“…To adapt to the changeable environment, plants have formed a variety of adaptive strategies; altering leaf morphology is one of the important adaptation mechanisms for heterophyllous plants [ 27 , 28 ]. Although heterophylly has been the subject of a preliminary study in aquatic and amphibian plants [ 6 , 10 ], the genetic basis for eco-adaptability of heterophyllous leaves is still unclear in terrestrial woody plants, and the relevant studies were mainly carried out in Populus euphratica [ 22 , 24 , 29 ]. To further clarify the mechanisms underlying heterophylly in woody plant species, we systematically and comprehensively evaluated the variation of heterophyllous leaves in a natural population of paper mulberry, which exhibits significant heterophylly and eco-adaptability [ 30 ].…”

“…Previous research has revealed that the photosynthetic capacity of heterophyllous leaves exhibits differences [ 16 , 24 ]. In our investigation, the differences in net photosynthetic rates, stomatal conductance, and transpiration rate between EL and PL also demonstrated the different photosynthetic capacities of heterophyllous leaves.…”

“…Besides, transcriptomic analysis of C. palustris identified 4275 differentially expressed genes (DEGs) between aquatic leaves and terrestrial leaves, which suggests that phytohormones and diverse transcription factors are involved in regulating the heterophylly of C. palustris [ 20 ]. A total of 56, 73, and 222 differential abundance proteins have been determined in different leaf groups through iTRAQ-based proteomic analysis in the heterophyllous woody plant P. euphratica , and differential abundance proteins are involved in photosynthesis, primary metabolite accumulation, and stress tolerance [ 24 ]. However, existing research has not been enough to uncover the eco-adaptive molecular mechanism of heterophyllous woody plants.…”

Heterophylly is regard as an important adaptive mechanism in response to different environments within plants. However, the genetic mechanisms responsible for heterophylly in woody plants are still poorly understood. Herein, the divergence of heterophyllous leaves was investigated at morphogenesis and using microdissection and physiological indexes in paper mulberry, and the genetic basis of heterophylly was further revealed combined with genome-wide association study (GWAS), transcriptome analysis and weighted gene coexpression network analysis (WGCNA). Our results revealed that the flavonoid content and antioxidant activity increased gradually from the entire leaf to the palmatisect leaf, while the hormone content and net photosynthetic rate decreased. Through GWAS and transcriptome analysis, a total of 98 candidate genes and 2338 differentially expressed genes associated with heterophylly were identified. Importantly, we uncovered critical variations in the candidate genes Bp07g0981 (WOX) and Bp07g0920 (HHO), along with significant differences in haplotypes and expression levels among heterophyllous leaves. Our results also suggested that the genes involved in hormone signaling pathways, antioxidant activity, and flavonoid metabolism might be closely related to the heterophylly of paper mulberry, which could account for the physiological data. Indeed, CR-wox mutant lines showed significant changes in leaf phenotypes, and differential expression profile analysis also highlighted the expression of genes related to phytohormones and transcription factors. Together, the genetic variations and candidate genes detected in this study provide novel insights into the genetic mechanism of heterophylly, and would improve the understanding of eco-adaptability in heterophyllous woody plants.

Populus euphratica is the only tall tree species that adapts to the desert environment. It has strong drought tolerance and is the subject of extreme concern at home and abroad. After 30 years of development, the scope of research on Populus euphratica is very extensive, but the research content has not yet been crystalized into a mature field, and research directions at home and abroad differ. In this study, we retrieved research references on ‘P. euphratica’ published from 1992 to 2022 in both the China National Knowledge Infrastructure core journals database and the Web of Science core collection database, and CiteSpace software was employed to conduct keyword-centered bibliometric analysis in both the spatial and temporal dimensions. The purpose of this study is to clarify the research areas, developmental changes, differences between domestic and international research priorities in the last 30 years, and future trends in the field of P. euphratica research. The results show that there were 1619 domestic papers published in China related to the field of P. euphratica research, while there were only 656 foreign papers in the same field. The development of domestic P. euphratica research went through three stages initiation (1992–2000), growth (2001–2008) and stability (2009–2021), whereas no significant international trend change was observed. The domestic disciplines focus on biology, while international research focuses on crop science. In terms of content, domestic research focuses on sustainable uses of P. euphratica forests and their response to drought, intending to improve P. euphratica ecosystems. International research, on the other hand, focuses on revealing mechanisms of environmental stresses, including genetic and physiological–morphological characteristics, to exploit the excellent characteristics of P. euphratica to serve agriculture and other fields. The development process of P. euphratica research in the past 30 years has generally evolved from an initial focus on its natural conditions towards the study of the relationship between environmental factors and P. euphratica physiological and morphological characteristics and, finally, the study of stress tolerance mechanisms and gene expression of P. euphratica. There is a trend towards ‘applications of P. euphratica tolerance genes’, which may represent a direction for future growth research.
