“…ELIPs were reported to be regulated by CRY1 and HY5 in Arabidopsis (Apoorva et al, 2021; Hayami et al, 2015; Kleine et al, 2007). To investigate the relationship between RhHY5 and RhELIP3 , we cloned the RhELIP3 promoter and discovered five G‐box elements within it.…”

Light stress is one of the important stresses for winter survival in evergreens, especially for plants with broad leaves, like evergreen rhododendrons. Photoprotection has been shown to upregulate dramatically in rhododendrons during winter, but whether it directly contributes to enhancing the freezing tolerance is still unknown.In this study, we found that the expression and circadian rhythm of an early light-induced protein (ELIP)-RhELIP3-which exerts photoprotection in Rhododendron 'Elsie Lee', could be impacted by both photoperiod and low temperature, with low temperature being the predominant inducer. Arabidopsis overexpressing RhELIP3 displayed significantly stronger freezing tolerance and better photosystem II function after a 3-day recovery from freezing treatment. Moreover, RhHY5 binds with the RhELIP3 promoter to activate its expression. Arabidopsis overexpressing RhHY5 exhibited stronger freezing tolerance and better photosystem II function.AtELIP1 and AtELIP2 were significantly induced in RhHY5-overexpressed Arabidopsis at low temperatures. We also discovered that RhBBX24 binds directly to RhELIP3 promoter and suppresses its expression. RhBBX24 can also interact with RhHY5 and inhibit the interaction of RhHY5-RhELIP3. RhELIP3, RhHY5, and RhBBX24 exhibited similar circadian rhythms under low temperature with short period. Overall, our investigation highlights that photoprotection is involved in improving the freezing tolerance of evergreen rhododendrons.

An experiment was carried out using virus-resistant papaya variety Pune Selection-3 to study the effect of different cultivation methods for enhanced production and input use efficiency at Horticultural Research Farm, RAU, Pusa during the year 2016-2019. The outcomes of raised bed cultivation (a), drip irrigation (b), fertigation (c), polyethylene mulching (d) along with micronutrient spray (e) were analyzed using different combinations of these parameters as treatments for growth, yield-related parameters, and fruit quality. Nutrient use efficiency was also assessed by examining various interactive components such as soil nutrient content, nutrient acquisition with nutrient content in the leaves, the efficiency of nutrient utilization informs of the biomass produced, fruit yield, and fruit nutritional quality. The plant height was maximum in T1 (155 cm) which was significantly higher than the plant of control treatment. The flowering time was found to be reduced in all treatments. However, total soluble sugar was higher in T3. Overall, when the B:C ratio was compared, the treatment (T1) showed a higher value along with a 2.38-fold fruit yield/plant and 0.89-fold increase in fruit yield per hectare. The nutritional quality of fruits enhanced in T1 treated plants having a 1.78-fold increment in flavonoid content, and 1.2-fold more lycopene. The phenolic content was also 1.8-fold higher than the control (T5). The result obtained in the present study demonstrates that with the implementation of a suitable fertigation system in papaya cultivation we can obtain papaya growth, fruit yield per plant, and fruit quality by targeting enhancement in cost: benefit ratio.

“…UV‐B radiation is an abiotic stress that can significantly affect the secondary metabolisms and antioxidant systems in plants. Because of this effect, it has been widely applied to induce the desirable accumulation of bioactive compounds in many medicinal plants (Apoorva et al, 2021; Nocchi et al, 2020). The effects of UV‐B radiation on the flavonoid accumulation of S. baicalensis plants have been studied in previous works (Liu et al, 2014; Zhang et al, 2014; Zhou et al, 2020).…”

Ultraviolet‐B (UV‐B) radiation is one of the abiotic stresses that can significantly affect the secondary metabolite accumulation in in vitro tissue cultures of medicinal plants. The present study investigated the effects of UV‐B radiation on the secondary metabolites and antioxidant activities of Scutellaria baicalensis in vitro shoots grown at different concentrations of 6‐benzyl aminopurine (6‐BA), which is the cytokinin most widely used in plant tissue culture. The UV‐B radiation caused significant increases in lipid peroxidation, total phenolic, and flavonoid contents, and antioxidant activities in the in vitro shoots grown at lower 6‐BA concentrations (0 and 1 mg L−1), while it did not cause any significant changes in those grown at higher 6‐BA concentrations (2 and 3 mg L−1). However, the UV‐B radiation significantly altered the contents of main individual flavonoids at both lower and higher 6‐BA concentrations. Upon UV‐B radiation, aglycones (including baicalein, wogonin, and scutellarein) increased, while glucuronides such as baicalin and wogonoside decreased; this was more evident at higher 6‐BA concentrations. This study demonstrated that the effects of UV‐B radiation on the secondary metabolites of S. baicalensis in vitro shoots highly depended on the 6‐BA concentration in the culture medium.
