Novel alleles linked to brown rust resistance in sugarcane
Plant Pathology, 2022Abstract Sugarcane brown rust, caused by Puccinia melanocephala , is a severe foliar disease that occurs in almost all countries where sugarcane is grown. The main control strategy is the use of resistant cultivars.

Puccinia triticina (wheat brown rust).
2021Abstract Leaf rust seldom kills wheat, but it is capable of causing 35-50% yield loss in endemic areas on susceptible cultivars, where severity levels of 25-40% are reached at the tillering stage and 100% at the flowering stage. The disease causes more damage worldwide than other wheat rusts.

Silicon fertilisation decreases brown rust incidence in sugarcane
Crop Protection, 2013Abstract Few studies have focused on the effect that silicon fertilisation has on the incidence of brown rust in sugarcane, even though this crop is Si-accumulating and Si addition has been shown to have positive effects in other plant-pathosystems. The objective of this study was to quantify brown rust development in sugarcane after the addition of ...

Growth and photosynthesis in barley infected with brown rust
Physiological Plant Pathology, 1981Barley plants infected with brown rust at the first leaf stage showed reduced growth over the following 16 days. This could be accounted for entirely by reduced net photosynthesis of, and transport from, the infected leaf. Diseased leaves had reduced net photosynthesis, increased dark and photo-respiration and slightly decreased stomatal resistance.

Relationships between brown and false rusts and cowpea yields
Crop Protection, 1995Abstract Selected elite cowpea lines with different levels of resistance to brown rust (Uromyces vignae) and false rust (Synchytrium dolichi) were used to study the relationship between false and brown rusts and grain yield. Varying intensities of brown and false rust were obtained with different fungicide treatments in field experiments.

On light-sensitivity in germinating uredospores of wheat brown rust
Netherlands Journal of Plant Pathology, 1967Experiments consisted of three phases: spore production, spore storage and spore germination. Throughout the experiments temperature was near-optimal. In each phase various light and humidity treatments were given. The time at which a spore germinated was considered to be a stochastic variable.

Water relations of leaves of barley infected with brown rust
Physiological and Molecular Plant Pathology, 1991The water balance of brown rust ( Puccinia hordei ) infected barley seedlings was investigated. It was found that with the progression of the disease, the infected leaves lost their ability to maintain a favourable water status. This was attributed to tears in the cuticle, which occurred from day 5 after infection.

Histological responses in Hordeum chilense to brown and yellow rust fungi
Plant Pathology, 1992The histological reaction of 16 Hordeum chilense accessions to Puccinia recondila, P. hordei and P striiformis was investigated.

Mutations in wheat showing altered field resistance to yellow and brown rust
Genome, 2002Intensive screening of a small population of mutagenised wheat lines revealed a large number of lines with altered resistance to both yellow and brown rust. The parental cultivar Guardian has an intermediate level of adult plant resistance to this disease; mutants were therefore isolated that showed either enhanced resistance or enhanced susceptibility

Marker-trait association and epistasis for brown rust resistance in sugarcane
Euphytica, 2014Sugarcane brown rust, caused by Puccinia melanocephala, is one of the major sugarcane diseases. The detection of molecular markers associated to brown rust resistance and also of its epistatic interactions were investigated in a mapping population obtained by crossing the brown rust susceptible clone IACSP953018 and the resistant cultivar IACSP933046 ...
