photomorphogenesis

The light-mediated changes in plant growth and development are called photomorphogenesis.

This hypothesis is also supported by the findings about other negative regulators of plant photomorphogenesis.

This is also referred to as photomorphogenesis.

Upon breaking the surface and reaching the light, the seedling's developmental program is switched to photomorphogenesis.

The photomorphogenesis of plants is often studied by using tightly-frequency-controlled light sources to grow the plants.

In developmental biology, photomorphogenesis is light-mediated development.

The developmental changes characteristic of photomorphogenesis shown by de-etiolated seedlings, are induced by light.

Her research interests are basic and applied aspects of the effects of light on plant development (photoperiodism, phytochrome, photomorphogenesis).

The field includes the study of photosynthesis, photomorphogenesis, visual system, circadian rhythms, bioluminescence, and ultraviolet radiation effects.

Phytochrome: in plants, red and far-red light reception In plant seeds, the photoreceptor phytochrome is responsible for the process termed photomorphogenesis.

Mutations in these photo receptors and their signal transduction components lead to seedling development that is at odds with light conditions, for example seedlings that show photomorphogenesis when grown in the dark.

His recent research used a flexible confocal fluorescence ratio aiming assembly to image calcium redistribution during contact sensing, stomatal aperture control, pollen tube and rhizoid growth, moss development and photomorphogenesis.

The use of light to control structural development is called photomorphogenesis, and is dependent upon the presence of specialized photoreceptors, which are chemical pigments capable of absorbing specific wavelengths of light.

Phytochrome can be used to measure the ratio of far red to red light, and thus to detect whether the plant is in the shade of another plant, so it can alter its growth strategy accordingly (photomorphogenesis).

It is implicated in regulating such diverse and fundamental cellular process as cytoplasmic streaming, thigmotropism, gravitropism, cell division, cell elongation, cell differentiation, cell polarity, photomorphogenesis and plant defense and stress responses [ 1, 3, 4].

Fundamental processes such as photosynthesis, respiration, plant nutrition, plant hormone functions, tropisms, nastic movements, photoperiodism, photomorphogenesis, circadian rhythms, environmental stress physiology, seed germination, dormancy and stomata function and transpiration, both parts of plant water relations, are studied by plant physiologists.
