Manipulation of Plastidial Protein Quality Control Components as a New Strategy to Improve Carotenoid Contents in Tomato Fruit

Frontiers in Plant Science, 2019
Carotenoids such as β-carotene (pro-vitamin A) and lycopene accumulate at high levels during tomato (Solanum lycopersicum L.) fruit ripening, contributing to the characteristic color and nutritional quality of ripe tomatoes.

Assessment of Phytochemical Compounds and Antioxidant Potential of West Indian Avocado (Persea americana) Peel From Substandard‐Quality Fruits as a Valorisation Strategy

Phytochemicals in Food and Medicine, Volume 1, Issue 4, December 2026.
West Indian avocado peels discarded because of low‐commercial‐quality were evaluated as a source of bioactive compounds. Avocado peels contained high levels of phenolic compounds and showed strong antioxidant capacity. These results support avocado peel valorisation within functional foods, circular and sustainable food systems.

HY5 Positively Regulates Autophagy to Mediate Red Light‐Induced Tomato Fruit Ripening

Plant Biotechnology Journal, Volume 24, Issue 10, Page 5570-5572, October 2026.
ABSTRACT Red light accelerates tomato fruit ripening, but the molecular link between light signalling and autophagy remains unclear. Here, we show that red light promotes fruit coloration by activating autophagy in tomato pericarp. This response largely depends on the transcription factor HY5, which positively regulates this process by directly ...

Identification and Cloning of Differentially Expressed SOUL and ELIP Genes in Saffron Stigmas Using a Subtractive Hybridization Approach. [PDF]

PLoS ONE, 2016
Using a subtractive hybridization approach, differentially expressed genes involved in the light response in saffron stigmas were identified. Twenty-two differentially expressed transcript-derived fragments were cloned and sequenced.

Degradation Mechanisms, Encapsulation‐Based Stabilization, and Analytical Detection of Vitamin A

Journal of the American Oil Chemists' Society, Volume 103, Issue 9, Page 1079-1097, September 2026.
ABSTRACT Vitamin A is an important lipid‐soluble micronutrient essential for vision, immune function, and overall growth and development. However, vitamin A is unstable and susceptible to environmental factors because of its conjugated structure and inherent chemical reactivity.

Respiratory processes in non-photosynthetic plastids

Frontiers in Plant Science, 2015
Chlororespiration is a respiratory process located in chloroplast thylakoids which consists in an electron transport chain from NAD(P)H to oxygen. This respiratory chain involves the NAD(P)H dehydrogenase complex, the plastoquinone pool and the plastid ...

Lycopene‐rich food biomolecules from tomato processing waste: Green recovery, biopolymer‐based stabilisation, functional food applications and health relevance

Food Biomacromolecules, Volume 3, Issue 3, Page 646-663, September 2026.
Abstract Tomato processing waste, particularly peel and pomace, is a sustainable and low‐cost source of lycopene‐rich food biomolecules. Lycopene, a lipophilic carotenoid with an extended conjugated structure, provides intense red colour, antioxidant potential and functional value to tomato‐derived ingredients.

Overexpression of PSY1 increases fruit skin and flesh carotenoid content and reveals associated transcription factors in apple (Malus × domestica)

Frontiers in Plant Science, 2022
Knowledge of the transcriptional regulation of the carotenoid metabolic pathway is still emerging and here, we have misexpressed a key biosynthetic gene in apple to highlight potential transcriptional regulators of this pathway. We overexpressed phytoene
