“…There may be at least three reasons to explain this phenomenon: (i) Epigenetic mechanism. Previous evidence supported that the NF-Y transcription factor as important modulators of epigenetic marks controlling flowering [50][51][52][53] In summary, to elucidate the role of NF-Y transcription factor in poplar flowering induction and molecular regulation mechanism will be important for people to understand the role and function of NF-Y transcription factor family in woody plants, and provide important theoretical basis for regulating flowering time and shortening breeding cycle.…”

Background: Compared with annual herbaceous plants, woody perennials require a longer period of juvenile phase to flowering, and many traits can be only expressed in adulthood, which seriously makes the breeding efficiency of new varieties slower. For the study of poplar early flowering, the main focus is on the study Arabidopsis homologue gene CO/FT. Based on studies of Arabidopsis, rice and other plant species, some important research progress has been made on the regulation of flowering time by NF-Y subunits. However, little is known about the function of NF-Y regulating flowering in poplar. Results: In the present study, we have identified PtNF-YB family members in poplar and focus on the function of the PtNF-YB1 regulate flowering timing using transgenic Arabidopsis and tomato. To understand this mechanisms, the expression levels of three known flowering genes (CO, FT and SOC1) were examined with RT-PCR in transgenic Arabidopsis. We used the Y2H and BiFC to assay the interactions between PtNF-YB1 and PtCO (PtCO1 and PtCO2) proteins. Finally, the potential molecular mechanism model in which PtNF-YB1 play a role in regulating flowering in poplar was discussed. Conclusions: In this study, we have characterized the poplar NF-YB gene family and confirmed the function of the PtNF-YB1 regulate flowering timing. At the same time, we found that the function of PtNF-YB1 to improve early flowering can overcome species barriers. Therefore, PtNF-YB1 can be used as a potential candidate gene to improve early flowering by genetic transformation in poplar and other crops.

“…RNAi suppression of the LFY ortholog RICE FLORICAULA (RFL) strongly delays flowering (Rao et al, 2008). Wheat VRN1, a homolog of AP1, also plays a critical role in spikelet development and spike determinacy (Li et al, 2019). Expression pattern analysis showed that WFL, a LFY homolog in wheat was upregulated by VRN1 and might be associated with lateral branching of spikelets in the inflorescence meristem (Shitsukawa et al, 2006).…”

This article is protected by copyright. All rights reserved double mutants OsphyA OsphyB and OsphyA OsphyC flower much earlier than OsphyB and OsphyC single mutants in LD, indicating that OsPHYA contributes to OsPHYB and OsPHYC functions to suppress flowering under LD (Takano et al., 2005). In temperate cereals, PHYB and PHYC have different functions in flowering time from those in Arabidopsis and rice (Section III). CRY2 is the predominant photoreceptor in perception of the LD signal in the control of flowering compared to CRY1 in Arabidopsis (Liu et al., 2011). Likewise, in rice OsCRY2 is a key flowering regulator, while OsCRY1 has little effect on flowering time, suggesting functional conservation of CRYs (Hirose et al., 2006). OsFKF1 also has similar role in flowering time to its counterpart in Arabidopsis (Han et al., 2015). The function of PHOT and UVR8 homologs in rice and temperate grasses remains unknown (Dataset S2). Thus far, no studies have been carried out to investigate the functions of PHYA, CRY and FKF1 homologs in temperate grasses. Temperature sensors Few thermosensors have been identified in plants. Several proteins were reported to integrate temperature information to the clock (Gil & Park, 2019). Strikingly, the plant photoreceptor PHYB can also function as temperature receptors (Jung et al. 2016; Legris et al. 2016). The thermal reversion from active Pfr to the inactive Pr form of PHYB is rapid and can be greatly enhanced by temperature increase between 10 and 30°C. Additionally, PHYB-mediated temperature sensing and temperature-induced alterations in DNA-nucleosome dynamics are supposed to be associated with temperature-mediated entrainment of the clock (Gil & Park, 2019). PHYB function in sensing temperature has not been investigated in rice and temperate grasses. 2. Major components of the circadian clock Progress has been made in determining how the clock functions in Arabidopsis, vastly improving our understanding of its molecular architecture (Creux & Harmer, 2019; Gil & Park, 2019; Sanchez et al., 2020). Many studies show that CIRCADIAN CLOCK ASSOCIATED1 (CCA1), LATE ELONGATED HYPOCOTYL (LHY), PSEUDO-RESPONSE REGULATOR (PRR), GIGANTEA (GI), REVEILLE (RVE), NIGHT LIGHTINDUCIBLE AND CLOCK-REGULATED (LNK), EARLY FLOWERING (ELF) and LUX ARRHYTHMO (LUX) shape the core oscillator of the circadian clock including multiple transcription-translation feedback loops, thus acting as Accepted Article This article is protected by copyright.

In the outline of circadian clock, the MYB family genes CCA1 and LHY are induced in the early morning. Subsequently, a second set of MYB family genes, RVE4, RVE6 and RVE8, together with transcriptional coactivators LNK1 and LNK2, are expressed in midday. PRR family genes are also expressed after CCA1 and LHY with a sequential pattern: PRR9, PRR7, PRR5, PRR3, and PRR1 [also known as TIMING OF CAB EXPRESSION 1 (TOC1)]. Finally, a rise in m...

“…In addition, we concluded that other transcription factors identified here also play roles in the phase change, because the functions of their putative homologues in other plants have been studied. For example, plants with elevated levels of a Dof transcription factor, CYCLING DOF FACTOR 1, flower late (Imaizumi et al 2005); a member of the MYB family, ASYMMETRIC LEAVES 1, accelerates flowering by increasing the amount of gibberellin-4 and facilitating CONSTANS to induce the expression of FLOWERING LOCUS T (Song et al 2012); in barley and rice, miR171 regulation of some members of the GRAS (GAI-RGA-SCR) family mediate the phase change from vegetative to reproductive development (Curaba et al 2013;Fan et al 2015), and in rice, another member of the GRAS family, DHD1, also controls the flowering time (Zhang et al 2019). Based on the expression patterns, annotations and predicted interactions of transcription factors identified here (Table 2), and the flowering time gene network in Arabidopsis thaliana (Blümel et al 2015;Song et al 2013), we propose a regulatory network model for the phase change from vegetative to reproductive development in larch (Fig.…”

“…Genes functioning to delay reproductive growth or maintain the state of vegetative growth have been identified from herbaceous plants, such as Arabidopsis, barley, and rice, including microRNA miR156 Wu et al 2009), miR171 (Curaba et al 2013;Fan et al 2015), DHD1 (DELAYED HEADING DATE1) (Zhang et al 2019), EMF1 (Embryonic Flower 1) and EMF2 (Sung et al 2003), TEM (TEMPRANILLO) (Sgamma et al 2014), and TFL1 (Terminal Flower 1) (Mohamed et al 2010;Kotoda and Wada 2005). In gymnosperm trees, genes functioning to change the timing of reproductive growth have also been identified; among them, DAL1, a MADS-box transcription factor from Picea abies, is expressed increasingly from age 5 years, and its over-expression in Arabidopsis results in early flowering (Carlsbecker et al 2004); in contrast, the overexpression of LaAP2L1 (a heterosis-associated AP2/EREBP transcription factor from Larix) results in late flowering in Arabidopsis (Li et al 2013b) and over-expression of the PEBP genes identified in conifers also represses flowering in Arabidopsis (Karlgren et al 2011;Klintenäs et al 2012).…”

The timing of phase change from vegetative to reproductive development during aging of forest trees is important for wood and seed production. In a previous study, we investigated the effects of aging on wood formation by measuring the transcriptomic changes in the uppermost main stems of 1-, 2-, 5-, 10-, 25-, and 50-year-old Larix kaempferi. Based on the published transcriptome data, here we investigated the transcriptomic differences between the juvenile vegetative (1-and 2-year-old) and adult reproductive (25-and 50year-old) phases to determine the molecular mechanisms underlying the phase change. In total, 12,789 transcripts were identified as differentially expressed genes, including 573 transcription factors. Further analysis showed that 27 transcription factors belonging to 8 families were common to all four comparisons between old and young life stage categories: (I) 25 vs 1 year old; (II) 50 vs 1 year old; (III) 25 vs 2 years old; and (IV) 50 vs 2 years old. The analysis of their expression patterns in six age categories showed that members of the AP2 and Dof families were expressed highly in 1-and 2-year-old trees, weakly in 25-and 50-year-old trees, while members of the C3H, G2-like, GRAS, MYB-related, and MADS families had the opposite patterns. Notably, one member of the MADS family was only detected in 25-and 50-year-old trees. These results suggest that the phase change might (1) occur in the early stage of the L. kaempferi lifetime and (2) be controlled by a complex regulatory network of different transcription factors, some of which are known to play roles in the phase change in model plants. These findings not only provide molecular markers to distinguish different stages of tree growth and development and potential targets for genetic manipulation to improve the reproductive traits of trees, but also improve our understanding of the phase change with aging in trees.
