Words that I was Not Familiar With
Signal transduction- this alludes to the process by which a particular cell responds to substances outside the cell via signaling molecules found on the surface and inside the cell. The process of signal transduction is crucial for cells to grow and work in a normal way.

Hexokinase- these are intracellular enzymes that phosphorate glucose, mannose, as well as fructose to the equivalent hexose 6-phosphates.
Trehalose- this is a sugar that consists of two molecules of glucose. It is also alluded to as tremalose or mycose,
Circadian clock- these are subsets of biological rhythms with a period, and it is the time to complete one cycle. The circadian clock controls several biological processes throughout the life cycle of plants.
Photosynthetic acclimation- this alludes to the change in leaves' photosynthetic efficiency because of long-term exposure to increased levels of carbon dioxide.
Morphogen- this is a substance whose non-uniform distribution controls the tissue development patterns in the morphogenesis process.
Hypocotyl- this is the segment of the stem of a plant embryo that is found under the stalks of the seed leaves and immediately above the root.
Phenotypes- this alludes to the individual traits of the plants, such as color, height, etc.
Arabidopsis- this is a plant genus that is the family of Brassicaceae. They are small flowering plants that are related to mustard and cabbage.
Allelic- these are alternative forms of a particular gene or other DNA sequences that are homologous. It is also called an allelomorph.
Three Key Take-away Points from the Article
PPs and PKs such as PP1, calcium-dependent protein kinase, SnRK, second messenger Ca2+, and mitogen-activated protein kinase are essential in plant sugar signaling.
The complete signaling circuitry cannot be entirely ascertained because of the intrinsic complexity of multicellular photosynthetic organisms with source and sink tissues as well as sugar-consuming and producing processes.
Different species have different source-link relations as well as nutrient uptake, transportation, and consumption processes.
