“…Finally, significant SNP was also found in genes that were recently evidenced to play a central role in the control of leaf size ( KIX8 , Li et al 2018 ) and the homeostasis of reactive oxygen species and subsequent regulation of stomatal closure in guard cells (i.e. autophagy-associated genes ATG7 and VPS34 , Yamauchi et al 2019 , Zhang et al 2019 ). Testing the candidate SNP by amplicon sequencing on a larger panel of populations will also check their precise degree of reliability.…”

Detecting processes of local adaptation in forest trees and identifying environmental selective drivers are of primary importance for forest management and conservation. Transplant experiments, functional genomics and population genomics are complementary tools to efficiently characterize heritable phenotypic traits and to decipher the genetic bases of adaptive traits. Using an integrative approach combining phenotypic assessment in common garden, transcriptomics and landscape genomics, we investigated leaf adaptive traits in Coffea mauritiana, a forest tree endemic to Reunion Island. Eight populations of C. mauritiana originating from sites with contrasted environmental conditions were sampled in common garden to assess several leaf morphological traits, to analyze the leaf transcriptome and leaf cuticular wax composition. The relative alkane content of cuticular waxes was significantly correlated with major climatic gradients, paving the way for further transcriptome-based analyses. The expression pattern of cuticle biosynthetic genes was consistent with a modulation of alkane accumulation across the population studied, supporting the hypothesis that the composition of cuticular wax is involved in the local adaptation of C. mauritiana. Association tests in landscape genomics performed using RNA-seq-derived single-nucleotide polymorphisms revealed that genes associated with cell wall remodeling also likely play an adaptive role. By combining these different approaches, this study efficiently identified local adaptation processes in a non-model species. Our results provide the first evidence for local adaptation in trees endemic to Reunion Island and highlight the importance of cuticle composition for the adaptation of trees to the high evaporative demand in warm climates.

“…PI3K has been reported to play a positive role in the regulation of plasma membrane endocytosis and in the production of intracellular NADPH oxidase-derived ROS during salt stress [120]. The PI3K-regulated ROS generation plays a vital role in regulating rice seed vigor [121], as well as ABA-induced ROS generation and stomata closure [122][123][124]. Although PI3K plays a role in ROS signaling during salt stress, exactly how PI3P regulates ROS production and how PI3K enzyme activity is regulated by salt stress still requires further study.…”

High salinity threatens crop production by harming plants and interfering with their development. Plant cells respond to salt stress in various ways, all of which involve multiple components such as proteins, peptides, lipids, sugars, and phytohormones. Phospholipids, important components of bio-membranes, are small amphoteric molecular compounds. These have attracted significant attention in recent years due to the regulatory effect they have on cellular activity. Over the past few decades, genetic and biochemical analyses have partly revealed that phospholipids regulate salt stress response by participating in salt stress signal transduction. In this review, we summarize the generation and metabolism of phospholipid phosphatidic acid (PA), phosphoinositides (PIs), phosphatidylserine (PS), phosphatidylcholine (PC), phosphatidylethanolamine (PE) and phosphatidylglycerol (PG), as well as the regulatory role each phospholipid plays in the salt stress response. We also discuss the possible regulatory role based on how they act during other cellular activities.

“…Regulation of these responses is controlled through the phosphorylation status of specific phosphatidylinositol sites that occur in response to PAMP‐ and ETI‐based resistance (Zhang & Xiao, 2015 ). Specific responses associated with this phosphorylation include the induction of reactive oxygen species, hypersensitive defence, and stomatal closing during pathogen infection, all GO features specifically enriched in Dro141TX‐grafted scions (Zhang et al, 2020 ).…”

Grafting is a common horticultural practice used to confer desirable traits between rootstock and scion, including disease resistance. To investigate graft‐conferred resistance against viral diseases a novel heterografting system was developed using Nicotiana benthamiana scions grafted onto different tomato rootstocks. N. benthamiana is normally highly susceptible to tobacco mosaic virus (TMV) infection. However, specific tomato rootstock varieties were found to confer a range of resistance levels to N. benthamiana scions inoculated with TMV. Conferred resistance was associated with delays in virus accumulation and the reduction in virus spread. RNA sequencing analysis showed the enrichment of transcripts associated with disease resistance and plant stress in N. benthamiana scions grafted onto resistance‐inducing tomato rootstocks. Genome sequencing of resistance‐ and nonresistance‐conferring rootstocks was used to identify mobile tomato transcripts within N. benthamiana scions. Within resistance‐induced N. benthamiana scions, enriched mobile tomato transcripts were predominantly associated with defence, stress, and abscisic acid signalling when compared to similar scions grafted onto nonresistance‐inducing rootstock. Combining these findings suggests that graft‐induced resistance is modulated by rootstock scion transcriptional responses and rootstock‐specific mobile transcripts.
