The paper contains preliminary results of rust fungal research conducted during 2015-2018 years in Nuratau, Boysun and Turkistan mountain ranges in Uzbekistan. During our study, rusted and non-rusted specimens were collected and we identified 13 species of rust fungi and 18 host plant species from the study area. The rust species belong to 5 genera and 4 families. Among the studied taxa, Puccinia rhamni Kuprev. on Rhamnus coriaceae (Regel) Kom. is newly reported for rust mycobiota of Uzbekistan.

NEW RECORDS OF RUST FUNGI OF TREES AND SHRUBS FROM UZBEKISTAN

Abstract: The paper contains preliminary results of rust fungal research conducted during 2015-2018 years in Nuratau, Boysun and Turkistan mountain ranges in Uzbekistan. During our study, rusted and non-rusted specimens were collected and we identified 13 species of rust fungi and 18 host plant species from the study area. The rust species belong to 5 genera and 4 families. Among the studied taxa, Puccinia rhamni Kuprev. on Rhamnus coriaceae (Regel) Kom. is newly reported for rust mycobiota of Uzbekistan.

Keywords: Nuratau, Boysun and Turkistan mountain ranges, Rust fungi, Basidiomycota, Pucciniales, new records, host plants.

Introduction

Among the a lot of fungal pathogens of plant diseases, rust in paper bags and were deposited in Tashkent mycological

fungi are very widespread and often, under favorable condi- herbarium (TASM) of the Institute of Botany (IB). The main

tions can be cause severe damage to many herbaceous, shrub- method of identifying the species of fungi was light micros-

by and woody plants, which leads to decrease the productivity copy, carried out according to standard procedures. Measure-

of them, as well as to the loss of decorative qualities [1; 3]. ments were made from slide stained preparations observed

Currently, around 7,000 rust fungi from 168 genus dis- under the Motic BA 410 light microscope in the laboratory

tributed in the world, more than half of them belong to the of Mycology and algalogy of the IB. Species identification was

genus Puccinia [2; 4]. performed according to Kuprevich [4, 5-308], Ulyanischev

At the moment, more than 261 species of rust fungi have [5, 5-324], Ramazanova et al. [3, 17-190], Minkevicius [6,

been recorded on the territory of Uzbekistan. They are regis- 8-270], Azbukina [7, 1-615]. Fungal names are given in ac-

tered on 511 species of host plants belonging to 43 families cording with www.mycobank.org [8]. Host plants are given

of vascular plants [3; 5]. with www.theplantlist.org. [9].

Materials and methods Results

The material for the present study was samples of the 13 species of rust fungi (Pucciniales) of trees and shrubs

herbarium of affected plants harvested on the territory of were reported from Boysun, Nuratau and Turkiston mauntain

the Nuratau, Boysun and Turkistan mauntain ranges. Dur- ranges from 2015 to 2018. The rust species belong to 5 genera

ing the intensive study of rust fungi samples were collected and 4 families (Table 1). Among the rusts recorded, Gym-

from various woody and shruby host plants in 2015-2018 nosporangium (3 species), Phragmidium (4 species), Puccinia

from the study area. Samples were dried at room temperature (3 species), Melampsora (2 species), Tranzschelia (1 species).

From the facts in (Table 1), it can be seen that the largest number of species of rust fungi of tree and shrub species belongs to the genus Phragmidium, Gymnosporangium, Puccinia.

It is known, that rust fungi are found almost on all continents, almost everywhere, where vascular plants grow. The distribution of rust fungi in the families of vascular plants is uneven. Rust fungi were discovered on 18 species of vascular plants, belonging to 5 families and 11 genera. The host families with the greatest number of rust species were Rosaceae with 8 species (61.5%), Salicaceae with 2 species (15.4%) representing 75,9% of all rust species present in the study area (Tab. 2). The highest number of rust species is reported in the genus Rosa L.

Thus, in Nuratau, Boysun and Turkiston mauntain ranges on trees and shrubs were recorded 13 species of rust fungi. From them Puccinia rhamni is recorded as a new species for mycobiota of Uzbekistan and Rhamnuscoriaceae is recorded as a new host plant. In the analysis of rust fungi relationship with host plants, it is revealed that they parasitize on 18 species ofvascular plants belonging to 4 families. More than half to the rust species found in the area live on host species belonging to Rosaceae.

Herbarium materials are persisting in the mycological collection of the Institute of the Botany of the Academy of Sciences of Uzbekistan.
