Based on an optically injected semiconductor laser (OISL) operating at period-one (P1) nonlinear dynamical state, tunable and ultrabroadband microwave frequency combs (MFCs) are generated experimentally through further current-modulating the OISL. First, by introducing an injection light with an inj...

The cDNA of coat protein gene and its 3′ non-coding region of tobacco mosaic virus and coat protein gene of cucumber mosaic virus isolated from the tobacco in Yunnan province was synthesized by RT-PCR. The amplified cDNA fragments were then cloned and sequenced. The fragment of TMV-YN comprises 684b...

The aphid quantity ratio (AQR) is defined as the number of aphids on each cultivar divided by the number of aphids on all cultivars. AQR is based on the correlation between aphid populations and their host plants and is an important tool that has been utilized in evaluating Medicago sativa (alfalfa)...

To explore the regulation mechanism of TCP4 gene on the development of petal spur of Impatiens uliginosa, the full length cDNA of TCP4 gene in I. uliginosa (named as IuTCP4) was cloned by reverse transcription polymerase chain reaction, and its sequence was analyzed by bioinformatics. Then, real-tim...

Inheritance and interrelationship of phenotype and genotype of earliness traits were evaluated in a diallel analysis involving six early-maturing parents. Date of first square (DFS), date of first flower (DFF), date of first open boll (DFOB), number of node first sympodial branch (NNFSB), and harves...

Bladder cancer (BC) is a prevalent and aggressive malignancy with high recurrence. Autophagy plays a dual role in cancer, acting as a tumor suppressor early on and promoting survival in later stages. NR4A3, a nuclear receptor with tumor-suppressive effects in other cancers, has not been explored in...

Purpose: Computed tomography (CT) screening has established itself as the routine method to monitor lung conditions by providing pulmonary structural and functional information. However, the reference ranges of CT indices are still lacking. Therefore, this study aimed to provide reference ranges for...

In this work, a novel optoelectronic oscillator (OEO) structure is proposed for generating widely tunable photonic microwave. In this structure, an optical injection semiconductor laser (OISL) functions as an active tunable microwave photonic filter (MPF). Through controlling the injection power and...

The thrips quantity ratio (TQR) model is an important tool for evaluating crop resistance to thrips based on the correlation between thrips quantities and cultivars. Unfortunately, it is inaccurate, and the results appear significantly inconsistent when analysing the same cultivars in the same field...

The foundation parents play key roles in the genetic improvement of both yield potential and end-use quality in wheat. Characterizing the genetic basis that underlies certain beneficial traits in the foundation parents will provide theoretical reference for molecular breeding by a design approach. ‘...

The WRKY proteins constitute a large family of transcription factors in plants containing highly conserved WRKYGQK sequences and zinc-finger-like motifs. To comprehensively study WRKY III genes in cotton, we analyzed the genome sequences of Gossypium hirsutum, G. raimondii and G. arboreum. According...

Plant calcium-dependent protein kinases (CDPKs) play important roles in diverse physiological processes by regulating the downstream components of calcium signaling. To date, only a few species of the plant CDPK gene family have been functionally identified. In addition, there has been no systematic...
