    Genome-Wide Characterization of the Cellulose Synthase Gene Superfamily in Tea Plants (Camellia sinensis)

    Qianqian Li1, Qi Zhao1,2,*, Xinzhuan Yao1, Baohui Zhang1, Litang Lu1,2,*

    Phyton-International Journal of Experimental Botany, Vol.91, No.10, pp. 2163-2189, 2022, DOI:10.32604/phyton.2022.021530

    Abstract The cellulose synthase gene superfamily, including Cellulose synthase A (CesA) and cellulose synthase-like (Csl) gene families, is responsible for the synthesis of cellulose and hemicellulose, respectively. The CesA/Csl genes are vital for abiotic stress resistance and shoot tenderness regulation of tea plants (Camellia sinensis). However, the CesA/Csl gene family has not been extensively studied in tea plants. Here, we identified 53 CsCesA/Csl genes in tea plants. These genes were grouped into five subfamilies (CsCesA, CsCslB, CsCslD, CsCslE, CsCslG) based on the phylogenetic relationships with Arabidopsis and rice. The analysis of chromosome distribution, gene structure, protein domain and motif revealed that… More >

    Nonprecsion (Standard) Psychosocial Interventions for the Treatment of Mental Disorders

    Alan E. Kazdin*

    International Journal of Mental Health Promotion, Vol.24, No.4, pp. 457-473, 2022, DOI:10.32604/ijmhp.2022.022522

    Abstract Advances in precision treatment promise to greatly improve the extent to which therapies for mental disorders are better matched to patient characteristics. At the same, we need to ensure that more readily disseminable and available nonprecison treatments are further developed as well. These treatments refer to standardized interventions that do not have to be individualized and are more readily available. Impetus for this call stems from the treatment gap, namely, the huge difference in the proportion of individuals who are in need of mental health services and who actually receive any form of treatment. The prevalence rates for mental disorders… More >
