soil-to-plant-transfer
Soil-to-plant transfer describes the process by which minerals, nutrients, and contaminants move from the soil matrix into plant roots and are subsequently distributed throughout plant tissues. Understanding this transfer is essential for plant science because it governs nutrient uptake efficiency, growth, and metabolic quality, while also determining how environmental pollutants like heavy metals can accumulate in edible or harvested plant parts. Studying these pathways helps researchers assess food safety risks and develop strategies to optimize soil conditions for healthier crop production.

Soil acts as the primary microbial source for tea tree bark, seeding the bark with bacteria and fungi that then specialize for life on the tree. Geography and soil chemistry — especially nitrogen and organic matter — are the main forces shaping which microbes end up where.
Bulk soil supplied 100% of bark bacteria and 68% of bark fungi in the Pu'er region, confirming soil as the dominant microbial reservoir for tea tree bark.
Plant type (cultivar) explained 76% of variation in bark bacterial communities, while geographic location explained up to 79% of fungal variation in soil.
Total nitrogen and organic matter in soil were the strongest predictors of microbial community composition across both soil and bark niches.
