Nested PCR to optimize rpoB metabarcoding for low-concentration and host-associated bacterial DNA

Laëtitia Leclerc, Gabryelle Agoutin, Thierry Brévault, Antony Champion et autres

ABSTRACT Housekeeping genes have proven to be effective taxonomic markers for characterizing bacterial microbiota in short-read amplicon metabarcoding studies. A region of the rpoB gene has been shown to minimize Operational Taxonomic Unit (OTU) overestimation bias with a high degree of accuracy, …

Rice JASMONIC ACID OXIDASES control resting jasmonate metabolism to promote growth and repress basal immune responses

Simon Y. A. Ndecky, Ludivine Malherbe, Claire Villette, Véronique Chalvon et autres

Catabolic conversions within the jasmonate pathway have substantial consequences on phytohormone signaling output. In dicots, the jasmonic acid oxidase (JAO) catabolic route leads to jasmonic acid (JA) hydroxylation, which limits its conjugation into bioactive jasmonoyl-isoleucine (JA-Ile). Here, we functionally characterized the JAO …

Abstract Background Housekeeping genes have proved effective taxonomic markers for characterizing bacterial microbiota in short-read amplicon metabarcoding studies. A region of the rpoB gene, in particular, has been shown to minimize OTU overestimation bias with a high degree of accuracy, providing better …

Two Lateral Organ Boundary Domain Transcription Factors HvCRL1 and HvCRL1L1 Regulate Shoot-Borne Root Formation in Barley (Hordeum vulgare L.)

Thu D. Nguyen, Mathieu Gonin, Michal Motyka, Antony Champion et autres

Abstract Plant-specific LOB-domain (LBD) transcription factors are crucial in post-embryonic root initiation. In cereals, the fibrous root system comprises primary and seminal roots that develop during embryogenesis and lateral- and crown roots that develop post-embryonically from root or stem, respectively. In rice, …

Transcriptomic and metabolomic reveal OsCOI2 as the jasmonate-receptor master switch in rice root

Mohamad Cheaib, Tràng Hiếu Nguyen, Marie Couderc, Julien Serret et autres

Jasmonate is an essential phytohormone involved in plant development and stress responses. Its perception occurs through the CORONATINE INSENSITIVE (COI) nuclear receptor allowing to target the Jasmonate-ZIM domain (JAZ) repressors for degradation by the 26S proteasome. Consequently, repressed transcription factors are released …

Nitrate and ammonium, the yin and yang of nitrogen uptake: a time-course transcriptomic study in rice

Pierre‐Mathieu Pélissier, Boris Parizot, Letian Jia, Alexa De Knijf et autres

Nitrogen is an essential nutrient for plants and a major determinant of plant growth and crop yield. Plants acquire nitrogen mainly in the form of nitrate and ammonium. Both nitrogen sources affect plant responses and signaling pathways in a different way, but …

Rice JASMONIC ACID OXIDASES (OsJAO) control resting jasmonate metabolism to promote development and repress basal immune responses

Simon Y. A. Ndecky, Ludivine Malherbe, Claire Villette, Véronique Chalvon et autres

Abstract Recent research has established that catabolic conversions within the jasmonate pathway have significant consequences on hormone signaling output. In dicotyledonous plants, the jasmonic acid oxidase (JAO) catabolic route is endowed with a regulatory function by diverting jasmonic acid (JA) towards hydroxylation, …

Early transcriptomic responses of rice leaves to herbivory by Spodoptera frugiperda

Laëtitia Leclerc, Tràng Hiếu Nguyen, Pénélope Duval, Victoria Mariotti et autres

During herbivory, chewing insects deposit complex oral secretions (OS) onto the plant wound. Understanding how plants respond to the different cues of herbivory remains an active area of research. In this study, we used an herbivory-mimick experiment to investigate the early transcriptional …

Author Response: Glutaredoxin regulation of primary root growth is associated with early drought stress tolerance in pearl millet

Carla de la Fuente Cantó, Alexandre Grondin, Bassirou Sine, Marilyne Debieu et autres

Increased primary root growth in pearl millet is correlated with early water stress tolerance, an important constraint in agrosystems in the Sahel, and is associated with the regulation of root cell elongation by a glutaredoxin.
