As a logical conclusion of the endosymbiotic theory , since modern day mitochondrial and chloroplast genomes do not contain a full set of housekeeping genes, and lack many that other descendants of their speculative ancestors share, there must have been a loss of genes. However, some of these genes likely migrated to the nucleus, where analogues of these genes are now found. Puzzle It is not clear why only a subset of genes have been transferred, when such gene transfer is known to be rapid on a similar timescale as mutation. Mitochondria and chloroplasts perform redox reactions, which are known to be considerably mutagenic . Such mutagenicity would encourage migration of genes away from the organelles to the nucleus. Proposed explanations Since chloroplast and mitochondrial genetic code s differ slightly from the eukaryotic nuclear code, some genes may lose function when they are transferred. References Allen, J.

Image Ti Plasmid.jpg thumb 350px right Ti plasmid with T DNA region The transferDNA abbreviated T DNA is the transferred deoxyribonucleic acid DNA of the Ti plasmid tumor inducing Ti plasmid of some species of bacteria such as Agrobacterium tumefaciens and Agrobacterium rhizogenes . It derives its name from the fact that the bacterium transfers this DNA fragment into the host plant s cell nucleus nuclear DNA genome . The T DNA is bordered by 25 base pair repeats on each end. Transfer is initiated at the left border and terminated at the right border and requires the vir genes of the Ti plasmid. The bacterial T DNA is about 20,000 base pairs long and contains gene s that code for enzyme s synthesizing opines and phytohormone s. By transferring the T DNA into the plant genome, the bacterium essentially reprograms the plant cells to grow into a tumor and produce a unique food source for the bacteria. The synthesis of the plant hormones auxin and cytokinin enables the plant cell to grow uncontrollably, thus forming the crown gall tumor s typically induced by Agrobacterium infection. The opines are amino acid derivatives used by the bacterium as a source of carbon and energy. T DNA transformation Agrobacterium mediated T DNAtransfer is widely used as a tool in biotechnology . In genetic engineering , the tumor promoting and opine synthesis genes are removed from the T DNA and replaced with a gene of interest and or a selection marker, this is required so that it is possible to establish ... of glutamine synthetase .

Unreferenced date December 2009 Chloroplast s contain several important biological membrane membranes , vital for their function. Like mitochondria , chloroplasts have a double membrane envelope, called the chloroplast envelope . Each membrane is a phospholipid bilayer , between 6 and 8 nanometre nm thick, and the two are separated by a gap of 10 20 nm, called the intermembrane space . The outer membrane is permeable to most ions and metabolite s, but the inner membrane is highly specialised with transport protein s. Carbohydrates are transported across the outer membrane by a triose phosphate translocator . The origin of chloroplasts is now largely accepted by the botany community as occurring via endosymbiosis on an ancestral basis with the engulfment of photosynthetic bacterium within the eukaryotic cell. Over millions of years the endosymbiotic cyanobacterium evolved structurally and functionally, retaining its own DNA and the ability to divide by binary fission not mitotically but giving up its autonomy by the transfer of some of its genes to the nuclear genome. Internal parts Within the inner membrane, in the region called the stroma , there is a system of interconnecting flattened membrane compartments, called the thylakoid s . These are the sites of light absorption and Adenosine triphosphate ATP synthesis, and contain many proteins, including those involved in the electron transport chain . Photosynthetic pigments such as chlorophylls a,b and c some others e.g. xanthophylls, carotenoids, phycobilins are also embedded within the granum membrane. With exception of chlorophyll a, all the other associated pigments are accessory and transfer energy to the reaction centers, Photosytems I and II.

Mitochondrial biogenesis is the process by which new mitochondria are formed in the cell. Mitochondrial biogenesis is activated by numerous different signals during times of cellular stress or in response to environmental stimuli. The mitochondrion is a key regulator of the metabolic activity of the cell, and is also an important organelle in both production and degradation of free radicals. It is thought that higher mitochodrial copy number or higher mitochondrial mass is protective for the cell. Mitochondria are produced from the transcription and translation of genes both in the nuclear genome and in the MitochondrialDNAmitochondrial genome . The majority of mitochondrial protein comes from the nuclear genome, while the mitochondrial genome encodes most parts of the electron transport chain along with mitochondrial rRNA and tRNA . The master regulators of mitochondrial biogenesis appear to be the peroxisome proliferator activated receptor gamma PGC family of transcriptional coactivators, including PPARGC1A PGC 1 , PPARGC1B PGC 1 , and the PGC related coactivator, PRC. PGC 1 , in particular, is thought to be a master regulator. It is known to co activate nuclear respiratory factor 2 GABPA NRF2 GABPA , and together with NRF 2 coactivates nuclear respiratory factor 1 NRF1 . The NRFs, in turn, activate the mitochondrial transcription factor A TFAM tfam , which is directly responsible for transcribing nuclear encoded mitochondrial proteins.

Expert subject Biology date November 2009 Mitochondrial decay is one major cause of aging , leading to the subsequent death in humans. The mitochondria are the power producing organelles found in every cell of every organ. Their primary function is to generate Adenosine triphosphate ATP through various energy cycles that involve nutrients and vitamins. ATP is needed for every movement, thought and action we make. Yet very little ATP can be stored in the body. Under normal conditions the mitochondria generate free radicals during the ATP production process and as a result subject themselves to a lot of free radical damage. As we age, the mitochondria become less efficient, fewer in number and larger. Accordingly, ATP production declines, and this may eventually lead to cell death. As organs cannot borrow energy from one another, the efficiency of each organ s mitochondria is essential to its repair processes and functions. If an organ s mitochondria fail, then so does that organ. Enhancement and protection of mitochondrial function and structure are therefore instrumental in preventing and slowing aging. Mitochondrial decay is a progressive disruption of mitochondrial structural integrity and functional ability with advancing age. It can cause impairment in cellular energy production and hence a decline in normal function, particularly in organs with high energy consumption such as the brain and the heart. Mitochondrial decay can also lead to an increase in free radical production and thus render a cell more prone to commit suicide programmed cell death or apoptosis . Some of the age related diseases, including cardiovascular and neurodegenerative disorders, have been found to involve mitochondrial dysfunction. The maintenance of a youthful mitochondrial functional ability and antioxidant capacity has become a trend in preventive health.

enzyme Name chloroplast protein transporting ATPase EC number 3.6.3.52 CAS number IUBMB EC number 3 6 3 52 GO code 0016464 image width caption In enzymology , a chloroplast protein transporting ATPase EC number 3.6.3.52 is an enzyme that catalysis catalyzes the chemical reaction ATP H sub 2 sub O math rightleftharpoons math ADP phosphate Thus, the two substrate biochemistry substrates of this enzyme are adenosine triphosphate ATP and water H sub 2 sub O , whereas its two product chemistry products are adenosine diphosphate ADP and phosphate . This enzyme belongs to the family of hydrolase s, specifically those acting on acid anhydrides to catalyse transmembrane movement of substances. The systematic name of this enzyme class is ATP phosphohydrolase chloroplast protein importing .
