A Repertoire of Major Genes From Crop Wild Relatives for Breeding Disease‐Resistant Wheat, Rice, Maize, Soybean and Cotton Crops

Plant Breeding, EarlyView.
ABSTRACT Global food demand is predicted to rise anywhere from 59% to 98% by 2050 because of increasing population. However, the continued depletion of natural resources and increasing biotic and abiotic stresses will continue to pose significant threats to global food security in coming years.

Sensibilidade de populações de Phakopsora pachyrhizi ao fungicida protioconazol

Summa Phytopathologica, 2020
RESUMO A redução na eficiência de fungicidas sintéticos está associada a seleção de indivíduos que apresentam alterações genéticas que conferem resistência aos ingredientes ativos. A sinalização de variações na frequência de indivíduos resistentes nas populações de fungos pode ser quantificada através da concentração efetiva 50 (CE50).

Probing protein sequences as sources for encrypted antimicrobial peptides [PDF]

, 2012
Starting from the premise that a wealth of potentially biologically active peptides may lurk within proteins, we describe here a methodology to identify putative antimicrobial peptides encrypted in protein sequences.

New Legume Hosts of Phakopsora pachyrhizi Based on Greenhouse Evaluations [PDF]

Plant Disease, 2008
Phakopsora pachyrhizi, the causal organism of soybean rust, was first found in the continental United States in 2004 and has been found on soybean, kudzu, Florida beggarweed, and three Phaseolus species in the field. The pathogen has been reported to occur on more than 90 legume species worldwide and it is likely to infect native and introduced legume

Quantitative Resistance to Quinone Outside Inhibitor (QoI) Fungicides in Puccinia horiana Through the Combination of Seven Distinct Substitutions in Cytochrome b

Plant Pathology, Volume 75, Issue 1, January/February 2026.
Puccinia horiana, the causal agent of chrysanthemum white rust, has developed quantitative resistance to QoI fungicides through one to four substitutions, selected from F90I, N256S, Y257N, L275F, F278L, M295V or L299F in cytochrome b (Cytb). ABSTRACT Quinone outside inhibitors (QoIs) are a major class of agricultural fungicides.

Selection strategies of segregant soybean populations for resistance to Asian rust. [PDF]

, 2017
The objective of this work was to identify the best selection strategies for the more promising parental combinations to obtain lines with good resistance to soybean Asian rust (Phakopsora pachyrhizi). Two experiments were carried out in the field during

Advances on molecular studies of the interaction soybean - Asian rust. [PDF]

, 2012
: Effective management practices are essential for controlling rust outbreaks. The main control method used is the application of fungicides, which increases substantially the cost of production and is harmful to the environment.

Combinatorially Selected Peptides for Protection of Soybean Against Phakopsora pachyrhizi [PDF]

Phytopathology®, 2010
Phakopsora pachyrhizi, the fungal pathogen that causes Asian soybean rust, has the potential to cause significant losses in soybean yield in many production regions of the United States. Germplasm with durable, single-gene resistance is lacking, and control of rust depends on timely application of fungicides.
