TLDR
The occurrence of numerous large plastoglobules in the galled tissues seemed to be related to oxidative stress and to the recovery of the thylakoid membrane systems, and the maintenance of the ETR(MAX) values indicated the existence of an efficient strategy to maintain similar photosynthesis rates in galled and non-galled tissues.About:

TL;DR: It is predicted that reactive oxygen species (ROS) play a role in gall induction, development and histochemical gradient formation and activity of carbohydrate-related enzymes across diverse galls corroborates this hypothesis.

TL;DR: Developmental processes and cytological events are revisited from the perspective of the redox-potential balance in both the apoplast and symplast, especially concerning the accumulation of reactive oxygen species (ROS).

Unique histochemical gradients in a photosynthesis-deficient plant gall
TL;DR: The lack of morphological continuum and physiological continuum between the extralaminar galls of N.myrtoidis and the leaves of P. myrtoides, together with the low impacting feeding activity of the sucking insect, determine the establishment of a photosynthesis-deficient structure with unique features among Neotropical galls.

The role of phenolics in the control of auxin in galls of Piptadenia gonoacantha (Mart.) MacBr (Fabaceae: Mimosoideae)
TL;DR: It is concluded that phenolics seem to act primarily as growth regulators and secondarily as a chemical defense against natural enemies in gall systems, and their involvement in growth and development of different gall morphotypes is confirmed.

THE USE OF LEAD CITRATE AT HIGH pH AS AN ELECTRON-OPAQUE STAIN IN ELECTRON MICROSCOPY
TL;DR: The stain reported here differs from previous alkaline lead stains in that the chelating agent, citrate, is in sufficient excess to sequester all lead present, and is less likely to contaminate sections.

Improvements in epoxy resin embedding methods.
TL;DR: Epoxy embedding methods of Glauert and Kushida have been modified so as to yield rapid, reproducible, and convenientembedding methods for electron microscopy.

The relationship between the quantum yield of photosynthetic electron transport and quenching of chlorophyll fluorescence
TL;DR: In this article, the quantum yield of non-cyclic electron transport was found to be directly proportional to the product of the photochemical fluorescence quenching (qQ) and the efficiency of excitation capture by open Photosystem II (PS II) reaction centres (Fv/Fm).
