The chloroplast rDNA has been cloned and a fine structure map has been established. The small chloroplast ribosomal subunit contains 16S RNA, while the large subunit contains the four distinct RNA species 23, 7, 5 and 3S rRNA. The location of the rRNA genes has been determined by electron ...
chloroplast matrix of the assimilating tissue.Aloin was initially stored in the aloin cells and then in bundle sheath cells because of aloin cells atrophy and aging.Moreover,the aloin content reduced gradually from top to bottom with leaf growth in the same plant.Mean while,the density of ...

The green leaves of plants are photosynthetically active organs which are able to store absorbed solar energy in reduced organic compounds. These assimilates represent the pool for both energy and compounds which have to meet the plant’s requirements fo
The term “mesophyll” refers to the tissue that lies between the top and lower epidermis. Parenchyma makes up the chloroplast-containing mesophyll, which performs photosynthesis. Vascular bundles, visible in the veins and the midrib, are part of the vascular system. The size of the veins affects...

Whereas in the RNAi plants the layer of the slender and spindle-shaped chloroplast grana and stroma were irregular and even disaggregated, but most of all, there was a great difference between the numbers and types of starch grain from the RNAi and the control leaves, furthermore numerous os...
