Pinus_halepensis_2021_16sV4
Root-associated 16S rRNA (V4 region) sequences from Aleppo pine (*Pinus halepensis* Mill.) seedlings, grown from Mediterranean-origin seeds (ONF-PNRGF, Cadarache, France). Seedlings were exposed to two water regimes, well-watered (60% field capacity) and drought (40% field capacity), and classified into three drought-response phenotypes: non-affected, moderately affected, and severely affected. Sequencing targeted the root microbiome to characterize bacterial community composition across watering regimes and phenotypic responses.
