Enhancing soil health and strawberry disease resistance: the impact of calcium cyanamide treatment on soil microbiota and physicochemical properties.

Introduction: Continuous strawberry cropping often causes soil-borne diseases, with 20 calcium cyanamide being an effective soil fumigant, pig manure can often be used as soil organic fertilizer. Its impact on soil microorganisms structure, however, remains unclear.

Methods: This study investigated the effectiveness of calcium cyanamide and pig manure in treating strawberry soil, specifically against strawberry anthracnose.

GPC3-IL7-CCL19-CAR-T primes immune microenvironment reconstitution for hepatocellular carcinoma therapy.

Background: Chimeric antigen receptor (CAR)-T-cell therapy is a revolutionary treatment that has become a mainstay of advanced cancer treatment. Conventional glypican-3 (GPC3)-CAR-T cells have not produced ideal clinical outcomes in advanced hepatocellular carcinoma (HCC), and the mechanism is unclear. This study aims to investigate the clinical utility of novel GPC3-7-19-CAR-T cells constructed by our team and to explore the mechanisms underlying their antitumor effects.

Melatonin reduces cadmium accumulation via mediating the nitric oxide accumulation and increasing the cell wall fixation capacity of cadmium in rice.

Melatonin (MT) is participated in plants' response to cadmium (Cd) tolerance, although its work model remains elusive. Here, the function of MT in adjusting Cd accumulation in rice was investigated. 'Nipponbare' (Nip) was cultured in the -Cd (1/2 Kimura B), -Cd + MT (1/2 Kimura B with 1 μM MT), +Cd (1/2 Kimura B plus 1 μM Cd) and +Cd + MT (1/2 Kimura B with 1 μM Cd and 1 μM MT) nutrient solutions for 7 d.

Physiological and biochemical responses of Ulva prolifera and Ulva linza to cadmium stress.

Responses of Ulva prolifera and Ulva linza to Cd(2+) stress were studied. We found that the relative growth rate (RGR), Fv/Fm, and actual photochemical efficiency of PSII (Yield) of two Ulvaspecies were decreased under Cd(2+) treatments, and these reductions were greater in U. prolifera than in U.

[Physiological responses of Enteromorpha linza and Enteromorpha prolifera to seawater salinity stress].

To investigate the physiological responses and adaptation mechanisms of Enteromorpha to seawater salinity stress, a laboratory experiment with Enteromorpha linza and E. prolifera was conducted to study their fresh mass (FM), relative growth rate (RGR), relative electrical conductivity (REC), chlorophyll (Chl) and carotenoid (Car) contents, Chl a/Chl b, Chl/Car, chlorophyll fluorescence parameters, and osmotic adjustment ability (OAA) under the stress of different salinity levels of diluted and concentrated seawater for 10 days. Compared with the control, 10%-200% salinity seawater increased the FM and RGR of the two Enteromorpha species obviously, 100% and 50% salinity seawater made the FM and RGR of E.

[Impact of high salt stress on Apocynum venetum growth and ionic homeostasis].

A pot experiment was conducted in a net room to study the growth responses and related mechanisms of Apocynum venetum treated with different concentrations (100-400 mmol x L(-1)) of NaCl for 30 days. The biomass accumulation, growth rate, root vigor, salt ion content and mineral ion uptake and distribution were measured. Compared with the control, treatment 100 mmol x L(-1) NaCl had lesser effects on the plant dry mass, but decreased the plant fresh mass and growth rate significantly.

[Comparison of seed oil physicochemical characteristics among three cultivars of Jatropha curcas L].

Taking the cultivars Nanyou 1, 2, and 3 of barbadosnut (Jatropha curcas L. ) with different genotypes that can grow and seed normally at the inshore land in Hainan as test materials, the characters of their seeds and the physicochemical characteristics of their seed oils were analyzed and compared. No significant differences were observed in the seed length, width, thickness, and surface area among the cultivars, but Nanyou 2 had greater 1000 seed mass and lower unsound kernel percentage than Nanyou 1 and Nanyou 3, suggesting that the seed satiation of Nanyou 2 was good and the fecundity was excellent.

Silicate improves growth and ion absorption and distribution in aloe vera under salt stress.

Si 2.0 mmol/L in irrigation solution alleviated significantly the inhibition of NaCl stress of 100 or 200 mmol/L to aloe growth. Exogenously applied Si decreased significantly Na(+) and Cl(-) contents, increased K(+) content and K(+)/Na(+) ratio and selectivity ratio of absorption (AS(K, Na)) and of translocation (TS(K, Na)) to K(+) and Na(+) in aloe plant under both NaCl 100 and 200 mmol/L stresses for 30 d.

[Salt-tolerance evaluation of seedlings of medicinal Chrysanthemum morifolium cultivar].

Objective: To evaluate salt tolerance of seedlings of 4 medicinal C. morifolium cultivars to be transplanted, and to expand the planting area.

Method: Seedlings were cultivated in hoagland nutrient solution containing various concentrations of NaCl for 30 days.
