Abstract

Carpel development and evolution are central issues for plant biology. The conservation of genetic functions conferring carpel identity has been widely studied in higher plants. However, although genetic networks directing the development of characteristic features of angiosperm carpels such as stigma and style are increasingly known in Arabidopsis thaliana, little information is available on the conservation and diversification of these networks in other species. Here, we have studied the functional conservation of NGATHA transcription factors in widely divergent species within the eudicots. We determined by in situ hybridization the expression patterns of NGATHA orthologs in Eschscholzia californica and Nicotiana benthamiana. Virus-induced gene silencing (VIGS)-mediated inactivation of NGATHA genes in both species was performed and different microscopy techniques were used for phenotypic characterization. We found the expression patterns of EcNGA and NbNGA genes during flower development to be highly similar to each other, as well as to those reported for Arabidopsis NGATHA genes. Inactivation of EcNGA and NbNGA also caused severe defects in style and stigma development in both species. These results demonstrate the widely conserved essential role of NGATHA genes in style and stigma specification and suggest that the angiosperm-specific NGATHA genes were likely recruited to direct a carpel-specific developmental program.

Impact and social visibility

From the perspective of influence or social adoption, and based on metrics associated with mentions and interactions provided by agencies specializing in calculating the so-called "Alternative or Social Metrics," we can highlight as of 2026-04-02:

  • The use, from an academic perspective evidenced by the Altmetric agency indicator referring to aggregations made by the personal bibliographic manager Mendeley, gives us a total of: 49.
  • The use of this contribution in bookmarks, code forks, additions to favorite lists for recurrent reading, as well as general views, indicates that someone is using the publication as a basis for their current work. This may be a notable indicator of future more formal and academic citations. This claim is supported by the result of the "Capture" indicator, which yields a total of: 49 (PlumX).

With a more dissemination-oriented intent and targeting more general audiences, we can observe other more global scores such as:

  • The Total Score from Altmetric: 1.
  • The number of mentions on the social network X (formerly Twitter): 2 (Altmetric).

It is essential to present evidence supporting full alignment with institutional principles and guidelines on Open Science and the Conservation and Dissemination of Intellectual Heritage. A clear example of this is:

  • The work has been submitted to a journal whose editorial policy allows open Open Access publication.
  • Assignment of a Handle/URN as an identifier within the deposit in the Institutional Repository: http://hdl.handle.net/10251/83362
