Ecological regulation of water level should be combined with seed supplementation for lakeshore Carex community restoration in Yangtze-disconnected lakes.

Carex communities in most Yangtze-disconnected lakes have been degraded severely due to alterations in water level fluctuations. To explore the feasibility of restoring the lakeshore Carex communities through ecological regulation of water level, the present study selected the Yangtze-connected Qili Lake (the lakeshore was dominated by Carex) and the Yangtze-disconnected Wuchang Lake (the lakeshore was dominated by Zizania latifolia) as model systems, and analyzed the lakeshore seed bank characteristics and seed-related quantitative, morphological, and germination traits of three representative Carex species. According to the results, although Carex seed density in the Qili Lake seed bank was obviously higher than that in Wuchang Lake, their contribution to the total seed density in both lakes was extremely low, with no significant difference between the two lakes.

Soil calcium prompts organic carbon accumulation after decadal saline-water irrigation in the Taklamakan desert.

Soil organic carbon (SOC), as a crucial measure of soil quality, is typically low in arid regions due to salinization, which is a global issue. How soil organic carbon changes with salinization is not a simple concept, as high salinity simultaneously affects plant inputs and microbial decomposition, which exert opposite effects on SOC accumulation. Meanwhile, salinization could affect SOC by altering soil Ca (a salt component), which stabilizes organic matter via cation bridging, but this process is often overlooked.

is a basic helix-loop-helix transcription factor that confers enhanced root growth and tolerance to salt stress in poplar.

The basic helix-loop-helix (bHLH) family of transcription factors is one of the largest and oldest transcription factor families in plants. Members of the bHLH family regulate various growth and metabolic processes in plants. We used quantitative trait locus (QTL) mapping and transcriptome sequencing (RNA-seq) to identify as a candidate bHLH transcription factor associated with root dry weight (RDW) in poplar.

Histone H3K9 acetylation modulates gene expression of key enzymes in the flavonoid and abscisic acid pathways and enhances drought resistance of sea buckthorn.

The effect of histone H3K9 acetylation modification on gene expression and drought resistance in drought-resistant tree species is not clear. Using the chromatin immunoprecipitation (ChIP) method, this study obtained nine H3K9 acetylated protein-interacting DNAs from sea buckthorn seedlings, and the ChIP sequencing result predicted about 56,591, 2217 and 5119 enriched region peaks in the control, drought and rehydration comparative groups, respectively. Gene functional analysis of differential peaks from three comparison groups revealed that 105 pathways were involved in the drought resistance process, and 474 genes were enriched in the plant hormone signaling transduction pathways.

Mating pattern and pollen dispersal in an advanced generation seed orchard of (Lamb.) Hook.

Seed orchards represent the link between forest breeding and conifer production forests, and their mating patterns determine the genetic quality of seed orchard crops to a large extent. We genotyped the parental clones and their open pollination offspring in the third-generation seed orchard of Chinese fir using microsatellite markers and observed the synchronization of florescence in the seed orchard to understand the genetic diversity and mating structure of the seed orchard population. Genetic coancestry among parental clones was detected in the third generation seed orchard of Chinese fir, and the genetic diversity of the open-pollinated offspring was slightly higher than that of the parental clones.
