Trees and other woody plants, such as shrubs and lianas, form the principal components in forests and many other ecosystems on our planet. Being among the largest and longest-living organisms, they support an immense share of the Earth’s terrestrial biodiversity, providing food and habitats for innumerable microorganisms, epiphytes, invertebrate, and vertebrate species. Woody species are perfect study objects, giving us a link between the past, present, and future. Woody species have also accompanied our own species throughout its evolution. Even today, billions of people depend on trees and shrubs for fuel, medicine, food, tools, fodder for livestock, shade, and watershed maintenance. Woody species therefore have a high scientific, economic, social, cultural, and aesthetic value.
However, the future of many trees and shrubs is uncertain. Ten of thousands of species are threatened by overharvesting, non-native pests and diseases, changes in accelerated land use, and climate warming. Many aspects of their biology, ecology, and biogeography are still unexplored or insufficiently understood. These knowledge shortfalls, concerning their genetic diversity, for example, significantly hinder the development of protection strategies and the elaboration of efficient action plans. This Issue, dedicated to this very diverse group of plants, aims to encourage on-going research and conservation efforts worldwide.
For this Special Issue of Plants, we therefore warmly welcome contributions (original research papers, reviews, perspectives, and opinions) on woody species and their conservation, from different fields of research, such as molecular biology, conservation biology, ecology, biogeography, and physiology.

Abstract: Understanding the genetic basis of how species response to changing environment is essential to the conservation and utilization of the species. However, the genetic mechanism of local adaptation is remains largely unknown for long-lived tree species which always have large population size, long generation time, and extensive gene flow. Recent advances of landscape genomics analysis can identify adaptive variation and spatial patterns by reveal the interaction between the genetic variation of species and landscape characteristics, and provide new insights for making tree conservation strategies. In this paper we first defining landscape genomics and briefly summarized series methods of this approaches used in tree conservation. We particular emphasis on the introduction of generalized linear mixed models, multivariate statistical analysis, non-linear models, and calculation tools involved in genotype – environment associations (GEAs) and compare the advantages and disadvantages of these methods. Secondly we review and present existing and emerging methods for landscape genomic studies on tree conservation. Specially, we introduced the newly developed method “Risk of Non-Adaptedness”, which predicts the current and future adaptability of species by combining the allele frequency and the changes in environmental factors. Finally, we provide suggestions on how these approaches can aid in making conservation strategies for tree species under climate change.
Title: Species delimitation in a species complex and impacts on conservation assessment: the case of the arid complex of Capurodendron (Sapotaceae) in Madagascar

Abstract: Reliable conservation assessments are based on the assumption that species are clearly defined units that do not overlap, which is not always the case. In a species complex of the tree genus Capurodendron (Sapotaceae) adapted to the driest regions of Madagascar, a phylogeny using 638 exonic regions revealed that a consolidated species delimitation was not achievable. We present additional advanced methodologies in target capture data (intronic region and short read repeat) to disentangle the complex, demonstrating the limits of the Linnean taxonomy when hybridization and incomplete lineage sorting blur species delimitation. We furthermore explore alternative pathways to conservation assessments for species complexes.
Title: Population genetic structure and biodiversity conservation of a relict and medicinal subshrub Capparis spinosa in arid Central Asia

Abstract: As a Tertiary Tethyan relict, Capparis spinosa is a typical wind-preventing and sand-fixing xerophytic deciduous subshrub in arid Central Asia. Due to its medicinal and energy value, this species is at risk of potential threat from human overexploitation, habitat destruction and resource plummet. Our purpose is to evaluate the genetic diversity pattern among 37 geographical distributional populations of C. spinosa and its conservation strategies according to lineage divergences and genetic structure characteristics. Based on SNPs in genomic data generated from dd-GBS sequencing, principal components analysis, maximum likelihood phylogenetic trees and ADMIXTURE clustering were performed, and significant genetic structure and divergence were found. Our results showed that: (1) Six distinct lineages were identified corresponding to geographic locations. Varying levels of genetic diversity existed among them, derived from natural habitat heterogeneity or human-caused environmental destruction. (2) The lineage divergences and morphological differences were influenced by geographic distances, isolated habitats and restricted gene flow under complexity altitudinal and topographic conditions. Finally, for the preservation of the genetic integrity of C. spinosa populations, we suggest that conservation units should be established corresponding to different geographic groups, and attention should be paid to isolated and peripheral populations that are experiencing degression in biodiversity. Simultaneously, monitoring and reducing human interferences, rational and sustainable exploiting biological resources will be beneficial to guarantee the population resilience and evolutionary potential of this xerophyte in response to environmental and climatological changes.
