Chromosomal Deletions Unlock Fusarium Wilt Resistance in Taiwan Bananas
Fusarium wilt has long threatened the global banana industry. Because most edible banana cultivars are sterile triploids, conventional breeding is difficult and often fails to deliver new cultivars acceptable to farmers and consumers. Throu...
Decoding Arabidopsis mRNA decay landscape shaped by XRN 5′-3′ exoribonucleases
Plant cells use a variety of exoribonucleases (XRNs) to remove mRNA processing remnants produced during mRNA maturation, or to clear damaged functional mRNA. Mining the substrates and products of XRNs can expand understanding of pre-mRNA pr...
Cultivar-specific markers, mutations, and chimerisim of Cavendish banana somaclonal variants resistant to Fusarium oxysporum f. sp. cubense tropical race 4
Fusarium oxysporum f. sp. cubense tropical race 4 (Foc TR4) is a destructive soil-borne fungus threatening global banana production. The effective control of Foc using fungicides is not available. The Taiwan Banana Research Institute develo...
Crime scene reconstruction: determining time of RNA death by analysis of RNA degradation fragments
In addition to regulating RNA synthesis, increasing or decreasing RNA degradation is an alternative way to control gene expression. Moreover, RNA degradation plays an important role in plant defense against pathogens by directly attacking p...
Widespread Exon Junction Complex Footprints in the RNA Degradome Mark mRNA Degradation before Steady State Translation
The RNA degradome is composed of assorted RNA degradation intermediates derived from diverse RNA degradation pathway. In 2016, we reported that the plant RNA degradome contains in vivo ribosome footprints. In this study, we further demonstr...
DCL2- and RDR6-dependent transitive silencing of SMXL4 and SMXL5 in Arabidopsis dcl4 mutants causes defective phloem transport and carbohydrate over-accumulation
Dicer-Like (DCL) enzymes are able to process double-stranded RNA into small RNAs. Arabidopsis DCL4 and DCL2 each allow the post-transcriptional gene silencing (PTGS) of viruses and transgenes, but DCL2 activity is mostly obscured by DCL4. T...
