RNA-guided CRISPR/Cas9 technology has been developed for gene/genome editing (GE) in organisms across kingdoms. However, in planta delivery of the two core GE components, Cas9 and small guide RNA (sgRNA), often involves time-consuming and labor-intensive production of transgenic plants. Here we show that Foxtail mosaic virus, a monocot- and dicot-infecting potexvirus, can simultaneously express Cas9, sgRNA, and an RNAi suppressor to efficiently induce GE in Nicotiana benthamiana through a transgenic plant-free manner.

Background/objectives: The balanced regulation of innate immunity plays essential roles in rhizobial infection and the establishment and maintenance of symbiosis. The evolutionarily conserved cell death suppressor Bax inhibitor-1 plays dual roles in nodule symbiosis, providing a valuable clue in balancing immunity and symbiosis, while it remains largely unexplored in the legume .

Methods/results: In the present report, the gene family of was identified and characterized.

Chemotherapy remains the primary treatment modality for breast cancer (BCa) patients. However, chemoresistance commonly arises in clinical settings, contributing to poor prognosis. The development of chemoresistance is a dynamic and complex process involving the activation of oncogenes and inactivation of tumor suppressor genes.

Nemo-like kinases (NLKs) integrate multiple signaling pathways and exhibit functional diversity in developmental processes, including the bone morphogenetic protein (BMP) pathway. However, their roles in insect wing development, particularly in hemimetabolous insects like the brown planthopper (Nilaparvata lugens), remain poorly understood. Here, we investigated the role of Nlnemo (Nlnmo), an NLK, in the wing development of N.

Background: The genomic landscape of esophageal squamous cell carcinoma (ESCC) has been characterized extensively, but there remains a significant need for actionable targets and effective therapies.

Methods: Here, we perform integrative analysis of genome-wide loss of heterozygosity and expression to identify potential tumor suppressor genes. The functions and mechanisms of one of the candidates, TACC2, are then explored both in vitro and in vivo, leading to the proposal of a therapeutic strategy based on the concept of synthetic lethality.
