Methyl Jasmonate Reduces Water Stress in Strawberry

Journal of Plant Growth Regulation, 1999
The effect of methyl jasmonate (MJ) on changes of oxygen-scavenging enzyme activities and membrane lipid composition was studied in strawberry leaves under water stress. Under water stress, MJ treatment reduced the increase of peroxidase (EC 1.11.1.7; POD) activity, maintained higher catalase (EC 1.11.1.6; CAT) and superoxide dismutase (EC 1.15.1.1 ...

Optical Isomers of Methyl Jasmonate in Tea Aroma

Bioscience, Biotechnology, and Biochemistry, 1996
Two epimers of methyl jasmonate were optically resolved by capillary gas chromatography, using heptakis (2,3,6-tri-O-methyl)-β-cyclodextrin as the chiral stationary phase. In the tea volatile concentrates, both of these epimers were present as only one enantiomer, their absolute configurations being ascertained as (-)-(1R,2R)-methyl jasmonate and ...

The absolute configuration of methyl jasmonate

Tetrahedron, 1965
Abstract The absolute configuration of the jasmine oil constituent methyl jasmonate has been determined. Methyl dihydrojasmonate was synthesized from (−) 3-oxocyclopentaneacetic acid, whose configuration was established by three independent methods: (a) ORD comparison with 3-methylcyclopentanone, (b) synthesis from optically active norcamphor, and (c)

Bidirectionalization of a methyl jasmonate-inducible plant promoter

Biotechnology Letters, 2010
A unidirectional promoter can be transformed into a bidirectional module by artificial methods. Here we report the bidirectionalization of the methyl jasmonate (MeJA)-inducible PtDrl02 promoter derived from poplar [(Populus tomentosa × P. bolleana) × P. tomentosa] in planta.

Methyl jasmonate and cis‐jasmone do not dispose of the herbivore‐induced jasmonate burst in Nicotiana attenuata

Physiologia Plantarum, 2004
The oxylipin pathway mediates wound‐ and herbivore‐induced defense reactions in Nicotiana attenuata as evidenced by a transient jasmonic acid (JA)‐burst that precedes these defense responses. The fate of this induced JA‐burst remains unknown. Two derivatives of JA, its methylester, methyl jasmonate (MeJA) and cis‐jasmone (cisJ), are thought to be a ...

Methyl jasmonate as a vital substance in plants

Trends in Genetics, 2003
The plant floral scent methyl jasmonate (MeJA) has been identified as a vital cellular regulator that mediates diverse developmental processes and defense responses against biotic and abiotic stresses. The pleiotropic effects of MeJA have raised numerous questions about its regulation for biogenesis and mode of action.

ARE JASMONATES (Jasmonic acid and Methyl jasmonate) A NEW CLASS OF PLANT HORMONES

2014
Bu çalışmada, bitkisel bir hormon olduğu iddia edilen jasmontlar hakkında genel açıklamalar yapılmıştır. Son yıllarda yapılan çalışmalar sonucunda, jasmonatların, bitklerde boyuna gelişme, köklerde büyüme, doku kültüründe gelişme, embriyogenesis, tohum ve polen çimlenmesi, çiçek gözü oluşumu ve fotosentez aktivitesi üzerinde engelleyici, doku ...
