Cómo afectan los genes de sensibilidad al fotoperíodo PPD-1 al desarrollo del trigo a antesis?
Perez Gianmarco, Thomas; Slafer, Gustavo; Gonzalez, Fernanda Gabriela (Ediciones INTA, 2018-04)La sensibilidad al fotoperiodo afecta la adaptación del trigo al ambienteal modifiar: (i) la fecha de antesis, (ii) la duración de las etapas vegetativa y reproductiva previas a antesis, y (iii) la generación de estructuras ... -
Desarrollo de trigo en pre-antesis según la combinación alélica para los genes de sensibilidad al fotoperíodo (Ppd-1) en fotoperíodos contrastantes
Perez Gianmarco, Thomas; Slafer, Gustavo A.; Gonzalez, Fernanda Gabriela (2018-04)Adecuar la fecha de antesis (AN) al ambiente en el que crece el cultivo (adaptación) es crucial para maximizar el rendimiento alcanzable. Además, hay evidencias que sugieren que alargar la etapa en la que se diferencian ... -
Photoperiod-sensitivity genes (Ppd-1) : quantifying their effect on the photoperiod response model in wheat
Perez Gianmarco, Thomas; Severini, Alan David; Gonzalez, Fernanda Gabriela (Oxford University Press, 2019-10)Coupling anthesis date to the most suitable environmental conditions is critical for wheat (Triticum aestivum L.) adaptation and yield potential. Development to anthesis is controlled by temperature and photoperiod. Response ... -
Photoperiod-sensitivity genes shape floret development in wheat
Perez Gianmarco, Thomas; Slafer, Gustavo A.; Gonzalez, Fernanda Gabriela (2019-02)Lengthening the pre-anthesis period of stem elongation (or late-reproductive phase, LRP) through altering photoperiod sensitivity has been suggested as a potential means to increase the number of fertile florets at anthesis ... -
Wheat Ppd-1 allelic combination modulates photoperiod sensitivity
Perez Gianmarco, Thomas; Severini, Alan David; Gonzalez, Fernanda Gabriela (Sociedad Argentina de Fisiología Vegetal, 2018-11)ABSTRACT: a model linking Ppd-1 allelic composition to photoperiod response curve would allow replacing expensive and time consuming phenologic trials. In Ppd-1 near isogenic lines grown under different photoperiods we ... -
Wheat pre-anthesis development as affected by photoperiod sensitivity genes (Ppd-1) under contrasting photoperiods
Perez Gianmarco, Thomas; Slafer, Gustavo A.; Gonzalez, Fernanda Gabriela (2018-01)Fine tuning wheat phenology is of paramount importance for adaptation. A better understanding of how genetic constitution modulates the developmental responses during pre-anthesis phases would help to maintain or even ...
