| Hotspot | Hotspot identified with traits | Bol name in JZS v2/v1 | Other names | Tair or others description |
|---|---|---|---|---|
| 1 | Leaf length (HS) | BolC01g004800.2J Bol013627 | CER9 and SUD1 | Encodes a protein involved in cuticular wax biosynthesis. Lines carrying a recessive mutation in this locus show downward cupped leaves |

BolC02g001500.2J Bol005467 | LMI1 | Encodes a homeodomain leucine zipper class I meristem identity regulator. Acts together with LFY to induce CAL expression. Has a role in leaf morphogenesis |
| 10 | Leaf ratio (RS and HS) | BolC02g009950.2J Bol001232 | OFP8 | Regulates cell elongation by suppressing the expression of Gibberellin 20 oxidase 1 |
| 11 |
Leaf length (HS) Leaf ratio (RS and HS) Head ratio |
BolC02g037390.2J | WDS1 | Its expression is induced by IAA, ABA, and ethylene |

| BolC03g043610.2J Bol025740 | CTL02 and TEAR2 | Ligase protein that positively regulates CIN-like TCP activity to promote leaf development | ||
| 26 |
Leaf area (RS and HS) Leaf length (HS) Leaf width (RS and HS) |
BolC05g007470.2J Bol036810 | HYL1 | Encodes a nuclear dsRNA binding protein involved in mRNA maturation. Mutant show hyponastic leaves and less sensitivity to auxin and cytokinin |
| 42 |
Leaf length (HS) Head height |
BolC08g038570.2J Bol044169 | AMP1, COP2, HPT, MFO1, and PT | Encodes glutamate carboxypeptidase. Various alleles show an increased rate of leaf initiation and cytokinin biosynthesis |
| 44 | Leaf ratio (RS and HS) | BolC09g002000.2J Bol006070 | AXR6, CUL1, ETA1, and ICU13 | Encodes a cullin that is a component of SCF ubiquitin ligase complexes involved in mediating responses to auxin and jasmonic acid |
