“…3) clearly demonstrate that the sun‐exposed peel of red ‘Anjou’ has a higher photoprotective capacity than that of green ‘Anjou’. This is consistent with the results previously obtained on pods of Bauhinia variegate (Smillie and Hetherington 1999), and leaves of red‐osier dogwood ( Cornus stolonifera ) (Feild et al 2001) and Lactuca sativa (Neill and Gould 2003). The sun‐exposed peel of red ‘Anjou’ and green ‘Anjou’ had similar xanthophyll cycle pool size on a chlorophyll basis and de‐epoxidation state throughout fruit development (Fig.…”

“…Several studies indicate that anthocyanins play a physiological role in protecting leaves from high light damage (Close et al 2001, Hoch et al 2001, Hughes and Smith 2007, Hughes et al 2005, 2007). Anthocyanins can shield the chloroplast from excess light by absorbing blue‐green light (Feild et al 2001, Smillie and Hetherington 1999). Anthocyanins may also directly scavenge active oxygen species (Gould et al 2002, Neill and Gould 2003, Yamasaki et al 1996).…”

Photoprotective function of anthocyanins along with xanthophyll cycle and antioxidant system in fruit peel was investigated in red 'Anjou' vs green 'Anjou' pear (Pyrus communis) during fruit development and in response to short-term exposure to high light. The sun-exposed peel of red 'Anjou' had higher maximum quantum yield of photosystem II (F(V)/F(M)) than that of green 'Anjou' and both the sun-exposed peel and the shaded peel of red 'Anjou' had smaller decreases in F(V)/F(M) after 2-h high light (photon flux density of 1500 mumol m(-2) s(-1)) treatment than those of green 'Anjou'. At the middle and late developmental stages, the xanthophyll cycle pool size on a chlorophyll basis, the activity of superoxide dismutase, ascorbate peroxidase (APX), monodehydroascorbate reductase (MDAR), dehydroascorbate reductase (DHAR) and glutathione reductase (GR) and the level of reduced ascorbate and total ascorbate pool in the sun-exposed peel were either the same or lower in red 'Anjou' than in green 'Anjou', whereas the xanthophyll cycle pool size on a chlorophyll basis and the activity of APX, catalase, MDAR, DHAR and GR in the shaded peel were higher in red 'Anjou' than in green 'Anjou'. It is concluded that red 'Anjou' has a higher photoprotective capacity in both the sun-exposed peel and the shaded peel than green 'Anjou'. While the higher anthocyanin concentration along with the larger xanthophyll cycle pool size and the higher activity of some antioxidant enzymes may collectively contribute to the higher photoprotective capacity in the shaded peel of red 'Anjou', the higher photoprotective capacity in the sun-exposed peel of red 'Anjou' is mainly attributed to its higher anthocyanin concentration.

“…In particular, using the automated oxygen radical absorbance capacity to determine the antioxidant capacity of 14 anthocyanins, Wang et al (1997) found that the capacities of cyanidin‐3‐glucoside to scavenge oxygen radicals was 3.5 times stronger than α‐tocopherol. Some in vivo experiments have suggested that anthocyanins may act both as a sunscreen because they strongly absorb green‐blue light, and as a scavenger of ROS (Gould et al 1995, Hughes et al 2005, Neill and Gould 2003, Smillie and Hetherington 1999, Steyn et al 2002). However, Lee et al (2003), in a survey of senescing leaves from 89 woody species, found no evidence of photoprotection by anthocyanins, based on predawn measurements of photosystems II (PSII) photochemical efficiency.…”

Protective effect of supplemental anthocyanins on Arabidopsis leaves under high light

Ten anthocyanin components have been detected in roots of purple sweet potato (Ipomoea batatas Lam.) by high-performance liquid chromatography coupled to diode array detection and electrospray ionization tandem mass spectrometry. All the anthocyanins were exclusively cyanidins or peonidin 3-sophoroside-5-glucosides and their acylated derivatives. The total anthocyanin content in purple sweet potato powder obtained by solid-phase extraction was 66 mg g(-1). A strong capacity of purple sweet potato anthocyanins (PSPA) to scavenge reactive oxygen species (superoxide, hydroxyl radical) and the stable 1,1-diphenyl-2-picrylhydrazyl organic free radical was found in vitro using the electron spin resonance technique. To determine the functional roles of anthocyanins in leaves in vivo, for the first time, supplemental anthocyanins were infiltrated into leaves of Arabidopsis thaliana double mutant of the ecotype Landsberg erecta (tt3tt4) deficient in anthocyanin biosynthesis. Chlorophyll fluorescence imaging showed that anthocyanins significantly ameliorated the inactivation of photosystems II during prolonged high-light (1300 micromol m(-2) s(-1)) exposure. Comet assay of DNA revealed an obvious role of supplemental PSPA in alleviating DNA damage by high light in leaves. Our results suggest that anthocyanins could function in vitro and in vivo to alleviate the direct or indirect oxidative damage of the photosynthetic apparatus and DNA in plants caused by high-light stress.

“…(Figure 1c and Tables 1, 2), which needed to be investigated further. Such protective roles of this pigment, both against plant diseases (Dixon 2001;Bovy et al 2007) and physical stresses (Smillie and Hetherington 1999) were conveyed earlier. In addition, the role of this pigments was also reported, by Lu et al (2017), Rosado-Á lvarez et al 2014, Liu et al (2013), Maddox et al (2010), Treutter (2006), Steyn et al (2002) and Nicholson and Hammerschmidt (1992), in safeguarding the plant growth and development.…”

Single plant selection for improving root rot disease (Phytophthora medicaginis) resistance in Chickpeas (Cicer arietinum L.)

The root rot caused by Phytophthora medicaginis is a major disease of chickpea in Australia. Grain yield loss of 50 to 70% due to the disease was noted in the farmers' fields and in the experimental plots, respectively. To overcome the problem, resistant single plants were selected from the National Chickpea Multi Environment Trials (NCMET)-Stage 3 (S3) of NCMET-S1 to S3, which were conducted in an artificially infected phytophthora screening field nursery in the Hermitage Research Station, Queensland. The inheritance of resistance of these selected resistant single plants were tested in the next generation in three different trials, (1) at seedling stage in a shade house during the offseason, (2) as bulked single plants and (3) as individual single plants in the disease screening filed nursery during the next season. The results of the tests showed that many of the selected single plants had higher level of resistance and seed yield (P \ 0.05) than the best resistant cultivars used as checks. The single plants with bidirectional expression of anthocyanin pigment, both at the shoot apex and at the base of stem, showed higher level of resistance than plants without it. The results also indicated certain level of heterozygosityinduced heterogeneity, which could cause higher levels of susceptibility, if the selected single plants were not screened further for the disease resistance in advanced generation/s. The genetics of resistance to PRR disease was confirmed as quantitative in nature.
