Abstract

The pr-1 gene is a gene that encodes the PR-1 (Pathogenesis-Related 1) protein which plays a role in the plant defense response to pathogen infection. Although the role of the pr-1 gene as a defense protein has been known, the specific mechanism of how pr-1 responds to various types of pathogens in various plants is still poorly studied in various studies. Therefore, an in-depth analysis is needed regarding the role of the pr-1 gene in plant resistance. This study aims to determine the role of pr-1 (Pathogenesis Associated Proteins-1) gene expression on plant resistance and its implications for agricultural biotechnology. The research method used is a literature study with a qualitative approach. The results of the literature findings were then analyzed descriptively to determine the role of the pr-1 gene in the plant defense response. The findings show that the main role of the pr-1 gene is as a plant defense system against biotic and abiotic environmental threats. The plant resistance mechanism carried out by the PR-1 Protein will be active if there is PAMP/MAMP detection received by the plant cell surface receptor PRR (Pattern Recognition Receptors) to carry out the function of gene expression in plant organs.

Abstract

Abiotic stress is an environmental condition that is unfavorable for plants such as drought, salinity, heavy metal contamination and nutrient deficiencies. Prolonged abiotic stress causes the stability of plant cell organelles to be disrupted, thereby inhibiting plant growth and development. This research aims to examine the role of membrane transport in responding to environmental stress, especially abiotic stress, and the implications for plant growth and development. The research method used was a literature study using meta-analysis techniques assisted by prism diagrams in analyzing 14 relevant scientific articles from various national and international journals. The analysis was carried out descriptively on the results of previous research. The results show membrane transport has a role in increasing plant resistance to abiotic stress. Cell membrane structure consisting of lipids, proteins and carbohydrates has been proven to increase plant safety from environmental stress. So it can be concluded that membrane transport has a role in mediating tolerance, resistance, and resolving plant stress conditions through maintaining cellular homeostasis. Implications of this research can help expand knowledge about how plants respond to unfavorable environmental conditions through membrane transport mechanisms and can be basis for developing plant varieties are resistant to various forms of environmental abiotic stress.
