Jasmonates constitute a family of lipid-derived signaling molecules that are abundant in higher plants. The biosynthetic pathway leading to plant jasmonates is initiated by 13-lipoxygenase-catalyzed oxygenation of α-linolenic acid into its 13-hydroperoxide derivative. A number of plant pathogenic fungi (e.g. Fusarium oxysporum) are also capable of producing jasmonates, however, by a yet unknown...

Diverse life forms have evolved internal clocks enabling them to monitor time and thereby anticipate the daily environmental changes caused by Earth's rotation. The plant circadian clock regulates expression of about one-third of the Arabidopsis genome, yet the physiological relevance of this regulation is not fully understood. Here we show that the circadian clock, acting with hormone signals,...

Abstract Jasmonates (JAs), such as jasmonic acid and its methyl ester, are lipid-derived compounds with signal functions in plant growth development, well responses to stress. JAs widely distributed plants natural regulators. do not work independently but a part of complex signaling network other phytohormones. They deployed induce response during wounding often used for elicitation stimulation...

Jasmonic acid (JA) is one of the most signaling phytohormones which play an essential role in plant development and response to biotic and abiotic stresses. It plays a key regulatory role in root elongation, pollen production, germination, fruit ripening, plant senescence [1]. Additionally, it activates plant defenses against pests, pathogens and abiotic stress. Jasmonic acid and its derivative...

After its first description as a fragrant constituent of the essentia1 oil of Jasminum grandiflorum (Demole et al., 1962), (-)-jasmonic acid methyl ester (methyl cis-2-(2-penten-l-yl)3-oxocyclopentenyl acetate, also known as methyl jasmonate [MeJA]), and related compounds were found to be widespread in the plant kingdom (Meyer et al., 1984). In addition, jasmonates occur in fungi and algae (for...

Jasmonates regulate plant secondary metabolism and herbivore resistance. How they influence primary metabolites and how this may affect herbivore growth and performance are not well understood. We profiled sugars and starch of jasmonate biosynthesis-deficient and jasmonate-insensitive Nicotiana attenuata plants and manipulated leaf carbohydrates through genetic engineering and in vitro compleme...
