Genome-wide identification of CRF gene family members in four rice subspecies and expression analysis of OsCRF members in response to cold stress at seedling stage.

Cytokinin Response Factors (CRFs) play a crucial role in plant growth and development, hormone signaling, and responses to biotic and abiotic stresses. However, there have been no reports on CRF genes in rice until now. We analyzed the CRF families in four rice subspecies: cultivated rice Oryza sativa Japonica Group, Oryza sativa Indica Group, and Oryza sativa (circum-Aus1 var.

Impact of Through-Hole Defects on the Electro-Explosive Properties of Exploding Foil Transducers.

This study examines the impact of surface defects on the electro-explosive properties of metal explosive foil transducers. Specifically, it focuses on the effects of defects in the bridge foil and their influence on the electrical explosion time and transduction efficiency. To analyze these effects, a current-voltage simulation model is developed to simulate the behavior of a defective bridge foil.

on links to salt tolerance at the seeding stage in L. ssp. .

Rice has been reported to be highly sensitive to salt stress at the seedling stage. However, the lack of target genes that can be used for improving salt tolerance has resulted in several saline soils unsuitable for cultivation and planting. To characterize new salt-tolerant genes, we used 1,002 F populations derived from Teng-Xi144 and Long-Dao19 crosses as the phenotypic source to systematically characterize seedlings' survival days and ion concentration under salt stress.

is Related to the Type III Effector NopAA to Promote Nodulation in Soybean ().

Type III effectors secreted by rhizobia regulate nodulation in the host plant and are important modulators of symbiosis between rhizobia and soybean (), although the underlying mechanisms are poorly understood. Here, we studied the type III effector NopAA in HH103, confirming its secretion into the extracellular environment under the action of genistein. The enzyme activity of NopAA was investigated , using xyloglucan and β-glucan as substrates.

QTL mapping and candidate gene mining of flag leaf size traits in Japonica rice based on linkage mapping and genome-wide association study.

Background: As one of the most important factors of the japonica rice plant, leaf shape affects the photosynthesis and carbohydrate accumulation directly. Mining and using new leaf shape related genes/QTLs can further enrich the theory of molecular breeding and accelerate the breeding process of japonica rice.

Methods: In the present study, 2 RILs and a natural population with 295 japonica rice varieties were used to map QTLs for flag leaf length (FL), flag leaf width (FW) and flag leaf area (FLA) by linkage analysis and genome-wide association study (GWAS) throughout 2 years.

A dual-functional probe for sensing pH change and ratiometric detection of Cu.

A series of benzothiazole-based compounds were synthesized and characterized. Among them, probe Z showed significant dual-functional performance which was capable of sensing pH change and Cu. Probe Z displayed fluorescent turn-on under alkaline conditions due to deprotonation of the hydroxyl group along with the obviously color change from colorless to mint green.
