Monitoring air pollution is related to the life quality and health of the people.In this study,we present concentrations of the heavy metals(e.g.cadmium(Cd),chromium(Cr),copper(Cu),nickel(Ni),lead(Pb)
Nitrogen is an essential element to all life forms,and its availability in environments is strongly dependent on nitrification.Ammonia oxidation,the crucial step of nitrification,is carried out by amm
桦木属(Betula L.)大约有65 个种和亚种,广泛分布于北半球,具有重要的生态价值和经济价值.由于广泛的自然杂交、多倍化及形态性状变异及趋同进化,该属种间进化关系尚未解决.高通量测序技术,如RADseq,可以产生成千上万个标记,有望解决复杂类群的进化关系.在本研究中,我们对桦木属开发了RAD标记,以欧洲垂枝桦(B.pendula)全基因组序列作为参考,通过比对获得大量长度在300bp 以上的
Replication factor C(RFC)is a conserved eukaryotic complex consisting of RFC1/2/3/4/5.It plays important roles in DNA replication and the cell cycle in yeast and fruit fly.However,it is not very clear
Auxin is critical in diverse developmental processes,such as the maintenance of shoot and root meristems.AUXIN RESPONSE FACTORs(ARF)are required for controlling the expression of auxin-responsive gene
Calmodulin(CaM),a multifunctional Ca2+sensor,mediates multiple reactions involved in plant growth and environmental stress regulation.In this study,we found that AtCaM4 plays a negative role in freezi
Nα-terminal acetylation catalysed by N-terminal acetyltransferases(Nats)is among the most common protein post-translation modifications in eukaryotes.A typical low IAA phenotype mutant ckrc3(CK induce
