Populus pruinosa is a species of flowering plant in the family Salicaceae, native to Central Asia, Afghanistan, and Xinjiang in China.{{cite POWO |id=776822-1 |title=Populus pruinosa Schrenk |access-date=25 July 2023 }} A halophytic tree usually {{cvt|10|m}} tall, but occasionally reaching {{cvt|20|m}}, it is often found growing in basins.{{cite web |url=http://www.efloras.org/florataxon.aspx?flora_id=2&taxon_id=200005695 |title=灰胡杨 hui hu yang |author= |date=2023 |website=Flora of China |publisher=efloras.org |access-date=25 July 2023 }}{{cite journal |title=The draft genome sequence of a desert tree Populus pruinosa |year=2017 |last1=Yang |first1=Wenlu |last2=Wang |first2=Kun |last3=Zhang |first3=Jian |last4=Ma |first4=Jianchao |last5=Liu |first5=Jianquan |last6=Ma |first6=Tao |journal=GigaScience |volume=6 |issue=9 |pages=1–7 |doi=10.1093/gigascience/gix075 |pmid=28938721 |pmc=5603765 }} Its bark is grayish-yellow, its branchlets and young sprouts are densely tomentulose and gray in color, and its leaves are tomentulose and grayish-blue. The genome of this species has been sequenced revealing that duplicated genes and the expansion of certain gene families in Populus pruinosa contributed to adaptation to extreme desert environments characterized by high salinity and drought.{{Cite journal |last1=Sun |first1=Jianhao |last2=Xu |first2=Jindong |last3=Qiu |first3=Chen |last4=Zhai |first4=Juntuan |last5=Zhang |first5=Shanhe |last6=Zhang |first6=Xiao |last7=Wu |first7=Zhihua |last8=Li |first8=Zhijun |date=2024-03-07 |title=The chromosome-scale genome and population genomics reveal the adaptative evolution of Populus pruinosa to desertification environment |url=https://academic.oup.com/hr/article/11/3/uhae034/7601711 |journal=Horticulture Research |volume=11 |issue=3 |pages=uhae034 |doi=10.1093/hr/uhae034 |issn=2662-6810 |pmc=10967694 |pmid=38544549}}
