Early Seed Development

Abstract Background SWEETs (Sugar Will Eventually be Exported transporters) function as sugar efflux transporters that perform diverse physiological functions, including phloem loading, nectar secretion, seed filling, and pathogen nutrition. The SWEET gene family has been identified and characterized in a number of plant species, but little is known about in Litchi chinensis, which is an important evergreen fruit crop. Results In this study, 16 LcSWEET genes were identified and nominated according to its homologous genes in Arabidopsis and grapevine. Multiple sequence alignment showed that the 7 alpha-helical transmembrane domains (7-TMs) were basically conserved in LcSWEETs. The LcSWEETs were divided into four clades (Clade I to Clade IV) by phylogenetic tree analysis. A total of 8 predicted motifs were detected in the litchi LcSWEET genes. The 16 LcSWEET genes were unevenly distributed in 9 chromosomes and there was one pairs of segmental duplicated events by synteny analysis. The expression patterns of the 16 LcSWEET genes showed higher expression levels in reproductive organs. The temporal and spatial expression patterns of LcSWEET2a and LcSWEET3b indicated they play central roles during early seed development. Conclusions The litchi genome contained 16 SWEET genes, and most of the genes were expressed in different tissues. Gene expression suggested that LcSWEETs played important roles in the growth and development of litchi fruits. Genes that regulate early seed development were preliminarily identified. This work provides a comprehensive understanding of the SWEET gene family in litchi, laying a strong foundation for further functional studies of LcSWEET genes and improvement of litchi fruits.

Early Seed Development

The early embryo and endosperm development patterns of five annual taxa and three perennial taxa of the genus Secale were analyzed. The results showed that there was considerable variation in the speed of early embryo and endosperm development within the genus Secale, and that the developmental patterns of the annual and perennial taxa overlapped. Comparisons indicated that DNA content per se did not have any influence on the speed of early embryo development or aberrant endosperm nucleus production in either the annual or perennial taxa. However, comparisons between the percent telomeric heterochromatin and the number of embryo cells produced showed a significant positive correlation in the annual taxa, and a nonsignificant correlation in the perennial taxa. There was a positive correlation between the number of aberrant endosperm nuclei and percent telomeric heterochromatin in the annual taxa, while the perennial taxa showed a nonsignificant but negative correlation. The results suggest that percent telomeric heterochromatin has a different effect on early seed development in the annual taxa than in the perennial taxa.Key words: Secale, heterochromatin, DNA content, embryo cell cycle.

Developmental Characteristics

Considerable variation was observed in the early embryo and endosperm developmental patterns of several Triticum durum × Secale species (africanum, cereale, dighoricum, kuprijanovii, montanum, segetale, vavilovii) amphiploids. However, the Triticum – S. africanum hybrid was the only one which developed at a faster rate than either of its parents. Its endosperm became cellular and began depositing starch at least 24 h before any previously analyzed cereal. The influence of Secale DNA and heterochromatin on the developmental patterns of the amphiploids was exactly the opposite of that in the genus Secale itself (i.e., as the amount of telomeric heterochromatin increases developmental speed decreases). The results, in general, suggest that the control of Secale developmental characteristics, whether they are genotypic or nucleotypic, are suppressed when placed in a wheat background.Key words: triticale, heterochromatin, interspecific hybrid, wheat embryo.
