COP1 is a highly conserved E3 ubiquitin ligase found across diverse eukaryotic organisms. Its conserved domains support ubiquitination, substrate recognition, protein turnover, and regulation of developmental and cellular signaling pathways.

Chromophores are light-absorbing molecular components that initiate photoreceptor activation. Explore their chemistry, spectral properties, photochemistry, and roles in phytochromes, cryptochromes, phototropins, UVR8, and animal opsins.

Photoreceptors are specialized molecular sensors that detect light and initiate signaling pathways controlling gene expression, development, metabolism, circadian rhythms, and environmental adaptation.

Light signaling is a complex biological system through which organisms detect different wavelengths of light and convert environmental information into changes in gene expression, development, metabolism, and physiology.

Auxin helps maintain root stem cells and organize the root stem-cell niche through spatial hormone gradients, PIN-mediated transport, TIR1/AFB signaling, WOX5, PLETHORA proteins, and hormone crosstalk.

Auxin is a central regulator of root meristem development, controlling stem-cell maintenance, cell division, differentiation, root growth, and root architecture through coordinated transport, signaling, and hormone interactions.

Auxin is a central regulator of lateral root formation. Discover how auxin transport, PIN proteins, pericycle cells, TIR1/AFB receptors, AUX/IAA proteins, ARF transcription factors, and hormone crosstalk control root branching and development.

Auxin is a central regulator of root development, controlling root growth, meristem activity, lateral root formation, gravitropism, root architecture, and responses to environmental conditions through coordinated transport and signaling.

ARF transcription factors translate auxin signals into changes in gene expression. Discover how ARFs interact with AUX/IAA proteins and regulate roots, shoots, organ formation, phototropism, branching, and plant development.

AUX/IAA proteins are key transcriptional repressors in the auxin signaling pathway. Discover how TIR1 and AFB receptors promote AUX/IAA degradation, release ARF transcription factors, and regulate gene expression involved in roots, shoots, organ formation, phototropism, and plant development.

Auxin receptors allow plant cells to perceive the growth hormone auxin and translate hormone levels into developmental responses. Discover how TIR1 and AFB proteins, SCF ubiquitin ligases, AUX/IAA degradation, and ARF transcription factors regulate plant growth, root development, phototropism, organ formation, and environmental responses.

Auxin signaling allows plant cells to translate hormone concentration into changes in gene expression, growth, and development. Discover how TIR1/AFB receptors, AUX/IAA proteins, ARF transcription factors, and hormone crosstalk regulate roots, shoots, phototropism, organ formation, and plant architecture.

Auxin transport allows plants to control where growth occurs by establishing directional hormone flows through their tissues. Discover how PIN proteins, auxin gradients, and polar auxin transport regulate root development, shoot growth, organ formation, branching, phototropism, and plant architecture.

Auxin and phototropism are closely connected processes that allow plants to adjust their growth direction in response to directional light. Discover how phototropins, auxin transport, asymmetric auxin distribution, and differential cell expansion work together to control plant bending and directional growth.

Phototropism allows plants to adjust their growth direction in response to directional light. Discover how phototropins detect blue light and regulate auxin distribution, differential cell expansion, and plant growth toward or away from light.
