| TF family name | TF locus ID | Gene name | Gene description |
|---|---|---|---|
| Upregulated under low CO2 | |||
| AP2-EREBP | At1g74930 | ORA47 (Octadecanoid derivative- responsive AP2/ERF-domain transcription factor 47) | ORA47 is a regulator of jasmonate biosynthesis (Pauwels and Goossens, 2008) |
| C2C2-GATA | At4g26150 | CGA1 (CYTOKININ-RESPONSIVE GATA FACTOR1) | CGA1 was regulated by light, nitrogen, cytokinin, and gibberellic acid, and modulated nitrogen assimilation, chloroplast development, and starch production (Bi et al., 2005; Naito et al., 2007; Mara and Irish, 2008; Richter et al., 2010; Hudson et al., 2011); CGA1 play a key role in chloroplast development, growth, and divison in Arabidopsis (Chiang et al., 2012) |
| AP2-EREBP | At4g34410 | RRTF1 (redox-responsive transcription factor 1) | RTF1 is involved in redox homeostasis under high light stress (Khandelwal et al., 2008) |
| AP2-EREBP | At5g05410 | DREB2A (dehydration-responsive element-binding protein 2A) | DREB2A is involved in dehydration- responsive gene expression and overexpression of an active form of DREB2A results in significant stress tolerance to dehydration and significant growth retardation (Sakuma et al., 2006) |
| C2H2 | At5g59820 | ZAT12 | Zat12 plays a central role in reactive oxygen and abiotic stress signalling in Arabidopsis and overexpression of Zat12 in Arabidopsis results in the enhanced expression of oxidative- and light stress-response transcripts (Davletova et al., 2005) |
| Downregulated under low CO2 | |||
| C2C2-CO-like | At1g49130 | COL8 (CONSTANS-LIKE 8) | Zinc finger (B-box type) family protein |
| SBP | At2g33810 | SPL3 (SQUAMOSA PROMOTER BINDING PROTEIN-LIKE 3) | SPL3 is involved in regulation of flowering and vegetative phase change (Cardon et al., 1997; Wu and Poethig, 2006; Yamaguchi et al., 2009) |
| C2C2-CO-like | At4g27310 | BBX28 | Zinc finger (B-box type) family protein |
| G2-like | At5g44190 | GLK2 (Golden2-like 2) | GLK2 is required for normal chloroplast development (Fitter et al., 2002); GLK2 together with GLK1 optimize photosynthetic capacity by integrating responses to variable enironmental and endogenous cues (Waters et al., 2009) |
| MADS | At5g62165 | AGL42 (AGAMOUS-LIKE 42) | AGL42 is involved in the floral transition and RNAi-directed downregulation of AGL24 results in late flowering (Yu et al., 2002) |
