Histone demethylases JMJ19 and JMJ20 interact with LUX2 to mediate flowering time and adaptation in soybean [CUT&Tag]

Project description:Flowering time is a critical trait to determine regional adaptation and yield of crops including soybean. Evening Complex (EC) components soybean LUX1, LUX2, and ELF3a are critical for flowering and adaptation to lower latitudes. However, the mechanisms of EC in regulating flowering time remain largely unclear in soybean. Here, we identified GmJMJ19 and GmJMJ20 gene paralogs encoding JmjC-domain containing proteins, which co-express and interact with GmLUX2. In vitro and in vivo assays demonstrate that GmJMJ19 and GmJMJ20 bind to histone, but lack histone demethylase activity. Notably, simultaneous mutation of GmJMJ19 and GmJMJ20 causes delayed flowering time. Further transcriptomic, CUT&Tag and ChIP-seq analyses show that GmJMJ19/20 and GmLUX2 primarily co-repress transcription of 168 genes, which are not associated with the alternation of examined histone methylation state. Strikingly, we identify that the direct repression of GmSVP by GmJMJ19/20-GmLUX2 module is independent of the classical EC-E1 pathway. Interestingly, haplotype analyses support the idea that GmJMJ19 might undergo selection during soybean expansion to lower latitude. In summary, our findings reveal a mechanistic insight of GmJMJ19/20-GmLUX2 into flowering time control beyond EC complex in plants and also provide resources for improving soybean adaptability through molecular breeding.

VASCULAR PLANT ONE-ZINC FINGER1 (VOZ1) and VOZ2 interact with CONSTANS in photoperiodic control of flowering

Project description:In plants, endogenous and environmental signals such as light control the timing of the transition to flowering . Two phytochrome B-interacting transcription factors, VASCULAR PLANT ONE–ZINC FINGER1 (VOZ1) and VOZ2 redundantly promote flowering in Arabidopsis thaliana. In the voz1 voz2 mutant the expression of FLOWERING LOCUS C (FLC) was up-regulated and expression of FLOWERING LOCUS T (FT) was down-regulated, which was proposed to be the cause of late flowering in voz1 voz2. However, the detailed mechanism by which the VOZ genes promote flowering is not well understood. Here, we show that neither the reduced FT-expression nor the late-flowering phenotype of voz1 voz2 is suppressed in the voz1 voz2 flc triple mutant . Genetic interaction experiments between voz1 voz2 and constans-2 (co-2) mutants reveal that the VOZs and CO work in the same genetic pathway. Using in vitro pull-down, electrophoretic mobility shift assays and bimolecular fluorescence complementation assays, we show that VOZ1 and VOZ2 interact with CO. The voz1 voz2 35S::CO:YFP plants show suppression of the early-flowering phenotype induced by CO-overexpression, showing that CO requires VOZ for induction of flowering. Determination of the VOZ consensus binding site followed by genome-wide sequence analysis failed to identify any VOZ-binding sites near known flowering-time genes. Together, these results indicate that the VOZ genes regulate flowering primarily through the photoperiod pathway, independent of FLC, and suggest that VOZs modulate CO function to promote flowering.

Transcriptome analysis of photoperiodic flowering in soybean.

Project description:In order to identify candidate genes that are involved in soybean flowering transition in response to photoperiods, we performed RNA sequencing analysis under different photoperiod treatments. We identified genes exhibiting daily oscillation patterns under different photoperiod treatments, genes under control of maturity loci (E1, E2, E3 and E5), and genes that constitute the soybean flowering gene network.
