However, little is known regarding the biological relevance of XOS to plants. Here, we found XOS triggered stomatal closure in Arabidopsis in a dose‐dependent manner. Pamarcological data showed that XOS‐induced stomatal closure was markedly inhibited b ...

Abstract:
... Chemically synthesized 2-hydroxyethyl jasmonate (HEJA) was for the first time employed to induce the ginsenoside biosynthesis and to manipulate the product heterogeneity in plant cell cultures. The dose response and timing of HEJA elicitation were investigated in cell suspension cultures of Panax notoginseng. The optimal concentration and timing of HEJA addition for both cell growth and ginsenosid ...

The transgenic rice plants accumulated about three times more JA than did the wild-type. The transgenic rice seeds required two more days to germinate, as compared to the wild-type, and shoot and root growth was inhibited. ...

In the present study, we show that 10 ppm MJA also inhibits anther extrusion in bar ...

Abstract:
... Treatment of sweet potato plants cultured in vitro with a vapor of methyl jasmonate (MeJA) induced an accumulation in leaves of a large amount of protein with an apparent molecular mass of 18 kDa. This protein, designated ipomoelin, was purified, and the amino acid sequences of proteolytic fragments were determined. Screening a cDNA library of MeJA-treated leaves by oligonucleotide probes designed ...

Abstract:
... The development of endopeptidase activity in cotyledons of Vigna mungo seedlings was examined after application of exogenous amino acids, sugars and plant hormones. The endopeptidase activity in the cotyledons fell when germinating seeds were allowed to absorb a solution of amino acids at high concentrations, and it was postulated that this effect might have been caused in part by osmotic stress a ...

Abstract:
... The effect of long-term (7 days) and short-term (up to 2 h) treatment of barley plants with jasmonic acid (JA) on the components contributing to stomatal and nonstomatal limitation of photosynthesis was studied. Net CO2 assimilation rate (A) responses to intercellular CO2 concentration (Ci), i.e., A/Ci curves, were used to assess the photosynthetic ability. Long-term treatment of barley plants wit ...

Abstract:
... Acquired disease resistance can be induced in rice (Oryza sativa) by a number of synthetic or natural compounds, but the molecular mechanisms behind the phenomenon are poorly understood. One of the synthetic inducers of resistance, 2,6-dichloroisonicotinic acid (INA), efficiently protected rice leaves from infection by the rice blast fungus Magnaporthe grisea (Hebert) Barr. A comparison of gene-ex ...

Abstract:
... The importance of the two chiral centers at C-3 and C-7 in the molecular structure of jasmonic acid in plant responses was investigated. We separated methyl jasmonate (MeJA) into (3R)- and (3S)-isomers with a fixed stereochemistry at C-3, but epimerization at C-7 is possible. The four isomers of the nonepimerizable analog 7-methyl MeJA were synthesized. These six esters and their corresponding aci ...

Abstract:
... The spatial and temporal deployment of plant defense responses involves a complex interplay of signal events, often resulting in superimposition of signaling processes. We have employed a minimal-wound protocol to clearly separate and characterize the specific contributions of light, wounding, and a wall glucan elicitor preparation (PWG) from Phytophthora sojae (Kauf. and Gerde.) to the regulation ...

Abstract:
... Stem node culture of the potato (Solanum tuberosum) cv. Sante was used to examine the phenotypical alterations due to different levels of endogenous cytokinins. The altered phenotype, which dramatically deviates from the control phenotype, was induced after treatment of plantlets with 1 micromolar jasmonic acid. Plantlets grown on the medium supplemented with jasmonic acid were taller, with well d ...

Abstract:
... The effects of methyl jasmonate (MJ) and abscisic acid (ABA) on some physiological processes of rice were compared. MJ exhibited ABA-like effects by promoting senescence of detached leaves, by inducing acid phosphatase activity of detached leaves, by inhibiting ethylene production and shoot growth of seedlings, as well as inhibiting callus formation from anthers. However, MJ and ABA had opposite e ...

Abstract:
... In the last few years, much attention has been given to the role of proteins that accumulate during water deficit. In this work, we analyzed the electrophoretic patterns of basic protein extracts, enriched for a number of cell-wall proteins, from bean (Phaseolus vulgaris L.) seedlings and 21-d-old plants subjected to water deficit. Three major basic proteins accumulated in bean seedlings exposed t ...
