Published Workflows
Objective: Identify and prioritize intervention targets for improving crop photosynthesis and crop yield.
Why it works: The review frames photosynthesis improvement as a multi-scale problem, first surveying mechanistic intervention points across the pathway and then using systems modeling or natural variation to identify key targets, before considering whole-plant outcomes such as nitrogen use efficiency and canopy photosynthesis.

Stages
- 1.Survey light harvesting and its regulation(functional_characterization)
The review begins with light harvesting and its regulation as an upstream part of the photosynthetic process to frame possible intervention points.
Selection: Identify opportunities to optimize early photosynthetic energy capture and regulation.
- 2.Examine electron transfer bottlenecks(functional_characterization)
The abstract explicitly states progression from light harvesting to the bottleneck of electron transfer.
Selection: Focus on the bottleneck of electron transfer.
- 3.Target Calvin-Benson-Bassham cycle enzymes(functional_characterization)
After discussing light reactions and electron transfer, the review turns to carbon reactions of photosynthesis.
Selection: Consider strategies targeting enzymes of the Calvin-Benson-Bassham cycle.
- 4.Explore CO2 concentration near Rubisco and CO2 delivery into leaves(functional_characterization)
The review next considers organism-inspired CO2-concentrating and delivery strategies after enzyme-targeting approaches.
Selection: Explore methods to increase CO2 concentration near Rubisco and ways to enhance CO2 delivery into leaves.
- 5.Identify key targets using systems modeling and natural variation(decision_gate)
The abstract explicitly introduces these as two approaches for identifying key targets beyond individual process descriptions.
Selection: Use systems modeling and the study of natural variation to identify key targets for photosynthesis improvement.
- 6.Holistic evaluation of selected strategies(secondary_characterization)
The review concludes by revisiting strategies to assess broader system-level consequences rather than only local biochemical effects.
Selection: Analyze impacts on nitrogen use efficiency and canopy photosynthesis.

Implementation would require plant engineering of the microcompartment and associated CO2-concentrating machinery. The supplied abstract does not enumerate the required parts.; requires engineering of a CO2-concentrating mechanism near Rubisco
The supplied evidence does not show that carboxysome engineering alone resolves all other photosynthetic bottlenecks such as light harvesting, electron transfer, or CO2 delivery into leaves.; the abstract does not specify assembly requirements or performance tradeoffs in crops
