Agriculture depends on primary production by plants, so expanding our knowledge of photosynthesis is crucial if we are to meet many of the pressing global challenges faced by mankind. Terrestrial plants provide by far the most conspicuous example of oxygenic photosynthesis (referred to as photosynthesis from now on for brevity) and are responsible for about 50% of the primary production of oxygen in the biosphere, with marine production by eukaryotic algae and cyanobacteria comprising the other 50%. The most common form of photosynthesis, oxygenic photosynthesis, uses solar energy to convert the inorganic carbon dioxide (CO 2) to organic carbon, typically represented as a carbohydrate, releasing molecular oxygen (O 2) from water in the process. Photosynthesis is the biophysical and biochemical process that sustains most life on planet Earth. incana to be a valuable genomic resource for identifying ways to enhance photosynthetic rates in crop species. nigra include those involved in photosynthesis and/or abiotic stress, which may mediate the high photosynthetic efficiency of H. Genes present at copy numbers different from B. nigra 10-11 million years ago and that its genome has diversified from that of the latter two species through large chromosomal rearrangements, species-specific transposon activity, and differential retention of duplicated genes. incana and affirm its high photosynthetic efficiency relative to the Brassicaceae species Brassica rapa, Brassica nigra, and Arabidopsis thaliana. Here, we present a reference assembly of H. One such exceptional species is Hirschfeldia incana, a member of the well-studied Brassicaceae family that is easy to grow under standard laboratory conditions, providing an excellent resource for studying the genetic and physiological basis of this trait.
While the core mechanisms of photosynthesis are highly conserved, certainly in higher plants, plants that can maintain a high photosynthetic light-use efficiency at high irradiance are exceptional and may be useful to understand and improve high irradiance photosynthesis of crops.
Improving the photosynthetic capacity of agricultural crops is highly desirable to increase their yields. Photosynthesis is a biophysical and biochemical process that plays a key role in sustaining plant and human life, being the first step in the production of energy-rich molecules and oxygen in the biosphere.
