Abstract The mechanisms controlling seed dormancy in Arabidopsis (Arabidopsis thaliana) have been characterized by proteomics using the dormant (D) accession Cvi originating from Cape Verde Islands. Comparative studies carried out with freshly harvested and after-ripened non-dormant (ND) seeds revealed a specific differential accumulation of 32 proteins. data suggested that proteins associated metabolic functions potentially involved germination can accumulate during after-ripening dry state...
The formation of abnormal amino acid residues is a major source spontaneous age-related protein damage in cells. l-isoaspartyl methyltransferase (PIMT) combats misfolding resulting from by catalyzing the conversion to their normal l-aspartyl forms. In this way, PIMT repair enzyme system contributes longevity and survival bacterial animal kingdoms. Despite discovery activity plants two decades ago, role during plant stress adaptation seed remains undefined. work, we have isolated Arabidopsis...
Small secreted peptides are important players in plant development and stress response. Using a targeted silico approach, we identified family of 14 Arabidopsis genes encoding precursors serine-rich endogenous (PROSCOOP). Transcriptomic analyses revealed that one member this family, PROSCOOP12, is involved processes linked to biotic oxidative as well root growth. Plants defective gene were less susceptible Erwinia amylovora infection showed an enhanced growth phenotype. In PROSCOOP12...
Shoot branching is a pivotal process during plant growth and development, antagonistically orchestrated by auxin sugars. In contrast to extensive investigations on hormonal regulatory networks, our current knowledge the role of sugar signalling pathways in bud outgrowth scarce. Based comprehensive stepwise strategy, we investigated glycolysis/the tricarboxylic acid (TCA) cycle oxidative pentose phosphate pathway (OPPP) control outgrowth. We demonstrated that these are necessary for promotion...
Despite having very similar initial pools of stored mRNAs and proteins in the dry state, mature Arabidopsis seeds can either proceed toward radicle protrusion or stay a dormant state upon imbibition. Dormancy breaking, prerequisite to germination completion, be induced by different treatments though underlying mechanisms remain elusive. Thus, we investigated consequence such on seed proteome. Two unrelated dormancy-releasing were applied seeds, namely, cold stratification exogenous nitrates,...
Abstract Small secreted peptides have been described as key contributors to complex signalling networks that control plant development and stress responses. The Brassicaceae-specific PROSCOOP family encodes precursors of Serine riCh endOgenOus Peptides (SCOOPs). In Arabidopsis SCOOP12 has shown promote the defence response against pathogens be involved in root development. Here, we explore its role a moderator primary We show PROSCOOP12 null mutation leads longer roots through differentiated...
ABSTRACT Alternaria brassicicola causes dark spot (or black spot) disease, which is one of the most common and destructive fungal diseases Brassicaceae spp. worldwide. Here, we report draft genome sequence strain Abra43. The assembly comprises 29 scaffolds, with an N 50 value 2.1 Mb. assembled was 31,036,461 bp in length, a G+C content 50.85%.
The shoot branching pattern is a determining phenotypic trait throughout plant development. During branching, BRANCHED1 (BRC1) plays master regulator role in bud outgrowth, and its transcript levels are regulated by various exogenous endogenous factors. RhBRC1 (the homologous gene of BRC1 Rosa hybrida) main whose posttranscriptional regulation response to sugar was investigated through 3′UTR. Transformed calluses containing construction composed the CaMV35S promoter, green fluorescent...
The transmission of seed-borne pathogens by the germinating seed is responsible for major crop diseases. immune responses facing biotic invaders are poorly documented so far.
Abstract A high throughput phenotyping tool for seed germination, the ScreenSeed technology, was developed with aim of screening genotype responsiveness and chemical drugs. This technology presently used Arabidopsis thaliana seeds to allow characterizing samples germination behavior by incubating in 96-well microplates under defined conditions detecting radicle protrusion through coat automated image analysis. study shows that this provides a fast procedure allowing handle thousands without...
Seeds play a vital role in the perpetuation of plant species, both natural environments and agriculture. However, they often face challenges from biotic stresses, such as seedborne pathogenic fungi. The transgenerational transmission these fungi, along with their dissemination during seed commercialization, can contribute to emergence global epidemic diseases, resulting substantial economic losses. One fungus is Alternaria brassicicola, responsible for causing black spot disease...
