Single-molecule long-read sequencing of the full-length transcriptome of Rhododendron lapponicum L.

Rhododendron lapponicum L. is a familiar ornamental plant worldwide with important ornamental and economic value. However, a full-length R.

Identification of pre-fertilization reproductive barriers and the underlying cytological mechanism in crosses among three petal-types of Jasminum sambac and their relevance to phylogenetic relationships.

Crosses among single-, double- and multi-petal jasmine cultivars (Jasminum sambac Aiton) are unable to easily generate hybrids. To identify the reproductive barriers restricting hybrid set, dynamic changes in jasmine pollen viability and pistil receptivity were compared at different flowering stages. Pollen-pistil interactions in six reciprocal crosses were also investigated to characterize pollen-stigma compatibility.

Transcriptome-based discovery of pathways and genes related to resistance against Fusarium head blight in wheat landrace Wangshuibai.

Background: Fusarium head blight (FHB), caused mainly by Fusarium graminearum (Fg) Schwabe (teleomorph: Gibberellazeae Schwble), brings serious damage to wheat production. Chinese wheat landrace Wangshuibai is one of the most important resistance sources in the world. The knowledge of mechanism underlying its resistance to FHB is still limited.

A fast-neutron induced chromosome fragment deletion of 3BS in wheat landrace Wangshuibai increased its susceptibility to Fusarium head blight.

Fusarium head blight (FHB), also called wheat scab, is an important disease in warm and humid regions worldwide, which not only reduces crop yield and grain quality, but also is a major safety concern in food and feed production due to mycotoxin contamination. Growing wheat cultivars with FHB resistance is one of the most economical and effective means to control the disease. Chinese wheat landrace Wangshuibai is an important resistant source from southern China.
