Abstract Epithelial growth factor receptor (EGFR) mutations are present in 10%–26% of non-small cell lung cancer (NSCLC) tumors and are associated with the response to tyrosine kinase inhibitors (TKIs). This study aimed to detect and quantify the presence of circulating tumor cells (CTCs) in EGFR-mutant NSCLC patients and investigate their possible role in providing prognostic information. Enrolled patients received erlotinib (150 mg) or gefitinib (250 mg) orally once daily as the first-line treatment. Serial blood samples were taken at baseline (CTC-d0) and on day 28 (CTC-d28) following the initiation of erlotinib/gefitinib for detection of CTCs using… More >

Abstract The phenotype of a common bean plant is often closely related to its yield, and the yield of plants with reduced height or poor stem development during growth is low. Mutants serve as an essential gene resource for common bean breeding genetic research. Although model plants and crops are studied to comprehend the molecular mechanisms and genetic basis of plant phenotypes, the molecular mechanism of phenotypic variation in common beans remains underexplored. We here used the mutant ‘nts’ as material for transcriptome sequencing analysis. This mutant was obtained through ⁶⁰Co-γ irradiation from the common bean variety… More >

Abstract OsPLS4 encodes a β-ketoacyl carrier protein reductase (KAR). The role of OsPLS4 in rice sheath blight (Rhizoctonia solani) remains unclear. Our preliminary studies showed that premature leaf senescence mutants (pls4) were highly susceptive to sheath blight in the early stage of rice development. To explore the role of this gene in the development of rice sheath blight, the transcriptome profiles of the rice pls4 mutant and wild type were compared by RNA-seq. The results revealed 2,569 differentially expressed genes (DEGs). The down-regulated genes were significantly enriched in the defense response-related biological processes. These down-regulated genes included the chitinase… More >

Abstract Peanut (Arachis hypogaea L.) is an oil and economic crop of vital importance, and peanut pod is the key organ influencing the yield and processing quality. Hence, the Pod-related traits (PRTs) are considered as important agronomic traits in peanut breeding. To broaden the variability of PRTs in current peanut germplasms, three elite peanut cultivars were used to construct Ethyl methane sulfonate (EMS)-induced mutant libraries in this study. The optimal EMS treatment conditions for the three peanut varieties were determined. It was found that the median lethal dose (LD50) of EMS treatment varied greatly among different genotypes.… More >

Abstract Leaf-color mutants play an important role in the study of chlorophyll metabolism, chloroplast development, and photosynthesis system. In this study, the yellow leaf 1 (yl1) rice mutant was identified from the ethyl methane sulfonate-treated mutant progeny of Lailong, a glutinous japonica rice landrace cultivated in Guizhou Province, China. Results showed that yl1 exhibited yellow leaves with decreased chlorophyll content throughout the growth period. Chloroplast development in the yl1 mutant was disrupted, and the grana lamellae was loosely packed and disordered. RNA sequencing and real-time quantitative polymerase chain reaction (qRT-PCR) analysis revealed that the chlorophyll synthesis-related genes OsCHLH, OsCHLM, OsCHLG, PORB,… More >

Abstract Cloud computing is providing IT services to its customer based on Service level agreements (SLAs). It is important for cloud service providers to provide reliable Quality of service (QoS) and to maintain SLAs accountability. Cloud service providers need to predict possible service violations before the emergence of an issue to perform remedial actions for it. Cloud users’ major concerns; the factors for service reliability are based on response time, accessibility, availability, and speed. In this paper, we, therefore, experiment with the parallel mutant-Particle swarm optimization (PSO) for the detection and predictions of QoS violations in More >

Abstract Enhancing photosynthesis efficiency is considered as one of the most crucial targets during wheat breeding. However, the molecular basis underlying high photosynthesis efficiency is not well understood up to now. In this study, we investigated the protein expression profile of wheat Jimai5265yg mutant, which is a yellow-green mutant with chlorophylls b deficiency but high photosynthesis efficiency. Though TMT-labeling quantitative proteomics analysis, a total of 72 differential expressed proteins (DEPs) were obtained between the mutant and wild type (WT). GO analysis found that they significantly enriched in thylakoid membrane, pigment binding, magnesium chelatase activity and response More >

Abstract Leaf color mutants are ideal materials for studying many plant physiological and metabolic processes such as photosynthesis, photomorphogenesis, hormone physiology and disease resistance. In this study, the genetically stable yellow-green leaf mutant ygl16 was identified from mutated “Xinong 1B”. Compared with the wild type, the pigment concentration and photosynthetic capacity of the ygl16 decreased significantly. The ultrastructural observation showed that the distribution of thylakoid lamellae was irregular in ygl16 chloroplasts, and the grana and matrix lamellae were blurred and loose in varied degrees, and the chloroplast structure was disordered, while the osmiophilic corpuscles increased. The results of More >

Abstract There is a positive correlation between fertility and yield, and the decrease of fertility is bound to a greatly reduced crop yield. Male sterile mutants can be used in hybrid rice. Therefore, rice male sterility has an important value in research and application, and the study of related mutants is also very vital. The mutant ms10 (male sterile 10) reported in this study was induced by ethyl methane sulfonate (EMS) in the indica maintainer line Xinong 1B. There was no significant difference between the ms10 and wild type in the vegetative growth stage. However, in the reproductive… More >

Abstract Cowpea is one of the most important legume grains in the sub-Saharan region of Africa used for human consumption and animal feed, but its production is hampered by biotic and abiotic constraints raising the need to broaden its genetic basis. For this purpose, seeds of two cowpea varieties Melakh and Yacine were irradiated with 300 and 340 Gy of gamma-ray, respectively. The developed mutant populations were agromorphologically characterized from M5 to M7, while the genetic diversity of the latter was evaluated using 13 ISSR markers. Based on the agromorphological characterization, variation of flower color, pod… More >
