1 · What the graph read from it

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.

2 · The registry

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

Although a large number of genes encoding the WD40 motif have been identified as being involved in various developmental processes in Arabidopsis, little is known about the function of these genes in rice (Oryza sativa). Here, we report the cloning and functional characterization of a novel rice gene OsLIS-L1 (Lissencephaly type-1-like 1), which is required for normal fertility and the first internode elongation. OsLIS-L1 encodes a lissencephaly type-1-like protein containing the WD40 motif that is required for brain development in human. SMART algorithm analysis indicated that OsLIS-L1 contains a LIS1 homology (LisH) domain, a C terminus to LisH (CTLH) domain, a five WD40-repeat domain in the middle, and a domain with four WD40 repeats which is homologous to the β subunit of trimeric G-proteins (G(β)). OsLIS-L1 transcript is relatively highly abundant in stem and panicle and has a dynamic expression pattern at different panicle developmental stages. Two independent alleles, designated oslis-l1-1 and oslis-l1-2, exhibited similar abnormal developmental phenotypes, including semi-dwarf, shorter panicle length, and reduced male fertility. Cytological examination confirmed that OsLIS-L1 does not affect the meiosis in pollen mother cells. Compared with wild type, the oslis-l1 mutant had abnormal male gametophyte formation, but anther cell wall and pollen wall development were not affected. Histological analysis revealed that OsLIS-L1 regulates the cell proliferation in the first internode under the panicle. Our results indicate that OsLIS-L1 plays an important role in male gametophyte formation and the first internode elongation in rice.
