| Popis: | DNA barcodes in small packages Under adverse environmental conditions, some microorganisms form spores that provide robust protection for genetic material. Qian et al. developed a system in which DNA barcodes are encapsulated inside nongerminating microbial spores and can be dispersed on objects or in the environment (see the Perspective by Nivala). These barcoded spores provide a durable, specific marker that can be read out quickly with simple equipment. When applied to soil, the spores can be transferred to and from objects around them, enabling tracking at meter-scale resolution. On plant leaves, the spores are not readily transferred, and the authors demonstrate a potential use for tracking agricultural products. Science , this issue p. 1135 ; see also p. 1058 |
