Pre-Symptomatic Detection of Viral Infection in Tobacco Leaves Using PAM Fluorometry

open access: yesPlants, 2021
Chlorophyll fluorescence imaging was used to study potato virus X (PVX) infection of Nicotiana benthamiana. Infection-induced changes in chlorophyll fluorescence parameters (quantum yield of photosystem II photochemistry (ΦPSII) and non-photochemical ...

Quantitative imaging of chlorophyll fluorescence [PDF]

open access: yesNew Phytologist, 1995
summaryA computer‐controlled video system is described where images of chlorophyll fluorescence from oat (Arena saliva L.) leaves are captured throughout an induction curve. The fluorescence parameters φ11 and ΔFm/F'm which represent photosystem II photochemical efficiency and non‐photochemical quenching respectively are calculated from images taken ...

Use of a highly sensitive two-dimensional luminescence imaging system to monitor endogenous bioluminescence in plant leaves. [PDF]

open access: yes, 2004
Background All living organisms emit spontaneous low-level bioluminescence, which can be increased in response to stress. Methods for imaging this ultra-weak luminescence have previously been limited by the sensitivity of the detection systems used ...
