The use of tools and methodologies for generating quality imagens is fundamental for studies in developmental biology. Obtaining imagens and quantifying with high sensitivity bioluminescence or fluorescence signals are important assets for studies in the field of plant and animal development. Therefore, the imaging system NEWTON 7.0 is ideal to achieve such goals. (AU)
Fundamental questions in plant biology include how cells and tissues maintain their identity over time and how they switch from one stable state to the next. Understanding such basic questions may help us to better predict how plants modulate their shoot architecture in response to endogenous cues and the environment. Shoot architecture is one of the main developmental factors affecting p…
Small RNAs or sRNAs (19-25 nt) regulate transcriptionally and posttranscriptionally gene expression in plants, modulating their transcriptome and proteome. Among these sRNAs, microRNAs (miRNAs) arise as key regulators of development. MiRNAs are generated from long single-strand RNA molecules (pri-miRNAs) that are processed by different enzymes to produce the mature miRNA. In plants, matur…
MicroRNAs (miRNAs) are important regulatory elements of gene expression. Similarly to codinggenes, miRNA genes follow a birth and death pattern of evolution likely reflecting functional relevance and divergence. For instance, miRNA529 is evolutionarily related to miRNA156 (a highly conserved miRNA in land plants), but it is lost in Arabidopsis thaliana. Interestingly, both miRNAs target s…

Post-embryonic hypocotyl growth is coordinated by the expansion of a few cells, which is modulated by hormones and responses to exogenous cues. The crosstalk between gibberellin (GA) and brassinosteroid (BR) is fundamental for hypocotyl growth and it has been proposed at the molecular level by the physical interaction between DELLA and BZR1. Although previous observation indicated that th…
Flowering is orchestrated by a complex network of internal factors (genetic and epigenetic), which are responsible for perceiving external signals (temperature and light) and determining the best time for plants to transition from vegetative to reproductive stage, thus guaranteeing their reproductive success. Several studies, using the Arabidopsis thaliana as plant model, characterized th…

The development of lateral branches is essential for determining the shoot architecture and it strongly correlates with crop yield. This process is divided in two steps: the initiation of axillary meristems (AMs) and axillary buds; subsequent axillary bud dormancy or outgrowth. Transcription factors from the Squamosa Promoter Protein Binding Protein (SPL/SBP) family are targeted by microR…

Distinct environments and latitudes limited human agricultural activities due to the photoperiodic response and its strong impact on flowering time and yield of crops. The CONSTANS (CO) gene is the central regulatory hub in the photoperiodic pathway his several species. In Arabidopsis, CO was identified as a transcriptional activator of the flowering-associated phloem-mobile protein named…
The light perception in seedlings modulates the post-embryonic development, integrating phytohormone and other endogenous responses with environmental cues. A proper hypocotyl elongation at the first hours/days of development is critical for plant establishment and photosynthetic success. The precise coordination of hypocotyl elongation is under parallel and redundant regulatory pathways.…
Driving energy from ATP hydrolysis, chromatin may be more accessible to transcription factors. Such chromatin remodeling is achieved by SWI2/SNF2 complex, with a core ATPase BRAHMA (BRM), SPLAYED (SYD) or MINUSCULE (MINU) in terrestrial plants. BRM is the most widely studied in plants, using knock-down mutants in Arabidopsis thaliana to elucidate its function. On the other hand, MINU is u…
