Barren inflorescence1 functions in organogenesis during vegetative and inflorescence development in maize.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Maize (Zea mays) has a highly branched inflorescence due to the production of different types of axillary meristems. Characterization of the barren inflorescence class of mutants has led to the discovery of genes required for axillary meristem initiation in the inflorescence. Previous studies showed that barren inflorescence2 (bif2) encodes a serine/threonine protein kinase that regulates auxin transport, and barren stalk1 (ba1) encodes a basic helix-loop-helix transcription factor that acts downstream of auxin transport. Here, we characterize Barren inflorescence1 (Bif1), a classical semidominant mutation of maize. Developmental, histological, and genetic analyses show that Bif1 mutants are defective in the initiation of all axillary meristems in the inflorescence. Real time RT-PCR experiments show that both bif2 and ba1 are expressed at lower levels in Bif1 mutants. Double-mutant analyses demonstrate that Bif1 exhibits an epistatic interaction with ba1 and a synergistic interaction with bif2. The dramatic phenotypic enhancement observed in Bif1; bif2 double mutants implies that bif1 plays an overlapping role with bif2 in the initiation of lateral organs during vegetative development. The phenotypic resemblance of Bif1 to bif2 mutants and the reduction of auxin transport in Bif1 mutants suggest that bif1 functions as a regulator of auxin transport in maize.
