“…For example, 1-MCP treatment in pak-choy (lower shelf-life like kale and broccoli) delayed the senescence and yellow of leaves by maintaining the chloroplast integrity during the storage at 20 °C [ 28 ]. Additionally, high throughput studies have identified hundreds of potential SAGs, some of which have been further demonstrated to have roles in senescence using functional genomics and reverse genetics approaches [ 15 ].…”

“…ore15 mutants exhibited increased leaf longevity and delayed leaf yellowing as compared to wild type. ore15 mutants showed delayed leaf senescence in response to dark, salt or oxidative stresses [ 15 ]. Expression studies have revealed that ORE15 transcript levels were mostly concentrated in young leaves and at lower levels in ageing leaves [ 15 ].…”

The genus Brassica comprises a highly diverse range of vegetable crops varying in morphology, harvestable crop product, and postharvest shelf-life that has arisen through domestication, artificial selection and plant breeding. Previous postharvest studies on the shelf-life of Brassica species has mainly focused on the variable rates of physiological changes including respiration and transpiration. Therefore, further understanding of the molecular basis of postharvest senescence in Brassica vegetables is needed to understand its progression in improving their postharvest shelf-life. The aim of this study was to better understand the trajectory of molecular responses in senescence-associated genes but not induced by ethylene and ethylene-induced genes towards altered postharvest storage conditions. After storage at different temperatures, the expression levels of the key senescence-associated genes (SAGs) and the ethylene biosynthesis, perception, and signaling genes were quantitatively analyzed in cabbage, broccoli and kale. The expression levels of these genes were tightly linked to storage temperature and phase of senescence. Expression of ORE15, SAG12, and NAC29 were continuously increased during the twelve days of postharvest storage at room temperature. Prolonged exposure of these three vegetables to cold temperature reduced the variation in the expression levels of ORE15 and SAG12, observed as mostly decreased which resulted in limiting senescence. The transcript levels of the ethylene receptor were also decreased at lower temperature, further suggesting that decreased ethylene biosynthesis and signaling in cabbage during postharvest storage would delay the senescence mechanism. These results enhanced our understanding of the transcriptional changes in ethylene-independent SAGs and ethylene-related genes in postharvest senescence, as well as the timing and temperature sensitive molecular events associated with senescence in cabbage, broccoli and kale and this knowledge can potentially be used for the improvement of postharvest storage in Brassica vegetables.

“…( Liu et al, 2020 ). AtPLATZ3 (ORESARA15) enhances leaf growth by promoting the rate and duration of cell proliferation in the early growth stages and suppresses leaf senescence in later stages ( Kim et al, 2018 ; Jun et al, 2020 ). AtPLATZ7 ( RITF1 , RGF1-INDUCIBLE TRANSCRIPTION FACTOR1) plays a central role in mediating RGF1 signaling, which controls root meristem size through ROS signaling ( Yamada et al, 2020 ).…”

Plant AT-rich protein and zinc-binding protein (PLATZ) is a class of plant-specific zinc-dependent DNA-binding protein that binds to A/T-rich DNA sequences. PLATZ plays an important role in seed development, water tolerance, and cell proliferation in early plant growth. In this study, 11 GbPLATZs were identified from the ginkgo genome with complete PLATZ-conserved domains, which represents a smaller number compared with angiosperms. Multi-species phylogenetic analysis showed that PLATZ genes were conserved in seed plants, and the 11 members were represented by four groups, among which groups I and II were closely related. Analysis of gene structures, sequence module characteristics, and expression patterns showed that GbPLATZs were similar within and differed between groups. RNA-seq and qRT-PCR results showed that GbPLATZs had distinct expression patterns. Most genes were associated with seed development, among which six genes were highly related. Subcellular localization experiments showed that six GbPLATZ proteins related to seed development were localized in the nucleus, suggesting that they might function as traditional transcription factors. This study provides a basis for understanding the structural differentiation, evolutionary characteristics, expression profile, and potential functions of PLATZ transcription factors in Ginkgo biloba.
