“…In CL sorghum, differentially expressed genes related with glycerolipid, glicerin metabolism, anthocyanin, phenylpropanoid biosynthesis, limonene and pinene degradation, and circadian rhythm were reported [ 40 ]. DEGs involved in secondary metabolites biosynthesis found in RDA-Seq analysis were mainly represented by mono-/sesquiterpene-/diterpene synthases [ 10 ], phenylalanine ammonia lyases [ 9 ] (Table S7 ).…”

“…In wheat, the pair of lodicules swell and wither leading to glume opening and glume closing at anthesis [ 35 , 36 ]. These processes are due to the water flow into and out of the lodicule cells associated with the accumulation of K + [ 12 , 16 , 37 ], accumulation and transport of calcium in the epidermis and outer parenchymatous cells of lodicules [ 15 , 16 , 18 ], concentration of soluble sugars [ 15 , 38 , 39 ], starch [ 15 , 40 ], signalling by jasmonic acid and its derivatives (JAs) [ 37 , 39 , 40 ], and controlled by K + transporters [ 37 , 39 ], aquaporins [ 36 ] or stimulus associated with pollination [ 8 ]. In sorghum, exogenous MeJA treatments could induce the up- or down- regulation of genes related to starch and sucrose metabolism, alpha-linolenic acid metabolism and plant hormone signal transduction pathways in the plasma cells of sorghum florets, thereby promoting the opening of sorghum florets [ 40 ].…”

Identification of candidate genes responsible for chasmogamy in wheat

Background The flowering biology of wheat plants favours self-pollination which causes obstacles in wheat hybrid breeding. Wheat flowers can be divided into two groups, the first one is characterized by flowering and pollination within closed flowers (cleistogamy), while the second one possesses the ability to open flowers during processes mentioned above (chasmogamy). The swelling of lodicules is involved in the flowering of cereals and among others their morphology, calcium and potassium content differentiate between cleistogamic and non-cleistogamous flowers. A better understanding of the chasmogamy mechanism can lead to the development of tools for selection of plants with the desired outcrossing rate. To learn more, the sequencing of transcriptomes (RNA-Seq) and Representational Difference Analysis products (RDA-Seq) were performed to investigate the global transcriptomes of wheat lodicules in two highly chasmogamous (HCH, Piko and Poezja) and two low chasmogamous (LCH, Euforia and KWS Dacanto) varieties at two developmental stages—pre-flowering and early flowering. Results The differentially expressed genes were enriched in five, main pathways: “metabolism”, “organismal systems”, “genetic information processing”, “cellular processes” and “environmental information processing”, respectively. Important genes with opposite patterns of regulation between the HCH and LCH lines have been associated with the lodicule development i.e. expression levels of MADS16 and MADS58 genes may be responsible for quantitative differences in chasmogamy level in wheat. Conclusions We conclude that the results provide a new insight into lodicules involvement in the wheat flowering process. This study generated important genomic information to support the exploitation of the chasmogamy in wheat hybrid breeding programs.

“…MeJA can also induce flower opening in indica CMS lines with a significant flower opening peak, showing that MeJA has universal applicability in regulating DFOT in hybrid rice production [ 49 ]. Exogenous MeJA has also been reported to promote the DFOT of sorghum, and the promotion effect increases with the increasing concentration of exogenous MeJA [ 50 ]. Therefore, JAs play an important role in crop breeding.…”

The principal goal of rice (Oryza sativa L.) breeding is to increase the yield. In the past, hybrid rice was mainly indica intra-subspecies hybrids, but its yield has been difficult to improve. The hybridization between the indica and japonica subspecies has stronger heterosis; the utilization of inter-subspecies heterosis is important for long-term improvement of rice yields. However, the different diurnal flower-opening times (DFOTs) between the indica and japonica subspecies seriously reduce the efficiency of cross-pollination and yield and increase the cost of indica–japonica hybrid rice seeds, which has become one of the main constraints for the development of indica–japonica hybrid rice breeding. The DFOT of plants is adapted to their growing environment and is also closely related to species stability and evolution. Herein, we review the structure and physiological basis of rice flower opening, the factors that affect DFOT, and the progress of cloning and characterization of DFOT genes in rice. We also analyze the problems in the study of DFOT and provide corresponding suggestions.

“…The ease of studying its diploid genome and the high natural genetic variation offers a rich pool of traits for crop improvement and breeding. Genome assembly and annotation, as well as transcriptomic studies under various conditions such as abiotic stress and pathogen infection, have yielded critical insights into its stress tolerance mechanisms and potential breeding targets [ 10 , 11 , 12 ]. These multifaceted perspectives on S. bicolor , spanning genetics, genomics, and transcriptomics, equip us with a comprehensive understanding of its genetic diversity and its potential for crop improvement.…”

Sorghum bicolor L. is a vital cereal crop for global food security. Its adaptability to diverse climates make it economically, socially, and environmentally valuable. However, soil salinization caused by climate extremes poses a threat to sorghum. This study aimed to identify candidate salt-tolerant genes and single nucleotide polymorphisms (SNPs) by performing a comparative transcriptome analysis on a mutant sorghum line and its wild type. The mutant line was generated through gamma ray exposure and selection for salt tolerance. Phenotypic measurements were taken, followed by mRNA sequencing and variant calling. In this study, potential genes and non-synonymous SNPs associated with salt tolerance were inferred, including LOC8071970, LOC8067721, LOC110430887, LOC8070256, and LOC8056880. These genes demonstrated notable differences in nsSNPs in comparison to the wild type, suggesting their potential roles in salt tolerance. Additionally, LOC8060874 (cyanohydrin beta-glucosyltransferase) was suggested as a key gene involved in salt tolerance due to its possible role in dhurrin biosynthesis under salt stress. In upcoming research, additional reverse genetics studies will be necessary in order to verify the function of those candidate genes in relation to salt stress. In conclusion, this study underscores the significance of investigating salt tolerance mechanisms and the potential key genes associated with salt tolerance in sorghum. Our findings may provide insights for future breeding strategies aimed at enhancing salinity tolerance and crop productivity.
