of UBP3 blocked the upregulation of FLO11, a flocculin required for pseudohyphal and invasive growth induced by RCK1 overexpression in S. cerevisiae. Taken together, these results demonstrate that Rck1 promotes S. cerevisiae pseudohyphal growth via the activation of Ubp3 phosphorylation.

Abstract
Yap2 is a cadmium responsive transcription factor that interacts with MAPK-activated protein (MAPKAP) kinase Rck1. We show that Rck1 deletion confers protection against cadmium toxicity and that the mechanism underlying this observation relies on Yap2. Rck1 removal from the yeast genome potentiates Yap2 activity by increasing protein half-life and delaying its nuclear export. As a consequence, several Yap2 antioxidant targets are over-activated by a mechanism that also requires Yap1. Several genes of the cell wall integrity (CWI) pathway are upregulated under cadmium stress in a Yap2 dependent way. We showed that deletion of CWI genes renders yeast cells more sensitive to cadmium. These findings led us to suggest that in response to cadmium stress Yap2 may serve a dual purpose: oxidative stress attenuation and cell wall maintenance.
