YlmG1 is localized exclusively to the chloroplast envelope membrane and is involved in preprotein translocation in Arabidopsis thaliana

FEBS Open Bio, EarlyView.
Cytosolically synthesized chloroplast preproteins are translocated across the outer and inner envelope membranes through translocons called TOC and TIC, respectively. In green algae and plants, the TIC core is composed of essential membrane proteins, Tic12, Tic20, and Tic214.

Perdas de nitrogênio por volatilização de amônia e resposta do arroz irrigado à aplicação de ureia tratada com o inibidor de urease NBPT Nitrogen losses by ammonia volatilization and lowland rice response to NBPT urease inhibitor-treated urea

Ciência Rural, 2010
A ureia é a principal fonte de nitrogênio (N) para o arroz irrigado, porém é bastante suscetível a perdas por volatilização de amônia. O uso do inibidor de urease N-(n-butil) triamida tiofosfórica (NBPT) pode minimizar esse problema, inibindo ...

Differential effects of ruminally protected amino acids on fattening of fallow deer in two culling periods

Animal, 2020
A well-balanced amino acid profile in the feedstuffs for livestock is essential to support adequate growth. This is well studied for monogastric species but still not well understood for ruminants and especially for the most unconventional species, like ...
