“…These factors can be regarded as stress, although many of those reports did not mention that stress was responsible for fl owering. Papers that clearly mentioned that fl owering was induced by stress have appeared only recently (Hatayama and Takeno 2003 ;Martínez et al 2004 ;Kolár and Senková 2008 ) .…”

Plants have a tendency to fl ower if placed under unsuitable growth conditions. A review of the literature reporting such nonphotoperiodic fl owering indicated that most of the factors responsible for fl owering could be regarded as stress. Those stress factors include poor nutrition, high or low temperature, high-or low-intensity light, ultraviolet light, and many others. This fl owering would be called stress-induced fl owering. The plants that were induced to fl ower by stress reached anthesis, produced fertile seeds, and the progeny developed normally in Pharbitis nil and Perilla frutescens var. crispa . Grafting experiments using two varieties of P. nil revealed that a transmissible fl owering stimulus is involved in stressinduced fl owering. Salicylic acid and/or the fl owering gene FLOWERING LOCUS T may be involved in the stress-induced fl owering of P. nil , P. frutescens , Arabidopsis thaliana , and Lemna paucicostata . The stressed plants do not need to wait the arrival of a season when photoperiodic conditions are suitable for fl owering, and such precocious fl owering might assist in species preservation. Thus, stress-induced fl owering might have a biological benefi t and should be considered as important as photoperiodic fl owering and vernalization.

“…These factors include nitrogen deficiency (Tanaka et al, 1997), low-intensity light (Takimoto, 1973), drought (Monselise et al, 1981), root removal (Wada, 1974), girdling (Ebell, 1971) and mechanical stimulation (Metzger, 1995). Recent studies have shown that ultraviolet stress (Martínez et al, 2004) and nutrient stress (Kolá r and Senková , 2008) in Arabidopsis thaliana and lowintensity light stress in Perilla frutescens (Wada et al, unpublished data) also induce flowering. Thus, although the evidence for stress-induced flowering is accumulating, the regulatory mechanism is still unclear.…”

“…crispa and Lemna paucicostata (also called Lemna aequinoctialis) flowered under LD when grown under low-intensity light and poor nutrition, respectively [10,11]. The long-day plant Arabidopsis thaliana was induced to flower early under ultraviolet-C (UV-C) radiation and poor nutrition [12,13]. Similar non-photoperiodic flowering has been reported in several plant species, and a review of those reports suggested that most of the factors responsible for flowering are stresses, including high-or low-intensity light, high or low temperature, drought, poor nutrition and mechanical stimulation [2,4].…”

Many plant species are induced to flower by stress. Stress-induced flowering has been studied mostly in the short-day plant pharbitis (also called Japanese morning glory; Ipomoea nil, formerly Pharbitis nil). In this article, physiological characteristics, the regulation by salicylic acid (SA) and the expression of flowering-related genes in stress-induced flowering in pharbitis are reviewed. Pharbitis flowered under long-days in response to poor nutrition or low temperature. The pharbitis plants induced to flower by stress reached anthesis, fruited and produced fertile seeds. The progeny of the stressed plants developed normally. Grafting experiments indicated that a transmissible flowering stimulus is involved in poor nutrition stress-induced flowering. Aminooxyacetic acid (AOA), a phenylalanine ammonia-lyase (PAL) inhibitor, inhibited the stress-induced flowering, and this inhibition was overcome by SA. Stress induced PAL activity and SA biosynthesis. PnFT2, a pharbitis ortholog of the flowering gene FLOWERING LOCUS T of Arabidopsis thaliana, was expressed when the plants were induced to flower by stress. The overexpression of PnFT2 induced flowering, and PnFT2RNAi inhibited it. AOA inhibited PnFT2 expression induced by stress, and SA eliminated this inhibitory effect. SA enhanced PnFT2 expression under poor nutrition but not under non-stressful conditions. Therefore, stress may induce the production of SA and other unknown factor(s) that may work in combination to induce PnFT2 expression and flowering.
