Mutations in a gene for plastid ribosomal protein S6‐like protein reveal a novel developmental process required for the correct organization of lateral root meristem in ArabidopsisSummary Arabidopsis rfc3 mutants have previously been isolated with an altered fatty acid composition of membrane lipids. In this study, rfc3 was found to have a sucrose‐conditional defect in the patterning of distal elements in the lateral root meristem. By utilizing this feature, a sucrose‐sensitive process im... ...

Arbuscular mycorrhizal symbiosis is accompanied by local and systemic alterations in gene expression and an increase in disease resistance in the shootsSummary In natural ecosystems, the roots of many plants exist in association with arbuscular mycorrhizal (AM) fungi, and the resulting symbiosis has profound effects on the plant. The most frequently documented response is an increase in phosphorus nutrition; however, other effects have been noted, including increased resistance to abiotic and biotic stresses. Here ... ...

EZ‐Rhizo : integrated software for the fast and accurate measurement of root system architectureSummary The root system is essential for the growth and development of plants. In addition to anchoring the plant in the ground, it is the site of uptake of water and minerals from the soil. Plant root systems show an astonishing plasticity in their architecture, which allows for optimal exploitation of diverse soil structures and conditions. The signalling pathways... ...

Phân tích đồng thời các chất chuyển hóa trong củ khoai tây bằng phương pháp sắc ký khí – khối phổ Dịch bởi AI Tóm tắt Một phương pháp mới được trình bày, trong đó sắc ký khí kết hợp với khối phổ (GC–MS) cho phép phát hiện định lượng và định tính hơn 150 hợp chất trong củ khoai tây, với độ nhạy và tính đặc trưng cao. Trái ngược với các phương pháp khác được phát triển để phân tích chuyển hóa trong hệ thống thực vật, phương pháp này đại diện cho một cách tiếp cận không thiên ... ...

Molecular analysis of herbivore‐induced condensed tannin synthesis: cloning and expression of dihydroflavonol reductase from trembling aspen (Populus tremuloides)Summary In order to study condensed tannin synthesis and its induction by herbivory, a dihydroflavonol reductase (DFR) cDNA was isolated from trembling aspen (Populus tremuloides) . Bacterial overexpression demonstrated that this cDNA encodes a functional DFR enzyme, and Southern analysis revealed that DFR likely ... ...

ATHB4, a regulator of shade avoidance, modulates hormone response in Arabidopsis seedlingsSummary Plants sense the presence of competing neighboring vegetation as a change in light quality: i.e. they sense the reduced ratio of red light to far‐red light. The responses to shade are generally referred to as the shade avoidance syndrome (SAS), and involve various developmental changes intended to outgrow or outcompete the neighboring plants. Here, we analyz... ...

Plant stress granules and mRNA processing bodies are distinct from heat stress granulesSummary Similar to the situation in mammalian cells and yeast, messenger ribonucleo protein (mRNP) homeostasis in plant cells depends on rapid transitions between three functional states, i.e. translated mRNPs in polysomes, stored mRNPs and mRNPs under degradation. Studies in mammalian cells showed that whenever the dynamic exchange of the components between these s... ...

A nuclear‐encoded chloroplast‐targeted S1 RNA ‐binding domain protein affects chloroplast rRNA processing and is crucial for the normal growth of Arabidopsis thalianaSummary Despite the fact that a variety of nuclear‐encoded RNA ‐binding proteins (RBP s) are targeted to the chloroplast and play essential roles during post‐transcriptional RNA metabo... ...

The Arabidopsis ARGOS‐LIKE gene regulates cell expansion during organ growthSummary Cell expansion, and its coordination with cell division, plays a critical role in the growth and development of plant organs. However, the genes controlling cell expansion during organogenesis are largely unknown. Here, we demonstrate that a novel Arabidopsis gene, ARGOS‐LIKE (ARL ), which has some sequenc... ...

The transcription factor AtGRF5 and the transcription coactivator AN3 regulate cell proliferation in leaf primordia of Arabidopsis thalianaSummary The development of the flat morphology of leaf blades is dependent on the control of cell proliferation as well as cell expansion. Each process has a polarity with respect to the longitudinal and transverse axes of the leaf blade. However, only a few regulatory components of these processes have been identified to date. We have characterized two genes from <... ...
