Abstract Background Yellow nutsedge (YSD, Cyperus esculentus) and purple (XFZ, rotundus), closely related Cyperaceae species, exhibit significant differences in triacylglycerol (TAG) accumulation within their tubers, a key factor carbon flux repartitioning. Previous studies have attempted to elucidate the anabolic discrepancies between these two however, lack of comprehensive genome-wide annotation has hindered detailed understanding underlying molecular mechanisms. Results This study utilizes transcriptomic analysis, supported by YSD reference genome, metabolomic profiling uncover mechanisms TAG-based differentiation developing tubers XFZ germplasms harvested Yunnan province, China. Our findings indicate distinct expression patterns regulatory genes involved TAG biosynthesis lipid droplet formation, including ABI3 transcriptional factor, rate-limiting enzymes GPAT3/6/9 DGAT2/3, oleosin caleosin homologs.

Yellow nutsedge (Cyperus esculentus, known as 'YouShaDou' in China, YSD) and purple rotundus, 'XiangFuZi' XFZ), closely related Cyperaceae species, exhibit significant differences triacylglycerol (TAG) accumulation within their tubers, a key factor carbon flux repartitioning that highly impact the total lipid, carbohydrate protein metabolisms. Previous studies have attempted to elucidate anabolic discrepancies between these two however, lack of comprehensive genome-wide annotation has hindered detailed understanding underlying molecular mechanisms. This study utilizes transcriptomic analyses, supported by YSD reference genome, metabolomic profiling uncover mechanisms major perturbations developing tubers XFZ germplasms harvested Yunnan province, where plant biodiveristy is renowned worldwide may contain more genetic variations relative counterparts other places. Our findings indicate distinct expression patterns regulatory genes involved TAG biosynthesis lipid droplet formation, including transcriptional factors structural such ABI3 factor, rate-limiting enzymes GPAT3/6/9 DGAT2/3, oleosin caleosin homologs. Furthermore, our omics data suggest gene are not sole contributors diverse tuber compositions. Instead, complex interactions among regulated catalytic reactions, governing carbohydrate, protein, species-specific metabolite metabolisms, starch sucrose metabolic pathways, flavonoid amino acids biosynthetic collectively contribute pronounced differentiation primarily evident accumulation, well properties mature tubers. offers new insights into high-value underground non-photosynthetic tissues which harbors only high biomass productivity but also abundant nutrients favorable food or industrial sources modern agriculture.

Soil diversity plays an important role in maintaining ecological balance and ensuring the sustainability of land. Xinjiang is a typical arid semi-arid region China, study soils significant for understanding soil properties all such environments. This applied moving window technique species–area curve model from ecology to establish optimal analysis windows, calculate landscape pattern indices, reveal distribution characteristics Southern Xinjiang. Additionally, we used geographic detectors identify primary influencing factors different geomorphic regions. The results indicate positive correlation between richness area region. Tarim Basin, despite being largest area, shows lowest evenness indices. Overall, mountainous areas have higher when compared basins. In terms natural factors, temperature, precipitation, topography play crucial variation areas, while parent material has greater influence basin vary by are influenced interactive effects various factors. However, impact human activities also requires consideration. low poses challenge restoration conservation efforts regions paramount importance. research findings can provide valuable insights development sustainable agriculture, conservation, addressing climate change challenges

Archaea and bacteria communities play pivotal roles in tropical forest ecosystems’ functioning, especially nutrient cycling, plant phenology, health. The objective of this study was to explore the diversity archaeal bacterial soil ecosystem Côte d’Ivoire identify abiotic factors that influence their composition. Using high-throughput amplicon sequencing targeting V4V5 hypervariable region 16S ribosomal RNA gene, we analyzed 22 samples taken from 2 main areas d’Ivoire, namely semi-deciduous moist evergreen forest, both which are located humid sub-humid country. analysis revealed biodiversity at phyla level congruent with previous studies. Richness Shannon indices dominance over archaea all studied soils. Moreover, predominant community consisted Proteobacteria (29.8%), Acidobacteria (15.5%), Actinobacteria (14.2%), while dominated by Thaumarchaeota (1.93%). However, genus level, patterns emerged. most abundant ubiquitous members included Bradyrhizobium, Rhodoplanes, Bacillus (bacteria), Nitrosophaera (archaea). While core microbiome were found almost soils, Nitrososphaera selective bioclimate cropland land use. These correlated soils’ physicochemical characteristics, bioclimate, This sheds light on intricate relationships between microbial d’Ivoire’s soils helps keys species for future management.
