HorizontalTransferofSupernumeraryChromosomesinFungi
Several species of filamentous fungi contain so-called dispensable or supernumerary chromosomes. These chromosomes are dispensable for the fungus to survive, but may carry genes required for specialized functions, such as infection of a host plant. It has been shown that at least some dispensable chromosomes are able to transfer horizontally (i.e., in the absence of a sexual cycle) from one fungal strain to......阅读全文

GALNT14基因突变与药物因子介绍
该基因编码一种高尔基蛋白，是多肽n-乙酰半乳糖氨基转移酶（ppgalnac-ts）蛋白家族的成员。这些酶催化n-乙酰-d-半乳糖胺（galnac）转移到目标肽丝氨酸和苏氨酸上的羟基。编码的蛋白质已经被证明可以将galnac转移到像粘蛋白这样的大蛋白上。这种基因的改变可能在癌症的进展和对化疗的反应中起

大自然的鬼斧神工：蝴蝶也是“转基因”
来自法国巴伦西亚大学和图伦大学的研究小组发现，来自于寄生蜂的基因存在于许多种蝴蝶的基因组中。这些基因通过一种寄生蜂相关的病毒，从而水平转移到这些蝴蝶的基因组中。似乎这些来自寄生蜂的基因已经被蝴蝶基因组“驯化”，并可能被用来发挥作用，来保护蝴蝶抵抗他致病病毒。这些研究结果，发表在《PLoS Gen
