| Abstract | BAK1 is a leucine-rich repeat receptor-like kinase that functions as a coreceptor with the brassinosteroid (BR) receptor BRI1 and the flagellin receptor FLS2, and as a negative regulator of programmed cell death. BAK1 has been shown to autophosphorylate on numerous serine/threonine sites in vitro as well as to transphosphorylate associated receptor kinases both in vitro and in planta. In the present study we identify Tyr-610 in the carboxyl-terminal domain of BAK1 as a major site of autophosphorylation that is brassinolide-induced in vivo and requires a kinase-active BAK1. Expression of BAK1(Y610F)-Flag in transgenic plants lacking the endogenous bak1 and its functional paralogue, bkk1, produced plants that were viable but extremely small and generally resembled BR signaling mutants, whereas an acidic substitution for Tyr-610 to mimic phosphorylation restored normal growth. Several lines of evidence support the notion that BR signaling is impaired in the BAK1(Y610F)-Flag plants, and are consistent with the recently proposed sequential transphosphorylation model for BRI1/BAK1 interaction and activation. In contrast, the FLS2-mediated inhibition of seedling growth by the flg22 elicitor occurred normally in the Y610F-directed mutant. However, expression of many defense genes was dramatically reduced in BAK1(Y610F) plants and the nonpathogenic hrpA mutant of Pseudomonas syringae was able to grow rapidly in the mutant. These results indicate that phosphorylation of Tyr-610 is required for some but not all functions of BAK1, and adds significantly to the emerging notion that tyrosine phosphorylation could play an important role in plant receptor kinase signaling. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
