What specific genes are involved in the dwarfing of plants?
Best insight from top research papers
The dwarfing of plants involves specific genes such as CpGA2ox and CpGAI in Chimonanthus praecox , CmoCh08G006170 in pumpkin , Rc5NG4-1 in castor bean , and genes related to plant hormone pathways in tetraploid poplar . These genes play crucial roles in regulating plant height by affecting hormone levels, cell growth, and development. For instance, CpGA2ox and CpGAI influence gibberellic acid (GA) synthesis and signaling pathways in wintersweet, while CmoCh08G006170 is involved in gibberellin biosynthesis in pumpkin. Rc5NG4-1 in castor bean affects IAA uptake capacities, and genes related to plant hormone pathways in tetraploid poplar impact the balance of various hormones like IAA, GA, ABA, and JA, leading to dwarfing. Understanding the functions of these genes provides insights into the molecular mechanisms underlying plant dwarfism and offers opportunities for genetic breeding to develop dwarf varieties in economically important plants.

What are the different genes that can be expressed in plants?5 answersVarious genes can be expressed in plants for different purposes. Plant expression vectors like MIDAS‐P allow for the simultaneous expression of multiple genes, such as anti-HIV proteins and reporter genes. Inducible gene expression systems, including tetracycline, steroid, ethanol, insecticide, and copper-induced systems, provide spatiotemporal and quantitative control over gene expression. Reference genes are crucial for gene expression analyses in plants, with over 120 genes used for normalization in various plant species under different conditions. Plant intracellular Ras-group related leucine-rich repeat (LRR) proteins play essential roles in developmental pathways, with distinct tissue-specific expression patterns identified in Arabidopsis thaliana. Different methodologies like cDNA libraries, microarrays, and RNA sequencing are used to study gene expression in plants, aiding in the identification and characterization of genes involved in cellular processes.
What are the genetic pathways involved in the regulation of flowering time in plants?4 answersFlowering time in plants is regulated by multiple genetic pathways. The major pathways include the photoperiod, vernalization, autonomous, gibberellin, age, thermosensory, sugar, stress, and hormonal pathways. The photoperiod pathway is the most important and is regulated by day length, which acts as an external cue for flowering time determination. The vernalization pathway involves the regulation of flowering by prolonged exposure to cold temperatures. The autonomous pathway controls flowering independently of environmental cues. The gibberellin pathway is involved in promoting flowering. Hormonal control of flowering, although not considered a major pathway, has been shown to play a role in mediating various stress signals. Understanding the molecular regulation of these pathways is important for crop improvement and adaptation to local environments.
What are some genes involved in seed development?4 answersSeed development involves the regulation of various genes. SEEDSTICK (STK), GORDITA (GOA), and AUXIN RESPONSE FACTOR 2 (ARF2) are transcription factors that play a role in seed development in Arabidopsis thaliana. The BASIC PENTACYSTEINE (BPC) gene CjBPC1 is involved in the formation of double-flower due and affects genes involved in ovule and seed development, such as SEEDSTICK, LEAFY COTYLEDON2, ABSCISIC ACID INSENSITIVE 3, and FUSCA3. The hydroxylase gene FAH12 is responsible for the hydroxylation of fatty acids during seed development in Paysonia auriculata. The molecular networks of genes and signaling of gibberellin (GA) and abscisic acid (ABA) are involved in the regulation of seed development from embryogenesis to maturation. In alfalfa, genes related to ABA and GA pathways are important for seed development and could be potential targets for improving alfalfa seed yield.
What are the different types of small G proteins in plants?5 answersHeterotrimeric G proteins in plants consist of Gα, Gβ, and Gγ subunits. There are two types of Gα subunits in plants: canonical Gα subunits similar to those found in animals and extra-large Gα (XLGα) subunits with extended N-terminal domains. Both types of Gα subunits interact with Gβγ dimers and regulator of G protein signaling (RGS) proteins. The distribution and evolutionary history of G proteins in plants show that a minimal set of XLGαβγ trimers exists in all land plants, but their presence is sporadic in algae. Individual G protein components have distinct evolutionary histories, with XLGα exhibiting lineage-specific gene duplications and Gα and RGS showing instances of gene loss. Gγ subunits diverged before the emergence of land plants and have three distinct subtypes.
What re small non coding rnas in plants?3 answersSmall non-coding RNAs (sRNAs) in plants are short RNA molecules that do not code for proteins but play a regulatory role in gene expression. They are classified into different classes, including microRNAs (miRNAs), short interfering RNAs (siRNAs), and transacting siRNAs (tasiRNAs). These sRNAs are typically 20-30 nucleotides in length and are involved in various biological processes, such as plant development, response to biotic and abiotic stresses, and plant-pathogen interactions. They can regulate gene expression by binding to complementary sites in transcripts, preventing their translation into proteins. Additionally, sRNAs can be transported between cells and even between different species, modulating important interactions between plants and other organisms. The intercellular transmission of sRNAs is believed to occur through extracellular vesicles or other nonvesicular vehicles, triggering trans-kingdom RNA interference in recipient cells.
What are the roles of auxins in plant growth?4 answersAuxins play a fundamental role in plant growth and development. They regulate various physiological processes, including cell division, differentiation, and root architecture modification. Auxins act as signaling molecules to regulate gene expression and control numerous developmental processes throughout all stages of plant growth. They influence gene expression regulation by connecting synthesis and distribution, and they interact with specific transcription factors and proteins to modulate environmental responses. The biosynthesis of auxins involves both tryptophan-dependent and tryptophan-independent pathways, with several intermediate compounds and key enzymes involved. Auxins also have growth-promoting properties and are involved in plant plasticity to environmental fluctuations. Overall, auxins play a crucial role in regulating plant growth, development, and response to environmental stimuli.
