“…We found that BR levels and BR signaling are linked to the expression of several TFs, such as the pollen development‐related TFs SlMYB26 , Sl03g059200 , Sl08g062780 and Sl12g098560 , the tapetal development and degradation‐related TF Sl04g008420 , and the three floral organ development‐related TFs Sl03g115850 , Sl06g069710 and Sl10g006880 (Figure S7). Pollen development is also reported to be regulated by several important TFs, such as TDF1 , AMS , MS1 and MS188 , which play crucial roles in tapetal development (Zhu et al , ; Ferguson et al , ; Luo et al , ). Xu et al () showed that abnormal tapetal cells of the ams mutant in Arabidopsis caused pollen sterility.…”

“…In the present study, we found that increased BR and BZR1 activity accelerated tapetal degeneration and increased pollen fertility. The timing of tapetal PCD is mainly regulated by several transcriptional regulators, such as EAT1 , TDR1 and API5 in rice, and DYT1 , TDF1 and AMS in Arabidopsis (Li et al , ; Zhang et al , ; Zhu et al , ; Xu et al , ; Li et al , ; Niu et al , ; Luo et al , ), and the downstream proteolytic enzymes, including aspartic and Cys proteases (Cui et al , ). In addition, BR and BZR1 regulated the expression of four pollen development TFs ( SlMYB26 , Sl03g059200 , Sl08g062780 and Sl12g098560 ) and also induced the expression of Sl04g008420 (Figure S7), which is the homolog of PTC1 , a TF regulating programmed tapetal development and degradation during rice anther development (Li et al , ).…”

“…The key sample pretreatment strategies applied in plant hormone analysis include homogenization, extraction and purification steps (some studies incorporate a derivatization or labeling step depending on the analytical strategies and instrumental requirements) [42,43,[46][47][48][49][50]. Sample pretreatment procedure is the major bottleneck that limits rapid separation and simultaneous analysis of multi-class plant hormones, especially at trace levels.…”

“…Given its effective mass-tocharge (m/z) separation ability, mass analyzer provides enhanced selectivity of analytes, thereby improving quantification of trace and ultra-trace plant hormones in plant. Several types of mass analyzers have been developed such as ion trap (IT) [40], quadrupole time-of-flight (Q-TOF) [41] and triple quadrupole instruments (QQQ) [42]. Mass analyzer combined with chromatography have been extensively applied in plant hormone analysis, indicating their ability of accurate quantitative analysis and efficient separation capabilities [43].…”
