Other claims from this paper (10)
- Intervention effect Empty viral vector inoculation lowered net photosynthesis and transpiration from 2 to 3 days post infiltration.
- Intervention effect HA expression with the vector lowered photosynthesis and transpiration further until day 4.
- Intervention effect Leaves receiving Agrobacterium without vector or no infiltration did not show those significant gas exchange decreases.
- Mechanism The authors attribute reduced gas exchange partly to stomatal closure.
- Observation HA vector inoculation downregulated CO2 assimilation and photosynthetic electron transport capacities.
- Mechanism Those capacity reductions also contributed to lower net photosynthesis.
- Association Viral vector inoculation raised leaf temperature, associated with lower transpiration.
- Association Higher post infiltration air temperature led to earlier HA accumulation and shorter time to peak leaf HA.
- Observation Peak leaf temperature preceded peak leaf HA content by 1–2 days at all tested air temperatures.
- Recommendation The authors propose leaf temperature timing as a nondestructive guide to optimal harvest date.
