thaliana leaves and sepals, FIL and YAB3 genes are upregulated by KAN1 and ARF4
, and, in turn, FIL and YAB3 stimulate the expression of ARF4
, KAN1, and AS1 [92, 94, 95], and besides, in complex with LUG and SEU promote not only organ polarity, but embryonic shoot apical meristem initiation and maintenance .

genes," Proceedings of the National Academy of Sciences of the United States of America, vol.
However, a vast majority of higher plant ARF3 and ARF4
mRNAs possessed dual complementary sites to TAS3-derived ta-siRNAs, whereas the P.
Trans-acting siRNA-mediated repression of ETTIN and ARF4
regulates heteroblasty in Arabidopsis.
It is interesting to note that a significant proportion of patients had a surgical procedure precipitating ARF4
. Contributory factors include preoperative intravascular volume depletion, anesthesia-induced hemodynamic changes, and intra operative fluid losses5.
