UVR8 interacts with de novo DNA methyltransferase and suppresses DNA methylation in Arabidopsis
DNA methylation Light responses Plant signalling
2023/12/11
DNA methylation is an important epigenetic gene regulatory mechanism conserved in eukaryotes. Emerging evidence shows DNA methylation alterations in response to environmental cues. However, the mechan...
Harmonizing Forest Conservation Policies with Essential Biodiversity Variables Incorporating Remote Sensing and Environmental DNA Technologies
environmental DNA essential biodiversity variables forest conservation policies indicators remote sensing biodiversity products

It remains difficult to compare the state of conservation of forests of different nations. Essential Biodiversity Variables (EBVs) are a set of variables designed as a framework for harmonizing biodiv...
Extrachromosomal circular DNA: A neglected nucleic acid molecule in plants
eccDNA eccDNA sequencing Transposable elements Environmental adaptation
2023/11/16
Throughout the years, most plant genomic studies were focused on nuclear chromosomes. Extrachromosomal circular DNA (eccDNA) has largely been neglected for decades since its discovery in 1965. While i...
专家提议建立青藏高原雪豹DNA条形码 加速雪豹保护
青藏高原 雪豹 DNA条形码
2021/12/16
“未来,针对雪豹的野生种群还要做一些遗传多样性评估,遗传多样性评估对恢复种群有很大的作用,确定雪豹的指纹或者DNA条形码后,从野外毛发中就可以检测在这个区域里面大概有多少只雪豹。”11日,省部共建三江源生态与高原农牧业国家重点实验室常务副主任祁得林教授表示。

The maintenance of genome integrity over cell divisions is critical for plant development and the correct transmission of genetic information to the progeny. A key factor involved in this process is t...
项目应用DNA条形码技术对天女木兰的分子遗传分类进行研究,对不同来源天女木兰的条形码序列进行差异分析,考察不同生境样本间的亲缘关系、进化特点及其种群遗传多样性等信息,从分子水平对天女木兰的分类学地位进行修正,为天女木兰濒危机制及解濒研究提供参考。
随着全球气候变化的影响及人类活动的加剧,特别是热带经济作物如橡胶等的大面积种植,西双版纳作为我国生物多样性最丰富的地区之一,目前面临严重的威胁。DNA条形码能够利用一小段DNA序列快速进行物种鉴定,为生物多样性保护提供了一个极为有效的可靠途径。
