The paper develops and compares three methods to measure in situ volumes of Arabidopsis leaf plastids using microscopy techniques and mutant lines, finding average volumes of 93 µm³ for mesophyll chloroplasts and 18 µm³ for guard cell plastids.

This study shows that altering hydroxycinnamic acid content in rice cell walls increases mesophyll conductance and photosynthesis but does not improve water-use efficiency due to increased stomatal conductance.

This study examines how mesophyll conductance (gm) in C4 grasses responds to short-term CO2 changes and links this response to leaf anatomy and biochemistry.

The paper evaluates how cell wall composition and stomatal density affect oxygen isotope enrichment in leaf water by testing mutants under different light and humidity conditions.

This study shows that maize ZmAsft genes are not essential for CO2 concentration in bundle sheath cells but affect leaf water movement and cell wall properties.

The paper shows natural variation in C4 enzyme expression in Arabidopsis and demonstrates that high C4 enzyme expression is neutral in rice, supporting the role of neutral variation in C4 photosynthesis evolution.

This study identifies genetic factors influencing leaf δ13C in maize and finds no strong link between δ13C and specific leaf area or nutrient accumulation.

This study identifies heritable genetic signatures affecting water use efficiency in Setaria by analyzing plant size, water use, and their relationship under different watering conditions.
