Uromycladium is a genus of rust fungi in the family Pileolariaceae. It was circumscribed by mycologist Daniel McAlpine in 1905. [1] The genus was established by McAlpine for rusts on Acacia (Fabaceae, subfamily Mimosoideae) with teliospores that clustered at the top of a pedicel. [1] [2]

Contents

The genus contains at least 11 species. Some of these species infect plants in the family Mimosoideae including Acacia , Paraserianthes and Falcataria . [2] Most species are considered to be specific to only one host species of plant, such as Uromycladium simplex on Acacia pycnantha [3] and Uromycladium falcatarium on Falcataria moluccana . [2] Uromycladium tepperianum , on the other hand, has almost 100 known hosts including plants from several tribes of Mimosoideae. [4] However, research suggests that this species may comprise several unrecognized taxa with narrower host ranges. [2] [5]

Ecology

The rust fungi in the genus Uromycladium typically form enlarged galls at the end of actively growing plant tissues. These galls can be a significant disease limiting the growth and survival of trees planted for commercial tree plantations and agroforestry. [7] The acacia gall rust fungus species Uromycladium tepperianum has been introduced to South Africa as a biological control on the invasive Australian shrub Acacia saligna . [8]

The galls of Uromycladium tepperianum have been reported to be used by moths in the families Gracillariidae, Tortricidae, Tineidae, Pyralidae, and Stathmopodidae as food sources and domatium for their larvae in Australia. [9] Specifically in the family Gracillariidae the species Polysoma eumetalla and Conopomorpha heliopla are found feeding on the surface of various species of acacia rust galls. Erechthias mystacinella and Opogona comptella moth larvae from the family Tineidae have been reported to live and feed on the inside of Uromycladium tepperianum galls.

Mimosoideae Subfamily of legumes

The Mimosoideae are a clade of trees, herbs, lianas, and shrubs in the pea family (Fabaceae) that mostly grow in tropical and subtropical climates. They are typically characterized by having radially symmetric flowers, with petals that are twice divided (valvate) in bud and with numerous showy, prominent stamens. The clade comprises about 40 genera and 2,500 species.

<i>Albizia</i> Genus of flowering plants in the legume family Fabaceae

Albizia is a genus of more than 160 species of mostly fast-growing subtropical and tropical trees and shrubs in the subfamily Mimosoideae of the family Fabaceae. The genus is pantropical, occurring in Asia, Africa, Madagascar, America and Australia, but mostly in the Old World tropics. In some locations, some species are considered weeds.

Botanical name Scientific name for a plant, alga or fungus

A botanical name is a formal scientific name conforming to the International Code of Nomenclature for algae, fungi, and plants (ICN) and, if it concerns a plant cultigen, the additional cultivar or Group epithets must conform to the International Code of Nomenclature for Cultivated Plants (ICNCP). The code of nomenclature covers "all organisms traditionally treated as algae, fungi, or plants, whether fossil or non-fossil, including blue-green algae (Cyanobacteria), chytrids, oomycetes, slime moulds and photosynthetic protists with their taxonomically related non-photosynthetic groups ."

<i>Acacia pycnantha</i> Golden wattle, a tree of the family Fabaceae native to southeastern Australia

Acacia pycnantha, most commonly known as the golden wattle, is a tree of the family Fabaceae native to southeastern Australia. It grows to a height of 8 m (26 ft) and has phyllodes instead of true leaves. Sickle-shaped, these are between 9 and 15 cm long, and 1–3.5 cm wide. The profuse fragrant, golden flowers appear in late winter and spring, followed by long seed pods. Plants are cross-pollinated by several species of honeyeater and thornbill, which visit nectaries on the phyllodes and brush against flowers, transferring pollen between them. An understorey plant in eucalyptus forest, it is found from southern New South Wales and the Australian Capital Territory, through Victoria and into southeastern South Australia.

In botany, the correct name according to the International Code of Nomenclature for algae, fungi, and plants (ICN) is the one and only botanical name that is to be used for a particular taxon, when that taxon has a particular circumscription, position and rank. Determining whether a name is correct is a complex procedure. The name must be validly published, a process which is defined in no less than 16 Articles of the ICN. It must also be "legitimate", which imposes some further requirements. If there are two or more legitimate names for the same taxon, then the correct name is the one which has priority, i.e. it was published earliest, although names may be conserved if they have been very widely used. Validly published names other than the correct name are called synonyms. Since taxonomists may disagree as to the circumscription, position or rank of a taxon, there can be more than one correct name for a particular plant. These may also be called synonyms.

<i>Acacia saligna</i> Species of plant in the family Fabaceae native to Australia

Acacia saligna, commonly known by various names including coojong, golden wreath wattle, orange wattle, blue-leafed wattle, Western Australian golden wattle, and, in Africa, Port Jackson willow, is a small tree in the family Fabaceae. Native to Australia, it is widely distributed throughout the south west corner of Western Australia, extending north as far as the Murchison River, and east to Israelite Bay. The Noongar peoples know the tree as Cujong.

<i>Acacia</i> Genus of plants

Acacia, commonly known as the wattles or acacias, is a large genus of shrubs and trees in the subfamily Mimosoideae of the pea family Fabaceae. Initially, it comprised a group of plant species native to Africa and Australasia, but it has now been limited to contain only the Australasian species. The genus name is New Latin, borrowed from the Greek ἀκακία, a term used by Dioscorides for a preparation extracted from the leaves and fruit pods of Vachellia nilotica, the original type of the genus. In his Pinax (1623), Gaspard Bauhin mentioned the Greek ἀκακία from Dioscorides as the origin of the Latin name.

<i>Paraserianthes lophantha</i> Species of legume

Paraserianthes lophantha, the Cape Leeuwin wattle, Cape wattle, crested wattle or plume albizia, is a fast-growing wattle with creamy-yellow, bottlebrush like flowers. It is a small tree that occurs naturally along the southwest coast of Western Australia, from Fremantle to King George Sound. It was first spread beyond southwest Australia by Baron Ferdinand von Mueller, who gave packets of P. lophantha seeds to early explorers under the assumption that if they planted the seeds at their campsites, the trees would indicate the routes they travelled.

<i>Erechthias mystacinella</i> Species of moth

Erechthias mystacinella, the curve-winged apple moth, is a moth of the family Tineidae. It is found in the Australian Capital Territory, Tasmania and Victoria.

<i>Falcataria</i> Genus of legumes

Falcataria is a genus of flowering plants in the family Fabaceae. It belongs to the monophyletic Mimosoid clade in the subfamily Caesalpinioideae. The genus has three species previously classified in the Falcataria section of the genus Paraserianthes by I.C. Neilsen. The distribution of these closely related species within the genus Falcataria links the wet tropics of north-east Australia to New Guinea, the Moluccas, Bismarck Archipelago, and the Solomon Islands east of Wallace's line similar to other plant taxa from the region.

<i>Paraserianthes</i> Genus of legumes

Paraserianthes is a genus of flowering plants in the family Fabaceae. It belongs to the mimosoid clade of the subfamily Caesalpinioideae.

<i>Vachellia</i> Genus of legumes

Vachellia is a genus of flowering plants in the legume family, Fabaceae, commonly known as thorn trees or acacias. It belongs to the subfamily Mimosoideae. Its species were considered members of genus Acacia until 2009. Vachellia can be distinguished from other acacias by its capitate inflorescences and spinescent stipules. Before discovery of the New World, Europeans in the Mediterranean region were familiar with several species of Vachellia, which they knew as sources of medicine, and had names for them that they inherited from the Greeks and Romans.

Conopomorpha heliopla is a moth of the family Gracillariidae. It is known from the Australian states of Tasmania, Queensland and Western Australia.

<i>Acacia pubescens</i> Species of legume

Acacia pubescens, also known as the downy wattle, is a species of wattle found in the Sydney Basin in eastern New South Wales. The downy wattle is classified as vulnerable; much of its habitat has vanished with the growth of the city of Sydney.

<i>Trichilogaster</i> Genus of wasps

Trichilogaster is a small genus of chalcid wasps in the family Pteromalidae, subfamily Ormocerinae. With one described exception, they all are Australian species that are gall-formers on Australian species of Acacia. The exception is an Arabian species. Apart from its ecological interest, the genus is of practical importance because some of its members are successful biocontrol agents in South Africa at least, where T. acaciaelongifoliae and T. signiventris have been established successfully to control invasive Australian Acacia species, notably Acacia longifolia and Acacia pycnantha.

Falcataria moluccana, commonly known as the Moluccan albizia, is a species of fast-growing tree in the family Fabaceae. It is native to the Maluku Islands, New Guinea Island, the Bismarck Archipelago, and the Solomon Islands. It is cultivated for timber throughout South Asian and Southeast Asian countries. This tree is considered to be invasive in Hawaii, American Samoa and several other island nations in the Pacific and Indian Oceans. It is about 30m tall tree in nature with a massive trunk and an open crown.

Uromycladium falcatarium is a species of rust fungus in the genus Uromycladium. It was circumscribed by mycologists Doungsa-ard, McTaggart & Shivasin in 2015.

<i>Uromycladium tepperianum</i> Species of fungus

Uromycladium tepperianum is a rust fungus that infects over 100 species of Acacia and related genera including Paraserianthes in Australia, south-east Asia, the south Pacific and New Zealand. The acacia gall rust fungus species Uromycladium tepperianum has been introduced to South Africa as a biological control on the invasive Australian shrub Acacia saligna.

Daniel McAlpine was a Scottish-born Australian mycologist known for his research in plant pathology. He wrote several publications on plant disease in many crops and other plants. McAlpine was a lecturer in biology at the University of Melbourne from 1884, and, with his appointment to the Victorian Department of Agriculture from 1890 to 1911, became the British Empire's first professional plant pathologist.
