Photoreceptors and Plant Responses to Light

20.3K
Light plays a significant role in regulating the growth and development of plants. In addition to providing energy for photosynthesis, light provides other important cues to regulate a range of developmental and physiological responses in plants.

Photosystems

4.8K
Photosystems are multiprotein complexes that form the functional units of photosynthesis in plants, algae, and cyanobacteria. They are found embedded in the membrane of tiny sac-like structures called thylakoids placed inside the chloroplast.
Functioning of Photosystems
Photosystems contain many pigment molecules, such as chlorophylls and carotenoids, arranged in a particular organization across two domains — the antenna complex and the reaction center. The main aim of the pigment...

Photosystem II01:22

Photosystem II

70.2K
The multi-protein complex photosystem II (PS II) harvests photons and transfers their energy through its bound pigments to its reaction center, and ultimately to photosystem I (PSI) through the electron transport chain. The pigments responsible for caputirng the light energy in photosystems include chlorophyll a, chlorophyll b, and carotenoids.
The pigment molecules are arranged across  two photosystem domains — the antenna complex and the reaction center. The main aim of the pigment...

Anatomy of Chloroplasts

108.8K
Green algae and plants, including green stems and unripe fruit, harbor chloroplasts—the vital organelles where photosynthesis takes place. In plants, the highest density of chloroplasts is found in the mesophyll cells of leaves.

The Anatomy of Chloroplasts

5.1K
Green algae and plants, including green stems and unripe fruit, harbor specialized organelles called chloroplasts to carry out photosynthesis. They coordinate both stages of photosynthesis — the light-dependent reactions and the light-independent reactions. The light-dependent reactions use sunlight to release oxygen and produce chemical energy in the form of ATP and NADPH, and the light-independent reactions capture CO2 and use ATP and NADPH to produce sugar.

What is Photosynthesis?00:39

What is Photosynthesis?

99.0K
Photosynthesis is a multipart, biochemical process that occurs in plants as well as in some bacteria. It captures carbon dioxide and solar energy to produce glucose. Glucose stores chemical energy in the form of carbohydrates. The overall biochemical formula of photosynthesis is 6 CO2 + 6 H2O + Light energy → C6H12O6 + 6 O2. Photosynthesis releases oxygen into the atmosphere and is largely responsible for maintaining the Earth’s atmospheric oxygen content.

Area of Science:

  • Plant biology
  • Developmental genetics
  • Plant physiology

Background:

  • Leaf venation patterns are critical for water and nutrient transport in plants.
  • Understanding the genetic regulation of vein development is essential for crop improvement.

Purpose of the Study:

  • To investigate the role of TOO MANY LATERALS/WIP6 (WIP6) in regulating vein specification and development.
  • To determine if WIP6 function is conserved across different photosynthetic pathways (C3 and C4).

Main Methods:

  • Utilizing genetic analysis in model grass species.
  • Employing molecular and cellular techniques to observe vein formation.

Main Results:

  • TOO MANY LATERALS/WIP6 was identified as a key regulator of lateral organ development.
  • WIP6 plays a conserved role in vein patterning in both C3 and C4 grasses.

Conclusions:

  • WIP6 is essential for proper vein specification and development in grasses.
  • The findings provide insights into the genetic control of vascular patterning in agriculturally important C3 and C4 plants.
