Beschreibungen/Notizen

• The present study aimed to explore the effects of foliar application of a leonardite-based product on sugar beet ( L.) plants grown in the field. The approach concerned the evaluation of the community compositional structure of plant endophytic bacteria through a metabarcoding approach, the expression level of a gene panel related to hormonal metabolism and signaling, and the main sugar beet productivity traits. Results indicated that plants treated with leonardite (dosage of 2,000 ml ha , dilution 1:125, 4 mg C l ) compared with untreated ones had a significant increase ( < 0.05) in (i) the abundance of spp., recognized to be an endophyte bacterial genus with plant growth-promoting activity; (ii) the expression level of gene, coding for auxin transport proteins; and (iii) sugar yield. This study represents a step forward to advance our understanding of the changes induced by leonardite-based biostimulant in sugar beet.
