Puccinia Graminis
Stem rust, also known as cereal rust, black rust, red rust or red dust, is caused by the fungus ''Puccinia graminis'', which causes significant disease in cereal crops. Crop species that are affected by the disease include bread wheat, durum wheat, barley and triticale. These diseases have affected cereal farming throughout history. The annual recurrence of stem rust of wheat in North Indian plains was discovered by K. C. Mehta. Since the 1950s, wheat strains bred to be resistant to stem rust have become available. Fungicides effective against stem rust are available as well. In 1999 a new, more virulent race of stem rust was identified against which most current wheat strains show no resistance. The race was named TTKSK (e.g. isolate Ug99). An epidemic of stem rust on wheat caused by race TTKSK spread across Africa, Asia and the Middle East, causing major concern due to the large numbers of people dependent on wheat for sustenance, thus threatening global food security.

Puccinia Recondita
''Puccinia recondita'' is a fungus species and plant pathogen belonging to the order of Pucciniales and family Pucciniaceae. Distribution This fungal species occurs worldwide. Biology It is a heteroecious fungus, macrocyclic, and has five distinct life-stages of development: teliospores, basidiospores, and urediniospores on cereal hosts, and pycniospores and aeciospores on the alternative plant hosts. Host These fungi are endoparasites plant pathogens mainly infecting species in the families of Balsaminaceae, Boraginaceae, Hydrophyllaceae, Ranunculaceae and Poaceae (especially wheat and rye). ''Puccinia recondita'' was also found to cause 'brown rust' in wheat and triticale (hybrid of wheat and rye). Symptoms of infestation are yellowish to brown spots and pustules on the leaf surfaces of the host plants. Brown rust is the most widespread and prevalent disease of wheat in South America, and is the most important wheat disease in Mexico. It was originally found on the leave ...

Rust (fungus)
Rusts are fungal plant pathogens of the order Pucciniales (previously known as Uredinales) causing plant fungal diseases. An estimated 168 rust genera and approximately 7,000 species, more than half of which belong to the genus ''Puccinia'', are currently accepted. Rust fungi are highly specialized plant pathogens with several unique features. Taken as a group, rust fungi are diverse and affect many kinds of plants. However, each species has a range of hosts and cannot be transmitted to non-host plants. In addition, most rust fungi cannot be microbial culture, grown easily in pure culture. Most species of rust fungi are able to Heteroecious, infect two different plant hosts in different stages of their life cycle, and may produce up to five Morphology (biology), morphologically and cytologically distinct spore-producing structures viz., spermogonia, aecia, uredinium, uredinia, Telium, telia, and basidia in successive stages of reproduction. Each spore type is very host-specific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wheat Yellow Rust
Wheat yellow rust (''Puccinia striiformis'' f.sp. ''tritici''), also known as wheat stripe rust, is one of the three major wheat Rust (fungus), rust diseases, along with Stem rust, stem rust of wheat (''Puccinia graminis'' f.sp. tritici) and Leaf rust (barley), leaf rust (''Puccinia triticina'' f.sp. tritici). History As R.P. Singh, J. Huerta-Espino, and A.P. Roelfs say in their 2002 comprehensive review of literature on the wheat rusts for UN FAO: Although Gadd first described stripe rust of wheat in 1777, it was not until 1896 that Eriksson and Henning (1896) showed that stripe rust resulted from a separate pathogen, which they named ''P. glumarum''. In 1953, Hylander et al. (1953) revived the name ''P. striiformis''. A stripe rust outbreak in northwest Syria contributed to the beginning of the Syrian civil war, Syrian Civil War by increasing food prices.

Puccinia Sessilis
''Puccinia sessilis'' is a fungal species and plant pathogen, which is also known as arum rust or ramsons rust. It commonly infects ''Arum maculatum'' and ''Allium ursinum'' causing yellow to orange circular patches on leaves. On the underside of the leaves, it produces raised orange aecia commonly covered in spores. It is common in Eurasia in the spring. It was originally found on the leaves of ''Iris versicolor'' in New York, USA. Other plant species affected by this rust include ''Convallaria majalis'', ''Dactylorhiza fuchsii'', '' Dactylorhiza incarnata'', ''Dactylorhiza majalis'', ''Gymnadenia conopsea'', ''Neottia ovata'', '' Paris quadrifolia'' and ''Phalaris arundinacea''. A specialised form, ''Puccinia sessilis'' f.sp.

Wheat Leaf Rust
Wheat leaf rust (''Puccinia triticina'') is a fungal disease that affects wheat, barley, rye stems, leaves and grains. In temperate zones it is destructive on winter wheat because the pathogen overwinters. Infections can lead up to 20% yield loss. The pathogen is a '' Puccinia'' rust fungus. It is the most prevalent of all the wheat rust diseases, occurring in most wheat-growing regions. It causes serious epidemics in North America, Mexico and South America and is a devastating seasonal disease in India. ''P. triticina'' is heteroecious, requiring two distinct hosts (alternate hosts). Host resistance Plant breeders have tried to improve yield quantities in crops like wheat from the beginning of agriculture. From the 20th century, breeding for resistance against disease proved to be as important for total wheat production as breeding for increase in yield. The use of a single resistance gene against various pests and diseases plays a major role in resistance breeding ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Puccinia Asparagi
''Puccinia asparagi'' is the causative agent of asparagus rust. It is an autoecious fungus, meaning that all stages of its life cycle – pycniospores, aeciospores, and teliospores – all develop upon the same host plant . Rust diseases are among the most destructive plant diseases, known to cause famine following destruction of grains, vegetables, and legumes. Asparagus rust occurs wherever the plant is grown and attacks asparagus plants during and after the cutting season. Asparagus spears are usually harvested before extensive rust symptoms appear. Symptoms are first noticeable on the growing shoots in early summer as light green, oval lesions, followed by tan blister spots and black, protruding blisters later in the season. The lesions are symptoms of ''Puccinia asparagi'' during early spring, mid-summer and later summer to fall, respectively. Severe rust infections stunt or kill young asparagus shoots, causing foliage to fall prematurely, and reduce the ability of the pl ...
