Open AccessDifferentiation in the genetic basis of stem trichome development between cultivated tetraploid cotton species
Cotton stem trichomes and seed fibers are each single celled structures formed by protrusions of epidermal cells, and were found sharing the overlap** molecular mechanism. Compared with fibers, cotton stem t...

GaHD1, a candidate gene for the Gossypium arboreum SMA-4 mutant, promotes trichome and fiber initiation by cellular H2O2 and Ca2+ signals
Cotton fibers are initiated from the epidermal cells of the ovule before or on the day of anthesis. Gossypium arboreum SMA-4 mutant contains recessive mutation (sma-4(ha)) and has the phenotypes of fibreless seed...

Identification and map** of a photoperiod response gene (QPpd.zafu-4A) on wild emmer wheat (Triticum turgidum L.) chromosome 4AL
Heading date (HD) is an important agronomic trait, influencing directly or indirectly yield and quality traits. Previous experiments showed that the chromosome arm substitution line (CASL) 4AL of wild emmer in...

Cot-based sampling of genomes for polymorphic low-copy DNA
DNA polymorphisms are powerful tools for many evolutionary and genomic studies in plants including molecular breeding. Single nucleotide polymorphisms (SNPs) are the most elemental DNA marker for genomic studi...

Open AccessAnalyses of the sucrose synthase gene family in cotton: structure, phylogeny and expression patterns
In plants, sucrose synthase (Sus) is widely considered as a key enzyme involved in sucrose metabolism. Several paralogous genes encoding different isozymes of Sus have been identified and characterized in mult...

Comparative Genomics of Cotton and Arabidopsis
Upland cotton (G. hirsutum), a tetraploid species, evolved from a reunion of two diploid species (most probably G. herbaceum and G. raimondii with A and D genomes respectively) about 1-2 million year ago. Cytogen...
