Jasmonic acid (JA) and nitric oxide (NO) are well-characterized signaling molecules in plant defense responses. However, their roles in plant defense against root-knot nematode (RKN, Meloidogyne incognita) infection are largely unknown. In this study, we found that the transcript levels of the JA- and NO-related biosynthetic and signaling component genes were induced after RKN infection. Applic...
Jasmonate (JA) and ethylene (ET) are two major plant hormones that synergistically regulate plant development and tolerance to necrotrophic fungi. Both JA and ET induce the expression of several pathogenesis-related genes, while blocking either signaling pathway abolishes the induction of these genes by JA and ET alone or in combination. However, the molecular basis of JA/ET coaction and signal...
چکیده زیره سیاه (bunium persicum) گیاهی از خانواده چتریان (umbellifera) می باشد که به لحاظ برخورداری از ارزش دارویی واقتصادی بالا جایگاه ویژه ای را به خود اختصاص داده است. طولانی بودن طول دوره رویش، وجود خواب در بذر و نیاز به پیش تیمار سرما جهت جوانه زنی از موانع اساسی کشت زراعی این گیاه می باشد، لذا استفاده از تکنیک کشت بافت گیاهی جهت تکثیر و توسعه این گیاه دارویی ارزشمند ضروری به نظر می رسد....
System architecture, experimental settings and evaluation results of EHR group in the en-ja, zh-ja, JPCzh-ja and JPCko-ja tasks are described. Our system concept is combination of a rule based method and a statistical method. System combination of rule-based machine translation (RBMT), RBMT plus statistical post-editing (SPE) and preordering plus statistical machine translation (SMT) is conduct...
Different lepidopteran elicitors account for cross-talk in herbivory-induced phytohormone signaling.
Salicylic acid (SA), jasmonic acid (JA), ethylene (ET), and their interactions mediate plant responses to pathogen and herbivore attack. JA-SA and JA-ET cross-signaling are well studied, but little is known about SA-ET cross-signaling in plant-herbivore interactions. When the specialist herbivore tobacco hornworm (Manduca sexta) attacks Nicotiana attenuata, rapid and transient JA and ET bursts ...
The jasmonic acid (JA) signaling pathway plays important roles in adaptation of plants to environmental cues and in specific steps of their development, particularly in reproduction. Recent advances in metabolic studies have highlighted intricate mechanisms that govern enzymatic conversions within the jasmonate family. Here we analyzed jasmonate profile changes upon Arabidopsis thaliana flower ...
Background & aim: Recent researches have been done on effects of plant growth regulators (PGR) on growth and production of different crops whose results indicate the effectiveness of most of these hormones on qualitative and quantitative growth of herbs. The application of regulators and inhibitors of growth on herbs may, in addition to growth, also lead to secondary metabolites stimulation. Ja...
Yritysten välinen yhteistyö avoimessa palveluverkossa on yleistymässä. Luottamuksenhallinta tukee yhteistyötä ja edistää riskien hallintaa tilanteissa, joissa kumppanien väliset suhteet syntyvät ja katoavat varsin nopeasti. Palvelun laadun ja palveluntarjoajan luotettavuuden arvioimiseksi omiin kokemuksiin liitetään maineverkoston kautta myös muiden sen jäsenien kokemuksia, jolloin koko verkost...
Jasmonic acid (JA) is a critical hormonal regulator of plant growth and defense. To advance our understanding of the architecture and dynamic regulation of the JA gene regulatory network, we performed a high-resolution RNA-seq time series of methyl JA-treated Arabidopsis thaliana at 15 time points over a 16-h period. Computational analysis showed that methyl JA (MeJA) induces a burst of transcr...
Jasmonates are phytohormones involved in a wide range of plant processes, including growth, development, senescence, and defense. Jasmonoyl-L-isoleucine (JA-Ile, 2), an amino acid conjugate of jasmonic acid (JA, 1), has been identified as a bioactive endogenous jasmonate. However, JA-Ile (2) analogues trigger different responses in the plant. ω-Hydroxylation of the pentenyl side chain leads to ...
