“…HaCYC2c was overexpressed after an insertion into the HaNDUA2 promoter region to generate the sunflower long petal mutant ( lpm ) in which the abnormal elongation of the disc floret corolla and stamen abortion at an early stage of floral organ development was observed [ 82 ]. Furthermore, the floret symmetry changed from radial symmetry to bilateral symmetry, thus transforming the disc florets into ray florets.…”

“…Furthermore, the floret symmetry changed from radial symmetry to bilateral symmetry, thus transforming the disc florets into ray florets. The overexpression of HaCYC2c and its control of HaNDUA2 through transcriptional recognition may be an important regulatory node for floret type and functional differentiation in Helianthus , which was associated with maintaining the balance between the pollinator recruitment ability and the fertility of disc florets [ 82 ].…”

CYCLOIDEA (CYC)-like genes belong to the TCP transcription factor family and play important roles associated with flower development. The CYC-like genes in the CYC1, CYC2, and CYC3 clades resulted from gene duplication events. The CYC2 clade includes the largest number of members that are crucial regulators of floral symmetry. To date, studies on CYC-like genes have mainly focused on plants with actinomorphic and zygomorphic flowers, including Fabaceae, Asteraceae, Scrophulariaceae, and Gesneriaceae species and the effects of CYC-like gene duplication events and diverse spatiotemporal expression patterns on flower development. The CYC-like genes generally affect petal morphological characteristics and stamen development, as well as stem and leaf growth, flower differentiation and development, and branching in most angiosperms. As the relevant research scope has expanded, studies have increasingly focused on the molecular mechanisms regulating CYC-like genes with different functions related to flower development and the phylogenetic relationships among these genes. We summarize the status of research on the CYC-like genes in angiosperms, such as the limited research conducted on CYC1 and CYC3 clade members, the necessity to functionally characterize the CYC-like genes in more plant groups, the need for investigation of the regulatory elements upstream of CYC-like genes, and exploration of the phylogenetic relationships and expression of CYC-like genes with new techniques and methods. This review provides theoretical guidance and ideas for future research on CYC-like genes.

“…Presumed promoters of upregulated genes in response to NaCl treatment were found to harbor the consensus ACGTGTTCG (P value of 4.0E -20 ), which represents an ABRE and potential CAMTA-binding site (Kaplan et al, 2006;Finkler et al, 2007b;Shkolnik et al, 2019) and CTGCCGCG (P value of 2.7E -18 ), which represents a CGCG-core motif that is present in CAMTA-binding elements (Yang and Poovaiah, 2002;Han et al, 2006). In response to CaCl 2 treatment, the presumed upregulated gene promoters were found to contain the consensus TAGGCCCA (P value of 5.1E -23 ), which represents a regulatory element group cis-element (Yamamoto et al, 2007) and GGTCCCGA (P value of 2.7E -16 ), which is classified as a CYCLOIDEA(cyc)-binding motif, has been shown to be involved in the regulation of floral development (He et al, 2022), and could be bound by TCP24, a TF that negatively regulates secondary cell-wall thickening (Wang et al, 2015). Downregulated presumed gene promoters identified in response to CaCl 2 treatment were found to harbor the consensus GCCTGCAC (P value of 3.8E -15 ), reported to be the signature binding sequence of the nitrogen-control NtcA TFs in the unicellular cyanobacterium Synechococcus (Gunawardana and Herath, 2022), and a second motif with a consensus CGACGCGG (P value of 1.4E -14 ) which represents an ABRE and CAMTA-binding motif (Kaplan et al, 2006;Finkler et al, 2007b).…”

Calcium is known to improve seed-germination rates under salt stress. We investigated the involvement of calcium ions (Ca2+) in regulating HIGH AFFINITY K+ TRANSPORTER 1 (HKT1;1), which encodes a Na+/K+ transporter, and its post-translational regulator TYPE 2C PROTEIN PHOSPHATASE 49 (PP2C49), in germinating Arabidopsis thaliana seedlings. Germination rates of hkt1 mutant seeds under salt stress remained unchanged by CaCl2 treatment in wild-type Arabidopsis, whereas pp2c49 mutant seeds displayed improved salt-stress tolerance in the absence of CaCl2 supplementation. Analysis of HKT1;1 and PP2C49 promoter activity revealed that CaCl2 treatment results in radicle focused expression of HKT1;1 and reduction of the native radicle-exclusive expression of PP2C49. Ion content analysis indicated that CaCl2 treatment improves K+ retention in germinating wild-type seedlings under salt stress, but not in hkt1 seedlings. Transgenic seedlings designed to exclusively express HKT1;1 in the radicle during germination displayed higher germination rates under salt stress than the wild type in the absence of CaCl2 treatment. Transcriptome analysis of germinating seedlings treated with CaCl2, NaCl, or both revealed 118 upregulated and 94 downregulated genes as responsive to the combined treatment. Bioinformatics analysis of the upstream sequences of CaCl2 NaCl treatment responsive upregulated genes revealed the abscisic acid response element CACGTGTC, a potential CaM binding transcription activator binding motif, as most prominent. Our findings suggest a key role for Ca2+ in mediating salt-stress responses during germination by regulating genes that function to maintain Na+ and K+ homeostasis, which is vital for seed germination under salt stress.

Opportunities and Challenges of Castor Bean (Ricinus communis L.) Genetic Improvement

et al. 2023

View full text Add to dashboard Cite

Castor bean (Ricinus communis L.) originated in East Africa and then diffused to warm-temperate, subtropical, and tropical regions of the world. The high lipid content in the castor beans is extracted for use in pharmaceutical and industrial applications. The castor oil lipid profile is naturally composed of 90% ricinoleic acid and the remaining 10% is mainly composed of linoleic, oleic, stearic, and linolenic fatty acids. The highly toxic compound ricin within the seeds is insoluble in oil, making castor oil free from this toxin and safe to use for industrial and cosmetic applications. Among the main uses of castor oil are reported industrial uses such as component for lubricants, paints, coatings, polymers, emulsifiers, cosmetics, and medicinal uses as a laxative. There is also significant commercial potential for utilization of the whole castor bean plant such as animal feed, fertilizer, biofuel, and also for phytoremediation. Several breeding programs have been planned to improve the castor’s characteristics needed for its current or potential uses. In this review, after summarizing data on castor bean agronomy and uses, we focus on the main advances in Castor bean classical and biotechnological breeding programs, underlining the high potential of this oil crop. In particular, the main challenges of castor breeding programs are to increase yield, mainly through the selection of growth habits allowing mechanized harvest, and beneficial compound content, mainly the oil, and to decrease the toxic compounds content, mainly ricin.
