Methyl Jasmonate (MeJA) Promotes the Self-Pollen Tube Growth of by Regulating Lignin Biosynthesis.

Self-incompatibility (SI) poses a significant reproductive barrier, severely impacting the yield, quality, and economic value of . In this study, methyl jasmonate (MeJA) was employed as an exogenous stimulus to alleviate SI in . The research findings revealed that an exogenous dose of 1000 μmol·L MeJA enhanced the germination and tube growth of self-pollen and greatly improved ovule penetration (18.

Unilateral cross-incompatibility between and provides new insights for hybridization in spp.

was used to cross with to improve the resistance of oil camellia anthracnose. However, unilateral cross-incompatibility (UCI) between and was found during the breeding process. Five cultivars and four materials were tested to confirm the UCI between and .

Transcriptome and Anatomical Comparisons Reveal the Effects of Methyl Jasmonate on the Seed Development of .

Seed is a major storage organ that determines the yield and quality of (). Methyl jasmonate (MeJA) is a signaling molecule involved in plant growth and development. However, the role of MeJA in the development of seeds remains a mystery.

Integration of semi- assays and multi-omics data reveals the effect of galloylated catechins on self-pollen tube inhibition in .

oil extracted from the seeds of Abel. is a popular and high-quality edible oil, but its yield is limited by seed setting, which is mainly caused by self-incompatibility (SI). One of the obvious biological features of SI plants is the inhibition of self-pollen tubes; however, the underlying mechanism of this inhibition in is poorly understood.

Chromosome-level genome of Camellia lanceoleosa provides a valuable resource for understanding genome evolution and self-incompatibility.

The section Oleifera (Theaceae) has attracted attention for the high levels of unsaturated fatty acids found in its seeds. Here, we report the chromosome-scale genome of the sect. Oleifera using diploid wild Camellia lanceoleosa with a final size of 3.
