Figure 1 a. Sucrose content in rice grains at 5d, 10d, 15d, 20d
and the mature stage after light treatment in 2018 and 2019;b.Contents of ABA in rice grains at 5d, 10d, 15d, and 20d after light
treatment in 2019.
Figure 2 a. The number of circRNAs shared between
different light treatments and different development times: all
developmental stages (purple), the treatment and control at 5 d
(orange), treatment and control at 10 d (green), three periods of
control (red), and three periods of low light (pink). b . The
sequences of all circRNAs constitute a specific source. c. The
numbers of differentially expressed circRNAs were compared in the
control at 5d and 10d, and at 5d and 10d after exposure to low light.
Figure 3 a. Networked view of the differentially
expressed circRNAs targeting miRNAs. Blue represents miRNA, green
represents circRNA that targets more than two miRNAs, and yellow
represents less than two circRNAs. b. Validation of the
differentially expressed circRNAs by real-time PCR assay. See Table 1
for the circRNA names. Means of samples denoted with the “*” are
significantly different at P < 0.05 according to the t-test
compared to the control after 5 d.

expressed circRNAs and their target genes in rice grains under weak
light.
