“…A pentatricopeptide repeat (PPR) domain candidate gene was found in the vicinity of SNP ss715645486. PPR domains have been implicated in an increase of biomass in a study of Paulownia trees ( Cao et al, 2020 ), and are also implicated in drought stress tolerance ( Jiang et al, 2015 ). The three tandem duplicate genes of 2-alkenal reductase in the vicinity of SNP ss715649390 are also implicated in increased biomass and improved drought tolerance in a study of transgenic tobacco plants ( Xi et al, 2015 ).…”

Root rot is a major constraint to snap bean (Phaseolus vulgaris) production in the United States and around the world. Genetic resistance is needed to effectively control root rot disease because cultural control methods are ineffective, and the pathogen will be present at the end of one season of production on previously clean land. A diversity panel of 149 snap bean pure lines was evaluated for resistance to Fusarium root rot in Oregon. Morphological traits potentially associated with root rot resistance, such as aboveground biomass, adventitious roots, taproot diameter, basal root diameter, deepest root angle, shallowest root angle, root angle average, root angle difference, and root angle geometric mean were evaluated and correlated to disease severity. A genome wide association study (GWAS) using the Fixed and random model Circulating Probability Unification (FarmCPU) statistical method, identified five associated single nucleotide polymorphisms (SNPs) for disease severity and two SNPs for biomass. The SNPs were found on Pv03, Pv07, Pv08, Pv10, and Pv11. One candidate gene for disease reaction near a SNP on Pv03 codes for a peroxidase, and two candidates associated with biomass SNPs were a 2-alkenal reductase gene cluster on Pv10 and a Pentatricopeptide repeat domain on Pv11. Bean lines utilized in the study were ranked by genomic estimated breeding values (GEBV) for disease severity, biomass, and the root architecture traits, and the observed and predicted values had high to moderate correlations. Cross validation of genomic predictions showed slightly lower correlational accuracy. Bean lines with the highest GEBV were among the most resistant, but did not necessarily rank at the very top numerically. This study provides information on the relationship of root architecture traits to root rot disease reaction. Snap bean lines with genetic merit for genomic selection were identified and may be utilized in future breeding efforts.

“…Atualmente espécies de Paulownia são encontradas por toda Ásia, Estados Unidos, Europa e Austrália. Pesquisadores já obtiveram avanços em estudos com a P. fortunei principalmente em relação ao seu melhoramento genético (Cao et al, 2020) e aspectos medicinais, como a extração de substâncias antioxidantes e anti-inflamatórias de flores, folhas e pecíolos (Zhang et al, 2020a;Zhang et al, 2020b;Rodríguez-Seoane et al, 2021;Rodríguez-Seoane et al, 2022). Além disso, também já foram descritas as suas características silviculturais e de crescimento (Criscuoli et al, 2022) bem como estudado as propriedades energéticas, químicas e morfológicas da madeira e das fibras sugerindo sua aptidão para produção de celulose e biocombustível sólido (Ashori;Nourbakhsh, 2009;Lopez et al, 2010;Lopez et al, 2012).…”

A espécie Paulownia fortunei, originária da China, vem despertando interesse da indústria devido ao seu rápido crescimento, curta rotação e boa adaptabilidade a condições climáticas adversas, sendo apontada como uma alternativa potencial para implementação de povoamentos florestais no Brasil. O estudo teve como objetivo avaliar as propriedades físicas e mecânicas da madeira de Paulownia fortunei em crescimento no Estado de Santa Catarina - Brasil, visando determinar o seu potencial aos 4 anos de idade como fonte de matéria-prima para a produção de produtos sólidos. Para a caracterização física, as condições do ensaio foram definidas de acordo com a norma ASTM D- 143 (1995) e para mecânica utilizou-se as normas COPANT 30: 1-006 (1972), COPANT 30: 1-007 (1971), COPANT 30: 1-009 (1971) e NBR 7190 (2022). Os resultados mostraram que a madeira de Paulownia fortunei apresenta densidade básica classificada como leve, com estabilidade dimensional intermediária e baixa resistência mecânica. Com base nessas propriedades, a espécie Paulownia fortunei em curtas rotações apresenta potencial para diversos usos, principalmente para produção de pequenos objetos de madeira e aplicações em que a baixa densidade seja a característica de interesse, sendo uma opção viável em aplicações não estruturais ou situações que não requerem resistência a esforços excessivos.
