Seed number per fruit is an important yield trait in <jats:italic>C. oleifera<\/jats:italic>. Ovule abortion is generally observed in <jats:italic>C. oleifera<\/jats:italic> and significantly decreases the seed number per fruit. However, the mechanisms of ovule abortion remain poorly understood at present. Single-cell RNA sequencing (scRNA-seq) was performed using mature ovaries of two <jats:italic>C. oleifera<\/jats:italic> varieties with different ovule abortion rates (OARs). In total, 20,526 high-quality cells were obtained, and 18 putative cell clusters were identified. Six cell types including female gametophyte, protoxylem, protophloem, procambium, epidermis, and parenchyma cells were identified from three main tissue types of ovule, placenta, and pericarp inner layer. A comparative analysis on scRNA-seq data between high- and low-OAR varieties demonstrated that the overall expression of <jats:italic>CoSWEET<\/jats:italic> and <jats:italic>CoCWINV<\/jats:italic> in procambium cells, and <jats:italic>CoSTP<\/jats:italic> in the integument was significantly upregulated in the low-OAR variety. Both the infertile ovule before pollination and the abortion ovule producing after compatible pollination might be attributed to selective abortion caused by low sugar levels in the apoplast around procambium cells and a low capability of hexose uptake in the integument. Here, the first single-cell transcriptional landscape is reported in woody crop ovaries. Our investigation demonstrates that ovule abortion may be related to sugar transport in placenta and ovules and sheds light on further deciphering the mechanism of regulating sugar transport and the improvement of seed yield in <jats:italic>C. oleifera<\/jats:italic>.<\/jats:p>","DOI":"10.3389\/fpls.2024.1274013","type":"journal-article","created":{"date-parts":[[2024,2,2]],"date-time":"2024-02-02T04:48:45Z","timestamp":1706849325000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":7,"title":["Single-cell RNA-seq reveals a link of ovule abortion and sugar transport in Camellia oleifera"],"prefix":"10.3389","volume":"15","author":[{"given":"Songzi","family":"Zhao","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jun","family":"Rong","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2024,2,2]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"675","DOI":"10.1007\/s10265-010-0400-z","article-title":"Selective embryo abortion in a perennial tree-legume: a case for maternal advantage of reduced seed number per fruit","volume":"124","author":"Arathi","year":"2011","journal-title":"J.
