With the global climate anomalies and destruction of ecological balance, water shortage has become a serious problem facing all mankind, drought key factor restricting development agricultural production. Therefore, it is essential to study tolerance crops. Based on previous studies, we reviewed effects stress plant morphology physiology, including changes external internal structure root, stem...

Introduction Covalent attachment of isoprenoid lipids is now recognized as an important modification of many proteins involved in cellular signalling [ 1,2]. This type of modification, termed prenylation, involves attachment of either the 15-carbon farnesyl or 20carbon geranylgeranyl isoprenoid to C-terminal cysteine residues of proteins. Known prenylated proteins include a number of GTP-bindin...

Transcription factors must often be chemically modified to perform their functions. Yet, it is not known whether the mechanisms that bring about such modifications impact the quantitative or kinetic properties of gene expression. Phosphorylation controls the activity of regulatory proteins of the two-component system family, which constitutes a prevalent form of bacterial signal transduction. T...

i Abstract This thesis investigates the problem of target parameter estimation and performance analysis of multiple-input multiple-output (MIMO) radar in the presence of non-Gaussian clutter. During the past decades, multiple-input multiple-output (MIMO) radar has become a research subject of growing interest, due to its superior performance in many aspects over the traditional phased-array rad...

agronomic and physiological traits and protein expression were compared between non-bt glandless upland cotton variety-zhong5629 and its bt-transgenic near-isogenic lines differing in cryiac gene. results showed that the bt isogenic line had higher plant height and rate of effective bolls, more internal bolls but lower yield, than the non-bt line. the bt isogenic line had lower chlorophyll cont...

The functionally important regions of signal proteins participating in their specific interaction and responsible for transduction of hormonal signal into cell are rather short in length, having, as a rule, 8 to 20 amino acid residues. Synthetic peptides corresponding to these regions are able to mimic the activated form of full-size signal protein and to trigger signaling cascades in the absen...

The gene regulation mechanisms underlying hormone- and light-induced signal transduction in plants rely not only on post-translational modification and protein degradation, but also on selective inclusion and exclusion of proteins from the nucleus. For example, plant cells treated with light or hormones actively transport many signalling regulatory proteins, transcription factors, and even phot...

A number of proteins anchored on the cell surface function to protect host tissues from bystander injury when complement is activated. In humans, they include decay-accelerating factor (DAF, CD55), membrane cofactor protein (MCP, CD46), complement receptor 1 (CR1, CD35) and CD59. Although disease conditions directly attributable to abnormal function of these proteins are relatively rare, it has...
