Transcription factor OsNF-YB9 regulates reproductive growth and development in rice.
Article in Planta, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 18 papers.
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
MAIN
conclusionOsNF-YB9 controls heading by affecting expression of regulators of flowering. It affects the development of the reproductive meristem by interacting with MADS1 and controlling expression of hormone-related genes. Nuclear Factor-Y (NF-Y) family of transcription factors takes part in many aspects of growth and development in eukaryotes. They have been classified into three subunit classes, namely, NF-YA, NF-YB and NF-YC. In plants, this transcription factor family is much diverged and takes part in several developmental processes and stress. We investigated NF-Y subunit genes of rice (Oryza sativa) and found OsNF-YB9 as the closest homologue of LEAFY COTYLEDON1. OsNF-YB9 delayed the heading date when ectopically expressed in rice. Expression of several heading date regulating genes such as Hd1, Ehd1, Hd3a and RFT1 were altered. OsNF-YB9 overexpression also resulted in morphological defects in the reproductive organs and led to pseudovivipary. OsNF-YB9 interacted with MADS1, a key regulator of floral development. This NF-Y subunit acted upstream to several transcription factors as well as signalling proteins involved in brassinosteroid and gibberellic acid metabolism and cell cycle. OsNF-YB9 and OsNF-YC12 interacted in planta and the latter also delayed heading in rice upon overexpression suggesting its involvement in a similar pathway. Our data provide new insights into the rice heading date pathway integrating these OsNF-Y subunit members to the network. These features can be exploited to improve vegetative growth and yield of rice plants in future.
