Gossypium spp. pigment glands are a good model for studying plant secretory cavity structures. GoPGF (GOSSYPIUM PIGMENT GLAND FORMATION) is a well-characterized master transcription factor that controls gland formation in cotton; however, little is known about its transcriptional regulation.

Cotton is a globally cultivated crop, producing 87% of the natural fiber used in the global textile industry. The pigment glands, unique to cotton and its relatives, serve as a defense structure against pests and pathogens. However, the molecular mechanism underlying gland formation and the specific role of pigment glands in cotton's pest defense are still not well understood.

Gossypol and the related terpenoids are stored in the pigment gland to protect cotton plants from biotic stresses, but little is known about the synthetic sites of these metabolites. Here, we showed that GoPGF, a key gene regulating gland formation, was expressed in gland cells and roots. The chromatin immunoprecipitation sequencing (ChIP-seq) analysis demonstrated that GoPGF targets GhJUB1 to regulate gland morphogenesis.

In this study, three new triterpenes (-) and fourteen known triterpenoids (-) were isolated from the ethanol extract of Kochiae Fructus, and their structures were elucidated by analyzing UV, IR, HR-ESI-MS, 1D, and 2D NMR spectroscopic data. Among them, compounds , , and - were isolated for the first time from this plant. The screening results of the glucose uptake experiment indicated that compound had a potent effect on glucose uptake in 3T3-L1 adipocytes at 20 μM.

Objective: To establish a risk assessment and prediction system for early osteonecrosis of the femoral head (ONFH) in order to predict the collapse risk.

Methods: The risk assessment system for early necrosis and collapse of femoral head was established based on the combination of Steinberg stage, ABC typing and the proportion of the proximal sclerotic rim. Firstly, Steinberg stage system was applied.

is a notoriously invasive weed that can readily adapt to different environmental conditions. Control of this weed is difficult, and it spreads easily and causes damage to native habitats and agriculture. In this study, our goal was to investigate the molecular mechanisms that lead to the ability of to invade new habitats, to adapt to environmental stresses, and to cause damage.

The jasmonic acid (JA) signalling pathway plays roles in plant development and defence against biotic and abiotic stresses. We isolated a cotton NINJA (novel interactor of JA ZIM-domain) gene, designated GhNINJA, which contains a 1305 bp open read frame. The GhNINJA gene encodes a 434 amino acid peptide.

Objective: To observe the distribution of constitution types of Chinese medicine (CM) in patients with osteonecrosis of femoral head (ONFH).

Methods: Totally 130 ONFH patients were recruited. Constitution types of CM were identified in all patients.

The influence of human gut micobiota on bioaccessibilities of soil Cd, Cr, and Ni were investigated in this study. Five soil samples were collected from some sites of China, and the bioaccessibilities of soil Cd, Cr, and Ni in the gastric, small intestinal, and colon phases were determined using the PBET method (physiologically based extraction test) combined with SHIME model (simulator of human intestinal microbial ecosystem). The results showed that the bioaccessibilities of Cd, Cr, and Ni in the gastric phase were 4.

Boea hygrometrica resurrection plants require a period of acclimation by slow soil-drying in order to survive a subsequent period of rapid desiccation. The molecular basis of this observation was investigated by comparing gene expression profiles under different degrees of water deprivation. Transcripts were clustered according to the expression profiles in plants that were air-dried (rapid desiccation), soil-dried (gradual desiccation), rehydrated (acclimated) and air-dried after acclimation.

To observe the clinical effect of Jianpi Bushen formula to prevent the collapse of osteonecrosis of femoral head (ONFH) of type phlegm and blood stasis obstructing the collaterals. 50 cases (including 73 hips) of non-collapse ONFH (ARCO I, II, III a) were selected from the out-patient department of orthopedic in Guang'anmen Hospital attached to China Academy of Chinese Medical Science. All the cases fit for diagnostic criteria were given Jianpi Bushen formula and followed up.
