Polar recruitment of RLD by LAZY1-like protein during gravity signaling in root branch angle control
Nature Communications, 2020 In many plant species, roots maintain specific growth angles relative to the direction of gravity, known as gravitropic set point angles (GSAs). These contribute to the efficient acquisition of water and nutrients.

Running of the spectral index and inflationary dynamics of F(R) gravity
Physics Letters B, 2022 In this work we shall provide a model-independent general calculation of the running of the spectral index for vacuum F(R) gravities. We shall exploit the functional form of the spectral index and of the tensor-to-scalar ratio in order to present a ...
