Directed proteomics identifies a plant-specific protein rapidly phosphorylated in response to bacterial and fungal elicitors.
The perception of microbial signal molecules is part of the strategy evolved by plants to survive attacks by potential pathogens. To gain a more complete understanding of the early signaling eventsExpand
Evidence for N- and C-terminal processing of a plant defense-related enzyme: Primary structure of tobacco prepro-beta-1,3-glucanase.
Tobacco glucan endo-1,3-beta-glucosidase (beta-1,3-glucanase; 1,3-beta-D-glucan glucanohydrolase; EC exhibits complex hormonal and developmental regulation and is induced when plants areExpand
Regulation of a plant pathogenesis-related enzyme: Inhibition of chitinase and chitinase mRNA accumulation in cultured tobacco tissues by auxin and cytokinin.
Two endochitinases (EC of M(r) values of approximately 34,000 and approximately 32,000 have been purified from cultured tissues of Nicotiana tabacum cv. Havana 425. The chitinase content ofExpand
MicroRNA-Mediated Regulation of Stomatal Development in Arabidopsis[W][OA]
The proper number and distribution of stomata are essential for the efficient exchange of gases between the atmosphere and the aerial parts of plants. We show that the density and development ofExpand
miR393 and Secondary siRNAs Regulate Expression of the TIR1/AFB2 Auxin Receptor Clade and Auxin-Related Development of Arabidopsis Leaves1[W][OA]
The phytohormone auxin is a key regulator of plant growth and development that exerts its functions through F-box receptors. Arabidopsis (Arabidopsis thaliana) has four partially redundant of theseExpand
A short C-terminal sequence is necessary and sufficient for the targeting of chitinases to the plant vacuole.
Tobacco contains different isoforms of chitinase (EC, a hydrolase thought to be involved in the defense against pathogens. Deduced amino acid sequences for putatively vacuolar, basicExpand
Movement of plant viruses is delayed in a beta-1,3-glucanase-deficient mutant showing a reduced plasmodesmatal size exclusion limit and enhanced callose deposition.
Susceptibility to virus infection is decreased in a class I beta-1,3-glucanase (GLU I)-deficient mutant (TAG4.4) of tobacco generated by antisense transformation. TAG4.4 exhibited delayedExpand
Isolation of complementary DNA clones encoding pathogenesis-related proteins P and Q, two acidic chitinases from tobacco.
Complementary DNA clones encoding two isoforms of the acidic endochitinase (chitinase, EC from tobacco were isolated. Comparison of amino acid sequences deduced from the cDNA clones and theExpand
Developmentally regulated silencing and reactivation of tobacco chitinase transgene expression
The tobacco class I chitinase gene CHN48 driven by CaMV 35S RNA expression signals introduced into Nicotiana sylvestris can inactivate its own expression as well as expression of homologous hostExpand
A revised nomenclature for chitinase genes
The nomenclature for chitinase genes has been revised to correspond to the nomenclature of PR-proteins and to distinguish classes from families. Accordingly, there are now four families ofExpand
