The application of marker-assisted selection in coffee breeding programs accelerates the identification and concentration target alleles, being essential for developing cultivars resistant to multiple diseases. In this study, a population was developed from artificial crossings between Timor Hybrid Tupi Amarelo, with aim promoting pyramiding resistance genes main diseases pests Coffea arabica: leaf rust (CLR), berry disease (CBD), cercospora, miner. Resistance confirmed by nine molecular...
The biotrophic fungus Hemileia vastatrix causes coffee leaf rust (CLR), one of the most devastating diseases in Coffea arabica . Coffee, like other plants, has developed effective mechanisms to recognize and respond infections caused by pathogens. Plant resistance gene analogs (RGAs) have been identified certain plants as candidates for ( R ) genes or membrane receptors that activate genes. RGAs different possess conserved domains play specific roles fight against Despite importance RGAs,...
Two valid ant species, Camponotus rufipes and renggeri, have recently been the subject of a broad discussion with reference to taxa synonymization. Both species are quite common among Neotropical myrmecofauna share some unique traits, such as shape scape pilosity patterns tibiae scapes. A single morphological trait can help distinguish these species; however, only combination different approaches enlighten our view complex phylogenetic relationships prevailing in populations two taxa....
The biotrophic fungus Hemileia vastatrix is the pathogen responsible for coffee leaf rust, a devastating disease in several coffee-producing countries. Despite importance of studying interaction between Coffea and H. vastatrix, more comprehensive understanding mechanisms involved this pathosystem necessary. role eight candidate genes was analyzed aiming at identifying validating new important resistance their with vastatrix. These were identified most sources resistance, Híbrido de Timor...
Abstract The phytonematode Meloidogyne paranaensis is one of the main threats to coffee production. development Coffea arabica cultivars resistant this pathogen an urgent demand for growers. Progenies derived from wild germplasm Amphillo are considered potential sources resistance M. paranaensis, however, mechanisms involved in have not yet been elucidated. In present work, different progenies was studied and molecular markers associated with were identified. Through Genomic-Wide...
The biotrophic fungus Hemileia vastatrix is the pathogen responsible for causing coffee rust, a devastating disease in trees several coffee-producing countries. Despite importance of studying interaction between Coffea and H. vastatrix, it remains largely unexplored. Therefore, our study aimed to integrate genomic, transcriptomic, interatomic approaches enhance understanding genes biological processes involved this pathosystem. We conducted cloning, sequencing, functional annotation from...
