“…To understand whether the M. micrantha PIN genes were involved in responses under different stresses and treatments at the transcriptional level, transcriptome data were used to analyze their expression under abiotic stress (low-light, defoliation) and exogenous hormone (CPPU or GIC) treatment [ 35 , 36 , 40 ]. The results showed that under different hormone combinations, compared with the control group CK, the expression of PINs (E3N88_14925, E3N88_15091, E3N88_45195, E3N88_40533, E3N88_19756, E3N88_03858), which was high in the stem, was significantly up-regulated in the axillary buds treated with CPPU75 ( Figure 9 c).…”

“…Studies have shown that M. micrantha tolerates low temperature, flooding and salt stress [ 46 , 47 , 48 ], has a strong photosynthetic capacity, and tolerates a wide range of light environments [ 49 ]. Further studies have found that it not only increases the photosynthetic efficiency of stems to ensure a material basis under low light and defoliation stress, but also promoted the rapid elongation of stems by synthesizing more auxin to regulate the cell length and internode length in M. micrantha stem [ 35 , 36 , 50 ]. The results indicated that auxin regulation plays an important role in adaptation to adversity.…”

“…Moreover, one study showed that the auxin content in the stem of M. micrantha after a defoliation treatment was significantly higher than that of the control group [ 35 ]. In a shading experiment, the stem of M. micrantha also ensured rapid growth by increasing the amount of auxin, which was beneficial for its invasion under the forest [ 36 ]. Therefore, the duplication of auxin-related genes in the M. micrantha genome and the response of auxin to abiotic stress indicate that the rapid growth of M. micrantha may be related to the regulation of auxin, which largely depends on the asymmetric distribution of the auxin polar transport system [ 37 ].…”

Mikania micrantha, recognized as one of the world’s top 10 pernicious weeds, is a rapidly spreading tropical vine that has invaded the coastal areas of South China, causing serious economic losses and environmental damage. Rapid stem growth is an important feature of M. micrantha which may be related to its greater number of genes involved in auxin signaling and transport pathways and its ability to synthesize more auxin under adverse conditions to promote or maintain stem growth. Plant growth and development is closely connected to the regulation of endogenous hormones, especially the polar transport and asymmetric distribution of auxin. The PIN-FORMED (PIN) auxin efflux carrier gene family plays a key role in the polar transport of auxin and then regulates the growth of different plant tissues, which could indicate that the rapid growth of M. micrantha is closely related to this PIN-dependent auxin regulation. In this study, 11 PIN genes were identified and the phylogenetic relationship and structural compositions of the gene family in M. micrantha were analyzed by employing multiple bioinformatic methods. The phylogenetic analysis indicated that the PIN proteins could be divided into five distinct clades. The structural analysis revealed that three putative types of PIN (canonical, noncanonical and semi-canonical) exist among the proteins according to the length and the composition of the hydrophilic domain. The majority of the PINs were involved in the process of axillary bud differentiation and stem response under abiotic stress, indicating that M. micrantha may regulate its growth, development and stress response by regulating PIN expression in the axillary bud and stem, which may help explain its strong growth ability and environmental adaptability. Our study emphasized the structural features and stress response patterns of the PIN gene family and provided useful insights for further study into the molecular mechanism of auxin-regulated growth and control in M. micrantha.

“…An emerging pattern in invasion biology is that many invasive alien plants and many of the world's worst invasive plants are capable of vegetative regeneration (Liu et al 2006; Yu et al 2009; Song et al 2013). Indeed, vegetative regeneration is one of the characteristics of some highly invasive plants (Baker 1974; Sakai et al 2001; Wang et al 2017), including Eichhornia crassipes (Koutika & Rainey 2015; Yu et al 2019), Spartina anglica (Castillo et al 2017), Alternanthera philoxeroides (Chen et al 2013; Wang et al 2016 a , 2016 b ), Reynoutria japonica (Strgulc & Koce 2015), and Mikania micrantha (Li et al 2013; Jiang et al 2021). Also a considerable number of invasive plant species can perform vigorous means of vegetative regeneration that is frequently proposed to be related to their invasiveness (Kolar & Lodge 2001; Maurer & Zedler 2002; Liu et al 2006).…”

The capacity of vegetative regeneration can contribute to the invasion success of alien plant species in introduced ranges. Belowground bud bank is a trait closely related to vegetative regeneration, but it is still unknown whether belowground bud bank can help invasive alien plants to successfully invade into native plant communities. We measured bud bank density and aboveground biomass of invasive alien and native plants, and species diversity in four wetlands along a soil moisture gradient in Zhejiang Province in East China. Overall, bud bank density, aboveground biomass, and plant diversity differed significantly among the four wetlands along the soil moisture gradient. Bud bank density, aboveground biomass, and the relative dominance of invasive plants increased with increasing soil moisture, whereas bud bank density and the relative dominance of the native plants showed the opposite trend. For invasive plants, both the proportion of aboveground biomass and the relative dominance were significantly positively related to their bud proportion. These results suggest that belowground bud bank of invasive alien plant species can contribute to their successful invasion in native plant communities. Therefore, measures such as plowing and raking could be taken to destroy or restrict belowground bud bank of invasive alien plants to prevent their invasion and to restore native vegetation.
