“…They are involved in electron transport between PSII and PSI, and used for ATP formation [24]. The earliest result is also in agreement with the current study, which showed petE, petF, petH, and F-type ATPase subunit gamma, delta, and b were downregulated under dark conditions [23]. Therefore, we speculate that alteration in the expression of genes involved in PSI and PSII may be responsible for the etiolated stem.…”

“…Similarly, psaB (c53042.graph_c0), psaN (c43347.graph_c0), psaO (c41978.graph_c0), psaD-G, and psaL in PSI were also downregulated. Wang et al (2020) also reported the downregulation of PSI genes (psbB, psbO, psbR, psbP, psbQ, and psbS) and PSII genes (psaB, psaD-G, psaL, psaN, and psaO) in the etiolated cotyledons of Cunninghamia lanceolate [23]. Furthermore, the genes for components of cytochrome b6f complex, such as petC (c37658.graph_c0 and c38988.graph_c0); photosynthetic electron transport, such as petE (c30570.graph_c0), petF (4 genes), and petH (c48071.graph_c0); and F-type H + -transporting ATPase subunits gamma (c39370.graph_c0), delta (c43471.graph_c0), and b (c37746.graph_c0) were also found to be downregulated in mid and post-blanching samples.…”

In the agricultural field, blanching is a technique used to obtain tender, sweet, and delicious water dropwort stems by blocking sunlight. The physiological and nutritional parameters of blanched water dropwort have been previously investigated. However, the molecular mechanism of blanching remains unclear. In the present study, we investigated transcriptomic variations for different blanching periods in the stem of water dropwort (pre, mid, post-blanching, and control). The results showed that many genes in pathways, such as photosynthesis, carbon fixation, and phytohormone signal transduction as well as transcription factors (TFs) were significantly dysregulated. Blanched stems of water dropwort showed the higher number of downregulated genes in pathways, such as photosynthesis, antenna protein, carbon fixation in photosynthetic organisms, and porphyrin and chlorophyll metabolism, which ultimately affect the photosynthesis in water dropwort. The genes of hormone signal transduction pathways (ethylene, jasmonic acid, brassinosteroid, and indole-3-acetic acid) showed upregulation in the post-blanched water dropwort plants. Overall, a higher number of genes coding for TFs, such as ERF, BHLH, MYB, zinc-finger, bZIP, and WRKY were overexpressed in blanched samples in comparison with the control. These genes and pathways participate in inducing the length, developmental processes, pale color, and stress tolerance of the blanched stem. Overall, the genes responsive to blanching, which were identified in this study, provide an effective foundation for further studies on the molecular mechanisms of blanching and photosynthesis regulations in water dropwort and other species.

Adventitious root formation is the key to successful propagation of olives through cuttings. Etiolation, as an eco-friendly practice, can modulate the plant’s endogenous phytohormone, which plays an important role in stimulation of rooting of cuttings. Therefore, this study was aimed to investigate the effect of etiolation on the rooting behavior of both ‘Manzanillo’ and ‘Picual’ olive cuttings (terminal and sub-terminal) treated with IBA (0, 4000 ppm). The results indicated that sub-terminal cuttings in both cultivars were more effective in olive propagation than terminal cuttings as they recorded increased leaves number, C/N ratio, total carbohydrates, total indoles, IAA, IAA/GA ratio, and total phenols. Etiolation of both olive cultivars for both terminal and sub-terminal cuttings significantly decreased rooting percent, roots number, IAA, and IAA/GA ratio; while, it increased GA and GA/IAA. Moreover, etiolation decreased total sugars, IAA, IAA/GA ratio, and indole/phenol ratio in both sub-terminal cuttings. Terminal ‘Manzanillo’ cuttings achieved a higher rooting percent than terminal ‘Picual’ cuttings by 5.83% and 202.2% as mean of both seasons for untreated and IBA-treated cuttings, which was accompanied by significant increase in vascular bundle%, total phenol, phenol/indole ratio, IAA, and IAA/GA ratio by 21.48%, 49.2%, 44.72%, 12.9%, and 22.9%, respectively. Also, terminal ‘Manzanillo’ cuttings recorded lower GA by 7.98% and GA/IAA ratio by 18.21% and pith by 6.13% than terminal ‘Picual’ cuttings. This study proved that olive plants need exposure to full sunlight to propagate easily by cuttings since etiolation had negative effects on IBA-treated cuttings.
