Diverged subpopulations in tropical Urochloa (Brachiaria) forage species indicate a role for facultative apomixis and varying ploidy in their population structure and evolution by Higgins, Janet, Tomaszewska, Paulina, Pellny, Till K., Castiblanco, Valheria, Arango, Jacobo, Tohme, Joseph M., Schwarzacher, Trude, Mitchell, Rowan A., Heslop-Harrison, J.S., Vega, Jose J. de

“…The subpopulation structure observed in the Urochloa sexual–apomictic multiploidy complexes supports geographical parthenogenesis, where the polyploid genotypes exploit the evolutionary advantage of apomixis, i.e. uniparental reproduction and clonality, to occupy extensive geographical areas.…”

Summary: creating systems innovation platforms for transformative pathways in circular economy by Sobratee‑Fajurally, Nafiisa, Nhamo, L., Mabhaudhi, Tafadzwanashe

“…More specifically, it seeks to demonstrate how tension arising between the dichotomy of short-term efficiency versus large-scale transition or mandated sector-specific achievements versus long-term systemic resilience outcomes can be accommodated if we can shift our perspective from seeing these as dichotomies to one where the evolutionary principle of complex systems is envisioned (Siegenfeld & Bar-Yam, 2020). …”

Estimates of genetic variances and relationship among traits associated with stem borer resistance in maize (Zea mays L.) by Oloyede-Kamiyo, Q., Ajala, S., Akoroda, M.O.

“…In the absenceof further resistance diversification, the long-term effectiveness of the single gene resistance is knownto be precarious, given the potential to be overcome by CMGs due to their fast-paced evolutionary rate.However, combining the quantitative with the qualitative type of resistance may ensure that this resis-tance gene continues to offer protection to cassava, a crop that is depended upon by millions of peoplein Africa against the devastating onslaught of CMGs.…”
