Many stimuli such as hormones and stress factors elicit changes in intracellular calcium content that serve to convey information and activate appropriate responses. 1 These Ca 2+ signals are perceived by different Ca 2+ sensors, and calmodulin (CaM) is one of the best characterized Ca 2+ sensors in eukaryotes. Calmodulinlike (CML) proteins extend the Ca 2+ -toolkit in plants; CMLs share sequence similarity with the ubiquitous and highly conserved CaM, however, except for some of them, their roles at physiological and molecular levels remain largely unknown. 2,3In our group, we reported data on Arabidopsis thaliana CML9 that exhibits 46% amino acid sequence identity with CaM. 4,5 We showed that CML9 transcripts are found in all organs and that CML9 gene is rapidly induced by both abiotic and biotic stress. In a recent publication in Plant Journal, we demonstrated that CML9 expression is also rapidly induced by the phytopathogenic bacteria Pseudomonas syringae pv tomato DC3000 (Pst DC3000) 4 and that this upregulation belongs to salicylic acid (SA) production and to the flagellin perception receptor FLS2. Moreover, exogenous applications of SA or flg22, the biological active peptide of flagellin, are also able to induce rapid and transient CML9 gene expression and using a reverse genetic approach, we established that CML9 participates in plant innate immunity through a flagellin-dependent signaling pathway. 4 In addition to mediate plant innate immunity, flagellin and flg22 are also known to inhibit root elongation and seedling growth.6 Thus, we explored this facet of flagellin effect and we bring here new informations on plant growth behavior of CML9 overexpressing and knockout lines upon flg22 treatments and Plants have evolved complex signaling networks to respond to their fluctuating environment and adapt their growth and development. Calcium-dependent signaling pathways play key role in the onset of these adaptive responses. in plant cells, the intracellular calcium transients are triggered by numerous stimuli and it is supposed that the large repertory of calcium sensors present in higher plants could contribute to integrate these signals in physiological responses. here, we present data on CmL9, a calmodulin-like protein that appears to be involved in plant responses to both biotic and abiotic stress. using a reverse genetic approach based on gain and loss of function mutants, we present here data indicating that this CmL might also be involved in root growth control in response to the flagellin, a pathogen-associated molecular pattern (PamP) also involved in plant immunity. Keywords: Calmodulin-like protein, Arabidopsis thaliana, root growth, flagellin, gibberellins discuss the possible involvement of CML9 in plant growth control through hormonal compounds.

“…A calmodulin-like protein (probable CML48, predgene 022002) was also detected in the neighborhood of a microgeographic outlier. Calmodulin and calmodulin-like plant calcium sensors have evolved unique functions of high importance in the regulation of plant development and plant response to stress (Perochon et al 2011). We also detected a probable cellulose synthase A (predgene 000745) whose mutations can alter morphology or induce resistance to cellulose biosynthesis inhibitors as reported in A. thaliana (Richmond 2000), a gene for plant metal tolerance (predgene 014347), and a mRNA-decapping enzymelike (predgene 011170) which is of importance for early seedling development (Goeres et al…”

Plant populations are able to undergo very localized adaptive processes, that allow continuous populations to adapt to divergent habitats in spite of recurrent gene flow. Here, we carried out a genome scan for selection through whole-genome sequencing of pools of populations, sampled according to a nested sampling design, to evaluate microgeographic adaptation in the hyperdominant Amazonian tree Eperua falcata Aubl. (Fabaceae). A high-coverage genomic resource of ~250 Mb was assembled de novo and annotated, leading to 32 789 predicted genes. 97 062 bi-allelic SNPs were detected in 25 803 contigs were detected, and a custom Bayesian model we implemented to uncover candidate genomic targets of divergent selection.A set of 290 'divergence' outlier SNPs was detected at the regional scale (between study sites), while 185 SNPs located in the vicinity of 106 protein-coding genes were detected as replicated outliers between microhabitats within regions. These genes possibly underlie ecologically important phenotypes and tend to indicate that adaptation to microgeographic habitat patchiness would affect genomic regions involved in a variety of physiological processes, among which plant response to stress (for e.g., oxidative stress, hypoxia and metal toxicity) and biotic interactions. Identification of genomic targets of microgeographic adaptation in the Neotropics supports the hypothesis -frequently raised at the community level -that local adaptation would be a key driver of ecological diversification, probably operating across multiple spatial scales, from large-(i.e. regional) to microgeographic-(i.e. landscape) scales.

“…A partir da detecção desse estímulo por parte da planta, é desencadeada a síntese de calmodulinas, compostos que atuam na regulagem de proteínas e de fito-hormônios, que ativam grupos de enzimas que induzem uma resposta por parte da planta, como a produção de metabólitos secundários, aumento da biossíntese de lignina e outras estratégias de defesas (PEROCHON et al, 2011 …”

RESUMO -O mogno-brasileiro possui alto valor madeireiro, mas seu cultivo comercial é inviabilizado pelo ataque da broca Hypsipyla grandella. Objetivou-se avaliar o efeito de doses de cálcio e boro nas variáveis de crescimento do mogno e na resistência ao ataque da broca H. grandella . O delineamento utilizado foi o fatorial 4 2 em blocos ao acaso com quatro doses de cálcio (0, 100, 200 e 400 mg L -1 ) e quatro de boro (0; 0,5; 2; e 4 mg L -1 ) e três repetições com três plantas por repetição. Avaliaram-se: altura, diâmetro, massa seca aérea e de raiz, relação parte aérea:raiz, taxa de infestação e comprimento da galeria construída pela broca. Os dados foram submetidos ao teste de Tukey a 5% e à análise de correlação e regressão. Não houve interação estatística entre os nutrientes, nem significância de altura e diâmetro do coleto. A massa de raízes e da parte aérea apresentou os maiores resultados na omissão dos elementos, verificando as menores relações parte aérea:raiz nas doses de 100 mg L
