Which fruit has more genes than humans?
Tomato
More Genes Than Humans: The Tomato Decoded. The tomato, whose genome has just now been decoded, turns out to be one well-endowed vegetable, possessing 31,760 genes.
Why do humans have fewer genes?
In the past few years, it has become clear that a phenomenon called alternative splicing is one reason human genomes can produce such complexity with so few genes. In some genes, different combinations of exons can become active at different times, and each combination yields a different protein.
Do onions have more genes than humans?
Since the onion (Allium cepa) is a diploid organism having a haploid genome size of 15.9 Gb, it has 4.9x as much DNA as does a human genome (3.2 Gb).
Do all tomatoes have genes?
Scientists have described the genetic underpinnings of 100 different types of tomatoes. A new analysis of genetic variation in tomatoes has uncovered more than 230,000 previously hidden, large-scale differences in DNA among varieties. As tomato plants evolved, segments of DNA were deleted, duplicated or rearranged.
Do tomatoes have more genes?
Plant geneticists from 14 different countries spent the last nine years mapping the genetic makeup of the tomato, and have discovered that the tomato contains 31,760 genes – that’s 7,000 more genes than a human being! The tomato’s genome is actually closer to that of a potato.
What genes are in tomatoes?
Table 1
| Gene symbol | Locus | Defined function/associated fruit phenotype (+ or −)a |
|---|---|---|
| SlIAA9 | Solyc04g076850 | Auxin signaling/parthenocarpy (−) |
| SlARF7 | Solyc07g042260 | Auxin signaling/parthenocarpy (−) |
| SlTIR1 | Solyc09g074520 | Auxin signaling/parthenocarpy (+) |
| AUCSIA1 | Solyc10g054660 | Auxin signaling/parthenocarpy (−) |
Do apples have more genes than humans?
The apple genome has approximately 57,000 genes, which was the highest number of any plant genome studied at the time, and more genes than the human genome which has about 25,000 genes.
How many genes does a tomato have?
The Tomato Has More Genes Than Humans. Plant geneticists from 14 different countries spent the last nine years mapping the genetic makeup of the tomato, and have discovered that the tomato contains 31,760 genes – that’s 7,000 more genes than a human being! The tomato’s genome is actually closer to that of a potato.
Can we decode the tomato genome to breed better Tomatoes?
A consortium of plant geneticists from 14 countries has spent nine years decoding the tomato genome in the hope of breeding better ones.
How close is the tomato genome to a potato?
The tomato’s genome is actually closer to that of a potato. (The two plants share 92 percent of their DNA.) Why map the tomato genome at all?
What is the closest relative to a tomato?
The scientists sequenced the genomes of both Heinz 1706, a variety used to make ketchup, and the tomato’s closest wild relative, Solanum pimpinellifolium, which lives in the highlands of Peru, where the tomato’s ancestors originated. Their results were published online Wednesday in the journal Nature.
