Science 318:261–265, Sharrock RA, Clack T (2004) Heterodimerization of type II phytochromes in Arabidopsis. In rice, flowering time (or heading date) is critical for the adaptation to different cultivation areas and cropping seasons and may be affected by environmental conditions such us photoperiod, temperature, and light intensity. Plant J 22:391–399, Izawa T, Oikawa T, Sugiyama N, Tanisaka T, Yano M, Shimamoto K (2002) Phytochrome mediates the external light signal to repress FT orthologs in photoperiodic flowering of rice. 3A) are closely associated with high latitudes, whereas the cultivars carrying functional EL1/Hd16 variants are randomly distributed independently of latitude (Kwon et al., 2014). Three PRC2‐like complexes have been identified in Arabidopsis. 3A) were found in early flowering rice varieties grown in central and southern China and in varieties from the Heilongjiang Province of North-eastern China, the latter being characterized by cool summers and a short growing season (Xue et al., 2008).

To further our study of RFT1, we overexpressed the gene and examined the expression patterns of major regulatory genes during floral transition and inflorescence development. (2013). In plants, flowering time is elaborately controlled by various environment factors. This phenomenon is mediated by several independent pathways. Correspondence to - 209.59.138.227. Although PRR5 promotes flowering in Arabidopsis, transgenic rice overexpressing Arabidopsis PRR5 caused late flowering. Another mechanism for rice heat tolerance is early-morning flowering, which escapes the high temperature at midday. Plant Cell Physiol 43:1096–1105, Komiya R, Ikegami A, Tamaki S, Yokoi S, Shimamoto K (2008) Hd3a and RFT1 are essential for flowering in rice. Flowering time is a key trait for geographical and seasonal adaptation of plants and is an important consideration for rice breeders. During the vegetative growth period flowering is inhibited by several independent pathways. Active flowering generally lasts for 1–2.5 h daily during the reproductive phase, and it is very sensitive to external environmental factors such as temperature, solar radiation, etc. This might indicate that pyramiding of non-functional alleles in cultivated varieties has probably allowed further expansion of the cultivation area, and artificial construction of early flowering genotypes has been particularly successful when independent repressor pathways were targeted (Ebana et al., 2011). Thus, rice flowering occurs during summer days, which are warm but long, and varieties adapted to temperate climates show reduced sensitivity to changes in daylength, flowering under conditions normally non-inductive.

Article  The first sign that the rice plant is getting ready to enter its reproductive phase is a bulging of the leaf stem that conceals the developing panicle, called the ‘booting’ stage. Arabidopsis PSEUDORESPONSE REGULATOR7 is a signaling intermediate in phytochrome-regulated seedling deetiolation and phasing of the circadian clock. Journal of Plant Biology A Commentary on: ‘Inter- and intraspecific variation in grass phytolith shape and size: a geometric morphometrics perspective’, Gondwanan or global? There are several major genes affecting heading date that relate to vegetative growth or photoperiod sensitivity. https://doi.org/10.1007/s12374-015-0425-x. Florigen is produced in the leaves, and acts in the shoot apical meristem of buds and growing tips. Most of the upstream signals are transferred to Early heading date 1 (Ehd1) that is a positive regulator of Heading data 3a (Hd3a) and Rice FT 1 (RFT1), which are transferred to the shoot apical meristem to induce the reproductive transition. Rice ( Oryza sativa ) is a facultative short-day plant that flowers very late when grown in non-inductive long day conditions. Flowering time is a key trait for geographical and seasonal adaptation of plants and is an important consideration for rice breeders. Although several inhibitors that delay flowering have been identified, the process by which rice eventually flowers under non-permissive LD conditions is not well understood.

Development 135:767–774, Komiya R, Yokoi S, Shimamoto K (2009) A gene network for longday flowering activates RFT1 encoding a mobile flowering signal in rice. Grey arrows (represented only in A) indicate the requirement for Hd3a expression at southern latitudes and for Hd3a and RFT1 expression at higher latitudes. Repressors (or suppressors) of flowering play a crucial role in reducing florigen gene expression under LD conditions, leading to a strong delay in heading date. Published by Oxford University Press on behalf of the Annals of Botany Company. During the vegetative growth period flowering is inhibited by several independent pathways. Rice flowers after a lengthy vegetative growth. The methylation of histone H3 lysine 36 (H3K36) plays critical roles in brassinosteroid ()-related processes and is involved in controlling flowering time in rice (Oryza sativa).Although enzymes that catalyze this methylation reaction have been described, little is known about the recognition mechanisms to decipher H3K36 methylation information in rice.

However, arabidopsis is not representative of all plant species, and several examples discussed in this review indicate that several monocot-specific (or even Oryza-specific) genes do not have functional equivalents in dicots (Doi et al., 2004; Yan et al., 2004; Xue et al., 2008; Matsubara et al., 2011; Wang et al., 2013; Wu et al., 2013). Plant J 63:18–30, CAS  These alleles have been useful tools to introduce tropical varieties into temperate areas and to increase the northern limit of rice cultivation. Nat Biotechnol 28:788–797, CAS  After sufficient vegetative growth, flowering signals are produced in the leaves due to reduced expression of the inhibitors. This breaks the dormancy stage of the seed. Oxford University Press is a department of the University of Oxford. (2012), Gao et al. Recently it was found that RICE FLOWERING LOCUS T 1 (RFT1), the closest paralog of Hd3a, also functions as a mobile flowering signal that works mainly under long day conditions (LDs) (11, 12). 3A) were detected in a wide range of latitudes, including the northern limit of rice cultivation (Koo et al., 2013). RFT1 is located only 11.5 kb from Hd3a on chromosome 6. Both of the “florigen” genes are regulated by Hd1, Early heading date 1 (Ehd1), and Days to heading 2 (DTH2) (4, 7, 13). Photo about Period of flowering panicle rice. Flowering time (heading date) in rice (Oryza sativa) is an important agronomic trait that determines yield. Google Scholar, Lee YS, Lee DY, Cho LH, An G (2014) Rice miR172 induces flowering by suppressing OsIDS1 and SNB, two AP2 genes that negatively regulate expression of Ehd1 and florigens. In rice (Oryza sativa L.), there is a diversity in flowering time that is strictly genetically regulated. Day length shorter than 13.5 h will greatly induce the flowering of rice (Itoh et al., 2010). However, since florigens are highly conserved across rice varieties and species, flowering diversification has mainly resulted from the regulation of florigen expression levels that are highly correlated with flowering time. Gynheung An. From additional QTL analyses, Hd6, a minor heading date allele, was detected (Yamamoto et al., 2000).

Special attention is required for Hd1, which acts as a repressor under LDs but as an inducer under SDs. Flowering time control is critically important for the reproductive accomplishment of higher plants as floral transition can be affected by both environmental and endogenous signals. 6 °N) use both the RFT1- and Hd3a-dependent pathways to promote flowering, whereas rice varieties growing at southern latitudes mostly use the Hd3a pathway (Fig. In this study, a newly identified QTL, DTH8 (QTL for days to heading on chromosome 8), was found to regulate these three traits in rice. The mutant allele has been used in breeding programmes outside of Japan, its country of origin, and spread to Europe, where it probably conferred an agronomic advantage over functional alleles (Wei et al., 2010; Fujino et al., 2012). Rice cultivars exhibit a wide range of variation in their degree of sensitivity to photoperiod (87, 254, 319, 357, 531, 563).
