从砍柴割草到“编写生命密码”——记基因组学家杨焕明

新华社深圳9月1日电 题:从砍柴割草到“编写生命密码”——记基因组学家杨焕明

新华社记者 周科、王晓丹

在世界上首次利用全基因组“霰弹法”策略对大型植物基因组进行测序,独立完成超级杂交水稻父本籼稻“9311”基因组的“工作框架图”;在抗击非典行动中研制了SARS的诊断用抗原、抗体和相关标记物,并在全球首个公布SARS诊断试剂……

他,就是中国科学院院士、深圳华大基因研究院研究员杨焕明,一名从砍柴割草、捕鱼捉虾到“编写生命密码”的基因组学达人。

  儿时经历成探索科学动力

出生于浙江省乐清市一个山村的杨焕明,小时候一放学就得去砍柴割草,每逢周日还得冒着被淹死的危险,到海边捉鱼蟹。右手一道几厘米长的刀疤,是他儿时翻山越岭辛苦劳作的见证。

“哪个农村孩子,不希望‘不劳而获’呢?”小时候的杨焕明,心中有个“拔苗助长”的梦想,他恨不得秧苗能一夜长成稻谷,谷子能像蚕豆那么大。

一次,杨焕明从邻居沾满泥巴的手中看到了一节莲藕,这种生长于淤泥之中、横切面巧妙排列数个小孔的植物,让他感觉到生物的神奇。“这是我第一次为神奇的大自然所造就的生物之美所感叹!”他说。

让杨焕明被科学力量所震惊的还有柴油机和农药。柴油机的出现,取代了龙骨水车,提高了父辈们灌溉农田的效率;农药的喷洒,不仅没能灭绝害虫,还污染了河田里的鱼虾。

正是这些经历,让杨焕明开始爱上自然,产生了探索科学世界的动力。

在几十年前的“上山下乡”期间,杨焕明在当地一家酿造厂总技术员的帮助下,阅读了大量生物教材,还学习了微生物的基本知识。当吃苦耐劳的杨焕明被乡亲们认为以后能做生产队长时,他心里想的却是:“我一定不会在这里一直待下去。”

1975年,杨焕明进入杭州大学生命科学院就读,自此,他正式踏进生物学的世界。

如今,杨焕明不仅走出了山村,还走向了世界,成了生命密码的破解者,在基因组学研究的国际舞台发声。

  “只有吃苦,才能懂得珍惜”

在杨焕明的少年朋友和青年工友的印象里,他永远是一个“读书狂”形象,书包里总是放着要看的书。至今,他仍然坚持每天看书、看文献,在很长一段时间内保持每天读30篇以上的文献资料。
