摘要： The present invention provides methods and materials that enhance a plant's resistance to certain pathogens. A novel pathway is described and has been designated with the acronym, SI-SAR pathway, for salicylic acid-independent systemic acquired resistance. DNA constructs and methodologies are provided that facilitate the identification of compounds that activate this pathway. Methods are provided to enable the identification of novel genes and signaling components that are expressed when the SI-SAR pathway is activated. Transgenic plants with altered expression of these novel genes or signaling components of the pathway are expected to have enhanced resistance to plant pathogens. Also provided is a novel, pathogen-induced epoxide hydrolase that is inducible in the absence of SA.

摘要： A salicylic acid-induced protein (SIP) kinase is disclosed. The kinase has a molecular weight of about 48 kDa and is activated in response to salicylic acid, H.sub.2 O.sub.2 and infection with tobacco mosaic virus. The activation and enzymatic properties of the purified protein have been characterized. The partial amino acid sequence and complete nucleotide sequence of a cDNA encoding the SIP kinase demonstrate that it is a unique member of the mitogen-activated protein (MAP) kinase family. The novel SIP kinase may play a critical role in signal transduction for activation of plant defenses against microbial pathogens.

摘要： An isolated nucleic acid molecule is provided which encodes a tobacco myb homologue involved in the regulation of disease resistance in plants. The encoded protein comprises a basic N-terminal region with two imperfect tryptophan repeats of 53 and 51 amino acids, a potential ATP/GTP binding site or P-loop, a redox sensitive cysteine and a nuclear localization sequence. The acidic C terminus of Myb1 forms amphipathic .alpha. helices which are characteristic of transcriptional activation domains. The invention also provides novel Myb1 protein and antibodies thereto. Additionally, the invention provides novel transgenic plants with enhanced disease resistance to certain pathogens.

摘要： A high-affinity salicylic acid-binding protein (SABP2) derivable from tobacco and Arabidopsis is disclosed. The tobacco protein has a molecular weight of approximately 25 kDa and reversibly binds SA with an apparent K.sub.d of approximately 90 nM and a B.sub.max of 10 fmol/mg protein. The SABP2 of the invention may be used to identify analogues of SA. Analogues so identified may be used in plants to augment disease-resistance response pathways or other SA-sensitive processes in which SA plays a role. Possible examples include flowering and alternative respiration. The SABP2 of the invention may also be used to identify and clone a gene or cDNA that encodes it, which then may be used to generate transgenic plants having altered SABP2 levels.
