“…Many species of Conyza are also perennial rarely shrubs, growing to 1-2 m tall. The native area of the weed is warm temperate and tropical regions throughout the world (Paula et al, 2017). This weed has multi-stems near base and these stems are full of long white hairs.…”

“…This weed has multi-stems near base and these stems are full of long white hairs. Leaves are thin, narrow, stalkless and become further smaller towards the top of plant (Santos et al, 2014;Paula et al, 2017). Inflorescence is branched and nearly 35 cm long and produces pale yellow flowers in September-October on short, thickly hairy pedicels.…”

“…C. bonariensis caused 25.9% yield reduction soybean (Agostinetto et al, 2017). C. stricta has an invasive potential and thought in difficult to control due to resistance to herbicides (Paula et al, 2017). There is little research on C. stricta in Pakistan and elsewhere.…”

The new variety Betula pendula ‘Dalecarlica’ selected from Betula pendula, shows high ornamental values owing to its lobed leaf shape. In this study, to identify the genetic components of leaf shape formation, we performed bulked-segregant analysis (BSA) and molecular marker-based fine mapping to identify causal gene responsible for lobed leaves in B. pendula ‘Dalecarlica’. The most significant variations associated with leaf shape were identified within the gene BpPIN1 encoding a member of PIN-FORMED family, responsible for the auxin efflux carrier. We further confirmed the hypomethylation at the promoter region promoting the expression level of BpPIN1, which cause stronger and longer veins and lobed leaf shape in B. pendula ‘Dalecarlica’. These results indicated that DNA methylation at the BpPIN1 promoter region is associated with leaf shapes in Betula pendula. Our findings revealed an epigenetic mechanism of BpPIN1 in the regulation of leaf shape in birch, which could help in molecular breeding of ornamental traits.

As plantas daninhas são causa do encarecimento das lavouras, entre elas está Conyza spp, conhecida como buva. Marcadores moleculares vem sendo utilizados para complementar sua caracterização. A técnica AFLP (Amplified Fragment Length Polymorphism) é adaptada para diversas análises genéticas, fornecendo alta cobertura do genoma. Com objetivo de caracterizar molecularmente morfotipos de buva, foram coletadas 60 plantas da UENP – Bandeirantes/PR. A análise molecular com AFLP seguiu etapas de digestão, ligação de adaptadores, amplificação pré-seletiva e seletiva, utilizando combinação de seis pares de primers AFLP. Os fragmentos foram separados em gel de poliacrilamida 8% e corados com AgNo3. Dos 218 loci, 97 foram polimórficos sendo 53 específicos para um morfotipo e 44 para o outro. A matriz de distância genética, a porcentagem de locos polimórficos, diversidade gênica de Nei (1978), e a distância genética foram obtidas utilizando o programa TFPGA (Tools For Population Genetcs Analyses). Os resultados da AMOVA mostram que a variação entre as populações é de 85,18% e dentro das populações é de 14,82% indicando que os morfotipos sejam espécies diferentes. Através das análises moleculares e principais características morfológicas demonstrou se que os morfotipos são espécies distintas, o morfotipo A é Conyza sumatrensis e o morfotipo B Conyza bonariensis.
