  • A dual function of SnRK2 kinases in the regulation of SnRK1 and plant growth
    Nat. Plants (IF 13.256) Pub Date : 2020-10-19
    Borja Belda-Palazón; Mattia Adamo; Concetta Valerio; Liliana J. Ferreira; Ana Confraria; Diana Reis-Barata; Américo Rodrigues; Christian Meyer; Pedro L. Rodriguez; Elena Baena-González

    Adverse environmental conditions trigger responses in plants that promote stress tolerance and survival at the expense of growth1. However, little is known of how stress signalling pathways interact with each other and with growth regulatory components to balance growth and stress responses. Here, we show that plant growth is largely regulated by the interplay between the evolutionarily conserved energy-sensing

    Given the 2,400-fold range of genome sizes (0.06–148.9 Gbp (gigabase pair)) of seed plants (angiosperms and gymnosperms) with a broadly similar gene content (amounting to approximately 0.03 Gbp), the repeat-sequence content of the genome might be expected to increase with genome size, resulting in the largest genomes consisting almost entirely of repetitive sequences. Here we test this prediction,

    Sustainable Development Goal (SDG) 2 consists of five targets ranging from the eradication of hunger and malnutrition to doubling productivity of small-scale farmers and ensuring sustainable and resilient food production systems. Trade-offs and synergies arise between strategies to achieve any one of these targets, which complicates the use of evidence to guide policies and investments since most analyses

    Polar growth requires the precise tuning of Rho GTPase signalling at distinct plasma membrane domains. The activity of Rho of plant (ROP) GTPases is regulated by the opposing action of guanine nucleotide-exchange factors (GEFs) and GTPase-activating proteins (GAPs).

    Assessing cell proliferation dynamics is crucial to understand the spatiotemporal control of organogenesis. Here we have generated a versatile fluorescent sensor, PlaCCI (plant cell cycle indicator) on the basis of the expression of CDT1a-CFP, H3.1-mCherry and CYCB1;1-YFP, that identifies cell cycle phases in Arabidopsis thaliana.

    MicroRNAs (miRNAs) are processed products of primary miRNAs (pri-miRNAs) and regulate the target gene expression. Though the regulatory roles of the several mature plant miRNAs have been studied in detail, the functions of other regions of the pri-miRNAs are still unrecognized.

    Some plants can ‘remember’ past environmental experience to become adapted to a given environment.

    Ribulose-1,5-bisphosphate carboxylase–oxygenase (Rubisco) catalyses the first step in carbon fixation and is a strategic target for improving photosynthetic efficiency.

    The unparalleled performance of Chlorella ohadii under irradiances of twice full sunlight underlines the gaps in our understanding of how the photosynthetic machinery operates, and what sets its upper functional limit. Rather than succumbing to photodamage under extreme irradiance, unique features of photosystem II function allow C. ohadii to maintain high rates of photosynthesis and growth, accompanied

  • Sp(l)icing up PepR signalling.
    Nat. Plants (IF 13.256) Pub Date : 2020-07-20
    Lennart Wirthmueller,Tina Romeis

    Alternative splicing provides a fundamental and ubiquitous mechanism of gene regulation. Stimuli-induced retention of introns introduces novel proteoforms with altered signalling output: full-length CPK28 blocks immune signalling, while a truncated variant, lacking calcium responsiveness, promotes it.

  • Dynamic regulation of Pep-induced immunity through post-translational control of defence transcript splicing.

    The survival of all living organisms requires the ability to detect attacks and swiftly counter them with protective immune responses. Despite considerable mechanistic advances, the interconnectivity of signalling modules often remains unclear. A newly characterized protein, IMMUNOREGULATORY RNA-BINDING PROTEIN (IRR), negatively regulates immune responses in both maize and Arabidopsis, with disrupted

  • Plant pan-genomes are the new reference.
    Nat. Plants (IF 13.256) Pub Date : 2020-07-20
    Philipp E Bayer,Agnieszka A Golicz,Armin Scheben,Jacqueline Batley,David Edwards

    Recent years have seen a surge in plant genome sequencing projects and the comparison of multiple related individuals. The high degree of genomic variation observed led to the realization that single reference genomes do not represent the diversity within a species, and led to the expansion of the pan-genome concept. Pan-genomes represent the genomic diversity of a species and includes core genes,

  • Degradation of SERRATE via ubiquitin-independent 20S proteasome to survey RNA metabolism.
    Nat. Plants (IF 13.256) Pub Date : 2020-07-20
    Yanjun Li,Di Sun,Zeyang Ma,Karissa Yamaguchi,Lin Wang,Songxiao Zhong,Xingxing Yan,Baoshuan Shang,Yukihiro Nagashima,Hisashi Koiwa,Jiajia Han,Qi Xie,Mingguo Zhou,Zhiye Wang,Xiuren Zhang

    SERRATE (SE) is a key factor in RNA metabolism. Here, we report that SE binds 20S core proteasome α subunit G1 (PAG1) among other components and is accumulated in their mutants. Purified PAG1-containing 20S proteasome degrades recombinant SE via an ATP- and ubiquitin-independent manner in vitro. Nevertheless, PAG1 is a positive regulator for SE in vivo, as pag1 shows comparable molecular and/or developmental

  • Linking key steps of microRNA biogenesis by TREX-2 and the nuclear pore complex in Arabidopsis.
    Nat. Plants (IF 13.256) Pub Date : 2020-07-20
    Bailong Zhang,Chenjiang You,Yong Zhang,Liping Zeng,Jun Hu,Minglei Zhao,Xuemei Chen

    Unlike in metazoans, the stepwise biogenesis of microRNAs (miRNAs) in plants occurs within the nucleus. Whether or how the major steps in miRNA biogenesis are coordinated is largely unknown. Here we show that the plant TREX-2 complex promotes multiple steps in miRNA biogenesis, including transcription, processing and nuclear export. THP1 and SAC3A—the core subunits of TREX-2—interact and colocalize
