GATA transcription factors are involved in the regulation of diverse growth processes and environmental responses Arabidopsis rice. In this study, we conducted a comprehensive bioinformatic survey family woody perennial Populus trichocarpa. Thirty-nine genes were classified into four subfamilies based on gene structure phylogenetic relationships. Predicted cis-elements suggested potential roles poplar light, phytohormone, development, stress responses. A gene, PdGATA19/PdGNC (GATA...

The cultivation of Panax notoginseng (Sanqi) within the Pinus armandii forest understory has been widely promoted in Yunnan, China. However, relatively little is known about how Sanqi influences microbial metabolic limitations and their driving factors P. ecosystems terms soil extracellular enzyme activity (EEA) stoichiometry (EES). In this study, we established monoculture (MPA) Sanqi–P. agroforestry (SPA) systems to investigate resource soils over 12 months (semi-monthly sampling)....

It is well established that the plant hormone ethylene plays a key role in cucumber sex determination. Since unisexual control gene M was cloned and shown to encode an synthase, instead of receptor, 'one-hormone hypothesis', which used explain phenotype, has been challenged. Here, physiological function CsACS2 (the encoded by locus) studied using transgenic tobacco system. The results indicated overexpression increased production plant, native promoter had no activity (PM). However, when PM...

Panax notoginseng (Sanqi) is a precious traditional Chinese medicine that commonly cultivated using conventional management methods in agricultural systems Yunnan, China, where it faces the challenge of continuous cropping obstacles (CCOs). However, existence Sanqi CCOs Sanqi–pine agroforestry remains unclear. Here, we applied three types exogenous organic acids (phthalic acid, palmitic and phthalic + mixed acids) mainly derived from root exudates to simulate CCOs; then, compared effects on...

Bioorganic fertilizers can alleviate (a) biotic stresses and sustainably increase crop yields. The effect of bioorganic on the rhizosphere bacterial community Panax notoginseng soil metabolism remains unknown. Here, we tracked changes in physicochemical properties, microbiota responses, metabolic functions after addition a fertilizer P. field. application reduced acidification, improved organic matter, increased contents total/available nutrients. Soil amendment with significantly affected...

Rhizobacterial communities and their metabolites can affect plant growth, development, stress resistance, as well the biosynthesis accumulation of bioactive compounds in medicinal plants. This relationship has been well-characterized many herbs, although much less commonly trees.Here, we analyzed composition structure Cinnamomum migao rhizobacterial across nine growing regions Yunnan, Guizhou Guangxi, China, differences soil properties fruit compounds.Results showed that C. exhibited high...

Humic acid (HA) can substantially enhance plant growth and improve soil health. Currently, the impacts of HA concentrations variation on development quality Panax notoginseng (Sanqi) from forest understorey are still unclear. In this study, exogenous was administered to roots Sanqi at varying (2, 4, 6 ml/L). Subsequently, diversity community structure bacteria fungi were assessed through high-throughput sequencing technology. The investigation further involved analyzing interplay among...

Introduction Nitrogen-fixing bacteria (NFB) have a pivotal impact on the nitrogen cycle within agroforestry systems. The organic management of Panax notoginseng (sanqi)- Pinus armandii (SPA) system resulted in deficiency because lack application chemical fertilizers. Therefore, assessing variability NFB due to cultivation sanqi SPA becomes crucial. Methods seasonal dynamics abundance, diversity, and community structure soil monocropping pine (MP) systems were assessed using real-time...

Abstract Nine guaiane‐type sesquiterpenes and one eudesmane‐type – namely argyinolides A–J ( 1 10 ) as well nine known analogues were isolated from the leaves of Artemisia argyi Levl. et Vant. Their structures determined by interpretation spectroscopic data (MS, 1D 2D NMR). A combination X‐ray crystal diffraction, specific optical rotations, CD spectroscopy, ECD calculation, Mosher ester methods was employed to resolve absolute configurations compounds. Biological investigations into their...

In rice (Oryza sativa L.), vascular bundle phloem tissue in the panicle neck is vital for transport of photosynthetic products from leaf to and positively associated with grain yield. However, genetic regulation single large area (LVPA) remains poorly understood. this study, we carried out genome-wide association analysis LVPA using 386 accessions isolated characterized gene LVPA4, which allelic NARROW LEAF1 (NAL1). Phenotypic analyses were on near-isogenic line (NIL) NIL-LVPA4LT...

Panax notoginseng is a medicinal plant in China, the flowers of which have high value. To study differences floral fragrance compounds P. (bionic wild cultivation) from forests Yunnan Province, four varieties (four-forked seven leaves, three-forked four-forked five-seven and five-six leaves) were compared analyzed via headspace solid phase microextraction combined with gas chromatography-mass spectrometry methods. A total 53 divided into eight categories, mainly consisting terpenes, alkynes,...

Land-use conversion affects the composition and assembly of plant-associated microbiomes, which in turn plant growth, development, ecosystem functioning. However, agroforestry systems, as sustainable land types, have received little attention regarding dynamics different microbes. In this study, we used high-throughput sequencing technology to analyze mechanisms driving factors pine- Panax notoginseng (P.n.)-associated microbiomes during pine forests (Pinus kesiya var. langbianensis Pinus...

Successful molecular therapy using protein-based therapeutic agents for intracellular targets depends on the development of efficient and safe protein delivery systems that are able to overcome problem poor permeability cell membrane proteins. Here, we summarize recent studies elucidating how one particular class peptide-based carriers, amphipathic peptide, has been designed utilized in a simple yet effective manner.
