“…Jasmonate was shown to either promote or delay flowering depending on its concentration and on the plant species (Krajnčič et al , 2006; Wasternack, 2007). The high concentration of MeJA in mvp -mutant plants suggested a possible role associated with flowering.…”

“…JA, a fatty acid-derived compound, is associated with plant defense responses against pathogens [ 253 ]. However, JA has also been proposed to participate in flowering time regulation in several plant species [ 254 , 255 ]. The JASMONATE-ZIM domain (JAZ) family of transcriptional repressors, which are essential for JA signaling, are targeted by the F-box protein CORONATINE-INSENSITIVE PROTEIN 1 (COI1) for degradation [ 256 , 257 ].…”

In plants, environmental conditions such as temperature affect survival, growth, and fitness, particularly during key stages such as seedling growth and reproduction. To survive and thrive in changing conditions, plants have evolved adaptive responses that tightly regulate developmental processes such as hypocotyl elongation and flowering time in response to environmental temperature changes. Increases in temperature, coupled with increasing fluctuations in local climate and weather, severely affect our agricultural systems; therefore, understanding the mechanisms by which plants perceive and respond to temperature is critical for agricultural sustainability. In this review, we summarize recent findings on the molecular mechanisms of ambient temperature perception as well as possible temperature sensing components in plants. Based on recent publications, we highlight several temperature response mechanisms, including the deposition and eviction of histone variants, DNA methylation, alternative splicing, protein degradation, and protein localization. We discuss roles of each proposed temperature-sensing mechanism that affects plant development, with an emphasis on flowering time. Studies of plant ambient temperature responses are advancing rapidly, and this review provides insights for future research aimed at understanding the mechanisms of temperature perception and responses in plants.

“…Although JA has been implicated in regulating flowering time in several plant species (Krajncic et al, 2006;Robson et al, 2010), the exact role of JA in regulating this important physiological process and the underlying molecular mechanism remains obscure. Here, we report that the COI1-dependent signaling pathway delays flowering of Arabidopsis by repressing the transcriptional expression of FT. We discovered that the APETALA2 (AP2) family TFs TARGET OF EAT1 (TOE1) and TOE2 interact with a subset of JAZ proteins and repress the transcription of FT. Our study uncovers the transcriptional mechanism of JA in regulating flowering time and highlights how the specificity of JA responses is determined.…”

Flowering time of plants must be tightly regulated to maximize reproductive success. Plants have evolved sophisticated signaling network to coordinate the timing of flowering in response to their ever-changing environmental conditions. Besides being a key immune signal, the lipid-derived plant hormone jasmonate (JA) also regulates a wide range of developmental processes including flowering time. Here, we report that the CORONATINE INSENSITIVE1 (COI1)-dependent signaling pathway delays the flowering time of Arabidopsis thaliana by inhibiting the expression of the florigen gene FLOWERING LOCUS T (FT). We provide genetic and biochemical evidence that the APETALA2 transcription factors (TFs) TARGET OF EAT1 (TOE1) and TOE2 interact with a subset of JAZ (jasmonate-ZIM domain) proteins and repress the transcription of FT. Our results support a scenario that, when plants encounter stress conditions, bioactive JA promotes COI1-dependent degradation of JAZs. Degradation of the JAZ repressors liberates the transcriptional function of the TOEs to repress the expression of FT and thereby triggers the signaling cascades to delay flowering. Our study identified interacting pairs of TF and JAZ transcriptional regulators that underlie JA-mediated regulation of flowering, suggesting that JA signals are converted into specific context-dependent responses by matching pairs of TF and JAZ proteins.
