“…The PAOs from H. vulgare ( HvPAO1 , HvPAO3 , HvPAO4 , HvPAO6 , HvPAO7 , and HvPAO8 ) are expressed systemically in all the vegetative tissues except HvPAO2 , which is expressed in sterile spikelets and embryos [ 23 , 24 ]. Similarly, the PAOs from T. aestivum ( TaPAO3 , TaPAO5 , TaPAO8 , and TaPAO11 ) are expressed systemically in vegetative tissues; however, TaPAO5 , TaPAO8 , and TaPAO11 , which are also found to be expressed in the reproductive parts [ 56 ]. The PAOs from Z. mays ( ZmPAO2 , ZmPAO3 , ZmPAO5 , ZmPAO8 , and ZmPAO9 ) are systemically expressed in all the vegetative tissues, while ZmPAO4 and ZmPAO6 are expressed specifically in roots and stems only.…”

Polyamines (PAs) are positively charged amines that are present in all organisms. In addition to their functions specific to growth and development, they are involved in responding to various biotic and abiotic stress tolerance functions. The appropriate concentration of PA in the cell is maintained by a delicate balance between the catabolism and anabolism of PAs, which is primarily driven by two enzymes, namely diamine oxidase and polyamine oxidase (PAO). PAOs have been found to be localized in multiple subcellular locations, including peroxisomes. This paper presents a holistic account of peroxisomal PAOs. PAOs are flavin adenine dinucleotide-dependent enzymes with varying degrees of substrate specificity. They are expressed differentially upon various abiotic stress conditions, namely heat, cold, salinity, and dehydration. It has also been observed that in a particular species, the various PAO isoforms are expressed differentially with a spatial and temporal distinction. PAOs are targeted to peroxisome via a peroxisomal targeting signal (PTS) type 1. We conducted an extensive bioinformatics analysis of PTS1s present in various peroxisomal PAOs and present a consensus peroxisome targeting signal present in PAOs. Furthermore, we also propose an evolutionary perspective of peroxisomal PAOs. PAOs localized in plant peroxisomes are of potential importance in abiotic stress tolerance since peroxisomes are one of the nodal centers of reactive oxygen species (ROS) homeostasis and an increase in ROS is a major indicator of the plant being in stress conditions; hence, in the future, PAO enzymes could be used as a key candidate for generating abiotic stress tolerant crops.

“…Primary-amine oxidase (AOC3, AOC2, tynA, EC 1.4.3.21) is a heterogeneous enzyme, including copper amine oxidases (CuAOs) and flavin-containing polyamine oxidase (PAO), which catalyzes the deamination of polyamines (PAs) to amino aldehydes. It was found that copper amine oxidase (AtCuAO) in plants regulated H 2 O 2 related to abscisic acid (ABA)-induced stomatal closure [ 81 ], and participated in wound healing, defense against pathogens [ 82 ], and indole-3-acetic acid (IAA)/jasmonic acid/ABA signal transduction pathways [ 81 ], such as the closure of stomata induced by ABA [ 83 , 84 ]. In our results, we speculated that chilling-induced mobile Cmo mRNA of CuAO participated in the conversion of aminoacetone to pyruvaldehyde.…”

Cucumber (Cucumis sativus L.) often experiences chilling stress that limits their growth and productivity. Grafting is widely used to improve abiotic stress resistance by alternating a vigorous root system, suggesting there exists systemic signals communication between distant organs. mRNAs are reported to be evolving in fortification strategies by long-distance signaling when plants suffering from chilling stress. However, the potential function of mobile mRNAs alleviating chilling stress in grafted cucumber is still unknown. Here, the physiological changes, mobile mRNAs profiling, transcriptomic and metabolomic changes in above- and underground tissues of all graft combinations of cucumber and pumpkin responding to chilling stress were established and analyzed comprehensively. The co-relationship between the cluster of chilling-induced pumpkin mobile mRNAs with Differentially Expressed Genes (DEGs) and Differentially Intensive Metabolites (DIMs) revealed that four key chilling-induced pumpkin mobile mRNAs were highly related to glycine, serine and threonine synthesis and fatty acid β-oxidative degradation metabolism in cucumber tissues of heterografts. The verification of mobile mRNAs, potential transport of metabolites and exogenous application of key metabolites of glycerophospholipid metabolism pathway in cucumber seedlings confirmed that the role of mobile mRNAs in regulating chilling responses in grafted cucumber. Our results build a link between the long-distance mRNAs of chilling-tolerant pumpkin and the fatty acid β-oxidative degradation metabolism of chilling-sensitive cucumber. It helps to uncover the mechanism of signaling interaction between scion and stock responding to chilling tolerant in grafted cucumber.

Background As maize originated in tropical or subtropical zones, most maize germplasm is extremely sensitive to low temperatures during the seedling stage. Clarifying the molecular mechanism of cold acclimation would facilitate the breeding of cold tolerant maize varieties, which is one of the major sustainability factors for crop production. To meet this goal, we investigated two maize inbred lines with contrasting levels of cold tolerance at the seedling stage (IL85, a cold tolerant line; B73, a cold sensitive line), and performed full-length transcriptome sequencing on the root tips of seedlings before and after 24 h of cold treatment. Results We identified 152,263 transcripts, including 20,993 novel transcripts, and determined per-transcript expression levels. A total of 1,475 transcripts were specifically up-regulated in the cold tolerant line IL85 under cold stress. GO enrichment analysis revealed that 25 transcripts were involved in reactive oxygen species (ROS) metabolic processes and 15 transcripts were related to the response to heat. Eight genes showed specific differential alternative splicing (DAS) in IL85 under cold stress, and were mainly involved in amine metabolism. A total of 1,111 lncRNAs were further identified, 62 of which were up-regulated in IL85 or B73 under cold stress, and their corresponding target genes were enriched in protein phosphorylation. Conclusions These results provide new insights into the molecular mechanism of cold acclimation during the seedling stage in maize, and will facilitate the development of cultivars with improved cold stress tolerance.
