The world genetic community suffered an irrepara-
ble loss: one of the most renowned geneticists of Tajiki-
stan and the CIS countries, Academician of the Tajik
Academy of Sciences, Doctor of Biology, Professor
Pulat Dzhuraevich Usmanov died at 68 years of age
after a prolonged illness.
Usmanov was born on May 7, 1935 in the town of
Kanibadam, the former Tajik SSR. His whole career
was associated with the Tajik Academy of Sciences. He
graduated from the Tajik State University in 1959 and
passed a long way from the position of a senior labora-
tory assistant in the Institute of Botany to that of the
Head of the Department of Genetics in the Tajik Acad-
emy of Sciences.
Having received general biological education at the
university, from 1961 to 1965 Usmanov specialized in
genetics and cytogenetics in research institutes of the
Urals and the town of Obninsk under the guidance of
famous geneticists N.V. Timofeeff-Ressovsky, N.V. Luch-
nik, and L.S. Tsarapkin.
Communication with these prominent researchers
inﬂuenced Usmanov’s scientiﬁc interests and work in
plant genetics. Usmanov studied radiation genetics,
plant cytogenetics, and genetics of photosynthesis,
including the function of the photosynthetic system at
various levels: molecular, ontogenetic, population, and
biospherical. His well-known works focused on muta-
tion-dependent variation and biochemical genetics of
, genetics of cotton, and ecological genet-
ics. Usmanov collected numerous
and his collection was for a long time maintained at the
Siya-Kukh highland station. On the basis of this
collection, original genetic test systems were
constructed and used to evaluate the genetic conse-
quences of environmental pollution. Another widely
known series of Usmanov’s articles considers the effect
of ionizing radiation on the mutation process in natural
populations from the area affected by the
Chernobyl meltdown. In total, Usmanov published
approximately 250 works both in his country and
Usmanov gave considerable attention and energy to
teaching, which he believed to be one of the most
important duties of every scientists. For three decades
he lectured in universities and trained young research-
ers. Under his guidance, ten researchers prepared and
successfully defended candidate dissertations.
Organization of genetic research was another focus
of Usmanov’s activity. He was an active member of the
governing organs of the Vavilov Society of Geneticists
and Breeders and its autonomous section, the Tajik
Society of Geneticists and Breeders. Throughout the
years of research and teaching, Usmanov always
attended main genetic meetings, conferences, sympo-
sia, and seminars.
Being variously gifted, Usmanov left a rich photo-
graph collection, which highlights the live of prominent
biologists and includes portraits, sketches, and land-
scapes. Beautiful photographs taken by him were
included in numerous books, collections, and albums.
Many works of Pulat Dzhuraevich were carried out
in cooperation with his wife, Olga Vladimirovna
Usmanova. She was always his faithful friend, assis-
tant, and colleague. Their sons took other paths in life,
yet the family remained united and close-knit even
when the children grew up and became independent.
Pulat Dzhuraevich Usmanov’s name is forever put
into the annals of our (Soviet, Tajik, and Russian) sci-
ence as that of a gifted researcher and a trustworthy col-
