TL;DR
PbrFEN-1 maintains tip-localized ROS homeostasis to promote pear pollen tube growth, while its repression by self-S-RNase reveals a novel link between DNA metabolism and pear self-incompatibility.
Self-incompatibility (SI) severely restricts breeding efficiency and genetic improvement in cultivated pineapple (Ananas comosus (L.) Merr.), yet its molecular basis remains poorly understood. Here, we investigated the molecular processes associated with gametophytic SI (GSI) and compatible pollination using pineapple...
The rejection of self-incompatible (SI) Brassica pollen is mediated by three signaling branches that function in parallel in the stigma. The recognition of SI pollen by the stigma S-Receptor Kinase (SRK) results in activation of the ARM-Repeat-Containing 1 E3 ubiquitin ligase (ARC1) which mediates the degradation of co...
PavSDJ is a pollen-expressed type III J-protein that binds S-RNase and promotes recruitment of SLFL6 to an S-RNase-associated complex in Prunus, and may function as a general modifier involved in the GSI system of Prunus.
Desiccation tolerance (DT) is a survival trait enabling orthodox seeds to withstand extremely low water content. While some protective factors are characterised, it remains mechanistically obscure. Here, based on PEG-induced DT re-establishment in germinated Brassica napus L. seeds, we investigated the dual functions o...
Artificial microRNA-based gene silencing approach in PM-susceptible Vitis vinifera cv to stably silence the 'Chardonnay' ortholog of AtPMR6, VvPLL3 improves foliar resistance against the PM fungus.
The discovered functional SNP of NMS1 provides a novel theoretical foundation and a valuable sterile genetic resource for hybrid rice breeding and demonstrates that NMS1 plays a crucial role in coordinating tapetal degradation and microspore development in rice.
