Control of tissue dimensions in multicellular organisms requires the precise quantitative regulation of mitotic activity. In plants, where cells are immobile, tissue size is achieved through control of both cell division ...

[EN] Plants orient their growth depending on directional stimuli such as light and gravity, in a process known as tropic response. Tropisms result from asymmetrical accumulation of auxin across the responding organ relative ...

[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 ...

[EN] After germination, seedlings can follow two alternative development programs, photomorphogenesis or escotomorfogénesis depending on the presence or absence of light, respectively. The transition between the two programs ...

[EN] Cell expansion is an increase in cell size and thus plays an essential role in plant growth and development. Phytohormones and the primary plant cell wall play major roles in the complex process of cell expansion. In ...

Interés del estudio: el desarrollo vascular de las plantas, y más concretamente del xilema es un proceso determinante en el correcto desarrollo de las plantas, y vital para la formación de los recursos madereros de los ...

[EN] In plants, the only confirmed function for thermospermine is regulating xylem cells maturation. However, genes putatively encoding thermospermine synthases have been identified in the genomes of both vascular and ...

[EN] DELLA proteins, which act as negative regulator in the gibberellin pathway, participate in the regulation of meristem function through their interaction with class II TCP and SAWTOOH (SAW) transcription factors

The plant hormones gibberellins (GAs) regulate multiple processes of plant development. Most of this regulation occurs at the transcriptional level, through the activity of the DELLAs, which are nuclear-localized proteins ...
