The Hengduan Mountains, as one important biodiversity hotspots in the world, is notable for its high habitat heterogeneity and extreme plant diversity which including many endemics species. Incarvillea uniflora, a new species described from Mountains. similar to I. himalayensis having red corolla, stemless, solitary flower, capsule 4-angled winged seeds, but differs by characters of stable simple leaves, long triangular calyx lobes or clustered flowers. It considered be Data Deficient (DD)...

The complex physical structure and abundant repeat sequences make it difficult to assemble the mitogenomes of seed plants, especially gymnosperms. Only approximately 33 gymnosperms have been reported. However, as most widely distributed second largest family among gymnosperms, Cupressaceae has only six assembled mitogenomes, including five draft one complete mitogenome, which greatly hindered understanding mitogenome evolution within this large family, even gymnosperms.In study, we validated...

Atropa belladonna L. is one of the most important herbal plants that produces hyoscyamine or atropine, and it also anisodamine scopolamine. However, in planta content very low, difficult expensive to independently separate from tropane alkaloids A. belladonna. Therefore, vital develop with high yields hyoscyamine, without In this study, we generated scopolamine, via CRISPR/Cas9-based disruption 6β-hydroxylase (AbH6H), for first time. Hyoscyamine production was significantly elevated, while...

The cactus family (Cactaceae) has been reported to have evolved a minimal photosynthetic plastome size, with the loss of inverted-repeat (IR) regions and NDH gene suites. However, there are very limited genomic data on family, especially Cereoideae, largest subfamily cacti.In present study, we assembled annotated 35 plastomes, 33 which were representatives alongside 2 previously published plastomes. We analyzed organelle genomes genera in subfamily. These plastomes variations rarely observed...

The uncontrolled invasion of moso bamboo (Phyllostachys pubescens) dramatically alters soil nitrogen cycling and destroys the natural habitat Alsophila spinulosa. Nevertheless, no clear evidence points out role denitrifying bacteria in into A. In present study, we found that low (importance value 0.0008), moderate (0.6551), high (0.9326) invasions altered underground root biomass both P. pubescens spinulosa was maximal at invasion, indicating intermediate disturbance might contribute to...

Abstract As a hot issue, the precipitation characteristics of Three Gorges Reservoir (TGR) area drew widespread interest from domestic and overseas academic circles. Based on China's surface-based meteorological monthly data 1961 to 2016 in TGR area, spatial, inter-annual inter-decadal, multi-time-scale changes are analyzed by using Collaborative Kriging (Co-Kriging, CK) Interpolation, linear regression analysis, Morlet wavelet analysis 5-year sliding average processing, which provide...

Abstract Microorganisms are essential in soil biogeochemical processes and vegetation establishment. Nonetheless, investigating predictable patterns the microbial structure during forest restoration damaged by natural or human factors southwestern China is still limited. Hence, study intended to explore effects of illegal construction, abandoned mines, meteorological disasters on its consequence ecosystem functioning. The results uncovered that plant attributes forests construction were...

Scutellaria tsinyunensis is an endangered species in southwest China, distributed sporadically mountainous areas at elevation of approximately 200 to 900 m. Rhizosphere soil properties and fungal communities play critical roles plant survival expansion. Nevertheless, understanding the S. distribution extremely limited. The present study examined nearly all extant populations two altitudinal gradients (low high groups). Our findings indicated that characteristics (i.e., pH, water content,...

Thuja sutchuenensis Franch. is an endangered species in southwest China, distributed sporadically mountainous areas. Soil property and soil fungal community play a crucial role plant growth survival. Nevertheless, understanding properties the areas where T. extremely limited. Hence, this study collected total of 180 samples from five altitudinal distribution (altitudinal gradients) three vertical depths throughout four horizontal distances base each tree. The results found that gradients...
