Fractionation of Tomato Fruit Chromoplasts
, 2019 Chromoplast differentiation involves an active synthesis of carotenoids associated with the remodeling of the preexisting plastid membrane systems to form specialized structures involved in the sequestration and storage of the synthesized carotenoids. These subplastidial structures show remarkable morphological differences and seem to be adapted to the

Artificial chromoplast biogenesis
, 2019 [EN] In the present invention, we show for the first time that the supply of phytoene to feed the carotenoid pathway functions as a primary determinant of chromoplast biogenesis in green tissues. We provide evidence that exceeding a threshold level of phytoene, the first committed intermediate of the carotenoid pathway, is sufficient to induce ...

Photosynthetic Pigments Profiled in Capsicum Lutescens Mutants
Journal of the American Society for Horticultural Science, 2021 Lutescens, or lutescent, plant mutants produce leaves that are abnormally light yellow-green compared with normal plants, and are observed in multiple species of Capsicum as well as other genera such as Zea, Oryza, and Oenothera.

Autophagy plays a dual role in chromoplast transition and degradation and is essential for fruit coloration and ripening. [PDF]
AutophagyThe color of tomato fruits is determined by carotenoids. The process involves removing chloroplast-related components and the biogenesis of chromoplast membranes where carotenoids are stored, but how these events are coordinated is unknown.

Color biogenesis data of tomatoes treated with hot-water and high temperature ethylene treatments
Data in Brief, 2021 Controlled postharvest stresses were used to induce the synthesis of carotenoids in tomato fruit. The accumulation of carotenoids was observed by the change of color of the tomato fruit from green to red.

Metabolic and molecular events occurring during chromoplast biogenesis [PDF]
, 2011 Chromoplasts are nonphotosynthetic plastids that accumulate carotenoids. They derive from other plastid forms, mostly chloroplasts. The biochemical events responsible for the interconversion of one plastid form into another are poorly documented. However,

Proteomic Analysis of Chloroplast-to-Chromoplast Transition in Tomato Reveals Metabolic Shifts Coupled with Disrupted Thylakoid Biogenesis Machinery and Elevated Energy-Production Components [PDF]
, 2012 A comparative proteomic approach was performed to identify differentially expressed proteins in plastids at three stages of tomato(Solanum lycopersicum) fruit ripening (mature-green, breaker, red). Stringent curation and processing of the data from three
