Correction to: PRMT6 physically associates with nuclear factor Y to regulate photoperiodic flowering in Arabidopsis

Correction to: aBIOTECH https://doi.org/10.1007/s42994-021-00065-y

In this article Figs. 2 and 3 were wrongly numbered; Fig. 2 should have been Fig. 3 and vice versa as shown below. Moreover, the Fig. 3 indications have been revised as shown: the sentence “Next, two transfer DNA (T-DNA) insertion single- mutant prmt6-1 (Sail_385_A06) and prmt6-2 (Salk_151679C) (Figs. 2A; S3a)...” has been revised as “Next, two transfer DNA (T-DNA) insertion single- mutant prmt6-1 (Sail_385_A06) and prmt6-2 (Salk_151679C) (Figs. 3A; S3a)...”; And the sentence “...was significantly more than that of nf-yc3;4;9 (Fig. 2B, D)...” has been revised as “...was significantly more than that of nf-yc3;4;9 (Fig. 3B, D)...”; And the sentence “...lower than that of the nf-yc3;4;9 triple mutant line at ZT16 under LDs (Fig. 2E)... ” has been revised as “...lower than that of the nf-yc3;4;9 triple mutant line at ZT16 under LDs (Fig. 3E)...”. The original article has been corrected.

Fig. 2

PRMT6 diurnally expressed at dusk in the vascular bundle cells under LDs. A Spatial expression patterns of PRMT6-GUS in 5-day-old seedlings, and 10-day-old seedlings of aerial part and cotyledon. Plants were stained for 6 h. Scale bars = 1 mm. B The relative transcription level of PRMT6 in 10-day-old Col seedlings under LDs. The transcription levels were normalized to UBQ10, and relative fold changes to Zeitgeber time 0 (ZT0) are presented. Bars indicate s.d. of triplicate measurements. White and dark bars below the -axis indicate light and dark periods, respectively. C, D The exprxession levels of PRMT6-FLAG protein over a 24-h LD cycle examined by western blotting. Total proteins loaded in SDS-PAGE gels were stained with Coomassie Blue, antibody or the relative PRMT6-FLAG protein levels were normalized to H3 by the ImageJ program (D). The error bars indicate the s.d. measurements

Fig. 3

Loss of PRMT6 function delays the floral transition of nf-yc3;4;9 by decreasing the FT expression under LDs. A Gene structure of PRMT6. Exons and 5’ untranslated region (UTR) or 3’ UTR are represented by black boxes and gray boxes, and arrows indicate transcription start sites (TSS); the T-DNA insertion sites of two lines are indicated with triangles. B Phenotype of Col, prmt6-1, prmt6-2, nf-yc3;4;9, and prmt6-1;nf-yc3;4;9 mutants grown in LDs. C Flowering times of the indicated genotypes grown in LDs. More than ten plants for each line were scored; bars indicated for standard deviation (s.d.); n.s. indicated non-significant difference. D Flowering times of the indicated lines grown in LDs. More than ten plants for each line were scored; bars indicated for s.d.; n.s. indicated non-significant difference; Double asterisks indicated statistically significant differences in the means between the indicated genotypes, as revealed by two-tailed Student’s t test (**p < 0.01). E Relative FT transcript levels in the seedlings of the indicated genotypes grown in LDs at ZT8 and ZT16. The transcript levels were first normalized to that of UBQ10. Bars indicate the s.d. of triplicate measurements
