Abstract Roots are essential for plant growth and development. Bamboo is a large Poaceae perennial with 1,642 species worldwide. However, little known about the transcriptional atlas that underpin root cell-type differentiation. Here, we set up modified protocol protoplast preparation reported single-cell transcriptomes of 14,279 filtered single cells derived from basal tips Moso bamboo. We ide...
trehalose is the alpha, alpha-1,1-linked glucose disaccharide. its metabolism is found in a wide variety of organisms and is seen as evolutionary old. trehalose metabolites are however present at only very low concentrations and their role in plants are not understood. the physiological effects of 100 mm trehalose on growth and carbon allocation in seedlings are characterized in this paper. tre...
استریکتوسیدین سینتاز یک آنزیم کلیدی مسییر بیوسنتز ایندول الکالوئیدهای مونوترپنی می باشد. آرابیدوپسیس قادر به تولید ترکیبات آلکالوئیدی نیست اما، ژن هایی مشابه استریکتوسیدین سینتاز در آن شناسایی شده است. ژن ssl6 از اعضاء خانواده ژنی شبه استریکتوسیدین سینتاز آرابیدوپسیس می باشد که در این تحقیق پاسخ ژن آن به تیمار شوری بصورت کمی بررسی و سپس در گیاه آرابیدوپسیس فرابیان شد. بمنظور تولید موتانت فرابیا...
Receptor-like kinases (RLKs) belong to the large RLK/Pelle gene family, and it is known that the Arabidopsis thaliana genome contains >600 such members, which play important roles in plant growth, development, and defense responses. Surprisingly, we found that rice (Oryza sativa) has nearly twice as many RLK/Pelle members as Arabidopsis does, and it is not simply a consequence of a larger predi...
Artemisinin, a potent antimalarial drug, is phytotoxic to many crops and weeds. The effects of artemisinin on stress markers, including fluorescence parameters, photosystem II photochemistry, photon energy dissipation, lipid peroxidation, reactive oxygen species generation and carbon isotope discrimination in Arabidopsis thaliana were studied. Arabidopsis ecotype Columbia (Col-0) seedlings were...
Mitochondrial carrier family proteins are diverse in their substrate specificity, organellar location, and gene expression. In Arabidopsis (Arabidopsis thaliana), 58 genes encode these six-transmembrane-domain proteins. We investigated the biological role of the basic amino acid carrier Basic Amino Acid Carrier2 (BAC2) from Arabidopsis that is structurally and functionally similar to ARG11, a y...
Although Arabidopsis is well established as the premiere model species in plant biology, rice (Oryza sativa) is moving up fast as the second-best model organism. In addition to the availability of large sets of genetic, molecular, and genomic resources, two features make rice attractive as a model species: it represents the taxonomically distinct monocots and is a crop species. Plant structural...
Four genes of the Arabidopsis (Arabidopsis thaliana) monosaccharide transporter-like superfamily share significant homology with transporter genes previously identified in the common ice plant (Mesembryanthemum crystallinum), a model system for studies on salt tolerance of higher plants. These ice plant transporters had been discussed as tonoplast proteins catalyzing the inositol-dependent effl...
Arabidopsis thaliana is one of the most intensively studied plant species. More recently, information is accumulating about its closest relatives, the former genus Cardaminopsis. A. thaliana diverged from these relatives, actually treated within three major lineages (Arabidopsis lyrata, Arabidopsis halleri, and Arabidopsis arenosa), approximately 5 mya. Significant karyotype evolution in A. tha...
Arabidopsis is a model system not only for studying numerous aspects of plant biology, but also for understanding mechanisms of the rapid evolutionary process associated with genome duplication and polyploidization. Although in animals interspecific hybrids are often sterile and aneuploids are related to disease syndromes, both Arabidopsis autopolyploids and allopolyploids occur in nature and c...
