One hypothesized driver of this dominance is grasses' facility for grain dispersal and rapid seedling establishment. Dispersal and establishment are aided by the awned lemma - a modified bract associated with grass flowers. Awns have diverse forms, many proposed functions, and have been gained and lost repeatedly in grass evolution. Here we hypothesize that the evolution of awn emergence is underpinned by deep conservation of developmental genes. Awns are likely homologous to leaf blades. Because leaf blades are essential, every grass species likely has a latent developmental program available for awn development. This developmental program may be repeatedly reactivated in lemmas, resulting in the frequent appearance of awns. Because awns are inessential, they can be lost and modified without dire consequences to fitness, resulting in the frequent loss and diversity of awns. Replicated awn evolution reveals how developmental conservation can potentiate the evolution of diversity. Awns also present a powerful opportunity to dissect mechanisms of leaf development.</div></div>","PeriodicalId":11003,"journal":{"name":"Current opinion in plant biology","volume":"82 ","pages":"Article 102663"},"PeriodicalIF":8.3,"publicationDate":"2024-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142643728","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These studies point to the challenges in the process as HNT tolerance has so far been found only in non-adapted varieties, and no known modern cultivar bred in the United States is able to withstand exposure to HNT during the reproductive stage. At the same time, identification of the tolerant genotypes enabled genomics, opened up tortuous but promising approaches for breeding, and showed a path for gene editing towards HNT tolerance.

Using scRNA-seq, the transcriptome landscape of individual plant cells along with their lineages and regulatory interactions can be unraveled. Moreover, coupling scRNA-seq with spatial transcriptomics provides spatially resolved gene expression and insights into cell-to-cell interactions. In addition, the chromatin accessibility assays can discover the regulatory regions governing abiotic stress responses. An integrated multi-omics approach can facilitate discovery of cell-type-specific GRNs to reveal the key components that coordinate adaptive responses to different stresses.

Currently, one of the most effective mechanisms of root defense involves the root extracellular trap (RET) that is produced at the tip of the root. The RET consists of root cap–derived cells embedded in mucilaginous secretions containing cell wall–derived polysaccharides, defense-related (glyco)proteins, phytoalexins, histones, and extracellular DNA (eDNA).

This molecular stealth hypothesis for fungal pathogenicity has repeatedly been tested by mutating single or multiple chitin deacetylase genes, supporting the hypothesis but simultaneously suggesting additional roles for chitin deacetylation in virulence, such as surface attachment and sensing, host tissue penetration and colonization, as well as spore formation, stabilization, and germination.
