The combined role of dispersal and niche evolution in the diversification of Neotropical lizards

Ecology and Evolution, Volume 10, Issue 5, Page 2608-2625, March 2020., 2020
We integrated ecological and molecular data to investigate the relative roles of biogeographic events and niche evolution on the diversification of a lizard genus distributed in Neotropical rainforests and savannas. Our results suggest that dispersal and ecological divergence could have a more important role in Neotropical diversification than ...

Meiotic analysis of interspecific hybrids between Capsicum frutescens and Capsicum chinense [PDF]

Crop Breeding and Applied Biotechnology, 2017
The aim of this study was to observe the genetic relationship between C. frutescens (UENF 1636) and C. chinense (UENF 1785) based on the meiotic behavior, on the meiotic index, and on pollen viability of their F1 hybrids. For meiotic analysis and meiotic

Reactive oxygen species act as signaling molecules to control root hair initiation and tip growth

New Phytologist, Volume 247, Issue 5, Page 2042-2048, September 2025.
Summary Root hairs (RHs) increase the surface area of roots, facilitating nutrient and water uptake and plant anchorage. RHs form from root epidermal cells and elongate by polar tip growth. Reactive oxygen species (ROS) have recently been implicated as important signals that drive RH formation and elongation using both genetic and imaging approaches ...
