The structure of chromatin, a complex of DNA and proteins, directly influences the accessibility of genes to the transcriptional machinery. The different signaling pathways and transcription factors involved in the transmission of information from the receptors to the nucleus have been readily explored, but not so much for the specific mechanisms employed by the cell to ultimately instruct the chromatin changes necessary for a fast and robust transcription activation, specifically for plant hormone responses.

The meristem determinacy <em>per se</em> is hierarchically complex and context-dependent for the successively emerged meristems, representing a crucial mechanism in shaping the complexity of the shoot branching. In addition, we have highlighted that two key components of axillary meristem developmental programs may have been co-opted in controlling flower/ear number of an axillary inflorescence in legumes/maize, hinting at the diversification of axillary-meristem-patterning programs in different lineages. This begs the question how axillary meristem patterning programs may have diversified during plant evolution and hence helped shape the rich variation in shoot branching systems.</p></div>","PeriodicalId":11003,"journal":{"name":"Current opinion in plant biology","volume":null,"pages":null},"PeriodicalIF":8.3,"publicationDate":"2024-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141450025","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Dunal) is a versatile medicinal plant of Solanaceae family, renowned for its potent therapeutic properties, due to which it is extensively used in Indian traditional systems of medicine such as Ayurveda. The medicinal properties are attributed to specialized metabolites known as withanolides, which are chemically triterpenoid steroidal lactones. Despite their significance, the biosynthetic pathway of withanolides remains poorly understood. It is hypothesized that withanolides are synthesized through the universal sterol pathway, wherein sterol precursors undergo various biochemical modifications such as hydroxylation, oxidation, cyclization, and glycosylation, yielding a diverse array of downstream withanolides and withanosides. Consequently, comprehending the biosynthetic pathway of withanolides is crucial to facilitate advancements in withanolides productivity through metabolic engineering or synthetic biology approaches. This article aims to provide an update on the efforts made toward understanding withanolides formation and regulation and highlights gaps and approaches to elucidate the withanolides biosynthesis in <em>W. somnifera</em>.</p></div>","PeriodicalId":11003,"journal":{"name":"Current opinion in plant biology","volume":null,"pages":null},"PeriodicalIF":9.5,"publicationDate":"2024-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141326187","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
