Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：A family of Monge-Ampère type operators converging to sigma_k, and their Minkowski problems
sigma_k汇聚 蒙日安培型 算子家族 闵可夫斯基问题
2023/4/17
We introduced a new family of translation invariant geometric measures arising from Integral Geometry of convex bodies. These measures are related to a family of new Monge-Ampère type operators conver...

When it comes to graphene, it appears that superconductivity runs in the family.
Genome-wide identification of NF-YA gene family in cotton and the positive role of GhNF-YA10 and GhNF-YA23 in salt tolerance
全基因组分析 雷蒙德氏棉 亚洲棉 海岛棉 陆地棉
2024/5/17
本研究基于全基因组分析，在雷蒙德氏棉、亚洲棉、海岛棉和陆地棉基因组中分别鉴定得到16、16、31和29个NF-YA基因。通过进化树分析将NF-YA基因分为4个亚组。结构分析表明NF-YA基因在棉属进化过程中相对保守。荧光定量显示GhNF-YAs可能通过ABA和 MeJA的调控通路响应盐和干旱。VIGS沉默GhNF-YA10和GhNF-YA23的表达，能显著降低棉花对盐的抗性，表明这两个基...
Systematical characterization of YUCCA gene family in five cotton species, and potential functions of YUCCA22 gene in drought resistance of cotton
棉花 YUC基因家族 生长素合成
2024/5/17
生长素在植物的正常生长发育中起着至关重要的作用。TAA/YUCCA基因家族编码色氨酸氨基转移酶（tryptophan aminotransferase），是生长素合成的关键酶。然而，棉花中YUCCA（YUC）基因家族尚未见报道。为了揭示YUC基因在棉花中的功能，我们系统地鉴定了五个棉种中的YUC基因家族，包括成员分析、特征描述、基因组内复制和共线关系。转录组学分析表明，GhYUCs参与了棉花的非生...
2021年8月14日，中国科学院北京基因组研究所（国家生物信息中心）国家基因组科学数据中心（CNCB-NGDC）在国际学术期刊Genomics，Proteomics & Bioinformatics在线发表题为“The Genome Sequence Archive Family: Toward Explosive Data Growth and Diverse Data Types”的文章，GS...
Sloths, which once roamed the Americas, ranged from tiny, cat-sized animals that lived in trees to massive ground sloths that may have weighed up to six tons. The only species we know today are two-to...
Crabs, lobsters and shrimp now have a family tree dating 500 million years（图）
Crabs lobsters shrimp family tree dating 500 million years

Polypterids are weird and puzzling African fish that have perplexed biologists since they were discovered during Napoleon's expedition to Egypt in the late 1700s.Often called living fossils, these eel...
Since the mid-1990s, when the first planet around another sun-like star was discovered, astronomers have been amassing what is now a large collection of exoplanets—nearly 3,500 have been confirmed so ...
