Abstract
Organic matter (OM) amendments are often encouraged in sustainable agriculture programs
but can create heterogeneous soil environments when applied to perennial crops such as peaches
(Prunus persica (L.) Batsch). To better understand the responses of peach roots to non-uniform soil
conditions, transcriptomic analysis was performed in a split-root study using uniform soil (the same
soil type for all roots) or non-uniform soil (different soil types for each half of the root system) from
either (1) autoclaved sand (S), (2) autoclaved sand with autoclaved compost (A), or (3) autoclaved
sand with compost which included inherent biological soil life (B). Each uniform soil type (S, A, and
B) was grouped and compared by uniform and non-uniform soil comparisons for a total of nine
treatments. Comparisons revealed peach roots had differentially expressed genes (DEGs) and gene
ontology terms between soil groups, with the S and B groups having a range of 106–411 DEGs and
the A group having a range of 19–94 DEGs. Additionally, six modules were identified and correlated
(p > 0.69) for six of the nine treatment combinations. This study broadly highlights the complexity of
how OM and biological life in the rhizosphere interact with immediate and distant roots and sheds
light on how non-homogenous soil conditions can influence peach root gene expression.
