Genome-wide identification,characterization,and expression analysis of aluminum-activated malate transporter genes(ALMTs)in Gossypium hirsutum L.

Aluminum-activated malate transporters(ALMT)are widely involved in plant growth and metabolic processes,including adaptation to acid soils,guard cell regulation,anion homeostasis,and seed development.Although ALMT genes have been identified in Arabidopsis,wheat,barley,and Lotus japonicus,little is known about its presence in Gossypium hirsutum L.In this study,ALMT gene recognition in diploid and tetraploid cotton were done using bioinformatics analysis that examined correlation between homology and evolution.Differentially regulated ALMT genetic profile in G.hirsutum was examined,using RNA sequencing and qRT-PCR,during six fiber developmental time-points,namely 5 d,7 d,10 d,15 d,20 d,and 25 d.We detected 36 ALMT genes in G.hirsutum,which were subsequently annotated and divided into seven sub-categories.Among these ALMT genes,34 had uneven distribution across 14/26 chromosomes.Conserved domains and gene structure analysis indicated that ALMT genes were highly conserved and composed of exons and introns.The GhALMT gene expression profile at different DPA(days post anthesis)in different varieties of G.hirsutum is indicative of a crucial role of ALMT genes in fiber development in G.hirsutum.This study provides basis for advancements in the cloning and functional enhancements of ALMT genes in enhancing fiber development and augmenting high quality crop production.

Research Progress of HPV L1 Capsid Protein in Prediction of Cervical Lesions

Cervical cancer is one of the most common malignant gynecological tumors and has the second highest incidence of all malignancies in females.Chronic and persistent infection with High Risk Human Papillomavirus(HR-HPV)is the main cause of cervical cancer.There is a distinct lack of methodology by which to determine whether cervical epithelial dysplasia is cancerous following HPV infection.HPV L1 capsid protein is a major structural protein of human papillomavirus(HPV),and it is the main target of the local cellular immune response aiming to combat human papillomavirus after HPV infection within cervical cells.Greater understanding of HPV L1 capsid protein and its association with cervical cytology,histopathology,patient age and human papillomavirus viral load has the potential to contribute toward improved the diagnosis and management of cervical cancer,providing useful information for gynecological clinicians in the hope of improving patient treatment and quality of life.This article reviews the predictive utility of HPV L1 capsid protein for cervical lesions.
