... with fruit development occur at the floral meristem (FM). Age-regulated microRNA156 (miR156) and gibberellins (GAs) interact to control flowering time, but their interplay in subsequent stages of reproductive development is poorly understood. Here, in tomato ( Solanum lycopersicum ), we show that GA...

... observed in plants with reduced levels of miR156-targeted SQUAMOSA PROMOTER BINDING PROTEIN-LIKE ( SPL ) transcription factors, suggesting that AMP1 might promote SPL activity. However, we found that the amp1 mutant phenotype is only partially corrected by elevated SPL gene expression, and that amp1 has...

... ) reduce the expression of MIR156A and MIR156C , and accelerate vegetative phase change, indicating that H2A.Z promotes juvenile vegetative identity. However, arp6 and sef did not accelerate the temporal decline in miR156, and the downregulation of MIR156A and MIR156C was not accompanied by significant...

.... We demonstrate that the delay in vegetative phase change in gct and cct is largely due to overexpression of miR156, and that the delay in flowering is due in part to upregulation of FLC . Thus, GCT and CCT coordinate vegetative and floral transitions by repressing the repressors miR156 and FLC . Our...

... cues. In recent years, however, it has become evident that the genetic networks that underlie these phase transitions share some common factors. Here, we review recent advances in the field of plant phase transitions, highlighting the role of two microRNAs – miR156 and miR172 – and their respective...

...Li Yang; Susan R. Conway; R. Scott Poethig Vegetative phase change in Arabidopsis is regulated by miR156, a microRNA that promotes the expression of the juvenile phase and represses the expression of the adult phase. miR156 is expressed at a very high level early in shoot development...

... and decreased cell size in leaves. msc1 has a miR156 -resistant mutation in the SQUAMOSA PROMOTER BINDING PROTEIN-LIKE 15 ( SPL15 ) gene. msc2 and msc3 are new alleles of paused and squint mutants, respectively. All msc mutants showed accelerated heteroblasty, a phenomenon in which several morphological traits...
