In a total DNA library from the poplar clone Beaupré (Populus trichocarpa x P. deltoides) one DNA clone was found to identify restriction site polymorphisms in different poplar species. This clone represents a cpDNA gene that shows close homology to a photosystem II gene of pea and spinach coding for the D2 protein and the 44 kDa reaction centre. In Southern blot analysis this probe identified interspecific restriction site variation among the different poplar species; intraspecific variation was not detectable. As the chloroplast genome is maternally inherited in poplars this cpDNA probe was used for identification of P. nigra or P. deltoides as the seed parents of F1 hybrid trees in natural stands of western Germany.

In natural environments, the growth and development of trees are continuously affected by phosphorus (P) starvation stress. However, the mechanisms through which trees balance stem growth and P distribution remain unknown. This study found that in the woody model species poplar, the P loss in stems is more severe than that in roots and leaves under P starvation conditions, thereby inhibiting stem development and reducing the expression of numerous genes related to wood formation, including PagSND1-B1.

Modulation of stomatal development and movement is a promising approach for creating water-conserving plants. Here, we identified and characterized the PagHCF106 gene of poplar (Populus alba × Populus glandulosa). The PagHCF106 protein localized predominantly to the chloroplast, and the PagHCF106 gene exhibited tissue-specific expression pattern.

The ambrosia beetle Blandford (Coleoptera: Curculionidae: Scolytinae) has recently emerged as a pest in Chinese poplar plantations, causing significant economic losses through damage to host trees in association with its mutualistic fungus . This study evaluated the biocontrol potential of strain B-BB-1, strain B-SM-1, its metabolite prodigiosin, and two ectoparasitic mites, and . exhibited significant lethality toward adult female , reduced offspring production, and inhibited growth.

The poplar moth, (Lepidoptera: Lyonetiidae), is widely distributed across Europe, Asia, and parts of Africa. It was first identified in Chile in 2015 and has since become a significant pest in the agricultural sector. Additionally, economic losses are further aggravated by the presence of pupae in nearby fruit orchards.

Populus tree species are commonly used for creating shelter forests in vast areas of northern China, at least partially due to their fast growth. However, they are facing severe problems of decline and mortality caused by drought. In contrast, tree species native to water-limited environments usually have slow growth and are currently not commonly used in afforestation, while these species are gaining more attention in forestry for their greater resilience to drought.
