Regulation of Ethylene Biosynthesis and ..

Cascades by which signalling molecules participate in plant responses to changes in environmental conditions are still under intensive study. Our aim was to explain the role of NO, H2O2 and H2S in adaptation of cucumber seedlings to both salt and low temperature stress. Results show that signalling molecules are important for understanding the mechanisms of modification of the activity of the plasma membrane proton pump, which is a key enzyme in abiotic stress conditions.

Clearly, the UPS plays a significant role in ethylene biosynthesis and response. Although the UPS is involved in the synthesis and signaling responses of other hormones as well, the full extent to which this occurs remains to be seen. As research progresses, it may be revealed that protein turnover is the primary mode of regulation in controlling hormone responses in plant systems.

Ethylene Biosynthesis and its Regulation in Higher Plants

In the study presented we identified genes in apple and analysed their response to biotic/abiotic stress. The aim of the work was to give references to understand the function of genes generally and serve as a reference for studies of Dof zinc finger genes in other plants. Finally, we fit the original images into the software Photoshop 6.0 for bigger pictures.

Chilling stress limits the productivity and geographical distribution of many plants throughout the world. Accumulation of the endoplasmic reticulum-located small heat shock protein HSP22.5 enhanced photochemical activity and oxidation resistance and alleviated endoplasmic reticulum stress caused by chilling stress in transgenic tobacco plants. HSP22.5 could be useful for improving the tolerance of chilling-sensitive plant types.

Plants utilize hormones to control growth and development and to respond quickly to ever-changing environmental conditions. Without precise controls over both the production of and response to these hormones, plants would not be able to survive. In recent years, it has been found that ubiquitin-mediated protein degradation is a key mechanism through which plants are able to quickly modulate their responses to hormones. Protein degradation has been shown to be involved in controlling responses to most hormones, including auxins, gibberellins, jasmonates, abscisic acid, and ethylene [–]. The presence of this strategy in hormone response control indicates that it is a vital component of the plant's ability to respond to developmental and environmental changes.

The gaseous hormone ethylene is an important regulator of developmental processes and responses to environmental changes in plants. These processes include fruit ripening, senescence, organ abscission, seed germination, and stress responses []. Through a variety of genetic and biochemical approaches, our knowledge of how ethylene is synthesized and perceived by plants has been significantly advanced. Protein degradation is increasingly recognized as an important mechanism governing ethylene biosynthesis and perception. This review focuses on the emerging role that protein degradation plays in these processes. In the first section, we provide an overview of proteasome-mediated protein degradation, and then we discuss protein degradation in the ethylene biosynthetic pathway. Next, we cover the recent finding that ethylene receptors are regulated via proteasome-dependent proteolysis. We then discuss what is now considered to be a key step in ethylene signaling: the degradation of the ethylene response transcription factor EIN3. Finally, we consider possible future directions for research in ethylene perception.

Male Sterility

The plants may inherit male sterility either from the nucleus or cytoplasm. It is possible to introduce male sterility through genetic manipulations while the female plants maintain fertility. In tobacco plants, these are created by introducing a gene coding for an enzyme (barnase, which is a RNA hydrolyzing enzyme) that inhibits pollen formation. This gene is expressed specifically in the tapetal cells of anther using tapetal specific promoter TA29 to restrict its activity only to the cells involved in pollen production. The restoration of male fertility is done by introducing another gene barstar that suppresses the activity of barnase at the onset of the breeding season. By using this approach, transgenic plants of tobacco, cauliflower, cotton, tomato, corn, lettuce etc. with male sterility have been developed.

Ethylene (CH, also known as ethene) is a gaseous organic compound that is the simplest of the alkene chemical structures (alkenes contain a carbon-carbon double bond). Ethylene is the most commercially produced organic compound in the world and is used in many industrial applications. Ethylene is also a gaseous plant hormone.
