“…The results show that genes are not consistent between different sites, and reveal that the majority of red-heart Chinese fir genotypes are apparently not associated with geographic origin. Duan et al (2015) were unable to find an explanation for the phenomenon in the current research, and an environmental influence on red-heart in C. lanceolata remaines unclear. Similar research has also been carried out in Guangdong Province where C. lanceolata genetic samples have been collected and conserved to compile a gene pool that provided foundation of elite germplasm (Huang et al, 2006).…”

“…With such desirable features, the C. lanceolata cultigens, especially red-heart Chinese fir, could be considered for introduction to suitable sites, such as Vietnam. Recently, Duan et al (2015) utilized 21 simple sequence repeat markers to investigate the genetic characteristics of red-heart Chinese fir samples from five sites in Guangxi Province. The results show that genes are not consistent between different sites, and reveal that the majority of red-heart Chinese fir genotypes are apparently not associated with geographic origin.…”

“…In terms of basic soil physicochemical characteristics, the availability of P and organic matter (OM) followed by the availability of N have been shown to be the main factors influencing the chemical composition and quality of plants (Sun et al, 2013). Although several Chinese research groups have studied the chemical composition of red-heart Chinese fir (Huang et al, 2006;Wu et al, 2012;Liu & Zhong, 2013;Duan et al, 2015), the factors that influence chemical composition have scarcely been addressed. Nevertheless, some research relevant to red-heart wood has been reported for other species, notably Populus tomentosa (poplar), P. massoniana, and Fagus sylvatica L. (beech) (Wu et al, 2012;Vek et al, 2013).…”

Chinese fir (Cunninghamia lanceolata) is one of the most important tree species in the ecology and economy of China. This conifer has produced many cultivars following a long period of lineage divergence. Red-heart Chinese fir is a variant of Cunninghamia lanceolata, with many special characteristics and worth to promote. Some studies have shown that this excellent variant originated in Jiangxi Province. This review introduces the red-heart Chinese fir to the world and focuses on the characteristics and the economic value of this taxon. Red-heart Chinese fir is famous for the possession of a shiny, chestnut brown xylem that sorrouds the pith; the red-heart wood ratio of this species is more than 50.5%, and can be as high as 80% in mature forests. The red-heart characteristics increases this tree's value, while simultaneously decreasing the value of timber from some other species with red-heart wood, for example, Fagus sylvatica. Previous research on red-heart Chinese fir has focused on its cultivation, value and utilization, including methods of propagation, genetic resources, its chemical composition and wood application. The mechanisms that underlie the formation of these characteristics, however, have seldom been researched and discussed. Although redheart Chinese fir is one of the most valuable variants of C. lanceolata, the formation of this species has been neglected. The conclusion of this review comprises a perspective on future research, including how genetics and environment affect the formation of red-heart in Chinese fir. The relationships between the formation of red-heart Chinese fir and the properties of cambium and ray cell walls as well as other cells in the stem are important research gaps in this taxon.

Habitat fragmentation influences genetic diversity and differentiation: Fine‐scale population structure ofCercis canadensis(eastern redbud)

Forest fragmentation may negatively affect plants through reduced genetic diversity and increased population structure due to habitat isolation, decreased population size, and disturbance of pollen-seed dispersal mechanisms. However, in the case of tree species, effective pollen-seed dispersal, mating system, and ecological dynamics may help the species overcome the negative effect of forest fragmentation. A fine-scale population genetics study can shed light on the postfragmentation genetic diversity and structure of a species. Here, we present the genetic diversity and population structure of Cercis canadensis L. (eastern redbud) wild populations on a fine scale within fragmented areas centered around the borders of Georgia-Tennessee, USA. We hypothesized high genetic diversity among the collections of C. canadensis distributed across smaller geographical ranges. Fifteen microsatellite loci were used to genotype 172 individuals from 18 unmanaged and naturally occurring collection sites. Our results indicated presence of population structure, overall high genetic diversity (H E = 0.63, H O = 0.34), and moderate genetic differentiation (F ST = 0.14)among the collection sites. Two major genetic clusters within the smaller geographical distribution were revealed by STRUCTURE. Our data suggest that native C. canadensis populations in the fragmented area around the Georgia-Tennessee border were able to maintain high levels of genetic diversity, despite the presence of considerable spatial genetic structure. As habitat isolation may negatively affect gene flow of outcrossing species across time, consequences of habitat fragmentation should be regularly monitored for this and other forest species. This study also has important implications for habitat management efforts and future breeding programs.

“…Hence, a more comprehensive analysis of genetic diversity and population structure in Chinese fir is essential. Previous studies have focused on characterizing the genetic variation 21 – 26 of Chinese fir; however, the number of samples evaluated was relatively small, consisting of fewer than 150 accessions. In 2004, a set of 700 Chinese fir trees from the provinces of Guangxi (GX), Jiangxi (JX), Hunan (HN), Guizhou (GZ), Fujian (FJ) and Guangdong (GD) were conserved in the ex situ gene bank of Longshan State Forest Farm, Guangdong Province, China (25°11’N, 113°28’E, 285–296 m above sea level).…”

Large ex situ germplasm collections of plants generally contain significant diversity. A set of 700 well-conserved Chinese fir (Cunninghamia lanceolata (Lamb.) Hook) clones from six provinces in southern China in the ex situ gene bank of Longshan State Forest, was analyzed using 21 simple sequence repeat markers, with the aim of assessing the genetic diversity of these germplasm resources. Genetic analysis revealed extensive genetic variation among the accessions, with an average of 8.31 alleles per locus and a mean Shannon index of 1.331. Excluding loci with null alleles, we obtained a low level of genetic differentiation among provinces, consistent with the interpopulation genetic variation (1%). Three clusters were identified by STRUCTURE, which did not match the individuals’ geographical provenances. Ten traits related to growth and wood properties were quantified in these individuals, and there was substantial variation in all traits across individuals, these provide a potential source of variation for genetic improvement of the Chinese fir. Screening large collections for multiple-trait selective breeding programs is laborious and expensive; a core collection of 300 accessions, representative of the germplasm, was established, based on genotypic and phenotypic data. The identified small, but diverse, collections will be useful for further genome-wide association studies.
