An Overview of Chloroplast Biogenesis and Development
During evolution plants have incorporated chloroplasts into their cells. Within the chloroplast energy is produced during photosynthesis but also...

Or mutation leads to photo-oxidative stress responses in cauliflower (Brassica oleracea) seedlings during de-etiolation
The Orange ( Or ) gene is a gene mutation that can increase carotenoid content in plant tissues normally devoid of pigments. It affects plastid...

Biogenesis and homeostasis of chloroplasts and other plastids
Chloroplasts are the organelles that define plants, and they are responsible for photosynthesis as well as numerous other functions. They are the...
-
Etioplasts and Their Significance in Chloroplast Biogenesis
Etioplasts are considered as convenient but not completely adequate laboratory models of proplastid-to-chloroplast development. These plastids are...

Margareta Ryberg (1946–2012): a personal tribute
We pay tribute to the life and work of Margareta Ryberg (1946–2012). She was an expert on the different forms of protochlorophyll(ide), their protein...

Plastoglobuli, Thylakoids, Chloroplast Structure and Development of Plastids
The overview provides basic information on the appearance and biosynthesis of thylakoids and osmiophilic plastoglobuli and their association with...

Regreening of Yellow Leaves
Yellowing of leaves is the most widely observed manifestation of senescence in plants. Various aspects of this type of programmed cell death are...

Modulation of Chlorophyll Biosynthesis by Environmental Cues
Environmental signals control diverse physiological processes in plant growth and development. Plants tend to adapt the structure of photosynthetic...

Arabidopsis light-dependent protochlorophyllide oxidoreductase A (PORA) is essential for normal plant growth and development
During skotomorphogenesis in angiosperms, NADPH:protochlorophyllide oxidoreductase (POR) forms an aggregate of photolabile...

Dominance of a 675 nm chlorophyll(ide) form upon selective 632.8 or 654 nm laser illumination after partial protochlorophyllide phototransformation
The phototransformation pathways of protochlorophyllide forms were studied in 8–14-day-old leaves of dark-germinated wheat ( Triticum aestivum L.)...

Understanding chloroplast biogenesis using second-site suppressors of immutans and var2
Chloroplast biogenesis is an essential light-dependent process involving the differentiation of photosynthetically competent chloroplasts from...

Stromule Formation
Stromules are highly dynamic stroma-filled tubules extending from the surface of plastids in all multicellular plants. Although stromules may...

Development-Dependent Changes in the Amount and Structural Organization of Plastid DNA
Plastids usually contain numerous copies of their genome. The reason of maintaining high copy numbers of the plastome and their changes resulting...
