Auto‐Downregulation of the Florigen FT Production Prevents Precocious Flowering in Plants
Advanced Science, EarlyView.This study shows that the leaf vein‐expressed FD complexes with the florigen FT to bind DNA motifs in FT promoter, which antagonizes CONSTANS‐mediated FT activation to feedback down‐regulate FT expression. This prevents an excessive induction of FT expression by inductive photoperiods, thereby precluding precocious transition to flowering in ...

The AGL6–ELF3–FT circuit controls flowering time in Arabidopsis
Plant Signaling & BehaviorAdjusting the timing of floral transition is essential for reproductive success in plants. A number of flowering regulators integrate internal and external signals to precisely determine the time to flower. We here report that the AGAMOUS-LIKE 6 (AGL6) –

microRNA production in Arabidopsis
Frontiers in Plant Science, 2023 In plants, microRNAs (miRNAs) associate with ARGONAUTE (AGO) proteins and act as sequence-specific repressors of target gene expression, at the post-transcriptional level through target transcript cleavage and/or translational inhibition. MiRNAs are mainly transcribed by DNA-dependent RNA polymerase II (POL II) and processed by DICER LIKE1 (DCL1 ...

Advanced Science, EarlyView.ARC3 levels are controlled by cytosolic and chloroplast proteolytic systems. PUB52 mediates ARC3 precursor ubiquitination and degradation in the cytosol, while CLPC1 promotes ARC3 degradation in chloroplasts, where ARC2 protects ARC3 from excessive breakdown. Disrupting these components causes chloroplast division defects, placing them upstream of ARC3.

Spatiotemporal expression patterns of cytosolic AtHSP90-2 in Arabidopsis seedlings
Plant Signaling & Behavior, 2023 Heat shock protein AtHSP90–2 is one of the three constitutive cytosolic HSP90s of Arabidopsis thaliana, which are highly homologous and show mild expression activation in response to stressful impacts.

Annotation of the Arabidopsis Genome [PDF]
Plant Physiology, 2003 The Arabidopsis Genome Sequencing Project was officially completed in late 2000, leading to the publication of a landmark paper describing, in broad outline, many salient features of the Arabidopsis genome ([Arabidopsis Genome Initiative [AGI], 2000][1]).

NLSS3 Impairs SHM1 Autophagic Degradation to Regulate Leaf Morphology and Salt Tolerance in Rice
Advanced Science, EarlyView.In rice, NLSS3 binds and shields SHM1 from autophagic degradation to maintain serine homeostasis. The A132P mutation in nlss3 disrupts this, triggering SHM1 loss, metabolic dysfunction, K+ imbalance, and impaired ROS scavenging, which collectively drive narrow leaves and salt sensitivity.

Overexpression of the
BMC Plant Biology, 2011 Background Brassinosteroids (BRs) are signaling molecules that play essential roles in the spatial regulation of plant growth and development. In contrast to other plant hormones BRs act locally, close to the sites of their synthesis, and thus ...
