= Q. Gu
{c}

<Q. Gu> is the first-listed author of the 1998 study identifying the developmental role of <FRUITFULL> in <Arabidopsis thaliana>. The paper connected a disrupted <MADS-box transcription factor> <gene> with defective <cell differentiation> in <fruit> valves. Its indexed byline gives Q. Gu; an expanded given name is not established here.<The FRUITFULL MADS-box gene mediates cell differentiation during Arabidopsis fruit development by Q. Gu and others>[Development125,1509–1517; byline and Abstract]{ref}

The experiment made the mutation informative in two ways. An <enhancer trap> insertion disrupted the <gene>, while its <reporter gene> marked expression in valve tissues. In the mutant, valve <cells> failed to elongate and differentiate normally; the mature <fruit> consequently remained short and its tissues grew without normal coordination.<The FRUITFULL MADS-box gene mediates cell differentiation during Arabidopsis fruit development by Q. Gu and others>[Abstract, ful-1 insertion, GUS localization and valve phenotype]{ref}

The combination is more revealing than organ length alone: a local expression pattern and a tissue-specific defect connect a regulatory <gene> to development at the <cell> level. They support a role in the process without demonstrating that every downstream growth <gene> is a direct transcriptional target.
