Antioxidant Defenses in Plants with Attention to Prunus and Citrus spp.

Reactive oxygen species (ROS) are by-products of oxidation/reduction reactions that can damage higher plant cells through oxidative stress. This review discusses enzymatic antioxidants, including superoxide dismutase (SOD), catalase (CAT), and ascorbate peroxidase (APX), as well as non-enzymatic defenses like ascorbic acid, glutathione, flavonoids, carotenoids, and tocopherols that protect against ROS. The study explores the role of ROS scavenging systems during seasonal changes and developmental events like fruit ripening and senescence that impact fruit quality and highlights Prunus and Citrus species due to their nutritional and antioxidant properties. These findings help to understand the importance of antioxidants in protecting plants and their potential health benefits for humans.

Marchantia polymorpha: Taxonomy, Phylogeny and Morphology of a Model System.

Marchantia polymorpha is a commonly studied plant in plant biology due to its potential as a new model system, aided by ease of genetic transformation and genome sequencing. The author provides a comprehensive review of the plant's anatomy and developmental morphology of each organ and tissue of the gametophyte and sporophyte through extensive literature review and observations. This research provides an important resource for future studies on Marchantia polymorpha.
