UNREDUCED MEGAGAMETOPHYTE FORMATION VIA SECOND DIVISION RESTITUTION CONTRIBUTES TO TETRAPLOID PRODUCTIONIN INTERPLOIDY CROSSES WITH ‘ORAH’ MANDARIN (CITRUS RETICULATA)

Frontiers of Agricultural Science and Engineering 2021, Volume 8, Issue 2,

Abstract: Also, we demonstrated that 2n megagametophyte formation in ‘Orah’ mandarin result in tetraploidThese tetraploid plantlets were genotyped using eight pericentromeric SNP markers and nine centromereBased on the genotypes of the 2n megagametophytes, the parental heterozygosity rates in 16 SNP loci andall 2n megagametophytes were less than 50%, indicating that second division restitution was the mechanismunderlying 2n megagametophyte formation at both the population and individual levels.

Frontiers of Agricultural Science and Engineering 2018, Volume 5, Issue 4,   Pages 475-484 doi: 10.15302/J-FASE-2018241

Abstract:

At an early immature growth stage of citrus, a hyperspectral camera of 369–1042 nm was employedto acquire 30 hyperspectral images in order to detect immature green fruit within citrus trees undernm, 563 and 677 nm, and 804 and 962 nm were used to construct a classifier to identify the potential citrusThen, a marker-controlled watershed segmentation based on wavelet transform was applied to obtain potentialThe developed algorithm showed a great potential for identifying immature green citrus for an early yield

Abstract: Wheat stripe rust caused by f. sp. is one of the most devastating diseases of wheat worldwide and resistant cultivars are vital for its management. Therefore, investigating the heterozygosity of the pathogen is important because of rapid virulence changes in isolates heterozygous for avirulence/virulence. An isolate of f. sp. was selfed on to determine the heterozygosity for avirulence/virulence loci. One hundred and twenty progeny isolates obtained from this selfing were phenotyped using 25 lines of wheat containing genes and genotyped with 96 simple sequencing repeat markers, with 51 pathotypes and 55 multi-locus genotypes being identified. All of these were avirulent on lines with , , , and and virulent on lines with , and , indicating that the parental isolate was homozygously avirulent or homozygously virulent for these loci. Segregation was found for wheat lines with , , , , , , , , , , , , , , , and . The 17 cultivars to which the was identified as heterozygous with respect to virulence/avirulence should not be given priority in breeding programs to obtain new resistant cultivars.
