A cellular analysis of meristem activity at the end of flowering points to cytokinin as a major regulator of proliferative arrest in Arabidopsis

MERELO CREMADES, PAZ; González-Cuadra, Irene; FERRANDIZ MAESTRE, CRISTINA (Elsevier, 2022-02-28)

[EN] In monocarpic plants, all reproductive meristem activity arrests and flower production ceases after the production of a certain number of fruits. This proliferative arrest (PA) is an evolutionary adaptation that ensures ...
ACAULIS5 Is Required for Cytokinin Accumulation and Function During Secondary Growth of Populus Trees

Milhinhos, Ana; Bollhoner, Benjamin; BLAZQUEZ RODRIGUEZ, MIGUEL ANGEL; Novak, Ondrej; Miguel, Celia M.; Tuominen, Hannele (Frontiers Media SA, 2020-11-16)

[EN] In the primary root and young hypocotyl of Arabidopsis, ACAULIS5 promotes translation of SUPPRESSOR OF ACAULIS51 (SAC51) and thereby inhibits cytokinin biosynthesis and vascular cell division. In this study, the ...
Hormonal Regulation of Ovule Initiation in Arabidopsis

Barro-Trastoy, Daniela; Gomez, Maria Dolores; Tornero Feliciano, Pablo; PEREZ AMADOR, MIGUEL ANGEL (Springer-Verlag, 2024-01-28)

[EN] As seed precursors, ovules are fundamental organs during the plant life cycle. Decades of morphological and molecular study have allowed for the elucidation of the complex and intricate genetic network regulating ovule ...
Origin & Evolution of the C3HDZ-ACL5-SACL Regulatory Module in Land Plants

Solé Gil, Anna (Universitat Politècnica de València, 2023-09-07)

[ES] El correcto desarrollo de tejidos vasculares depende del ajuste preciso entre la proliferación de células vasculares y la diferenciación celular. En Arabidopsis thaliana, la proliferación de células vasculares en el ...
Papel de las citoquininas en la regulación de las permeasas de aminoácidos de tipo AAP en respuesta a la variación en la disponibilidad de nitrógeno de tomate

Surian Marco, Lara (Universitat Politècnica de València, 2024-10-10)

[ES] Las plantas disponen de mecanismos moleculares que detectan la disponibilidad de especies de nitrógeno (N) en el suelo, y adaptan su fisiología para optimizar su crecimiento a través de procesos como la asimilación ...
The Role of Cytokinins during the Development of Strawberry Flowers and Receptacles

Pérez-Rojas, Moises; Díaz-Ramírez, David; Ortíz-Ramírez, Clara Inés; Galaz-Ávalos, Rosa M.; Loyola-Vargas, Víctor M.; FERRANDIZ MAESTRE, CRISTINA; Abraham-Juárez, Ma. del Rosario; Marsch-Martínez, Nayelli (MDPI, 2023-11)

[EN] Cytokinins play a relevant role in flower and fruit development and plant yield. Strawberry fruits have a high commercial value, although what is known as the "fruit" is not a "true" botanical fruit because it develops ...
Transcription factors HB21/40/53 trigger inflorescence arrest through abscisic acid accumulation at the end of flowering

Sánchez-Gerschon, Verónica; Martinez-Fernandez, Irene; González-Bermúdez, María R.; de la Hoz-Rodríguez, Sergio; González, Florenci V.; Lozano Juste, Jorge; Ferrándiz Maestre, Cristina; Balanzà, Vicente (American Society of Plant Biologists, 2024-05-13)

[EN] Flowers, and hence, fruits and seeds, are produced by the activity of the inflorescence meristem after the floral transition. In plants with indeterminate inflorescences, the final number of flowers produced by the ...
