Abstract
Garlic is cultivated worldwide for the value of its bulbs, but its cultivation is challenged by the infertility of commercial cultivars and the accumulation of pathogens over time, which occurs as a consequence of vegetative (clonal) propagation. In this review, we summarize the state of the art of garlic genetics and genomics, highlighting recent developments that will lead to its development as a modern crop, including the restoration of sexual reproduction in some garlic strains. The set of tools available to the breeder currently includes a chromosome-scale assembly of the garlic genome and multiple transcriptome assemblies that are furthering our understanding of the molecular processes underlying important traits like the infertility, the induction of flowering and bulbing, the organoleptic properties and resistance to various pathogens.

Pathogenesis-related protein-4 (PR-4) gene family in Qingke (Hordeum vulgare L. var. nudum): genome-wide identification, structural analysis and expression profile under stresses. Mol Biol Rep 2022; 49:9397-9408. [PMID: 36008607 DOI: 10.1007/s11033-022-07794-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/16/2022] [Accepted: 07/11/2022] [Indexed: 11/29/2022]
Abstract
BACKGROUND Pathogenesis-related (PR) proteins are active participants of plant defense against biotic and abiotic stresses. The PR-4 family features a Barwin domain at the C-terminus, which endows the host plant with disease resistance. However, comprehensive analysis of PR-4 genes is still lacking in Qingke (Hordeum vulgare L. var. nudum). METHODS AND RESULTS Herein, a total of four PR-4 genes were identified from the genome of Qingke through HMM profiling. Devoid of the chitin-binding domain, these 4 proteins were grouped as class II PR-4s. Phylogenic analysis revealed that 127 PR-4s from 47 species were clustered into 3 major groups, among which the four Qingke PR-4s were claded into group I. Analysis of gene structure demonstrated that no intron was found in 3 out of the 4 Qingke PR-4s, and HOVUSG0928500 was the only gene contained one intron. An array of cis-acting motifs were detected in promoters of Qingke PR-4 genes, including elements associated with hormone response, light response, stress response, growth and development processes and binding sites of transcription factors, implying their diverse role. Expression profiling confirmed that Qingke PR-4s were involved in defense response against drought, cold and powdery mildews infection, and transcription of HOVUSG1974300 and HOVUSG5705400 was differentially regulated by MeJA and SA. CONCLUSION Findings of the study provided insights into the genetic basis of the PR-4 family genes, and would promote further investigation on protein function and utilization.

Wang L, Xu Z, Yin W, Xu K, Wang S, Shang Q, Sa W, Liang J, Wang L. Genome-wide analysis of the Thaumatin-like gene family in Qingke ( Hordeum vulgare L. var. nudum) uncovers candidates involved in plant defense against biotic and abiotic stresses. FRONTIERS IN PLANT SCIENCE 2022; 13:912296. [PMID: 36061804 PMCID: PMC9428612 DOI: 10.3389/fpls.2022.912296] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 04/05/2022] [Accepted: 07/29/2022] [Indexed: 06/15/2023]
Abstract
Thaumatin-like proteins (TLPs) participate in the defense responses of plants as well as their growth and development processes, including seed germination. Yet the functioning of TLP family genes, in addition to key details of their encoded protein products, has not been thoroughly investigated for Qingke (Hordeum vulgare L. var. nudum). Here, a total of 36 TLP genes were identified in the genome of Qingke via HMM profiling. Of them, 25 TLPs contained a signal peptide at the N-terminus, with most proteins predicted to localize in the cytoplasm or outer membrane. Sequence alignment and motif analysis revealed that the five REDDD residues required for β-1,3-glucanase activity were conserved in 21 of the 36 Qingke TLPs. Phylogenetically, the TLPs in plants are clustered in 10 major groups. Our analysis of gene structure did not detect an intron in 15 Qingke TLPs whereas the other 21 did contain 1-7 introns. A diverse set of cis-acting motifs were found in the promoters of the 36 TLPs, including elements related to light, hormone, and stress responses, growth and development, circadian control, and binding sites of transcription factors, thus suggesting a multifaceted role of TLPs in Qingke. Expression analyses revealed the potential involvement of TLPs in plant defense against biotic and abiotic stresses. Taken together, the findings of this study deepen our understanding of the TLP family genes in Qingke, a staple food item in Tibet, which could strengthen future investigations of protein function in barley and its improved genetic engineering.
