Responses of specific down-regulated transcription factor (TFs) families in inferior grains of rice subjected to moderate soil drying during grain filling. (A) Venn diagram of differentially down-regulated TFs. The indica rice variety YD6 (YD) was used and plants were either well-watered controls (CK) or subjected to moderate drying (MD) of the soil. Samples were taken at 12 d after anthesis (DAA), 18 DAA, and 24 DAA. (B) Heat map of the 21 down-regulated TFs that were common to all the comparisons shown in (A). (C, D) Predicted interacting proteins of WRKY and M-type_MADS as determined using the Interactions Viewer in STRING (https://string-db.org/cgi/input.pl).
