BMC Plant Biology > 2019 > 19 > 1 > 1-16

Background YABBY genes play important roles in the growth and polar establishment of lateral organs such as leaves and floral organs in angiosperms. However, the functions of YABBY homologous genes are largely unknown in soybean. Results In this study, we identified GmFILa encoding a YABBY transcription factor belonging to FIL subfamily. In situ mRNA hybridization analysis indicated that GmFILa...

Boundary Formation through a Direct Threshold-Based Readout of Mobile Small RNA Gradients

Small RNAs have emerged as a new class of mobile signals. Here, we investigate their mechanism of action and show that mobile small RNAs generate sharply defined domains of target gene expression through an intrinsic and direct threshold-based readout of their mobility gradients. This readout is highly sensitive to small RNA levels at the source, allowing plasticity in the positioning of a target...

Developmental events leading to peltate leaf structure in Tropaeolum majus (Tropaeolaceae) are associated with expression domain changes of a YABBY gene

Peltate leaf architecture has evolved from conventional bifacial leaves many times in flowering plant evolution. Characteristics of peltate leaves, such as the differentiation of a cross zone and of a radially symmetric, margin-less petiole, have also been observed in mutants of genes responsible for adaxial-abaxial polarity establishment. This suggests that altered regulation of such genes provided...

Establishment of polarity in angiosperm lateral organs

John L. Bowman, Yuval Eshed, Stuart F. Baum

Trends in Genetics > 2002 > 18 > 3 > 134-141

In seed plants, lateral organs such as leaves and floral organs are formed from the flanks of apical meristems. Therefore, they have an inherent positional relationship: organ primordia have an adaxial side next to the meristem, and an abaxial one away from the meristem. Surgical and genetic studies suggest that a morphogenetic gradient, which originates in the meristem, converts the inherent polarity...
