Abstract

Soil salinity is a major limiting factor in global agricultural production, affecting plant growth, physiology, and yield, and poses a major threat to global agricultural productivity. The accumulation of Na⁺ and Cl⁻ ions cause osmotic stress, ion toxicity, and metabolic disorders in plants. Developing salinity-tolerant crop varieties is an important strategy for increasing the productivity of marginal lands. Modern biotechnological approaches such as genetic engineering and marker-assisted selection (MAS) enable the development of superior varieties more quickly and accurately than conventional methods, offering a rapid and precise solution for developing salt-tolerant crop varieties. Genetic engineering allows the direct introduction of salinity tolerance genes, while MAS allows the selection of tolerance genes based on molecular markers. This article reviews the basic mechanisms of salinity stress, the role of tolerance-related genes, and biotechnological strategies used in plant breeding. An integrative approach between genetic engineering and MAS is an effective strategy for producing varieties adaptive to saline soils in modern plant breeding (Munns & Tester, 2008; Flowers & Colmer, 2015).

Abstract

The rapid development of digital financial technology has significantly transformed investment activities by providing easier access to financial markets through digital investment applications. This study aims to explore the perceptions and experiences of beginner investors in making investment decisions in the digital era. Using a qualitative research approach with a phenomenological perspective, data were collected through semi-structured interviews with beginner investors who actively use digital investment applications. The collected data were analyzed using thematic analysis to identify patterns and themes related to investors’ experiences and decision-making processes. The findings reveal that investment decision-making among beginner investors is influenced by several interconnected factors, including the accessibility and usability of digital investment platforms, the influence of social media and online communities, the development of financial literacy, and psychological experiences related to investment gains and losses. Digital investment applications play a crucial role in lowering barriers to market participation by providing user-friendly interfaces and accessible financial information. However, reliance on social media as a source of investment information may also expose investors to misinformation and speculative investment behavior. In addition, emotional responses such as confidence, fear, and uncertainty often influence investment decisions among beginner investors. Overall, the study highlights that investment decision-making in the digital era is a multidimensional process shaped by technological accessibility, social influence, financial knowledge, and psychological factors. These findings contribute to a deeper understanding of investor behavior in digital financial environments and emphasize the importance of financial education and responsible investment practices.
