“…The Chl a/b ratio value was 2.11, confirming the high content of Chl a characteristic of heliophytic species. The Chl a/b ratio is directly related not only to light but also to soil nitrogen availability [ 36 ]. Biological properties shown by chlorophylls and their derivatives consistent with cancer prevention include antioxidant and antimutagenic activity.…”

A method using high-performance liquid chromatography coupled with a photodiode array detector was proposed for the rapid characterization of different phenolic constituents from the extracts of Atriplex mollis aerial parts. Atriplex species are known for their multiple biological activities, but no information is available in the literature about A. mollis. With the aim to firstly characterize the main secondary metabolites of this plant, so as to orient better the biological evaluation, we applied three different extraction procedures and compared the chromatographic results. Microwave-assisted extraction gave the best yield and recovery of important compounds such as gallic acid, catechin, chlorogenic acid, p-OH benzoic acid, rutin, sinapinic acid, t-ferulic acid, naringenin and benzoic acid. These constituents belong to three important chemical classes: phenolic acids, flavonoids and monoterpenes. Color evaluation and analysis of chlorophylls (a and b) and carotenoids complete the preliminary profile of this plant. From these analyses, Atriplex mollis is a source of bioactive compounds (especially rutin, t-ferulic acid and gallic acid) and could be recommended as a plant of phyto-pharmaceutical relevance, opening new perspectives on this salt-tolerant plant.

“…C ab was two‐fold lower in plants of steppe and desert steppe than in plants of forest steppe. In addition, the ratio of chlorophyll a/b markedly decreased from forest to desert steppe, which indicates a restructuring of light‐capturing chlorophyll complexes with latitude (Ivanov et al ., ). Remarkably, in C 4 plants of desert steppe, C ab and the ratio of chlorophyll a/b were as high as in plants of forest steppe (Fig.…”

Quantitative mesophyll parameters rather than whole‐leaf traits predict response of C₃ steppe plants to aridity

We studied the impact of aridity on leaf and mesophyll traits in dominant and very abundant plant species of Eurasian steppe plant communities. We covered a 500-km latitudinal gradient across three vegetation zones in the Volga region of southern European Russia. Whole-leaf traits, volumetric fractions of leaf tissues, quantitative parameters of photosynthetic cells and chloroplasts, and chlorophyll, carbon (C) and nitrogen (N) contents were analyzed and related to plant functional type (PFT), type of mesophyll anatomy, phylogeny and climate aridity. The proportions of prevailing PFTs in the communities, such as C monocots, C dicots with dorsiventral and isopalisade anatomy and C dicots, changed with increasing aridity which influenced the whole-leaf parameters and tissue composition in the leaf. Leaf mass per unit area and leaf thickness slightly increased along the aridity gradient, but the most significant changes were observed in the mesophyll. Mesophyll cell surface area, chloroplast number and chloroplast surface area per unit leaf area were higher in C plants growing in the desert steppe compared with those of the forest steppe, while chlorophyll content per single chloroplast and per unit N content as well chlorophyll a/b ratio decreased. Our results identify a suite of mesophyll traits as a typical 'syndrome' of increasingly drought-adapted steppe plants.

“…Количественное содержание хлорофилла b в тканях седьмого узла в момент цветения составляет 1.7 мг/г или 35.4% от общего количества зеленых пигментов, по мере формирования зерновки снижается до 0.75 − 0.52 мг/г. Из литературных данных известно, что повышение доли хлорофилла b в фотосинтезирующих тканях свидетельствует о повышении их светособирающей способности в области дальнего красного света (Ivanov et al, 2013). Следовательно, сооотношение хлорофиллов a и b определяет адаптационную способность к изменениям освещенности, позволяя скоординировать распределение ресурсов для достижения и поддержания оптимальных скоростей фотосинтеза.…”
