Gene : KNAT1 A. thaliana

Gene ID  ? AT4G08150
Brief Description  homeobox knotted-like protein  Source: Araport11 (06/2016).
Is Obsolete?  false
Computational Description  ? KNOTTED-like from Arabidopsis thaliana (KNAT1); CONTAINS InterPro DOMAIN/s: KNOX2 (InterPro:IPR005541), ELK (InterPro:IPR005539), Homeobox (InterPro:IPR001356), Homeobox, conserved site (InterPro:IPR017970), KNOX1 (InterPro:IPR005540), Homeodomain-like (InterPro:IPR009057), Homeodomain-related (InterPro:IPR012287); BEST Arabidopsis thaliana protein match is: KNOX/ELK homeobox transcription factor (TAIR:AT1G62360.1).  Source: TAIR, Jun 30, 2015.
Curator Summary  ? A member of class I knotted1-like homeobox gene family (together with KNAT2). Similar to the knotted1 (kn1) homeobox gene of maize. Normally expressed in the peripheral and rib zone of shoot apical meristem but not in the leaf primordia. It is also expressed in the fourth floral whorl, in the region that would become style, particularly in the cell surrounding the transmitting tissue. No expression was detected in the first three floral whorls. Expression is repressed by auxin and AS1 which results in the promotion of leaf fate.  Source: TAIR, Jun 30, 2015.

Heterodimers with PENNYWISE or POUND-FOOLISH are essential for establishing early internode patterning events. 16741748
data showed that BP and PNY restrict KNAT6 and KNAT2 expression to promote correct inflorescence development 18390591
Expression of KNAT1 in the integuments leads to extra cell divisions in the outer layer of the outer integument, and being compensated for by a decrease of cell volume, thus showing that mechanisms exist to control proper ovule integument morphogenesis. 18410683
Results suggested that the late-flowering phenotype of the as1-1 and as2-1 mutants might have been caused by the ectopic expression of KNAT126 triple mutation. 19891706
Results indicate that BP/KNAT1 acts as a negative regulator and KNAT2 and KNAT6 act as positive regulators of floral organ separation in the IDA-HAE/HSL2 signaling cascade. 21742991
The data indicate that the ATH1-KNAT2 complex acts redundantly with KNAT6, both of which are negatively regulated by BP during pedicel development. 22140242
Arabidopsis ASYMMETRIC LEAVES complex physically interacts with PRC2 and recruits this complex to the homeobox genes BREVIPEDICELLUS and KNAT2 to stably silence these stem cell regulators in differentiating leaves. [BP] 23468429
This function of STM in meristem establishment and organisation can be replaced by KNAT1/BP, but not KNAT2. 23573875
KNAT1 negatively modulates root skewing, possibly by regulating auxin transport 23889705
NTT loss of function leads to reduced replum width and cell number, whereas increased expression promotes replum enlargement. NTT activates the homeobox gene BP, which, together with RPL, is important for replum development. 25039392
In the cambium, KNAT1 and STM, contrary to their function in the shoot apical meristem, promote cell differentiation through repression of BOP genes. 25371365
Arabidopsis plants harboring loss-of-function KNOX2 alleles exhibit impaired differentiation of all aerial organs and have highly complex leaves, phenocopying gain-of-function KNOX1 alleles. 25671434
our results indicate that BP interacts with the chromatin remodeling factor BRM to regulate the expression of KNAT2 and KNAT6 in control of inflorescence architecture. 25822547
