“…Interestingly, it was recently found that Bacillus sp. LC390B-stimulated the growth-promoting effect was disrupted in an Arabidopsis thaliana phyA/phyB double mutant,indicating that light perception through PHYA and PHYB is important for plant growth promotion by a beneficial bacterium (Garcia-Cardenas et al, 2023).However,to our knowledge,how light quality modulates root colonization of PGPR such as A21-4 remains unclear.…”

Effective colonization on plant roots is a prerequisite for plant growth promoting rhizobacterias (PGPR) to exert beneficial activities. However, how light modulates root colonization of PGPR remains unclear. Here, we found that high red/far red(R/FR) light promoted and low R/FR light inhibited the colonization of Serratia plymuthica A21-4 on tomato. Non-targeted metabolomic analysis of root exudates collected from different R/FR ratio treated tomato seedlings with A21-4 inoculation showed that 64 primary metabolites in high R/FR light-grown plants significantly increased compared with those determined for low R/FR light-grown plants. Among them, 7 amino acids, 1 organic acid and 1 sugar obviously induced the chemotaxis and biofilm formation of A21-4 compared to the control. Furthermore, exogenous addition of five artificial root exudate compontents (leucine, methionine, glutamine, 6-aminocaproic acid and melezitose) regained and further increased the colonization ability of A21-4 in tomato under low R/FR light and high R/FR light, respectively, indicating their involvement in high R/FR light-regulated the interaction of tomato root and A21-4. Taken together, our results, for the first time, clearly demonstrate that high R/FR light-induced root exudates play a key role in chemotaxis, biofilm formation and root colonization of A21-4, which can help promote the combined application of light supplementation and PGPR to facilitate crop growth and health in agricultural production.

“…Todos os gêneros bacterianos isolados no presente trabalho já foram anteriormente descritos como presentes na rizosfera de milho e apontados como potenciais promotores de crescimento de plantas a partir de testes fisiológicos realizados in vitro e in planta (García-Cárdenas et al, 2023;Deng et al, 2022;Massucato et al, 2022;Santos et al, 2022;Kafi et al, 2021;Olanrewaju et al, 2021;Rattanapolsan et al, 2021;Ali et al, 2020;Chukwuneme et al, 2020;Wahyudi et al, 2019;Tchakounté et al, 2018). Diversos estudos apontam um screening fisiológico in vitro como sendo uma metodologia eficiente para a seleção de BPCPs (Emami et al, 2019;Youseif, 2018;Toribio-Jiménez et al, 2017;Ahmad et al, 2008).…”
