In Arabidopsis, the gene CONSTANS responds to long day conditions and enables flowering when it stops repressing flowering locus t. [13] In rice, photoperiodic response is slightly more complex and is controlled by the florigen genes Rice Flowering locus T 1 (RFT1) and Heading date 3 a (Hd3a). Hd3a, is a homolog of flowering locus t and, when ...
[1] [5]: 488 In Arabidopsis, the FLOWERING LOCUS T (FT) genes encode for the flowering hormone and in rice the hormone is encoded by Hd3a genes thereby making these genes orthologs. [1] It was found though the use of transgenic plants that the Hd3a promoter in rice is located in the phloem of the leaf along with the Hd3a mRNA.
ABC model of flower development guided by three groups of homeotic genes.. The ABC model of flower development is a scientific model of the process by which flowering plants produce a pattern of gene expression in meristems that leads to the appearance of an organ oriented towards sexual reproduction, a flower.
Four novel alternative genetic codes were discovered in bacterial genomes by Shulgina and Eddy using their codon assignment software Codetta, and validated by analysis of tRNA anticodons and identity elements; [3] these codes are not currently adopted at NCBI, but are numbered here 34-37, and specified in the table below.
The new Glossaries are built on a vibrant FLASH-based web design employing colorful pages, clear digital audio files, color illustrations, 3-D animations, a "Test Your Gene IQ" function, real-time applets to "cite a term in a paper", "suggest a term", and "share a term" via email. The list of terms was expanded to 256 entries.
This tool identifies all open reading frames using the standard or alternative genetic codes. The deduced amino acid sequence can be saved in various formats and searched against the sequence database using the basic local alignment search tool (BLAST) server. The ORF Finder should be helpful in preparing complete and accurate sequence submissions.
This is the standard or universal genetic code. This table is found in both DNA Codon Table and Genetic Code (And probably a few other places), so I'm pulling it out so it can be common. By default it's the DNA code (using the letter T for Thymine ); use template parameter "T=U" to make it the RNA code (using U for Uracil ).
One is a plant gene called the resistance gene. The other is a parasite gene called the avirulence (Avr) gene. Plants producing a specific R gene product are resistant towards a pathogen that produces the corresponding Avr gene product. [5] Gene-for-gene relationships are a widespread and very important aspect of plant disease resistance.
