“…Ineffective ROS removal would eventually lead to the peroxidation of lipids in biological membranes. That includes thylakoid membranes and cause disturbance of the photosynthetic electron transport as well as the decrease of overall photosynthetic efficiency (Allen & Ort, 2001; Einset et al, 2007; Hajihashemi, Brestic, Landi, & Skalicky, 2020; Jung, 2004; Lepeduš et al, 2011; Mlinarić, Antunović Dunić, Štolfa, Cesar, & Lepeduš, 2016; Tian et al, 2016; Ünyayar & Çekiç, 2005). Even at low light intensities, cold stress may cause photoinhibition and cause damage at both photosystems, photosystem II (PSI I) and PSI by disturbing energy distribution between photosystems (Li & Zhang, 2016; Xiao, Zhang, Yang, & Zhang, 2019).…”

“…Unlike the most other woody species, young fig leaves initiate at the top of the canopy during the whole summer. Those young, still developing leaves, are the ones that are the most exposed to changes in the environment, especially to the changes of light intensity and temperature fluctuations (Hou et al, 2016; Jiang et al, 2006; Krause et al, 1995; Mlinarić et al, 2016; Mlinarić, Antunović Dunić, Skendrović Babojelić, Cesar, & Lepeduš, 2017; Saropulos & Drennan, 2002). Young developing leaves are usually more prone to photoinhibition and damage due to the changes of the microclimatic conditions than fully grown, mature ones (Cechin, Rossi, Oliveira, & Fumis, 2006; Jiang et al, 2006; Krause et al, 1995).…”

“…Our previous research on common fig variety Zamorčica revealed that developing leaves have fully functional photosynthetic apparatus and efficient photoprotective strategies to cope with increased temperature and irradiation during summer days (Mlinarić et al, 2016, 2017). Common fig varieties differ in leaf and fruit morphology, but also in their tolerance to different environmental conditions.…”

Common fig (Ficus carica L.) is widely cultivated Mediterranean species. Such warm‐climate species are adapted to elevated temperatures and are susceptible to chilling stress (0–12°C). However, occasional short chilling periods are common during growing season in temperate areas that can affect functionality of the plant. The aim of this work was to investigate influence of short‐term chilling stress on antioxidative response and PSII photochemistry in developing leaves of two common fig varieties: Zamorčica and Green matalon. Leaves were detached from the trees, acclimated at room temperature in dark for 16 hr and then exposed to low temperature (10°C) at low irradiation (50 μmol m−2 s−1) for 4 hr. Dark adapted leaves were considered as the control. The damage to the membranes was determined as lipid peroxidation (thiobarbituric acid reactive substances) while the antioxidative response was evaluated by determining activities of the selected antioxidative enzymes. Photosynthetic performance was analysed by measuring in vivo chlorophyll a fluorescence (ChlF) increase. Relative accumulation of the main photosynthetic proteins (D1 and Rubisco LSU) was determined, as well. Due to efficient antioxidative activity, neither of investigated variety showed damage of the membrane lipids. Both varieties revealed functional antennae and its good connectivity to their reaction centres shown as negative L and K bands as well as stable D1 protein accumulation suggesting functional electron transport through photosystem II (PSII) and efficient primary photochemistry. Blocked electron flow further than QA resulted in limitation of the Photosystem I (PSI) functionality in both varieties. Due to differential relative accumulation of D1 and Rubisco LSU proteins upon the chilling stress, Zamorčica revealed greater decrease of the main photosynthetic parameters derived from in vivo ChlF induction (PItotal, PIABS and φP0) in comparison to Green matalon. In addition, increased specific energy fluxes through PSII in Zamorčica suggested its higher susceptibility to photoinhibition caused by chilling stress in comparison to Green matalon.

“…The same mixture, with no extract added and without illumination, was used as a blank. One unit of SOD activity was defined as the amount of enzyme required to cause 50% inhibition of the rate of NBT reduction, compared to the same illuminated sample with no added enzyme (Mlinarić, Antunović‐Dunić, Štolfa, Cesar, & Lepeduš, ).…”

Phytochemical variation mediates the susceptibility of insect herbivores to entomoviruses

It has been reported that the susceptibility of insect herbivores to entomoviruses is affected by phytochemicals ingested during the acquisition of viral inoculum on the foliage of host plants. However, the relationship between this susceptibility and phytochemicals is poorly understood. To test this hypothesis of plant‐mediated effects on this susceptibility, we measured the effects of foliage from three plants, soybeans (Glycine max), collards (Brassica oleracea) and water convolvuluses (Ipomoea aquatica), on the susceptibility of larval beet armyworm (Spodoptera exigua) to nucleopolyhedrovirus (NPV), and analysed six foliar chemicals (total phenolics, peroxidase [POD], catalase [CAT], superoxide dismutase [SOD], endochitinase and exochitinase) in the three plants, respectively. The results of exponential modelling indicated that the LD50s (median lethal dose) of NPV to larvae increased with the increase in both phenolics and POD but declined with the increase in four other foliar chemicals, while the opposite trend was found between median lethal time (LT50) of NPV and the six foliar chemicals. This study reveals that phenolics and POD decrease host susceptibility to the entomoviruses and that CAT, SOD, endochitinase and exochitinase increase this susceptibility.
