TLDR
The study revealed that the difference in in vitro shoot organogenesis of different chemotypes largely depends on the antioxidant protection system of the plant involving non-enzymatic compounds and activities of antioxidant enzymes.Abstract:
Withania somnifera (L.) Dunal, commonly called Indian Ginseng (Ashwagandha), is an important medicinal plant having a number of chemotypes which vary in their regenerative potentiality. In the present study, regenerative potentiality of four chemotypes of W. somnifera was compared using leaf explants. The study correlated that the chemotype (NIMTLI-130) with high total phenolic content (TPC), high H 2 O 2 concentration and low proline content was less regenerative, whereas, the chemotype (NIMTLI-101) with lesser TPC, lower H 2 O 2 concentration and high proline content was more regenerative. NIMTLI-130 showed higher SOD, GPX and APX activity compared to NIMTLI-101, but less CAT activity as well as low proline content and a weak detoxification effect resulting in lower regeneration. The study revealed that the difference in in vitro shoot organogenesis of different chemotypes largely depends on the antioxidant protection system of the plant involving non-enzymatic compounds and activities of antioxidant enzymes.read more

Catalase as a sulfide-sulfur oxido-reductase: An ancient (and modern?) regulator of reactive sulfur species (RSS)
TL;DR: Results show that catalase can act as either a sulfide oxidase or sulfur reductase and they suggest that these activities likely played a prominent role in sulfur metabolism during evolution and may continue do so in modern cells as well.

TL;DR: An efficient and improved regeneration protocol for prickly and prickleless genotypes of S. viarum has been developed and the monomorphic banding pattern of random amplified polymorphic DNA (RAPD) and simple sequence repeats (SSR) analysis confirmed the genetic fidelity of the regenerated plants.

TL;DR: In vivo redox biosensing resolves the spatiotemporal dynamics of compartmental responses to local ROS generation and provide a basis for understanding how compartment-specific redox dynamics may operate in retrograde signaling and stress 67 acclimation in plants.

TL;DR: Observations confirm that the electron donor for the scavenging of hydrogen peroxide in chloroplasts is L-ascorbate and that the L-ASCorbate is regenerated from DHA by the system: photosystem I-*ferredoxin-*NADP^>glutathione and a preliminary characterization of the chloroplast peroxidase is given.
