“…This phenomenon in nectarine may be due to the loss of trichomes during evolution, enhancing its susceptibility to stresses. Evidence of conspicuous changes in the metabolic and catalytic processes associated with this phenomenon in plants under abiotic stress are reported (Cardoso et al; Khan et al, 2019).…”

Peach (Prunus persica) is an economically significant fruit-bearing tree. The trichomes of peach fruits are essential for their growth and development by playing a protective role against abiotic stresses, such as intense ultraviolet (UV) light, high temperature, cold-induced stress, and biotic stresses, such as pests and disease infestation. However, the mechanism underlying trichome development in peach fruits is unknown. Therefore, spatial transcriptome sequencing technology was used to compare the transcriptomic information seven days after flowering (DAF) of peach and nectarine fruits at an ultra-high resolution. The results revealed significant variations in how fruits at the early development stage responded to stress exposure. Comparatively, nectarine response to stress was significantly magnified than peach. Notably, a novel trichome-related marker gene,Prupe.7G196500, was identified in peach, which showed a robust function in response to jasmonic acid and wounding. Further, thePrupe.7G196500pro::GUSconstruct was found to specifically expressed in the trichomes of the true leaves of 10-day-oldArabidopsis thaliana(Arabidopsis) seedlings and induced by drought treatment. Finally, gain-of-function analysis showed thatPrupe.7G196500promoted trichomes development. In conclusion, this study identified the cell types and novel marker genes associated with peach fruit. The role ofPrupe.7G196500in positively regulating trichome development was also characterized, thereby laying the foundation for analyzing the mechanism involved in trichome development in peach fruits.

“…Purple, blue and turquoise modules had opposite results, with positive correlations between gene expression and amino acid and SA concentrations and negative correlations between the agronomic traits and several physiological traits such as photosynthetic rate, stomatal conductance and the ratio of intercellular to ambient CO 2 concentrations (Figure 5). This demonstrates the tradeoff between plant productivity and stress resilience in commercial wheat cultivars as amino acid metabolism has been shown to be a key node in plant stress acclimation across multiple crop species (Cardoso et al, 2022). DETs from these modules and their annotations have been included in Table S5.…”

SUMMARYField‐grown crops rarely experience growth conditions in which yield can be maximized. Environmental stresses occur in combination, with advancements in crop tolerance further complicated by its polygenic nature. Strategic targeting of causal genes is required to meet future crop production needs. Here, we employed a systems biology approach in wheat (Triticum aestivum L.) to investigate physio‐metabolic adjustments and transcriptome reprogramming involved in acclimations to heat, drought, salinity and all combinations therein. A significant shift in magnitude and complexity of plant response was evident across stress scenarios based on the agronomic losses, increased proline concentrations and 8.7‐fold increase in unique differentially expressed transcripts (DETs) observed under the triple stress condition. Transcriptome data from all stress treatments were assembled into an online, open access eFP browser for visualizing gene expression during abiotic stress. Weighted gene co‐expression network analysis revealed 152 hub genes of which 32% contained the ethylene‐responsive element binding factor‐associated amphiphilic repression (EAR) transcriptional repression motif. Cross‐referencing against the 31 DETs common to all stress treatments isolated TaWRKY33 as a leading candidate for greater plant tolerance to combinatorial stresses. Integration of our findings with available literature on gene functional characterization allowed us to further suggest flexible gene combinations for future adaptive gene stacking in wheat. Our approach demonstrates the strength of robust multi‐omics‐based data resources for gene discovery in complex environmental conditions. Accessibility of such datasets will promote cross‐validation of candidate genes across studies and aid in accelerating causal gene validation for crop resiliency.
