“…We also found other ethylene signaling genes with significantly altered expression at day 9 (T = 3), including a predicted ethylene dependent gravitopismdeficient like gene (Cc02_g06740; FC = −3.13), multiple ethylene-responsive transcription factors (Cc05_g07590, FC = 2.21; Cc02_g03420, FC = 6.98; and Cc06_g12520, FC = 2.96), and two AP2 related TF genes (Cc10_g07680; FC = −3.09 and Cc08_g15690, FC = −3.13). Transcript changes for some ethylene related TFs could be due to overlaps between wound/damage-related responses and drought related responses (Heyman et al 2018). This is supported by the observation that several defense related genes also showed transcriptional changes at the higher water deficit, including putative disease resistance proteins (Cc01_g02600, FC = −5.16 and Cc02_g26510, F = 3.95) and pathogen related proteins (Cc11_g07780, FC = 4.68 and Cc10_g14270, FC = 4.3).…”

Climate change is expected to result in more frequent periods of both low rainfall and above normal temperatures for many coffee growing regions. To understand how coffee reacts to such change, we studied the physiological and gene expression responses of the clonal variety C. canephora FRT07 exposed to water deficits under two different temperature regimes. Variations in the timedependent impact of water deficits on leaf stomatal conductance and carbon assimilation were significantly different under the 27°C and 27°C/42°C conditions examined. The physiological responses 24 h after re-watering were also different for both conditions. Expression analysis of genes known to respond to water deficits indicated that drought-related signaling occurred at both temperatures. Deeper insights into the response of coffee to water deficits was obtained by RNASeq based whole transcriptome profiling of leaves from early, late, and recovery stages of the 27°C experiment. This yielded expression data for 13,642 genes and related differential expression analysis uncovered 362 and 474 genes with increased and decreased expression, respectively, under mild water deficits, and 1627 genes and 2197 genes, respectively, under more severe water deficits. The data presented, from a single clonal coffee variety, serves as an important reference point for future comparative physiological/ transcriptomic studies with clonal coffee varieties with different sensitivities to water deficits and high temperatures. Such comparative analyses will help predict how different coffee varieties respond to changing climatic conditions, and may facilitate the identification of alleles associated with high and low tolerance to water deficits, enabling faster breeding of more climatesmart coffee trees.

“…In addition to ET biosynthesis genes, many APETALA2/ETHYLENE RESPONSE FACTOR ( AP2/ERF ) genes were differentially expressed at various stages during the process. Several AP2/ERF genes have been recently identified as potent players in regulation of tissue repair, de novo organogenesis and regeneration (Heyman et al ), indicating possible roles of the ET‐induced AP2/ERF genes in AR formation.…”

Plants have evolved sophisticated root systems that help them to cope with harsh environmental conditions. They are typically composed of a primary root and lateral roots (LRs), but may also include adventitious roots (ARs). Unlike LRs, ARs may be initiated not only from pericycle cells, but from various cell types and tissues depending on the species. Phytohormones, together with many other internal and external stimuli, coordinate and guide every step of AR formation from the first event of cell reprogramming until emergence and outgrowth. In this review, we summarize recent advances in the molecular mechanisms controlling AR formation and highlight the main hormonal cross talk involved in its regulation under different conditions and in different model systems.

“…Our results suggested that the wild alleles of ScWRKY023 and ScWRKY045 might represent promising candidates for multiple stress responses as they are leaf-specific and constantly expressed after wounding in S. commersonii but not in the cultivated potato. In addition, WRKY023 is also induced by bacterial infection and it is suggested to interact with both a WRAF2-like protein and with the LRR mediated immunity system 74,75 .…”

Wild potatoes, as dynamic resource adapted to various environmental conditions, represent a powerful and informative reservoir of genes useful for breeding efforts. WRKY transcription factors (TFs) are encoded by one of the largest families in plants and are involved in several biological processes such as growth and development, signal transduction, and plant defence against stress. In this study, 79 and 84 genes encoding putative WRKY TFs have been identified in two wild potato relatives, Solanum commersonii and S. chacoense. Phylogenetic analysis of WRKY proteins divided ScWRKYs and SchWRKYs into three Groups and seven subGroups. Structural and phylogenetic comparative analyses suggested an interspecific variability of WRKYs. Analysis of gene expression profiles in different tissues and under various stresses allowed to select ScWRKY045 as a good candidate in woundingresponse, ScWRKY055 as a bacterial infection triggered WRKY and ScWRKY023 as a multiple stressresponsive WRKY gene. Those WRKYs were further studied through interactome analysis allowing the identification of potential co-expression relationships between ScWRKYs/SchWRKYs and genes of various pathways. Overall, this study enabled the discrimination of WRKY genes that could be considered as potential candidates in both breeding programs and functional studies.Plants experience environmental constrains and pathogen attacks during their life. Being sessile organisms, their survival depends on the ability to properly and promptly reprogram cellular networks. Several and different classes of transcription factors (TFs) work as "master regulators" and "selector genes", being able to control processes that specify cell types and developmental patterning and modulate specific pathways. Among them, WRKY factors are drawing a great deal of interest in the scientific community due to their ability to simultaneously cope with multiple stresses 1,2 . They are notorious for coordinating signals in plant immunity response against several pathogens and pest attacks 3,4 . More recently, it has been confirmed that WRKYs also base defence mechanism to abiotic stresses and play a key role in cross-talk pathway networks between plant response and development 5,6 . Their involvement into multiple stress response and in plant growth regulation is evidenced by their W-box specific DNA binding 7,8 . Besides, WRKY binds sugar responsive elements and, very recently, it has been demonstrated that they activate sugar responsive genes through an epigenetic mechanism of control 9 . The systematic classification of components of the WRKY family is well organized. It is based on the WRKY binding domain (WD) characteristics along with those of the Zinc Finger (ZF) motif, which is typically present downstream the WD. WD consists of 60 amino acids structured as four-stranded β-sheets able to enter the major groove of B-form DNA. The highly conserved motif is "WRKYGQK". According to the number of WDs and the type of zinc finger motif, WRKY proteins can be classified into three Groups,...
