Heat shock proteins and heat shock responseSOD and antioxidative responseFunctional genes and leaf morphogenesis

Laboratory Introduction

  • The induction of HSPs synthesis in response to heat stress is observed in a broad range of organisms from bacteria to humans. The universal and evolutionary conservation of HSPs has led to the view that these proteins might play an important fundamental role in high temperature survival for organisms . In response to heat shock, plants synthesize LMW HSPs, the most abundant proteins induced by heat stress, which range in mass from 15 to 30 kD. Many studies indicate that LMW HSPs act as molecular chaperones, which have the ability to interact with nonnative proteins to stabilize them in a folding-competent state ready for refolding until the ATP-dependent chaperones, restore the refolding of the thermodenatured proteins to a native physiological activity then to acquire thermotolerance. To help understanding of the physiological functions, the expression profiles, and the HS transcription factors and HS response elements of the class I LMW HSPs, under various HS temperatures, heavy metal ions, amino acid analog of rice are investigated. ​ Superoxide, a self-generated molecule during the oxidative metabolic process of cells, resulting in oxidative stress, leads to damages in proteins, lipids and DNA or cell death. Mitochondrion is the major site where 3 to 5% of oxygen was reported to convert into superoxide. Superoxide dismutase (SOD) catalyzes the conversion of superoxide into oxygen and hydrogen peroxide. Organisms have precise regulatory systems to monitor superoxide concentration for appropriate release of oxidative during stress growth and development. Research reports have also indicated that overexpression of the SOD gene in plants can provide tolerance against antioxidative stress. Bamboo shoots grow very rapidly, indicating that it might have a special and efficient antioxidant system to release the stress when the energy is generated from mitochondria during cell division and elongation. The antioxidative systems of green bamboo shoots were studied to unders tand the role of SOD in fast growing and highly oxidative environments of bamboo shoots in hope that increasing antioxidative capacity can inhibit plant senescence. Leaf is an organ with vital functions for plant growth and developmental, however, little is known about its genetic controls of morphogenesis because of the complicate combination effects of genes from photosynthesis, CO 2 fixation, phytohormones, and heteroblasty etc, make it difficult to approach by conventional studies. We establish a system by using a de novo T-DNA knock-out tagging vector, with highly convenient and efficient for mutagenesis. By screening mutants with abnormal phenotype from the T-DNA tagging pool can help us to identify the functional genes that may direct involve in the regulation of leaf morphogenesis.
