“…Other physiological functions related to the JA are stimulation of germination in dormant seeds ( Creelman and Mullet, 1997 ), accumulation of storage proteins ( Pelacho and Mingo-Castel, 1991 ), chlorosis ( Creelman and Mullet, 1997 ), upregulation of antioxidant enzymes ( Soares et al, 2010 ), senescence ( Seltmann et al, 2010 ), floral nectar synthesis ( Radhika et al, 2010a , b ), herbivory and wounding ( Chung et al, 2008 ; Howe and Jander, 2008 ; Ballare, 2011 ; Erb et al, 2012 ), seed and flower development ( Wasternack et al, 2012 ), systemic resistance ( Pieterse et al, 2002 , 2012 ), elicitors of plant secondary metabolism ( De Geyter et al, 2012 ), and allelopathy ( Baldwin, 2010 ), etc. Its role in gene expression has been reported in different plants such as grapevines ( Marchive et al, 2013 ), Arabidopsis ( Sasaki et al, 2001 ), tomato ( Boter et al, 2004 ), rice ( Schweizer et al, 1997 ; Liu et al, 2012 ), sugarcane ( De Rosa et al, 2005 ), etc., which leads to defense against environmental stresses ( Gfeller et al, 2010b ; Ballare, 2011 ; Sua et al, 2011 ).…”

Jasmonates (JAs) [Jasmonic acid (JA) and methyl jasmonates (MeJAs)] are known to take part in various physiological processes. Exogenous application of JAs so far tested on different plants under abiotic stresses particularly salinity, drought, and temperature (low/high) conditions have proved effective in improving plant stress tolerance. However, its extent of effectiveness entirely depends on the type of plant species tested or its concentration. The effects of introgression or silencing of different JA- and Me-JA-related genes have been summarized in this review, which have shown a substantial role in improving crop yield and quality in different plants under stress or non-stress conditions. Regulation of JAs synthesis is impaired in stressed as well as unstressed plant cells/tissues, which is believed to be associated with a variety of metabolic events including signal transduction. Although, mitogen activated protein kinases (MAPKs) are important components of JA signaling and biosynthesis pathways, nitric oxide, ROS, calcium, ABA, ethylene, and salicylic acid are also important mediators of plant growth and development during JA signal transduction and synthesis. The exploration of other signaling molecules can be beneficial to examine the details of underlying molecular mechanisms of JA signal transduction. Much work is to be done in near future to find the proper answers of the questions like action of JA related metabolites, and identification of universal JA receptors etc. Complete signaling pathways involving MAPKs, CDPK, TGA, SIPK, WIPK, and WRKY transcription factors are yet to be investigated to understand the complete mechanism of action of JAs.

“…JA induces the expression of genes encoding proteinase inhibitors (PIN), which are involved in the protection of plants from insect damage [33]. cDNA macro-array analysis revealed that MeJA treatment induced expression of several genes involved in JA biosynthesis, oxidative burst, stress-related and programmed cell death [34-40]. While defensive-associated signal has been extensively studied in angiosperms [41-43], it is a little-known in conifers.…”

De novo characterization of Larix gmelinii (Rupr.) Rupr. transcriptome and analysis of its gene expression induced by jasmonates

BackgroundLarix gmelinii is a dominant tree species in China’s boreal forests and plays an important role in the coniferous ecosystem. It is also one of the most economically important tree species in the Chinese timber industry due to excellent water resistance and anti-corrosion of its wood products. Unfortunately, in Northeast China, L. gmelinii often suffers from serious attacks by diseases and insects. The application of exogenous volatile semiochemicals may induce and enhance its resistance against insect or disease attacks; however, little is known regarding the genes and molecular mechanisms related to induced resistance.ResultsWe performed de novo sequencing and assembly of the L. gmelinii transcriptome using a short read sequencing technology (Illumina). Chemical defenses of L. gmelinii seedlings were induced with jasmonic acid (JA) or methyl jasmonate (MeJA) for 6 hours. Transcriptomes were compared between seedlings induced by JA, MeJA and untreated controls using a tag-based digital gene expression profiling system. In a single run, 25,977,782 short reads were produced and 51,157 unigenes were obtained with a mean length of 517 nt. We sequenced 3 digital gene expression libraries and generated between 3.5 and 5.9 million raw tags, and obtained 52,040 reliable reference genes after removing redundancy. The expression of disease/insect-resistance genes (e.g., phenylalanine ammonialyase, coumarate 3-hydroxylase, lipoxygenase, allene oxide synthase and allene oxide cyclase) was up-regulated. The expression profiles of some abundant genes under different elicitor treatment were studied by using real-time qRT-PCR.The results showed that the expression levels of disease/insect-resistance genes in the seedling samples induced by JA and MeJA were higher than those in the control group. The seedlings induced with MeJA elicited the strongest increases in disease/insect-resistance genes.ConclusionsBoth JA and MeJA induced seedlings of L. gmelinii showed significantly increased expression of disease/insect-resistance genes. MeJA seemed to have a stronger induction effect than JA on expression of disease/insect-resistance related genes. This study provides sequence resources for L. gmelinii research and will help us to better understand the functions of disease/insect-resistance genes and the molecular mechanisms of secondary metabolisms in L. gmelinii.

“…De Rosa et al (2005) detected a sugarcane vacuolar glycoprotein acid phosphatase VSP gene that was upregulated by MeJA application to leaves, suggesting a possible sugarcane defense mechanism against insect herbivory. The VSP upregulation was primarily in the roots, supporting the idea of movement and sequestration of nitrogen as a tolerance response during an aboveground insect attack.…”

Identification of methyl jasmonate-responsive genes in sugarcane using cDNA arrays

Abstract: Background: Ceramide is important in many cell responses, such as proliferation, differentiation, growth arrest and apoptosis. Elevated ceramide levels have been shown to induce apoptosis in primary neuronal cultures and neuronally differentiated PC12 cells.
