Hepatocellular carcinoma (HCC) is a worldwide malignancy with high morbidity and mortality. In this study, ubiquitin conjugating enzyme E2I ( UBE2I ), a small ubiquitin-like modifier E2 enzyme reportedly expressed in tumors, was examined for its potential effects in HCC. Bioinformatics analysis was performed based on HCCDB, TIMER, and Kaplan-Meier plotter databases to explore the clinical implications in HCC. An siRNA kit was used to downregulate UBE2I, and in vitro experiments-including migration, invasion and proliferation assays-were performed to examine UBE2I expression in HCC. Western blot (WB) was used to determine whether downregulated UBE2I expression influenced the prognosis of HCC via autophagy pathways. Finally, RNA-sequencing was performed to explore candidate molecular mechanisms underlying the effect of UBE2I. Bioinformatics analysis including stratification by alcohol ingestion and hepatitis status in HCC showed that highly expressed UBE2I was not only correlated with poor prognosis, but was also associated with immune infiltrates. In vitro experiments showed that high expression of UBE2I was associated with increased migration, invasion and proliferation of HCC cells. WB results indicated that downregulated expression of UBE2I was associated with higher levels of autophagy-related proteins including LC3A/B, Beclin-1 and ATG16L1. Moreover, RNA-sequencing results suggested that UBE2I was involved in hepatocarcinogenesis, non-alcohol fatty liver disease, steatohepatitis, liver fibrosis, inflammation, hepatoblastoma, tumor angiogenesis, type 2 mellitus diabetes, biliary tract disease and other diseases. We conclude that oncogene UBE2I is associated with poor prognosis of HCC via autophagy pathways and may be involved in hepatocarcinogenesis, tumor angiogenesis, non-alcohol fatty liver disease and inflammation., Competing Interests: None., (AJCR Copyright © 2020.)

Common wild rice (Oryza rufipogon Griff.) is the ancestor of cultivated rice (O. sativa L.), which has a greater genetic diversity and important traits that remain to be employed in cultivated rice. In this study, a set of introgression lines (BC4F5 and/or BC4F6) carrying various introgressed segments from common wild rice, collected from Dongxiang county, Jiangxi Province, China, in the background of an Indica (O. sativa L. ssp. indica) cultivar, Guichao 2, was used. A total of 12 drought-related quantitative trait loci (QTL) were identified by investigating drought tolerance of introgression lines under 30% PEG treatment at the young seedlings stage. Of these QTLs, the alleles of 4 QTLs on chromosome 2, 6 and 12 from Dongxiang common wild rice were responsible for increased drought tolerance of the introgression lines. In particular, a QTL qSDT12-2, near RM17 on chromosome 12, was consistently detected in different replications, and expressed stably under PEG stress throughout the study. It was also found that the QTLs located on different chromosomes might express at different stages.

A MYC (Myelocytomatosis) transcription factor gene, OsMYC, was cloned in rice (Oryza sativa L.). The putative protein of the OsMYC gene has a typical DNA binding domain: basic/helix-loop-helix (bHLH) motif at the C-terminus. Its nucleocide sequnce has 78%, 48%, 46% identity with that of the AtMYC2, MYC7E and PG1 genes, respectively. The identity of deduced amino acid between OsMYC and AtMYC2, MYG7E and PG1 is 95%, 84%, and 77% in the bHLH domain, and that is 81%, 54% and 52% in the N-terminus conserved region. The identity is 100% in the nuclear localization signal between them. Phylogenetic comparisons revealed that the OsMYC protein was related to the Arabidopsis AtMYC2, Zea MYC7E and Phaseolus vulgaris PG1. OsMYC gene was expressed at high level in stem, but low level in leaf and root and can be induced by ABA and Fe3+, which is similar to the expression pattern of MYC7E and RAP1 genes. Thus, this gene is a new member of the rice MYC family.

An advanced backcross population (BC3F2), derived from the cross between Yuanjiang common wild rice as the donor parent and Teqing as recurrent parent, was used to map QTLs controlling the number of vascular bundle and panicle-related traits from Yuanjiang common wild rice. Seven QTLs controlling the number of large vascular bundles in peduncle were detected on chromosome 1, 2, 3, 4, 7 and 10. Five QTLs for the number of small vascular bundles in peduncle were mapped on chromosome 1, 2, 3, 4 and 8. A total of 15 QTLs for the number of primary and secondary rachis branches and spikelets per panicle were identified on all chromosomes except chromosome 11 and 12. Most of alleles derived from O. rufipogon Griff. showed negative effect that reduced significantly vascular bundle, rachis branches and spikelets per panicle, suggesting that during the evolution from common wild rice to cultivated rice, favorable alleles were retained while removed undesirable ones. Most of QTLs controlling vascular bundle, rachis branches and spikelets per panicle showed cluster form or close linkage on chromosomes. The directions of their additive effects were consistent, which explained the genetic basis of significant correlation of their phenotypic characters. All the information suggested parallel evolution relationship among these traits.

An advanced backcross strategy was used to identify quantitative trait loci (QTLs) associated with plant height and days to heading in the BC3F2 population derived from an accession of common wild rice (Oryza rufipogon Griff.) from Yuanjiang in Yunnan Province of China, as the donor, and an elite Indica cultivar "Teqing", as the recipient. Based on analyses of 116 SSR markers distributed throughout the rice genome and by using single-point analysis, four putative QTLs derived from O. rufipogon were detected for plant height on chromosome 1, and 6 QTLs for days to heading on chromosome 1, 3, 7, 8 and 11. All Alleles of QTLs for plant height from O. rufipogon could increase plant height of the backcross population. One QTL near RM104 on chromosome 1, explaining 27% and 28% of phenotypic variance and additive value reached 26.24 cm and 26.28 cm respectively in Beijing and Hefei, was detected. The location of this QTL is corresponding to sd-1. One QTL near the marker RM25 on chromosome 1, explaining 13% and 15% of phenotypic variance was identified. The additive value of this QTL reached 4.60 days and 3.65 days respectively in Beijing and Hefei, and the allele from O. rufipogon could delay the backcross population's days to heading.

In this paper, allelic variation and genetic diversity among geographies and growth habit types were studied by using 223 accessions of common wild rice primary core collection in Guangxi Province, with 34 SSR primers locating on 12 chromosomes of rice and 19 phenotypic traits. In the results, 24.91 alleles were detected per locus on average with a range from 7 to 48. Compared to the cultivated rice, the wild rice showed more allelic variations. The ratio of heterozygote of SSR locus was 32.01% on average, and it's range was 1.35% 81.31%. The frequency of heterozygote of SSR locus in Oryza rufipogon Griff was much higher than in Oryza sativa L. The geographical distribution of genetic diversity measured by SSR markers was not completely accordant with that by phenotypic traits. At DNA level, more wild rice individuals and higher genetic diversity were included within the area covering north latitude 22 degrees - 23 degrees and 23 degrees - 24 degrees (comprising Longan, Fusui, Yongning, Xiangzhou, Laibin, Xuanwu, Yulin and Guigang county), which formed the center of genetic diversity. But the center of genetic diversity at the phenotypic level located within north latitude 21 degrees - 22 degrees and 22 degrees - 23 degrees. Among the four growth habit types, the genetic diversity from high to low was found respectively in prostrate type, sloping type, slighting type, and erect type at both DNA and phenotypic levels.

Transgenic lines (GC-1) carrying a senescence-inhibition cheimeric gene, IPT (isopentenyl transferase) gene, CBB23, a isogenic lines carrying Xa23 gene for resistance to bacterial blight, and Hexi15, a commercial cultivar showing high resistance to blast disease, were used as donors to pyramid IPT gene and Xa23 by marker-assisted selection (MAS). Seventeen BC1F1 plants pyramiding Xa23 gene and IPT genes were obtained from three multi-cross combinations. Then, the plants carrying Xa23 and IPT genes were crossed with parental lines of two-line hybrid rice, such as 9311, E32, Pei' ai 64S and W9834S. The progenies were backcrossed the acceptor parents. A total of 17 plants carrying Xa23 and IPT genes were detected by PCR, disease resistance identification and analysis of CTK contents of in the four combinations of "(9311///Hexi15/CBB23// GC-1) x 9311", "(E32///Hexi15/CBB23//GC-1) x E32", "(Pei'ai 64S///Hexi15/CBB23//GC-1) x Pei' ai 64S" and "(GC-1/CBB23//W9834S/Hexi15) x W9834S". These plants showed resistance to blast disease by inoculating test using 21 the lines of Pyricularia grisea from Northern China. Six plants of BC2F1 pyramiding Xa23 and IPT genes were further obtained in the combinations of "[(9311///Hexi15/CBB23//GC-1) x 9311] x 9311", "[(E32///Hexi15/CBB23//GC-1) x E32] x E32". After backcrossed and self-crossed 1 approximately 2nd, the plants pyramiding Xa23 and IPT genes can be used in the program of hybrid rice breeding.
