Variation burst during dedifferentiation and increased CHH-type DNA methylation after 30 years of in vitro culture of sweet orange.

Somaclonal variation arising from tissue culture may provide a valuable resource for the selection of new germplasm, but may not preserve true-to-type characteristics, which is a major concern for germplasm conservation or genome editing. The genomic changes associated with dedifferentiation and somaclonal variation during long-term in vitro culture are largely unknown. Sweet orange was one of the earliest plant species to be cultured in vitro and induced via somatic embryogenesis.

Rubidium Ions Enhanced Crystallinity for Ruddlesden-Popper Perovskites.

Tailoring the organic spacing cations enables developing new Ruddlesden-Popper (RP) perovskites with tunable optoelectronic properties and superior stabilities. However, the formation of highly crystallized RP perovskites can be hindered when the structure of organic cations become complex. Strategies to regulate crystal growing process and grains quality remain to be explored.

Evolutionary dynamics of lincRNA transcription in nine citrus species.

Long intergenic non-coding RNAs (lincRNAs) play important roles in various biological processes in plants. However, little information is known about the evolutionary characteristics of lincRNAs among closely related plant species. Here, we present a large-scale comparative study of lincRNA transcription patterns in nine citrus species.

miR3954 is a trigger of phasiRNAs that affects flowering time in citrus.

In plant, a few 22-nt miRNAs direct cleavages of their targets and trigger the biogenesis of phased small interfering RNAs (phasiRNAs) in plant. In this study, we characterized a miRNA triggering phasiRNAs generation, miR3954, and explored its downstream target genes and potential function. Our results demonstrated that miR3954 showed specific expression in the flowers of citrus species, and it targeted a NAC transcription factor (Cs7 g22460) and two non-coding RNA transcripts (lncRNAs, Cs1 g09600 and Cs1 g09635).
