The cell state hypothesis like a “Mendel’s law”in plant tissue and cell culture

1996年我应邀到韩国做“组织培养中的细胞状态调控”的报告,美籍韩裔科学家Ok Young Lee-Stadelmann博士(对我人生有重要影响的学术导师之一)帮我做翻译,她向听报告的师生们介绍说“这是组织培养中的孟德尔定律”。在此,我把恩师称之为“组织培养中的孟德尔定律”以英文的形式介绍给大家。

Key issues and the solutions in plant tissue and cell culture

There are two critical issues in plant tissue and cell culture aiming at expressing totipotency of cell, one is the initiation of cell division and another is the differentiation of regenerated plant from callus after long-term culture. The genotypes that is easy to culture usually is easy to initiate cell division and induce plant differentiation. [...]

挖掘农业的多功能性满足和创造人类不断增长的需求

对于发展工业的空间不大或不具备优势的地区,在保障粮食和基本农产品安全供给的基础上,应拓展农业的多功能性,开创以农业为源头的“农源型”产业。如何发展这种产业?早期可侧重在“产品型”、“参与型”两种类型或模式上实现突破。传统观念的物质世界总是有限的,而创意是无限的,要注意用创意扩展、放大物质世界。

细胞状态观点的提出及其生命科学意义

The Origination of Cell State Hypothesis and Its Significance to Life Science (link>>) 王海波提出的细胞状态观点及相应的调控方法,使组织与细胞培养找到了自身的规律,突破了“不可预见”、“无法推理”的局限。组织及细胞培养面对的主要问题有两个,一个是“衰老”,另一个是“癌变”。他寻找组织和细胞培养机理的道路就是围绕解决这两个要害问题展开的。他的发现不仅找到了组织及细胞培养的一般规律,而且对揭示衰老与癌变的机理以及对衰老与癌变的防控也非常有意义。为了便于浏览,本网站要求作者在前面发表的FLASH版本基础上做了调整,以中英文分开的方式发表。FLASH版本依然保留,以方便下载和打印。欢迎各相关研究人员点击和点评。

Wheat research in HAAFS

There are 12 research institutes specialising in different areas of agriculture research in HAAFS. Three institutes are directly involved in wheat research namely Institute of dryland Farming, Institute of Food and Oil Crops and Institute of Genetics and Physiology. 6th, May, 2012, Shijiazhuang, China Wheat research in HAAFS Haibo Wang Deputy President of Hebei Academy [...]

More issues need to be considered in molecular breeding of wheat

A variety can not be a real pure line as one genotype in practice with traditional methods. The trans-gene and the gene introgressed via MAS are facing a serious challenge of background constraints. The gene of a Mendelian factor is much complicated than the gene of a DNA fragment. From a DNA fragment to a [...]

再论小麦分子育种需注意的问题

去年5月24-26日,笔者在北京举行的首次中澳小麦遗传与分子育种研讨会上,做了题为“小麦分子育种应注意的几个问题”的报告。其中谈到:1)理论上经过多代自交可获得纯系,但现实操作中却不可能实现,一般一个品种不是一个基因型。由传统做法创造的近等基因系不是真正的近等基因系,要想获得真正的近等基因系,所用的轮回亲本需经过单倍体加倍。2)转基因、分子标记选择导入的目标基因的功能,未必能如育种者所期望的那样表现出来,认识“基因的社会学原理”很重要。3)孟德尔因子所表示的基因远比DNA序列表示的基因复杂,从DNA序列到性状,有很多构成性状表达的元素在分子遗传学中没有覆盖到。

小麦分子育种需注意的几个问题

植物转基因中心王海波主任应邀参加了于2010年5月24-26日举行的“2010年中-澳小麦遗传与分子育种双边研讨会”,并做了题为“小麦分子育种应注意的几个问题”的报告。本文为王海波研究员所做报告的中文摘要,英文读者请点击链接>>阅读英文摘要。同时,王海波研究员也真诚欢迎相关研究人员点评。

Problems need to be considered in molecular breeding of wheat

With the development of molecular genetics, crop modification became more exact and precise. Some problems ignored in traditional genetics and breeding in the past have been emerged. The prestige of molecular breeding will be greatly affected if not paying attention to these issues.
