Alternative splicing is a molecular tool of the cell to generate more than one messenger RNA from the same gene. Through variable combinations of exons blueprints for different proteins are assembled from one and the same pre-messenger RNA, thus increasing the complexity of the proteome. Moreover, through alternative splicing different transcript variants with different stabilities and different regulatory motifs can be generated, leading to variation in the transcriptome. The importance of alternative splicing in plants has been increasingly recognized in the last decade. Alternative splicing has been found during abiotic and biotic stress and during development. Here, recent advancements in the understanding of alternative splicing in higher plants are presented. Mechanistic details and functional consequences of alternative splicing are discussed with a focus on the model plant Arabidopsis thaliana.

Biochemical Mechanisms

In general mechanics stress is clearly defined as the point or degree of bending of an elastic system at the very point of just symptomless reversibility and irreversible deformation or break. In medicine and botany, stress is supposed to indicate all situations beyond normal, defined by the observer. All organs of higher plants (with some exceptions) perform aerobic metabolism and are thus subject to activated oxygen species. Oxygen oversaturation and thus oxygen stress may occur under various different conditions. Since most abiotic and biotic stress situations in plants result in the accelerated production of ROS oxidative stress is a common signaling event in plant stress and redox regulation therefore plays a central role in the stress signaling network (PASTORI & FOYER 2002). In this review basic reactions operating during stress and defence will be discussed where certain prooxidative situations and antioxidative processes in plants will be dealt with.
