Cell Line
Concentration Treated Time Description References
Arabidopsis stomatal lineage cells 50 µM 2 hours Single-cell RNA sequencing analysis revealed that bikinin suppressed the expression of early stomatal lineage genes (e.g., POLAR, EPF2, CYCD7;1, and ERL1) while upregulating GMC/GC marker genes (e.g., SMR4, CYCA2;3, HT1, and KAT2), leading to reduced stomatal density.

Arabidopsis protoplast cells 20 μM 2 hours Inhibits OsGSK2 activity, reduces cytoplasmic accumulation of OsOFP8 PMC4917237
Arabidopsis cell suspension cultures overexpressing HA-tagged AtSKs 250 μM 30 minutes To assess the effect of bikinin on the thermal stability of 10 AtSKs, showing Tm shifts for AtSK11, AtSK12, AtSK13, BIN2/AtSK21, AtSK22, and AtSK41, but no effect on AtSK23, AtSK31, AtSK32, and AtSK42. PMC8931322
Arabidopsis cell suspension cultures 50 μM 30 minutes To examine the effect of bikinin on the thermal stability of AtSKs, finding that bikinin stabilized AtSK13 with a Tm shift of 5.94°C but had no effect on AtSK12. PMC8931322
Arabidopsis seedlings 50 μM 5 days Assess the effect of bikinin on hypocotyl elongation in Arabidopsis seedlings; bres1 and bres2 mutants showed reduced sensitivity to bikinin PMC9520590
Arabidopsis seedlings 30 μM 7 days To evaluate the effect of Bikinin on Arabidopsis seedling growth, results showed that Bikinin partially rescued the dwarf phenotype of TaSK1.2-1 and TaSK2.2-1 transgenic Arabidopsis. PMC4604091
Wheat embryos 2-30 μM 7-8 days To investigate the effect of Bikinin on wheat embryo development, results showed that Bikinin treatment impaired embryonic axis and scutellum differentiation. PMC4604091

Administration Dosage Frequency Description References
Barley Golden Promise and Haruna Nijo cultivars Foliar spray 10 µM, 50 µM, and 100 µM Single treatment, continued until the 5th leaf growth stage To investigate the effects of Bikinin on barley growth under salt stress, results showed that Bikinin treatment alleviated the long-term effects of salinity on barley growth, with more significant effects observed in the Haruna Nijo cultivar. PMC9569769
Barley Barley seedlings Hydroponic treatment 10 and 50 µM 5 days To investigate the regulatory effect of bikinin on the BR signaling pathway and its impact on barley seedling growth. Results showed that bikinin treatment reduced the phosphorylated forms of HvBZR1 and detected a tiny band of dephosphorylated form in the shoots of Haruna Nijo cultivar. PMC8706524
Arabidopsis thaliana BR biosynthesis mutant cpd and signaling mutant bri1-1 Medium treatment 30 μM 7 days Compounds 10 and 15 partially rescued the phenotype of BR mutants, including expanded leaves, increased hypocotyl lengths and light green leaves PMC4078015
Arabidopsis Transgenic Arabidopsis Medium treatment 30 μM 7-8 days To investigate the rescue effect of Bikinin on the dwarf phenotype of transgenic Arabidopsis, results showed that Bikinin partially rescued the dwarf phenotype of TaSK1.2-1 and TaSK2.2-1 transgenic Arabidopsis. PMC4604091
Arabidopsis Bin2-3 bil1 bil2 mutant Medium treatment 5 μM 10 days Bikinin significantly inhibited the activity of SnRK2.3-MYC on phosphorylating ABF fragment and reduced the phosphorylation level of T180. PMC4084465
Arabidopsis thaliana Wild-type Arabidopsis Liquid medium treatment 50 µM Single treatment, lasting 2 hours Treatment of Arabidopsis seedlings with bikinin in liquid medium significantly reduced stomatal density, primarily by decreasing the density of small non-stomatal cells and the stomatal index. Additionally, bikinin suppressed the expression of early stomatal lineage genes while upregulating GMC/GC marker genes, leading to inhibited stomatal development. PMC10483622
Arabidopsis Wild-type Arabidopsis and atskquad and atsksext mutants Treatment in liquid medium 50 μM 12 hours To investigate the effect of bikinin on PIN1 polarity and leaf venation, showing that bikinin treatment led to loss of PIN1 polarity and abnormal leaf venation. PMC8931322

Dissolving Methods
Please choose the appropriate dissolution scheme according to your animal administration guide.For the following dissolution schemes, clear stock solution should be prepared according to in vitro experiments, and then cosolvent should be added in turn:

in order to ensure the reliability of the experimental results, the clarified stock solution can be properly preserved according to the storage conditions; The working fluid for in vivo experiment is recommended to be prepared now and used on the same day;

The percentage shown in front of the following solvent refers to the volume ratio of the solvent in the final solution; If precipitation or precipitation occurs in the preparation process, it can be assisted by heating and/or ultrasound.
