1:关于真菌基因组次级代谢分析,可以使用SMURF和AntiSMASH,基因组注释使用MAKER,基因与测使用AUGUSTUS并基于Aspergillus
oryzae物种的训练结果。拼接使用的是Velvet
Optimizer,基因功能注释使用的是interproscan.测序深度27x,N50 为
48,518。1,231
contigs。基因组大小为:31,415,732
bp。GC含量:48.24%
使用tRNAscan-SE与测tRNA.

2:关于真菌基因组的分析,在已知近源物种的基础上,可以分析结构变异(例如染色体重排等)

3:在真菌基因预测方面本文分别使用了Fgenesh(Penicillium
funiculosum 训练)与GeneMark-
ES(基于自身训练),基于预测是在大于1Kb的且经过masker重复序列的基础上进行的将两者结果整合。关于功能注释内容包括:nr\interproscan\Swiss-Prot/UniProtKB\GO\kegg(KAAS
)

4:这篇文章里关注了水平基因转移,组装完基因预测先是使用GeneMark
and TWINSCAN分别与测然后再合并,再合并genewise的结果(Genomic sequences
with 90% identity that spanned more than 80% of a protein were ex-
tended 500 bp up and downstream and passed to Gene-Wise to predict
gene models.
)假定基因的功能注释使用blast2go.假定蛋白的功能域和GO分析可以使用

5:细胞色素P450(cytochromeP450或CYP450,简称CYP450)为一类亚铁血红素—硫醇盐蛋白的超家族,它参与内源性物质和包括药物、环境化合物在内的外源性物质的代谢.网址:http://drnelson.uthsc.edu/P450seqs.dbs.html。使用blastp(e<10-5).(A
physical CYP gene cluster was de ned as three or more CYPs present
within a 100-kb sliding window of the genomic sequence or fewer
than 10 genes between CYPs a er they had been sorted into groups
along the chromosomes. If two adjacent clusters overlapped, they
were merged to form one larger cluster)

6:真菌基因组的大小范围:In
fungi, the diversity of genomes varies from 8.97 Mb to 177.57 Mb.

diversity of fungal genome[J]. Biological procedures online, 2015,

7:关于植物共生菌的微生物多样性研究,因为里面会参杂植物、叶绿体的序列,需要在数据分析之前排除掉(plastid
and
mitochondrial)。或者在分析完OTU后,只保留真菌(细菌)的那部分。对于测序文章中指出6万到-20万,所以建议客户做10万,对于土壤样本46.1%是植物的,5.4%是真菌,48%为分类。见文献:

8:关于真菌病毒基因的注释数据库为DFVF:

factors,http://sysbio.unl.edu/DFVF/index.php参考文献:

the Environment using Metagenomics: a Decade in Review
9:关于次级代谢分析可以使用SMURF(网页链接不可用)与anti-SMASH
http://antismash.secondarymetabolites.org,目前关于次级代谢的软件有很多,但是上面两款是分析结果是比较全面的。
