Plant morphogenesis. A mini review
The term Morphology, coined by Goethe (1790), refers to the oldest branch of botany, devoted to the analysis of shapes regardless of the causes which generate them.

| description | The term Morphology, coined by Goethe (1790), refers to the oldest branch of botany, devoted to the analysis of shapes regardless of the causes which generate them. Sachs (1880), following the ideas of Bacon (1561-1626), applied the law of causality to descriptive morphology, and thus, Morphogenesis was born. Phytomorphogenesis has long been part of physiology, biochemistry, biophysics, and molecular biology. It is the science that deals with the causes and the origin of shapes. In a plant, shapes develop in gradual stages of perfectly ordered structural changes, which result in organization (epigenesis). The changes in design are programmed in the genome, but their expression is controlled by precise endogenous mechanisms and environmental signals. From the phenomenological point of view, axiality, polarity, differentiation, and correlations are all operative. Physiological development is concomitant with morphogenesis, and both result in the climax process of flowering. Correlation plays a fundamental role, as each cell receives information from all parts of the organism by means of chemical (hormones, nutrients) or physical signals (light, gravity). The differentiation of a new organ or tissue implies the expression of specific genes induced by the interaction of hormones, nutrients, or physical signals. |

Goethe (1790) acuñó el término Morfología, la rama más antigua de la Botánica, que analiza las formas prescindiendo en absoluto de las causas que las generan. Sachs (1880), siguiendo la idea de Bacon (1561-1626), aplicó la ley de la causalidad a la morfología descriptiva, y así nació la Morfogénesis. La Fitomorfogénesis entró hace mucho tiempo en los dominios de la Fisiología, la Bioquímica, la Biofísica y la Biología molecular. La Fitomorfogénesis es la ciencia que trata de las causas y el origen de las formas. En un vegetal, las formas se van desenvolviendo en etapas graduales de cambios estructurales perfectamente ordenados que van organizando el ser (epigénesis). Los cambios de diseño están programados en el genoma, pero la expresión está controlada por precisos mecanismos endógenos y señales específicas del ambiente. Desde el punto de vista fenomenológico operan la axialidad, polaridad, diferenciación y las correlaciones. El desarrollo fisiológico es un proceso concomitante con la morfogénesis; ambos confluyen en la floración, fenómeno clímax tanto para uno como para el otro. La planta regula el desarrollo del programa almacenado en la cigota de manera armónica, en el tiempo justo y en el espacio adecuado.
