Editorial: Regulation of ovule and seed development
Notice bibliographique
Résumé
Current research topic delves into subjects ranging from fundamental mechanisms of reproductive biology to practical strategies for enhancing crop resilience under environmental stresses. Since seed-based traits are pivotal in maintaining and conferring biodiversity, insights into their development and adaptation are critical to cope with issues like climate change, food scarcity, and e;ective management of underutilized marginal lands.This focused issue presents four unique contributions, each o;ering insights into di;erent aspects of plant reproduction and seed-related traits. While some of these studies align directly with ovule and seed development, others provide complementary perspectives, broadening the narrative of the topic.Seed development via sexual reproduction essentially relies on the successful delivery of male gametes to fuse with egg cell residing in the embryo sac of female gametophyte. Hence, coordinated and precise development of male and female gametes is essential in the process. Here, Cui et al. discuss the molecular mechanisms behind microsporogenesis and micro-gametogenesis with references to recent relevant studies. The authors highlight the crucial role of auxin in defining archesporial cell specialization and the importance of premitotic microspore maturation and o;er prospects for future studies.The relevance of environmental stresses to seed development is explored by Erfatpour et al., who examined the impacts of climate change on reproductive success across crop species. By integrating evidence on the e;ects of temperature, drought, and salinity, they highlight the vulnerability of ovule and seed formation to abiotic stress. This work underscores the need for climate resilient crops and adaptive agricultural practices. Importantly, the authors also propose future research directions, such as identifying genetic pathways that can be harnessed for breeding stress-tolerant crop varieties.Expanding the focus to molecular mechanisms, Yan et al. investigate the HACD gene family in cotton (Gossypium hirsutum). Their study identifies GhHACD2 as a key regulator of very long-chain fatty acid biosynthesis, a trait that influences cottonseed oil content and quality. The authors, however, also observed its higher expression in the low oil-producing genotype at the critical oil accumulation phase of development as compared to that in the high oilproducing lines. They corroborated their observation with its heterologous expression in yeast and recorded a significant reduction in total oil content. This finding is first of its kind regarding the role of an HACD member in the regulation of cottonseed oil content.The study by Zhou et al. explores how karst-specific environmental stresses-drought, calcium salts, and pH variations-a;ect the germination and growth of alfalfa (Medicago sativa L.), an important forage crop of the Karst region. The study observed that the root systems of the seedlings are more sensitive to the assessed abiotic stresses. The findings made in the study o;er a reference for screening and selection of suitable plants to cultivate in the Karst region.Collectively, the four studies presented in the Research Topic focused on ovule and seed spanning from gametophyte development to seed germination. By addressing diverse aspects of ovule and seed biology, they contribute significantly to advancing this critical field. The insights presented here are expected to contribute future research directions in this important research field by integrating molecular biology, genetics, and applied agronomy to develop resilient crop systems.We are grateful to the authors and reviewers who contributed their expertise to this collection, enriching our understanding of the field relevant to ovule and seed development and its broader future prospects.

Imitation des enseignantsNi prévalence calibrée, ni vérité terrain. Validation humaine à venir. Le volet Gemma est une étiquette directe du modèle pour chaque travail de la base, lue sur la notice réduite au titre. Le volet Codex est un classifieur appris des 10 348 étiquettes directes de Codex et calibré sur les taux pondérés de l'échantillon; les champs sans appui suffisant ne portent aucun appel Codex. Le mode candidate est l'union des deux volets; le consensus est leur intersection. Ces sorties portent le statut machine_predicted_unvalidated et ne sont pas des étiquettes humaines.
