A Golgi vesicle-membrane-localized cytochrome B561 regulates ascorbic acid regeneration and confers Verticillium wilt resistance in cotton.

Ascorbic acid (AsA) serves as a key antioxidant involved in the various physiological processes and against diverse stresses in plants. Due to the insufficiency of AsA de novo biosynthesis, the AsA regeneration is essential to supplement low AsA synthesis rates. Redox reactions play a crucial role in response to biotic stress in plants; however, how AsA regeneration participates in hydrogen peroxide (HO) homeostasis and plant defense remains largely unknown.

Re-localization of a repeat-containing fungal effector by apoplastic protein Chitinase-like 1 blocks its toxicity.

A fungal effector that is toxic to plant cells was identified in Verticillium dahliae. The effector contains a non-canonical Common in several Fungal Extracellular Membrane proteins (CFEM) domain, a tandem repeat region consisting of four 14-amino acid repeats rich in proline, and a C-terminal region, thus is designated V. dahliae tetrapeptide repeat protein (VdTRP).

Identification of a gene expression signature of vascular invasion and recurrence in stage I lung adenocarcinoma via bulk and spatial transcriptomics.

Microscopic vascular invasion (VI) is predictive of recurrence and benefit from lobectomy in stage I lung adenocarcinoma (LUAD) but is difficult to assess in resection specimens and cannot be accurately predicted prior to surgery. Thus, new biomarkers are needed to identify this aggressive subset of stage I LUAD tumors. To assess molecular and microenvironment features associated with angioinvasive LUAD we profiled 162 resected stage I tumors with and without VI by RNA-seq and explored spatial patterns of gene expression in a subset of 15 samples by high-resolution spatial transcriptomics (stRNA-seq).
