Summary Begomovirus‐associated epidemics currently threaten tomato production worldwide due to the emergence of highly pathogenic virus species and proliferation a whitefly B biotype vector that is adapted tomato. To generate an efficient defence against begomovirus, we modulated activity immune receptor nuclear shuttle protein ( NSP )‐interacting kinase NIK ) in plants; virulence target begomovirus during infection. Mutation T474 within activation loop promoted constitutive ‐mediated...
The protein kinase (PK) superfamily is one of the largest superfamilies in plants and core regulator cellular signaling. Despite this substantial importance, kinomes sugarcane sorghum have not been profiled. Here, we identified profiled complete polyploid Saccharum spontaneum (Ssp) Sorghum bicolor (Sbi), a close diploid relative. Sbi kinome was composed 1,210 PKs; for Ssp, 2,919 PKs when disregarding duplications allelic copies, these were related to 1,345 representative gene models. Ssp...
Germination is a biological process that depends on adequate water supply to embryo development. Water deficit slows this and depending intensity extent of may cause seed death. Nevertheless, it has not yet been reported whether size influences physiological potential, or tolerance stress. This study aimed at assessing the effects size, as well stress germination seeds early soybean seedling The experiment was composed by 10 cultivars classified metallic screens with three sizes oval holes...
The Geminiviridae family encompasses a group of single-stranded DNA viruses with twinned and quasi-isometric virions, which infect wide range dicotyledonous monocotyledonous plants are responsible for significant economic losses worldwide. Geminiviruses divided into nine genera, according to their insect vector, host range, genome organization, phylogeny reconstruction. Using rolling-circle amplification approaches along high-throughput sequencing technologies, thousands full-length...
Physiological quality and vigor of the seeds comprise properties that determine a high level activity performance during germination seedling emergence, having direct relation with establishment stand crop. In this context, assessment development, including analysis seed reserves mobilization are reliable method to investigate physiological potential lots. preliminary study, aim was dynamics sample soybean commercial cultivars. By means length bioassay weight dry matter seeds, cotyledons,...
Anthracnose, caused by the hemibiotrophic fungus Colletotrichum lindemuthianum, is a damaging disease of common beans that can drastically reduce crop yield. The most effective strategy to manage anthracnose use resistant cultivars. There are many resistance loci have been identified, mapped and associated with markers in bean chromosomes. Leucine-rich repeat kinase receptor protein (LRR-RLK) family diverse group transmembrane receptors, which potentially recognizes pathogen-associated...
Abstract Asian soybean rust (ASR), cause by the fungal pathogen Phakopsora pachyrhizi , stands out as paramount menace to cultivation, resulting in staggering yield decreases that can surpass 90%. Despite extensive endeavors, development of cultivars endowed with comprehensive or enduring resistance against myriad pathotypes remains elusive, thereby underscoring imperative for pioneering improvement tactics. Fungal effectors, orchestrating infiltration and colonization hosts, constitute...
Abstract White mold, caused by the fungus Sclerotinia sclerotiorum (Lib.) de Bary, is a devastating disease affecting common bean ( Phaseolus vulgaris L.) production worldwide. Breeding for resistance to white mold challenging due its quantitative inheritance and intricate genetic mechanisms. This research aimed validate characterize physiological in pinto dry market class through greenhouse straw tests under controlled conditions field assessments natural environments. Classical trait locus...
Pear ( Pyrus spp.) is a temperate-climate fruit species that has gametophytic self-incompatibility. Cross-pollination among intercompatible cultivars can be useful in selecting for breeding programs. The objective of the present study was to evaluate effective fruiting from cross-pollination between hybrid pear and characterize tree S-alleles. Seven were evaluated: Cascatense, Centenária, D’água, Primorosa, Seleta, Tenra, Triunfo. Controlled crosses carried out two seasons consisted...
O objetivo deste trabalho foi determinar o fluxo gênico recíproco entre duas cultivares de soja, uma tolerante e outra sensível ao glifosato, além aplicar estimadores para a taxa fecundação cruzada na população número sementes híbridas progênie. experimento compôs-se quatro blocos com 40 fileiras 20 cada cultivar (CD217 CD219RR). No estádio R8, cinco fileiras, distantes 0, 5, 1, 2, 4 8 m da adjacente, foram colhidas, trilhadas analisadas quanto à ocorrência gênico. Como características...
O objetivo deste trabalho foi avaliar métodos para detecção de sementes soja tolerante ao glifosato e o fluxo gênico uma cultivar transgênica convencional, em Florestal Viçosa, MG. Para adequar método detecção, conduzido experimento comparativo entre cinco bioensaios, dos quais se destacou teste germinação substrato umedecido com solução do glifosato. instalado campo, no esquema quadrados concêntricos. No centro, plantada a (fonte pólen). À sua volta, semeada sensível (receptora estádio R8,...
O teste de comprimento plântulas possui vantagens significativas para a avaliação do vigor sementes. Além baixo custo, não há necessidade equipamentos sofisticados, nem recursos humanos altamente especializados e os resultados são obtidos rapidamente. Contudo, tem-se notado presença com hipocótilos grossos curtos na realização deste quando conduzido 20 sementes soja, o que pode interferir nos resultados. objetivo trabalho foi avaliar efeitos tamanho da amostra (20 10 sementes), diâmetro rolo...
The adoption of genetically modified soybean cultivars is increasing annually around the world, which indicates excellence these genotypes. For breeding, use such in a backcross program relies on ability to detect transgenic trait. germination test moistened substrate with glyphosate effective and low cost, however, wonders whether this non-destructive method check cultivars. objective study was apply bioassay for detection herbicide-tolerant seeds evaluate vegetative productive development...
Advances in genotyping technologies have transformed the way breeding programs manage their genetic resources. The identification of single nucleotide polymorphisms (SNPs) can improve understanding diversity maize (Zea mays) inbred lines and classification into heterotic groups, which is useful determining certain crosses to obtain hybrids with higher yield performance. 293 was investigated 5252 SNPs minor allele frequency (MAF)>5%. There an average 525 per chromosome. Polymorphism...

Abstract The PAM2 motif represents a binding site for poly (A) proteins (PABP), often associated with RNA metabolism regulation. PAM2-containing protein ERD15 stands out as critical regulator of diverse stress responses in plants. Despite the relevance motif, comprehensive analysis superfamily and ERD15-like subfamily plant kingdom is lacking.
