    Genome-Wide Identification and Expression Profiling of the Shaker K+ Channel and HAK/KUP/KT Transporter Gene Families in Grape (Vitis vinifera L.)

    Han Lei1,#, Junlin Li2,#, Zhizhong Song1,3,*

    Phyton-International Journal of Experimental Botany, Vol.91, No.11, pp. 2519-2536, 2022, DOI:10.32604/phyton.2022.021268

    Abstract Potassium (K+) is an essential macronutrient for plants to maintain normal growth and development. Shaker-like K+ channels and HAK/KUP/KT transporters are critical components in the K+ acquisition and translocation. In this study, we identified 9 Shaker-like K+ channel (VvK) and 18 HAK/KUP/KT transporter (VvKUP) genes in grape, which were renamed according to their distributions in the genome and relative linear orders among the distinct chromosomes. Similar structure organizations were found within each group according to the exon/intron structure and protein motif analysis. Chromosomal distribution analysis showed that 9 VvK genes and 18 VvKUP genes were unevenly distributed on 7 or… More >

    Shuang Song1, Xiaomei Li2, Xin Wang1, Qi Zhou1, Yongping Li1, Xiaojing Wang1, Shoukun Dong1,*

    Phyton-International Journal of Experimental Botany, Vol.91, No.11, pp. 2475-2490, 2022, DOI:10.32604/phyton.2022.021090

    Abstract Soybean is an important legume food crop, and its seeds are rich in nutrients, providing humans and animals with edible oil and protein feed. However, soybean is sensitive to water requirements, and drought is an important factor limiting soybean yield and quality. This study used Heinong 84 (drought resistant variety) and Hefeng 46 (intermediate variety) as tested varieties planted in chernozem, albic, and black soils. The effects of drought stress on the activities of key enzymes in carbon metabolism and photosynthetic characteristics of soybean were studied during the flowering stage, most sensitive to water.

    Abstract In soil biota, higher and enduring concentration of heavy metals like cadmium (Cd) is hazardous and associated with great loss in growth, yield, and quality parameters of most of the crop plants. Recently, in-situ applications of eco-friendly stabilizing agents in the form of organic modifications have been utilized to mitigate the adverse effects of Cd-toxicity. This controlled experiment was laid down to appraise the imprints of various applied organic amendments namely poultry manure (PM), farmyard manure (FYM), and sugarcane press mud (PS) to immobilize Cd in polluted soil. Moreover, phytoavailability of Cd in wheat was also accessed under an alkaline… More >

    Phyton-International Journal of Experimental Botany, Vol.91, No.11, pp. 2439-2459, 2022, DOI:10.32604/phyton.2022.020100

    Abstract Identification of quantitative trait loci (QTLs) controlling yield and yield-related traits in rice was performed in the F2 mapping population derived from parental rice genotypes DHMAS and K343. A total of 30 QTLs governing nine different traits were identified using the composite interval mapping (CIM) method. Four QTLs were mapped for number of tillers per plant on chromosomes 1 (2 QTLs), 2 and 3; three QTLs for panicle number per plant on chromosomes 1 (2 QTLs) and 3; four QTLs for plant height on chromosomes 2, 4, 5 and 6; one QTL for spikelet density on chromosome 5; four QTLs… More >

    Identification and Characterization of a Novel Yellow Leaf Mutant yl1 in Rice

    Xiaofang Zeng1,#, Guangzheng Li1,#, Nu’an Liu2, Yan Li1, Jianrong Li1, Xiaozhen Huang1, Degang Zhao1,2,,*

    Phyton-International Journal of Experimental Botany, Vol.91, No.11, pp. 2419-2437, 2022, DOI:10.32604/phyton.2022.021199

    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 >

    How does FtsZ’s treadmilling help bacterial cells divide?

    XINXING YANG*, RUIJIAO LIU

    BIOCELL, Vol.46, No.11, pp. 2343-2351, 2022, DOI:10.32604/biocell.2022.022100

    Abstract Most bacteria assemble a ring-like macromolecular machinery scaffolded by the essential cytoskeletal protein FtsZ for cell division. Studies have broadly explored how FtsZ could polymerize at the correct place and time. Recently, the FtsZ-ring was found to exhibit dynamic treadmilling along the circumference of the division site, driven by GTP hydrolysis. This apparently directional motion of FtsZ seems to drive the movement of septal cell wall synthesis enzymes and to play an important role in modulating cell envelope constriction and septum morphogenesis. However, the relationship between FtsZ’s treadmilling dynamics and cell wall synthesis varies in different bacteria. More importantly, the… More >

    Es-SOX8 regulates the morphological changes of the sperm nucleus of Eriocheir sinensis by activating Es-BMP2 transcription

    KE JIA1, FU-QING TAN2, SHUANG-LI HAO1,*, WAN-XI YANG1,*

    BIOCELL, Vol.46, No.11, pp. 2399-2413, 2022, DOI:10.32604/biocell.2022.022015

    Abstract The SRY-related high mobility group (HMG) box (SOX) transcription factors participate in many physiological processes of animal growth, development, and reproduction and are related to spermatogenesis in many species. However, the relationship between SOX and spermatogenesis in Eriocheir sinensis is rarely reported. Here, we studied the role of Es-SOX8 in the spermatogenesis of E. sinensis and its possible regulation mechanism. Immunofluorescence results demonstrated Es-SOX8 signal in both cytoplasm and nucleus of spermatogonia, spermatocytes as well as spermatids, but not in mature spermatozoa. Hematoxylin and eosin staining showed a significant increase in the number of spermatozoa with abnormal nuclear morphology   … More >

    BIOCELL, Vol.46, No.11, pp. 2497-2506, 2022, DOI:10.32604/biocell.2022.021861

    Abstract The metabolic activity of the fruits continues even after harvest, which results in the loss of bioactive compounds, a decrease in the quality of the fruits, softening and browning, among other negative effects. The use of certain elements such as silicon can improve postharvest quality, since it is involved in the metabolic, physiological and structural activity of plants, moreover can increase the quality of the fruits. In addition, nanotechnology has had a positive impact on crop yield, nutritional value, fruit quality and can improve antioxidant activity. For these reasons, the use of beneficial elements such as silicon in the form… More >

    BIOCELL, Vol.46, No.11, pp. 2455-2463, 2022, DOI:10.32604/biocell.2022.021661

    Abstract Bone marrow mesenchymal stem cell (MSC)-based therapy is a novel candidate for heart repair. But ischemia-reperfusion injury leads to low viability of MSC. Dexmedetomidine (Dex) has been found to protect neurons against ischemia-reperfusion injury. It remains unknown if Dex could increase the viability of MSCs under ischemia. The present study is to observe the potential protective effect of Dex on MSCs under ischemia and its underlying mechanisms. Specific mRNAs related to myocardial ischemia in the GEO database were selected from the mRNA profiles assessed in a previous study using microarray. The most dysregulated mRNAs of the specific ones from the… More >

    CHANG CHEN1,#, LIMIN QIAO2,#, KAIJUN GUO1, YINGQIU WANG1, MENGYI YUAN3, BOFAN FU4, XIAOBO GAO3, HEMIN NI1, LONGFEI XIAO1,*, XIANGGUO WANG1,*

    BIOCELL, Vol.46, No.11, pp. 2415-2423, 2022, DOI:10.32604/biocell.2022.021510

    Abstract Endometritis affects the reproductive capacity of dairy cows and leads to serious economic losses in dairy farming. Clarification of the pathogenesis of endometritis is necessary to improve the reproductive efficiency of dairy cows. Exosomes and their miRNAs have been proven to play an important role in inflammatory regulation. Exosomal miR-218 is a differentially expressed miRNA found in endometrial epithelial cells (EECs) under endometrial inflammation. Therefore, we investigated the expression of miR-218 in the uterine tissue of dairy cows, lipopolysaccharide (LPS) treated EECs, exosomal vesicles, and regulation of exosomal miR-218 by targeting TGIF-2 inducible factor homology frame 2 (TGIF2)/transforming growth factor-beta… More >
