“…Furthermore, three archaeal taxa were negatively influenced by the plant Thermopsis lanceolata that did not share the same response type to nutrient addition; and Elymus nutans positively and negatively influenced 4 and 1 bacterial taxa, respectively, covering a broad range of response types. Interestingly, T. lanceolata is characterized by specific compounds like anagyrine, cytisine and thermopsine (Gao, Li, Jiang, & Zhu, ; Vinogradova, Iskandarov, & Yunusov, ) which have negative impacts on some bacteria (Pérezlaínez et al, ; Nemesio et al, ); A. rivularis roots are characterized by antioxidant compounds with antibacterial activity (Hao, Gu, & Xiao, ; Shi, Wei, Wei, & Wu, ) and E. nutans has been reported to exudate specific compounds that inhibit seed germination of several plants (Zeng, Mallik, & Luo, ). It is thus likely that the influence of these three plant species on particular microbial taxa is due to the effect of the very specific compounds they produce.…”

Nitrogen (N) and phosphorus (P) often limit biological processes in terrestrial ecosystems. Based on previous studies mainly focusing on plants, the concept of resource limitation has evolved towards a theory of (co)limitations by multiple resources. However, this ecological framework has not been applied to analyse how soil micro‐organisms and plants concurrently respond to N and/or P addition, and whether these responses are constrained by phylogenetic relatedness. Here, we applied this framework to analyse microbial and plant responses at community and taxon levels to different fertilization treatments (four N levels without P; four P levels without N and four NP levels) in Tibetan grasslands. Total plant biomass showed serial limitation by N then P, and most plant species were limited by N only. Total archaeal abundance decreased with P addition, but diverse nutrient limitation types were observed for archaeal taxa. Closely related archaeal taxa tended to similarly respond to N, and functional similarity between distant archaeal groups was observed for response to P, possibly due to functional convergence. In contrast, total bacteria slightly increased with P addition only when plants remained N limited, whereas without N limitation, plants rather than bacteria benefited from P addition. Most bacterial taxa were limited by other resources than N and P, and no clear phylogenetic signals were observed regarding bacterial responses to N/P additions. Synthesis. We propose a novel approach for characterizing microbial response types to nutrient addition. It demonstrates that in Tibetan meadows, most dominant plant species, archaea and bacteria, respectively, depend on N, both N and P and other resources.

Thermopsis lanceolata R. Br. belongs to the genus Thermopsis , Fabaceae. The alkaloids of T. lanceolata have anti-cancer, anti-heart rate disorders and other pharmacological effects. To explore the chloroplast genome of T. lanceolata and its phylogenetic relationship, a complete chloroplast genome of T. lanceolata was sequenced and annotated, and a phylogenetic tree was constructed. The complete chloroplast genome of T. lanceolata is a circular molecule of 151,526 bp, consisting of a large single copy (LSC) region of 83,780 bp, a small single copy (SSC) region of 15,566 bp, and a pair of inverted repeats (IRa and IRb) of 26,090 bp. The chloroplast genome of T. lanceolata contained 130 genes, including 85 protein-coding genes, 37 transfer RNA genes, and 8 ribosomal RNA genes. Phylogenetic analysis revealed a close relationship between T. lanceolata and T. turkestanica .

“…Thermopsis lanceolata was reported to contain pachycarpine ((+)-sparteine) and is proposed as a potential source of this alkaloid. 10 Khristov et al 11 reported a method to obtain (−)-sparteine sulfate from Chamaecytisus absinthioides in 0.7% yield by steam distillation and subsequent treatment with sulfuric acid. Cionga et al 12 considered that steam distillation of the alkalinized plant Sarothamnus scoparius is more advantageous, arguing that up to 90% of the alkaloid content can be extracted.…”

(−)-Sparteine sulfate is a stable salt of the quinolizidine chiral diamine alkaloid (−)-sparteine. This compound, in addition to presenting various biological activities, has successfully been used as a ligand and organocatalyst in enantioselective lithiation reactions in asymmetric synthesis. (−)-Sparteine free base deteriorates gradually, even in refrigeration, but its stable salt, (−)-sparteine sulfate, offers advantages in handling and storage. To the best of our knowledge, no process exists in the literature for obtaining (−)-sparteine sulfate from the species of the plant genus Lupinus. In this work, we present an efficient and sustainable process to obtain (−)-sparteine sulfate and free base (−)-sparteine from leaves and stems of Lupinus montanus.
