“…Gln, an N transporter and NH 3 carrier, plays a vital role in C/N metabolism, cellular homeostasis and biomass accumulation [ 25 ]. A few pieces of research have been implemented to study the effect of exogenous Gln on plant regeneration efficiency [ 32 , 33 , 34 ], biomass accumulation [ 22 , 35 ], biochemical constituents [ 36 , 37 ] and gene expression [ 27 ]. Although the widespread effects of Gln on plant growth and development have been disclosed, the underlying mechanism of exogenous Gln in regulating plant growth remains elusive.…”

Exogenous Gln as a single N source has been shown to exert similar roles to the inorganic N in poplar ‘Nanlin895′ in terms of growth performance, yet the underlying molecular mechanism remains unclear. Herein, transcriptome analyses of both shoots (L) and roots (R) of poplar ‘Nanlin895’ fertilized with Gln (G) or the inorganic N (control, C) were performed. Compared with the control, 3109 differentially expressed genes (DEGs) and 5071 DEGs were detected in the GL and GR libraries, respectively. In the shoots, Gln treatment resulted in downregulation of a large number of ribosomal genes but significant induction of many starch and sucrose metabolism genes, demonstrating that poplars tend to distribute more energy to sugar metabolism rather than ribosome biosynthesis when fertilized with Gln-N. By contrast, in the roots, most of the DEGs were annotated to carbon metabolism, glycolysis/gluconeogenesis and phenylpropanoid biosynthesis, suggesting that apart from N metabolism, exogenous Gln has an important role in regulating the redistribution of carbon resources and secondary metabolites. Therefore, it can be proposed that the promotion impact of Gln on poplar growth and photosynthesis may result from the improvement of both carbon and N allocation, accompanied by an efficient energy switch for growth and stress responses.

“…Asparagine, cysteine, citrulline, and L-glutamine were tested for the in vitro rooting of CAB-6P (Prunus cerasus L.) and Gisela 6 (P. canescens × P. cerasus) cherry rootstocks, using four concentrations (0; 0.5; 1 and 2 mg L-1) combined with 2 mg L-1 of indole-3-butyric acid. CAB-6P presented a higher number of roots compared to Gisela 6, highlighting the cysteine and L-glutamine amino acids at a concentration of 0.5 mg L-1 (14.18 and 11.08 respectively) (Sarropoulou et al, 2016).…”

“…Table 3 shows a greater development of the radicle length in G2 and, in the case of germination promoters, citrulline (CI) and tap water (TW) were the same. Sarropoulou et al (2016) carried out studies with cherry slides which had direct effects on in vitro rooting, as well as in the accumulation of proline in the leaves and roots.…”

“…Root growth and water absorption are enhanced by humic substances (HS) (Olk et al, 2018, Canellas et al, 2015du Jardin, 2015). Furthermore, Sarropoulou et al (2016) mention that metabolism and transport of citrulline has been observed in Arabidopsis thaliana and Cucurbitaceae crops. In studies performed with cherry slides, there were direct effects on in vitro rooting.…”

Objective: Plant life begins at germination. Stimulating germination with chemical methods can be advantageous. The pregerminative treatment of four promoters was determined in two maize genotypes (G1, G2). Design/methodology/approach: Sixty seeds per Petri dish were used as experimental unit with three repetitions, organized in a completely randomized 2×4 factorial design. Two factors were taken into consideration: A) Genotypes (G1, G2); and B) four pregerminative promoters. The genotypes were Antelope G1 and yellow Antelope G2. Meanwhile, the pregerminative promoters were salicylic acid (‎C7H6O3) (SA), citrulline (C6H13N3O3) (CI), humic substances derived from leonardite (HS), and tap water (TW), in 1000-ppm concentrations. The following variables were evaluated: germination percentage (GP)/days-1, radicle diameter (RD), radicle length (RL), and number of lateral seminal roots (NSR). An analysis of variance and Tukey tests (α £ 0.05) were performed. Results: The germination promoters were highly significant in both genotypes, as well as during the promoter-genotype interaction. G1 and G2 means showed a higher growth and development for humic substances (HS) during germination in the NSR. Study Limitations/Implications: Germination can be inhibited, if the promoters are overweighted. Findings/Conclusions: The best genotype and germination promoter (G2) had a 94% effectiveness and HS at 1000 ppm. CI and SA registered the lowest GP.
