“…Axonopus compressus , also known as carpet grass is a robust, stoloniferous grass with flowering stems that can be up to 45 cm tall. It is widely naturalized and used as a turf and forage in the humid tropics and subtropics ( Wang et al 2014 ; Nawaz et al 2021 ). The leaves generally form a dense mat that seldom reaches a height of >15 cm ( Wang et al 2014 ).…”

Axonopus compressus also known as carpet grass is a robust, stoloniferous grass that can grow in minimal fertilization and resists well to abiotic and biotic stresses including low nitrogen (LN) stress. This study aimed at characterizing the agro-morphological and metabolome responses to LN in carpet grass leaves. Under LN stress, carpet grass increased yellowness of leaves and root dry matter while reduced turf quality and shoot dry weight. The metabolome comparison between samples from optimum and LN conditions indicated 304 differentially accumulated metabolites (DAMs), which could be classified into 12 major and 31 sub-classes. The results revealed that the leaf tissues accumulated more anthocyanins and other flavonoid metabolites under LN stress. Conversely, amino acids, nucleic acids and their derivatives were reduced in response to LN stress. The overall evaluation of individual metabolites and pathways, and previous studies on metabolomes indicated that carpet grass reduced its energy consumption in leaves and increased the level of organic acid metabolism and secondary metabolism in order to resist LN stress conditions.

“…Axonopus is a genus of the grass family (Paniceae; Poaceae; Triticeae). Approximately 100 species of Axonopus have already been determined [1], and they are generally distributed along shoreline of the China and Africa, Alaska, central Asia, eastern Asia, North Sea, South America and Oceania [2,3]. There are about more than 40% (55.5×106 km2) of Earth's surface occupied by Grasslands world-wide, Greenland and Antarctica are not included [4].…”

Highlights:1. Axonopus compressus can stand severe drought stress by activating the potential defense mechanism.2. We investigated the differential transcriptome of drought stressed and normal Axonopus compressus plants3. New comers have been identified that involved in the drought response4. Identified drought responsive genes which never known for other stresses.5. The identified genes also respond to stress in Arabidopsis thaliana in different manners.Background: Carpet grass [Axonopus compressus (L.)] is an important warm season perennial grass around the world and is renowned for its adaptability to varied environmental conditions. However, Carpet grass lacks enough data in public data bank, which confined our comprehension of the mechanism of environmental adaptations, gene discovery and development of molecular marker. Methods: In current study, the DEGs (differentially expressed genes) in Axonopus compressus under drought stress (DS) were identified and compared with CK (control) by RNA-Seq. Results: the 263,835 of total unigenes were identified in Axonopus compressus, and 201,303 (also add the numbers of remaining2 data bases) a sequence of unigenes significantly matched in at least one of the seven databases. A total of 153697 (58.25%) unigenes can be classified to 144 KEGG pathways, and 7,444 unigenes were expressed differentially between DS and CK, of which 4,249 were up-regulated and 3,195 were down-regulated unigenes. Of the 50 significantly enriched GO terms, 18, 6 and 14 items were related to BP, CC and MF, respectively. Analysis of KEGG enrichment showed 2569 DEGs involved in 143 different pathways, under drought stress 2,747 DEGs were up-regulated and 2,502 DEGs were down-regulated. Moreover, we identified 352 transcriptor factors (TFs) in Axonopus compressus, of which 270 were differentially expressed between CK and DS. The qRT-PCR validation experiment also support the transcriptional response of Axonopus compressus against drought. Conclusions: The current findings provide the first framework for further investigation for the particular roles of these unigenes in Axonopus compressus in response to droughts.

The qRT-PCR validation experiment also support the transcriptional response of Axonopus compressus against drought. Accuracy of transcriptome unigenes of Axonopus compressus was assessed with BLAST, which showed 3,300 sequences of Axonopus compressus in the NCBI.Conclusion: The 7,444 unigenes were found to be between DS and CK treatments which indicate that there is a strong mechanism of drought tolerance in Axonopus compressus. The current findings provide the first framework for further investigations for the particular roles of these unigenes in Axonopus compressus in response to drought.
