Abstract: An updated analysis of the diversity of rust fungi in
Himachal Pradesh is provided herein as a product of field surveys, of
mycological analysis, and of all forms of published documentation and literature. The results of all forms of analysis revealed
that Himachal Pradesh has 167 species of rust fungi belonging to the class
Pucciniomycetes. The class is
represented by 11 families, 23 genera with 167 species. The Pucciniaceae (96 species) followed
by Phragmidiaceae (14 species) are the largest families of rust fungi
reported from the state. Rest of the
families were found associated with 1–10 species of rust fungi. The rust fungi (19 species) with uncertain
placement are placed in incertae sedis. The rust genera reported from Himachal Pradesh
so far are Aecidium, Chrysomyxa, Coleosporium, Frommea,
Gymnosporangium, Kuehneola, Kweilingia, Melampsora,
Monosporidium, Ochrospora, Peridermium, Phakopsora,

Introduction
Rust fungi are highly specialized obligate plant
parasites having several unique morphological and microscopic features. These fungi commonly appear as yellow orange
or brown powder on a variety of host plants and
plant parts. Unlike other plant
pathogens, rusts usually affect healthy and vigorously growing plants; the
infection is limited to plant parts, such as leaves, petioles, tender shoots,
stem, and fruits. The group is
considered as one of the most harmful plant pathogens in agriculture,
horticulture and forestry. These fungi
are of major concern because they act as limiting factors for the successful
cultivation, plantation and growth of agricultural crops and forestry plants. A wider diversity and broader host range is
exhibited by this fungal group and their infection is not only limited to
agricultural crops but also non-agricultural plants including medicinal herbs,
shrubs, trees, and even weeds. An
estimated 168 rust genera and approximately 7,000 species exist on various
plant hosts, more than half of which belong to the genus Puccinia (Mohanan
2010).
Rust fungi show unique systematic characteristics
among all fungal groups. A single
species may produce up to five morphologically and cytologically distinct
spore-producing structures, viz., spermagonia, aecia, uredinia, telia, and
basidia, in successive stages of reproduction during the infection
process. The presence of these successive
stages may vary from species to species.
To initiate and develop infection, rusts require an average temperature
up to 35°C along with 50–60 % relative humidity. The rust infected plants may appear stunted,
chlorotic (yellowed), or otherwise discoloured, whereas, disease symptoms
includes coloured pustules, witches brooms, stem canker, hypertrophy of the
affected tissues or formation of galls (Cummins & Hiratsuka 2003). Unlike
other fungi, rusts exhibit one of the most important characteristics of their
exceptionally high degree of host specificity.
Among all reported rust fungi, some are among
agriculture’s most destructive and devastating pathogens, causing diseases such
as wheat stem rust, wheat yellow (stripe) rust, Asian soybean rust, coffee rust
and many more. These rust fungi cause
annual crop losses in billions every year worldwide. This loss can be greater in developing world
where growers are not aware about diseases caused by rust fungi and often
cannot afford fungicides. Owing to their
economic importance, the rusts have been studied extensively in regular
mycological surveys in Himachal Pradesh, but no single-source compiled
literature is available. Therefore, this
study facilitates the access to scattered Himalayan literature with reference
to rust fungi to the students and plant pathologists of national and
international community.
Study area
Himachal Pradesh is one of the northern states of
India that lies between 30.377– 32.21 North and 75.74 – 79.07 East. It is a mountainous state with very high
mountains to grasslands in plain (Figure 1).
Great variations in elevation ranging from about 350m (1,148 ft) to
7,000m (22,966 ft) are found in the state.
The variations are also observed in the climatic conditions. Hot and sub-humid tropical conditions were
found in the southern tracts while, cold, alpine and glacial conditions in the
northern and eastern mountain ranges with more elevation. The variability in rainfall was observed in
the range of 1,500–3,000 mm. These
variations in geo-climatic conditions of the state lead to greater biodiversity
in the state. A total 66.52% of the area
is covered with very dense evergreen to deciduous forests types. While, alpine shrub and meadows are found distributed
in the west and northeastern Himalaya; alders, birches, rhododendrons, and
moist alpine shrubs are regional vegetation.
The plant pathogens including bacteria, fungi and viruses are also found
due to these changeable geographical and climatic conditions of the state which
are quite favourable for their growth and development.
Materials and methods
The information on rust fungi was gathered by
investigating the following data sources: (1) mycological survey conducted on
rust fungi from Himachal Pradesh during the years 2014 to 2018, and (2) all
forms of published documentation and literature (Bilgrami et al. 1991;
Jamaluddin et al. 2004). The names of
some taxon in the obtained data have been replaced by currently accepted names
as they were of out-of-date. The current
usage of names was checked using the Index Fungorum (http://www.indexfungorum.org/)
to adopt the generic and specific taxonomy in Species Fungorum (http://www.speciesfungorum.org/).
The plant samples found infected with rust fungi were
collected during a mycological survey of various localities of Himachal
Pradesh. Field observations of rust
fungi on host plants and their photographs were taken in natural conditions. Collected specimens were packed in paper bags
and taken to the laboratory for further analysis. A few disease samples were used for
morphological analysis of the rust fungi and the rest of the materials were
dried for future microscopic studies.
The air dried specimens were preserved in standard size herbarium packets
and deposited at the Abhilashi University Mycological Herbarium (AUMH).
The microscopic mounts were prepared from fresh
samples by brushing the rust powder into a drop of distilled water and
lactophenol on microscopic slides, which were covered with cover slip and
gently heated. The microscopic slides were analysed for spore dimensions like
size, shape and ornamentations.
Both macro- and micro-morphological characters
obtained from the laboratory were only used for taxonomic studies of the
collected fungi. The fungal specimens
were identified and their distribution records were checked by using standard
literature (Cummins & Hiratsuka 2003; Mukerji & Manoharachary 2010).
Illustrations are photographed under microscope equipped with digital camera.
Results
As per the results obtained in the present study and
from all sources of information, Himachal Pradesh has 167 species of rust fungi
belonging to 23 genera and 11 families (Table 1). The largest family is Pucciniaceae (95
species) followed by Phragmidiaceae (14 species). Other families were reported to have species
of rust fungi up to ten. However, 19
species of rust fungi with uncertain placement are placed in taxonomic
group incertae sedis. Aecidium, Chrysomyxa, Coleosporium, Frommea,
Gymnosporangium, Kuehneola, Kweilingia, Melampsora, Monosporidium,
Ochrospora, Peridermium, Phakopsora, Phragmidium, Pileolaria,
Puccinia, Pucciniastrum, Pucciniostele, Ravenelia, Skierka,
Uredinopsis, Uredo, Urocystis, and Uromyces
are the rust genera reported so far from Himachal Pradesh.
Present studies revealed that 170 plant species
belonging to 52 families were found infected with rust fungi throughout the
state. Thirty-five hosts of family
Poaceae were highest to be found infected with these fungi followed by
Ranunculaceae (16), Rosaceae (15), Asteraceae (11), Polygonaceae (7), Fabaceae,
Salicaceae, Acanthaceae & Lamicaeae (6 each), Pinnaceae & Apiaceae (5
each), Rubiaceae (4), Saxifragaceae, Cyperaceae & Euphorbiaceae (3 each),
and Berberidiaceae, Geraniaceae, Linaceae & Zinziberaceae (2 each). The rest of the plant species were reported
to be infected with a single rust fungus.
The area-wise results revealed that most of the rust fungi (about 127)
were reported from Shimla and nearby regions followed by Solan (22), Kullu
(18), Kangra (9), Chamba & Mandi (7 each), Lahul & Spiti (4), and
Kinnaur & Bilaspur (1 each).

Discussion
The present study provides the checklist of rust fungi
from Himachal Pradesh, a northwestern Himalayan State of India. A remarkable diversity of rust fungi have
been reported from the state which has an area of 55,673km2. The
state exhibits marked variations in climate and vegetation and so far in fungal
diversity. The available information
about rust fungi from the state is in general meager and there is much scope
for exploratory work on the taxonomy, diversity and ecological aspects of these
fungi. There are about 167 species, 23
genera belonging to 11 families recorded from this hilly Himalayan state, with
great variations in host infected (about 171 plant species belonging to 121
genera and 52 families). This
distinguished diversity of rust fungi may be due to the fact that rust fungi
tend to prefer humid habitats, which is one of the major characteristic
features of the state. Being obligate
parasites, rust fungi are associated with spreading and development of nutrient
plants and are found in many belts, both on herbaceous plants, and on trees and
shrubs.
After compilation of literature it is observed that
most of the rust fungi were reported from Shimla and nearby regions. Although, these fungi are also reported from
other districts of the state but the scope of exploration of these fungi and
their host range is still there.
Two checklists on two major rust genera namely, Puccinia
(Gautam & Avasthi 2016b) Uromyces (Gautam & Avasthi 2017a)
have recently been published from this hilly state. Two new species of rust fungi namely Puccinia
himachalensis (Gautam & Avasthi 2016a) and Skierka himalayensis
(Gautam & Avasthi 2017b) have been reported from the state which are new to
science. Whereas, Pileolaria
pistaciae (Gautam & Avasthi 2017b), Kweilingia divina (Gautam
& Avasthi 2018) are the new additions to the mycobiota of the state while, Puccinia
tiliaefolia (Gautam & Avasthi 2017c) has been rediscovered after 46 years
from India. During the literature survey
we did not come across any molecular studies conducted on rust fungi from the
state. As per greater phytodiversity of
the state, studies on the rust fungi are inadequate and there is vast scope to
conduct studies and fill the data gaps.
Molecular studies of rust fungi are still required besides morphological
taxonomy, which will not only help in revision and reassessment of the existing
fungal species, but also to find their correct taxonomic position. The knowledge generated by the work is of
immense utility as it is a key to revealing the diversity and ecology of rust
fungi from Himachal Pradesh Himalaya.
