Manipulation of phytoene levels in tomato fruit: effects on isoprenoids, plastids, and intermediary metabolism [PDF]

, 2007
In tomato (Solanum lycopersicum), phytoene synthase-1 (PSY-1) is the key biosynthetic enzyme responsible for the synthesis of fruit carotenoids. To further our understanding of carotenoid formation in tomato fruit, we characterized the effect of ...

The characterisation of phytoene synthase-1 and 2, and 1-D-deoxy-xylulose 5-phosphate synthase genes from red chilli pepper (Capsicum annuum)

, 2023
The red colouration of ripe chilli pepper fruit is due to the presence of the carotenoid capsanthin. 1-D-deoxy-xylulose 5-phosphate synthase (DXS) and phytoene synthase(s) (PSY) are influential biosynthetic steps in the carotenoid pathway.

Manipulating the Light Systemic Signal HY5 Greatly Improve Fruit Quality in Tomato

Advanced Science
Fruit ripening in tomato fruits comprises dramatic metabolic changes that are regulated by environmental factors. Light not only drives photosynthesis but also acts as a critical signal regulating plant growth, development, and the quality of produce ...

Proteomic analysis identified proteins that are differentially expressed in the flavonoid and carotenoid biosynthetic pathways of Camellia Nitidissima flowers

BMC Plant Biology
Background Camellia nitidissima Chi is a popular ornamental plant because of its golden flowers, which contain flavonoids and carotenoids. To understand the regulatory mechanism of golden color formation, the metabolites of C.

Strigolactone Levels in Dicot Roots Are Determined by an Ancestral Symbiosis-Regulated Clade of the PHYTOENE SYNTHASE Gene Family

Frontiers in Plant Science, 2018
Strigolactones (SLs) are apocarotenoid phytohormones synthesized from carotenoid precursors. They are produced most abundantly in roots for exudation into the rhizosphere to cope with mineral nutrient starvation through support of root symbionts ...

Effect of diflufenican on total carotenoid and phytoene production in carrot suspension-cultured cells

, 2019
Main Conclusion: Diflufenican increased 493-fold the level of phytoene. Diflufenican-induced inhibition of phytoene desaturase gene expression in carrot cells resulted in an increased production of phytoene. This work analyzes the effect of diflufenican,

Domates bitkisinde tuz stresine karşı karotenoid kodlayan PSY-Fiton Sentaz ( PSY-Phytoene Synthase) ve PDS-Fiton Desaturaz (PDS- Phytoene Desaturase) genlerinin ifadesi düzeylerinin belirlenmesi.

, 2019
Karotenoidler, doğal olarak var olan izoprenoidler, foto sentetik anten ve reaksiyon merkezi komplekslerinin esas bileşenlerini oluştururlar. Fotosentez sürecinde absorbsiyon, dağılıma uğrama ve ışık enerjisinin transferinde önemli bir rol oynarlar.

RT-PCR amplification and cloning of partial DNA sequence coding for oil palm (Elaeis oleifera) phytoene synthase gene [PDF]

, 2008
The potential health benefits of carotenoids as anti cancer and antioxidant agents have recently been demonstrated. Oil palm, Elaeis oleifera in particular, is known to be the richest natural source for carotene.

Effect of salt stress on expression of carotenoid pathway genes in tomato [PDF]

Journal of Stress Physiology & Biochemistry, 2011
Carotenoids, the naturally occurring isoprenoids form essential components of photosynthetic antenna and reaction centre complexes. Thus they play a significant role in absorption, dissipation and transfer of light energy for the process of ...
