Opuntia species (prickly pear) were deliberately introduced to many countries around the world for fruit, cochineal dye production, living fencing or as ornamentals. They are now some of the world’s most significant weeds, particularly in regions with warm and or dry climates, as they pose threats to economic and environmental assets. In addition, they can cause considerable health issues for humans and animals. Opuntia spp. have prolific reproduction abilities, being able to reproduce both vegetatively and by seed. They have generalist pollination and dispersal requirements, which promotes their establishment and spread. Opuntia stricta, O. monacantha and O. ficus-indica are the most globally widespread of the Opuntia spp. In many countries, biological control agents, particularly the cactus moth (Cactoblastis cactorum) and various cochineal insects from the Dactylopius genus, have successfully reduced land-scape scale populations. On a smaller scale, controlling these weeds by either injecting or spraying the cladodes with herbicides can provide effective control. Care must be taken during herbicide treatments as any untreated areas will regenerate. While biological control is the most cost and time effective control method for landscape-scale infestations, further research into the combined efficacy of herbicides, fire, grubbing and pre-burial techniques would be beneficial for land managers to control small-scale and establishing populations. It would also be useful to have greater knowledge of the potential seedbank longevity and seed ecology of these species so that integrated management strategies can be developed to not only deal with initial populations but also the subsequent seedling regrowth.

“…Anredera cordifolia includes highly invasive lianas, as a result of phenotypic plasticity (Pintó-Marijuan & Munné-Bosch 2013) and it is therefore classified as an "invasive plant" (Kinupp et al 2004) or "weed" (Palmer et al 2010). It is known as an "alien plant" in Australia, China, and Africa (Jian et al 2008;Baard & Kraaij 2014;Byrne et al 2017;Gao et al 2018;Shen et al 2018), where sustained effort has been put in for its control (Van Driesche et al 2010).…”

The potential of a plant with medicinal and nutritional properties, Anredera cordifolia, is reviewed. Its common names include “Bertalha” and “folha gorda” and it is popularly used for wound healing and against fungal infections and other types of infection. Its pharmacological properties have been widely investigated and acknowledged, especially with regard to its antibacterial activity, which improves the healing of wounds infected by Staphylococcus aureus, and to its antifungal activity against Candida albicans. It is an unconventional food plant, with leaves and aerial tubers used as food prepared in varied ways. It is also considered an invasive plant in several countries and thus classified as a weed. Its characteristics of a Brazilian native plant, with proven medicinal properties and unconventional use as food, underlie our study on its ecology and botanical classification, as well as the pharmacological assays and screening of chemical constituents.

“…It is considered one of the world’s worst weeds (Love et al ., 2014), invading many countries in Asia and Oceania (Day et al ., 2016; CABI, 2019;) and has been listed in China as a plant species with national quarantine concerns by the Forestry Administration (Zhang et al ., 2004; Zhang et al ., 2019). Mikania micrantha has been reported in seven provinces in southern China, with the main infestations in Guangdong, Guangxi and Yunnan provinces (Shen et al ., 2018), and affects biodiversity and a wide range of agriculture and forestry enterprises, reducing productivity through competition (Day et al ., 2016). Mikania micrantha is also known as a plant killer because its rapid growth enables it to completely smother crops or trees and block sunlight preventing flowering and fruiting (Zhang et al ., 2004; Day et al ., 2016).…”

Mikania micrantha is one of the 100 worst invasive species globally and can cause significant negative impacts to agricultural and forestry economics, particularly in Asia and the Pacific region. The rust Puccinia spegazzinii has been used successfully as a biological control agent in several countries to help manage M. micrantha. However, the response mechanisms of M. micrantha to P. spegazzinii infection have never been studied. To investigate the response of M. micrantha to infection by P. spegazzinii, an integrated analysis of metabolomics and transcriptomics was performed. The levels of 101 metabolites, including organic acids, amino acids and secondary metabolites in M. micrantha infected with P. spegazzinii, were significantly different compared to those in plants that were not infected. The relative amounts of L-leucine, L-ioleucine, L-tryptophan, histidine, L-phenylalanine and L-citrulline were increased under P. spegazzinii infection. These may convert to intermediates within the TCA cycle, participating in energy biosynthesis. In addition, phytoalexins, such as maackiain, nobiletin, vasicin, arachidonic acid and JA-Ile, were synthesized and accumulated in M. micrantha in response to P. spegazzinii infection. A total of 4,978 differentially expressed genes were identified in M. micrantha infected by P. spegazzinii. Many key genes of the Mitogen-activated protein kinase (MAPK) signalling pathway, showed significantly higher expression under P. spegazzinii infection. These results not only help us to understand the response of metabolites and gene expression in M. micrantha following infection by P. spegazzinii, but also help us understand the potential for the continuous biological control of M. micrantha using P. spegazzinii.
