“…Nevertheless, it cannot be excluded that ethylene has an influence on some other significant factor regulating flowering in this species, e.g., abscisic acid (Wilmowicz et al 2008). It was shown that auxin-induced increase in ethylene production leads, in turn, to a drop in the accumulation of abscisic acid, whose increased level in the second half of the inductive night is a factor that inhibits P. nil's transition from the vegetative development stage to generative differentiation.…”

“…The former group consists of gibberellins (Galoch et al 2002;King et al 1987;Wijayanti et al 1996), cytokinins (Friedman et al 1990;Galoch et al 1996;Halevy et al 1991) and prostaglandins (Groenewald and van der Westhuizen 2001). The latter group consists of auxins (Kulikowska-Gulewska et al 1995;Wijayanti et al 1997), ethylene (Amagasa and Suge 1987;Kęsy et al 2008), jasmonic acid (Maciejewska and Kopcewicz 2003), abscisic acid (Wijayanti et al 1997;Wilmowicz et al 2008) and brassinosteroids (Kęsy et al 2003). Among flowering inhibitors, the strongest effect is demonstrated by auxins and ethylene.…”

In this study, the first ACC oxidase (PnACO1) cDNA from model short-day plant Pharbitis nil was isolated. The expression pattern of PnACO1 was studied under different conditions (photoperiod and auxin), an adequate balance of which determines P. nil flowering. It was shown that the gene was transcribed in all the examined organs of the 5-day-old seedling and was strongly activated by auxin. Our results also revealed that PnACO1 transcript accumulation in the cotyledons showed diurnal oscillations under both LD and SD conditions. On the basis of presented and previously obtained data, we suggest that flowering inhibition evoked by IAA in P. nil results from its stimulatory effect on both ACC synthase and oxidase gene expression and, consequently, enhances ethylene production.

“…Although discoveries made in the recent years show that in photoperiod-sensitive plants the protein FT (Flowering Locus T) exerts a decisive effect on flower induction (Corbesier et al 2007;Jaeger and Wigge 2007;Mathieu et al 2007), many earlier and present studies indicate that flower induction may also be caused by phytohormones, among which the major role is played by gibberellins (Corbesier and Coupland 2005;Mutasa-Göttgens and Hedden 2009;Quesada et al 2005). In some plants, on the other hand, phytohormones-particularly auxins and ethylene-may successfully inhibit flower induction caused by photoperiod Kulikowska-Gulewska et al 1995;Ogawa and Zeevaart 1967;Suge 1972;Wilmowicz et al 2008). The same effect is caused by jasmonates, which was observed in, for example, Spirodela polyrrhiza (Krajnčič and Nemec 1995), Wolffia arrhiza (Krajnéié and Cencié 2000), Nicotiana tabacum and Chenopodium rubrum (Albrechtová and Ullmann 1994;Barendse et al 1985).…”

Independent effects of jasmonates and ethylene on inhibition of Pharbitis nil flowering

Interactions between methyl jasmonate (JA-Me) and ethylene in the photoperiodic flower induction of shortday plant Pharbitis nil were investigated. Both JA-Me and gaseous ethylene applied during the inductive long night caused a decrease in the number of flower buds generated by P. nil. Application of ethylene did not affected niether the level of endogenous jasmonates in the cotyledons during the 16 h long inductive night, nor the inhibitory effect of JA-Me on the flowering of P. nil accompanied by variations in ethylene production. The application of acetylsalicylic acid (aspirin)-a jasmonate biosynthesis inhibitor-slightly stimulated flowering. Our results have shown that the mechanisms of P. nil flower inhibition by jasmonates and ethylene are independent.

Methyl jasmonate-dependent senescence of cotyledons in Ipomoea nil

et al. 2016

View full text Add to dashboard Cite

Jasmonic acid methyl ester (JAMe) has been recently shown to play a crucial role in many physiological processes. In this paper, we focused on cotyledon senescence in Ipomoea nil and revealed that JAMe and darkness are the main factors stimulating the process examined. What is more, we showed that mefenamic acid (a jasmonate biosynthesis inhibitor) reverses the stimulatory effect of darkness on senescence. In plants growing under dark conditions, stimulation of JASMONIC ACID CAR-BOXYL METHYLTRANSFERASE (InJMT) expression and, consequently, an increase in JAMe content, have been observed. In turn, the level of jasmonic acid (JA) gradually decreased. Moreover, dark-grown seedlings demonstrated a lower PSII functional activity and a reduced chlorophyll content and autofluorescence. All of these data suggest that JAMe is a signal molecule controlling the senescence of cotyledons in I. nil.
