The answer, in large part, may lie with cell-specific differences in the expression and activation of various components of the MAPK network under different sets of circumstances. Lampard et al. devised a cell-specific assay for assessing the activity and regulation of MAPK modules in stomatal development based a panel of dominant-negative and constitutively active MAPKK variants expressed in discrete stomatal lineage cell types through the use of cell-type specific promoters. The approach was designed to allow investigation into cell-specific aspects of MAPK signaling without inducing pleiotropic phenotypes, which likely result from ubiquitous activation of MAPK signaling. The authors identified expanded roles for MKK4 and MKK5 in negative regulation of stomatal development and, unexpectedly, uncovered both positive and negative regulatory roles for MKK7 and MKK9 at different stages of stomatal development. MKK7 and MKK9 were found to function in inhibition of the first two stages of stomatal development and in promotion of guard cell proliferation at the terminal stages of stomatal development (see figure). The authors present a model of MAPK control of stomatal development that integrates developmental and environmental cues to offer a reasonable explanation of experimental results and highlight unknown components. This work provides significant insight into regulation of stomatal development and is also of broader significance to our understanding of MAPK networks. It shows that MAPK networks can be dissected by modulating the expression of individual components in specific cell types, in this case stomatal lineage cell types. This cell-specific approach should prove useful for the study of other complex signal transduction pathways as well.","PeriodicalId":22905,"journal":{"name":"The Plant Cell Online","volume":"11 1","pages":"3413 - 3413"},"PeriodicalIF":0.0,"publicationDate":"2009-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91120263","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Experiments with the Srlk-promoter fused to a b-glucuronidase marker gene showed that Srlk expression is strongly induced in root epidermal cells in response to salt. Repression of Srlk using RNA interference (RNAi) and mutations of Srlk introduced through TILLING prevented the inhibition of root growth under high salt conditions (see figure). In addition, Srlk mutant plants were found to accumulate significantly less sodium than control plants. Finally, several other salt-induced genes showed drastically reduced levels of induction following salt stress in the Srlk mutants relative to controls. RLKs possess an extracellular domain connected via a transmembrane domain to a cytoplasmic kinase. Plants contain hundreds of RLKs, which are thought to have overlapping or distinct roles in perceiving environmental and developmental signals and transducing these signals to downstream effectors (reviewed in Morillo and Tax, 2006). The results of de Lorenzo et al. suggest that Srlk may play a primary role in the perception of salt stress by M. truncatula roots and the ability of the plant to accumulate sodium under high salt conditions. Plant response to high salt and other stresses is highly complex, making genetic modification of plants for improved stress tolerance difficult to achieve (Wang et al., 2003). It will be important to identify downstream signaling partners and target genes of Srlk in the response and adaptation to salt stress. This work opens a new pathway for investigation and enhanced prospects for the development of improved salt tolerance in","PeriodicalId":22905,"journal":{"name":"The Plant Cell Online","volume":"87 1","pages":"364 - 364"},"PeriodicalIF":0.0,"publicationDate":"2009-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77570451","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
