“…Leaves of albino mutants have been associated with significantly lower chlorophyll and carotenoid contents than wild-type leaves (Liu et al., 2016a; Liu et al., 2016b). In our study, Chl and carotenoid contents were significantly different between Whs and Grs (Table 1), with Grs having approximately 16 and 17 times that in Whs, respectively.…”

Background Ananas comosus var. bracteatus has high ornamental value due to its chimeric leaves. However, the chimeric trait is very unstable in red pineapple plants, and transcriptional variation between the two types of cells (white/green cells) and the molecular mechanism responsible for their albino phenotype remain poorly understood. Methods Comparative transcriptomic and proteomic analyses of the white parts (Whs) and green parts (Grs) of chimeric leaves were performed. Results In total, 1,685 differentially expressed genes (DEGs) (712 upregulated and 973 downregulated) and 1,813 differentially abundant proteins (DAPs) (1,018 with low abundance and 795 with high abundance) were identified. Based on Gene Ontology (Go) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses, the DEGs were mostly involved in carbon fixation in photosynthetic organisms, porphyrin and chlorophyll metabolism and oxidative phosphorylation, while proteomic analysis revealed that DAPs were mostly related to ribosomes, photosynthesis, photosynthesis antennas, and porphyrin and chlorophyll metabolism. Combined analysis showed increased mRNA levels but low abundance of nine proteins level in Whs /Grs related to photosynthetic pigment and photosynthesis. Transcriptional changes, posttranscriptional regulation and translational alterations of key enzymes involved in chlorophyll biosynthesis and photosynthesis may play important roles in the albino parts of chimeric leaves.

“…As is known to all, heavy ions irradiation is expected to increase mutation frequency and mutation spectrum, characterized by high linear energy transfer (LET) and relative biological effectiveness (RBE) (Zhou et al, 2006).Heavy ion beam has been used on many plants, such as the Artemisia annua (Inthima et al, 2014), chrysanthemum (Yamaguchi et al, 2010), wheat (Liu et al, 2013), Lotus japonicus (Luo et al, 2016), Green wandering jew (Liu et al, 2016) and Arabidopsis (Du et al, 2014;Yoshihiro et al, 2017), etc. In plants, the biological effects of heavy-ion radiation encompassed a wide range of alterations, including developmental abnormalities (Kranz, 1994), chromosomal aberrations (Ritter & Durante, 2010;Kikuchi et al, 2009;Wei et al, 2006) and increased mutation rates (Du et al, 2014).…”

Sweet sorghum [Sorghum bicolor (L.) Moench] is a C 4 plant characterized by a high photosynthetic efficiency and a high biomass-and sugar-yielding crop. However, the current varieties of sweet sorghum cannot meet the rapid growth demand for bio-ethanol production because of its low sugar content in China. To breed novel varieties to provide excellent raw materials for bio-ethanol production, the dry seeds were irradiated by carbon ion beam irradiation with different doses in sweet sorghum, resulting in acquiring an early-maturity mutant at 80 Gy dose, which the growth period was stably shortened for around 20 days compared to wild-type plant. In this paper, we briefly summarized the biological effects induced by carbon ion beam, the characters of early-maturity mutant, and revealed corresponding mechanisms from the point of view of morphological, physiological and molecular levels. In conclusion, there were significant effects on sweet sorghum irradiated by carbon ion beam.

“…While in carbon-fixation reaction, the ATP and NADPH were used to drive the synthesis of organics by a series of enzymatic reactions [10]. Albino seedlings are ideal materials to study photosynthesis [11]. Previous researches on photosynthesis have emphasized on the herbaceous plants mostly whereas only a few reports were found in the woody plants, such as Camellia sinensis [12] and Citrus reticulata [13].…”

Albino Artocarpus heterophyllus Seedlings (AAS) were found in the preliminary investigation by our group and were used as materials for researching. The phenotype of AAS leaves were observed and measured. In parallel, the photosynthetic physiological parameters were determined under different photosynthetically active radiations (PAR). The results suggested that the length, width, area and thickness of AAS leaves were less than normal seedings. Likewise, the net photosynthetic rate, intercellular CO 2 concentration, stomatal conductance and transpiration rate of AAS leaves were not susceptible to PAR in contrast to normal individuals. Furthermore, the transcriptome sequencing technology was performed to clarify the expression of genes related to photosynthesis. It is as expected that numerous down-regulated genes were found in the synthesis of photosynthetic pigments, as well as the pathways of photosynthesis - antenna proteins, photoreaction and carbon fixation reaction of AAS leaves. Compared to other albino plants, AAS have a longer life span and more stable phenotypic traits with larger leaves, which could provide ideal materials for investigating photosynthesis of woody plants.
