Hydrogen sulfide (H2S) is a natural toxicant in some aquatic environments that has diverse molecular targets. It binds to oxygen transport proteins, rendering them non-functional by reducing oxygen-binding affinity. Hence, organisms permane...
Genetic classification of Aegilops columnaris Zhuk. (2n=4x=28, UcUcXcXc) chromosomes based on FISH analysis and substitution patterns in common wheat × Ae. columnaris introgressive lines [0.03%]
基于FISH分析和普通小麦×Aegilops columnaris导入系替换模式的长柱山羊草（2n=4x=28，UcUcXcXc）染色体遗传分类研究
