In the version of this Article originally published, the authors incorrectly referred to the fluorescent protein Venus being used in their study; the actual one used was enhanced yellow fluorescence protein (eYFP).

Retrotransposons have played an important role in the evolution of host genomes1,2 . Their impact is mainly deduced from the composition of DNA sequences that have been fixed over evolutionary time2 . Such studies provide important 'snapshots' reflecting the historical activities of transposons but do not predict current transposition potential. We previously reported sequence-independent retrotransposon trapping (SIRT) as a method that, by identification of extrachromosomal linear DNA (eclDNA), revealed the presence of active long terminal repeat (LTR) retrotransposons in Arabidopsis3 ...

Streptococcus pyogenes Cas9 (SpCas9) is widely used for genome editing and requires NGG as a protospacer adjacent motif (PAM). Here, we show that the engineered SpCas9 (SpCas9-NGv1) can efficiently mutagenize endogenous target sites with NG PAMs in the rice and Arabidopsis genomes. Furthermore, we demonstrate that the SpCas9-NGv1 nickase fused to cytidine deaminase mediates C-to-T substitutions near the 5' end of the target sequence.

Vernalisation is the programmed physiological process in which prolonged cold-exposure provides competency to flower in plants; widely found in winter and biennial species, such as Arabidopsis, fruit trees, vegetables and wheat. This phenomenon is regulated by diverse genetic networks, and memory of vernalisation in a life cycle mainly depends on epigenetic mechanisms. However, less is known about how to count winter-dosage for flowering in plants. Here, we compare the vernalisation genetic framework between the dicots Arabidopsis, temperate grasses, wheat, barley and Brachypodium...

Improved plant varieties are important in our attempts to face the challenges of a growing human population and limited planet resources. Plant breeding relies on meiotic crossovers to combine favourable alleles into elite varieties1 . However, meiotic crossovers are relatively rare, typically one to three per chromosome2 , limiting the efficiency of the breeding process and related activities such as genetic mapping. Several genes that limit meiotic recombination were identified in the model species Arabidopsis thaliana2 ...

A major problem facing humanity is that our numbers are growing but the availability of land and fresh water for agriculture is not. This problem is being exacerbated by climate change-induced increases in drought, and other abiotic stresses. Stress-resistant crops are needed to ensure yield stability under stress conditions and to minimize the environmental impacts of crop production. Evolution has created thousands of species of naturally stress-resistant plants (NSRPs), some of which have already been subjected to human domestication and are considered minor crops...

The turnover of cytoplasmic material by autophagic encapsulation and delivery to vacuoles is essential for recycling cellular constituents, especially under nutrient-limiting conditions. To determine how cells/tissues rely on autophagy, we applied in-depth multi-omic analyses to study maize (Zea mays) autophagy mutants grown under nitrogen-replete and -starvation conditions. Broad alterations in the leaf metabolome were evident in plants missing the core autophagy component ATG12, even in the absence of stress, particularly affecting products of lipid turnover and secondary metabolites, which were underpinned by substantial changes in the transcriptome and/or proteome...

In the version of this Article originally published, the name of author Zhenpeng Luo was incorrectly listed as Zhenpeng Luo Luo. Additionally, nitrate in Fig. 6b was incorrectly shown as 'NO3 + ' rather than 'NO3 - '. This has now been amended.

The phytohormone cytokinin regulates diverse aspects of plant growth and development, probably through context-dependent transcriptional regulation that relies on a dynamic interplay between regulatory proteins and chromatin. We employed the assay for transposase accessible chromatin with sequencing to profile changes in the chromatin landscape of Arabidopsis roots and shoots in response to cytokinin. Our results reveal differentially accessible chromatin regions indicative of dynamic regulation in response to cytokinin...

Mitochondria and chloroplasts (plastids) both harbour extranuclear DNA that originates from the ancestral endosymbiotic bacteria. These organelle DNAs (orgDNAs) encode limited genetic information but are highly abundant, with multiple copies in vegetative tissues, such as mature leaves. Abundant orgDNA constitutes a substantial pool of organic phosphate along with RNA in chloroplasts, which could potentially contribute to phosphate recycling when it is degraded and relocated. However, whether orgDNA is degraded nucleolytically in leaves remains unclear...

Advances in deciphering the functional architecture of eukaryotic genomes have been facilitated by recent breakthroughs in sequencing technologies, enabling a more comprehensive representation of genes and repeat elements in genome sequence assemblies, as well as more sensitive and tissue-specific analyses of gene expression. Here we show that PacBio sequencing has led to a substantially improved genome assembly of Medicago truncatula A17, a legume model species notable for endosymbiosis studies1 , and has enabled the identification of genome rearrangements between genotypes at a near-base-pair resolution...

In the version of this Article originally published, an incorrect immunoblot was used in the left, middle panel of Fig. 6a, which describes α-tubulin expression in whole-cell extracts. This panel, and the corresponding quantitative result shown in Supplementary Fig. 11e, have now been corrected in the Article. This does not affect the results or conclusions of this work.

RNA polymerase II (Pol II) plays an essential role in gene expression. We used plant native elongating transcript sequencing and global run-on sequencing to profile nascent RNAs genome wide in Arabidopsis. We found that Pol II tends to accumulate downstream of the transcription start site (TSS). Moreover, Pol II with an unphosphorylated carboxyl-terminal domain (CTD) mainly accumulates downstream of the TSS, while Pol II with a Ser 5P CTD associates with spliceosomes, and Pol II with a Ser 2P CTD presents a sharp peak within 250 base pairs downstream of the polyadenylation site (PAS)...

The frequency and orientation of cell division are regulated by intercellular signalling molecules; however, tissue-specific regulatory systems for cell divisions are only partially understood. Here, we report that the peptide hormone CLAVATA3/ESR-RELATED 9/10 (CLE9/10) regulates two different developmental processes, stomatal lineage development and xylem development, through two distinct receptor systems in Arabidopsis thaliana. We show that the receptor kinase HAESA-LIKE 1 (HSL1) is a CLE9/10 receptor that regulates stomatal lineage cell division, and BARELY NO MERISTEM (BAM) class receptor kinases are CLE9/10 receptors that regulate periclinal cell division of xylem precursor cells...
