Cacao is a crop of global relevance that faces constant demands for improved bean ***,little is known about the genomic regions controlling the crop yield and genes involved in cacao bean ***,to identify the quantitative trait loci(QTL)associated with cacao yield and bean filling,we performed a QTL mapping in a segregating mapping population comprising 459 trees of a cross between‘TSH 1188’and‘CCN 51’.All variables showed considerable phenotypic variation and had moderate to high heritability *** identified 24 QTLs using a genetic linkage map that contains 3526 single nucleotide polymorphism(SNP)*** analysis at the significant QTL region on chromosome IV pointed to the alleles from the maternal parent,‘TSH 1188’,as the ones that affect the cacao yield components the *** recombination events identified within these QTL regions allowed us to identify candidate genes that may take part in the different steps of pod growth and bean *** candidate genes seem to play a significant role in the source-to-sink transport of sugars and amino acids,and lipid metabolism,such as fatty acid *** SNP markers mapped in our study are now being used to select potential highyielding cacao varieties through marker-assisted selection in our existing cacao-breeding experiments.

很喜欢冯骥才的这句话。坚韧,是生命最鲜活的底色。就如设计,灵感乍现的那一刹那,我们往往心藏窃喜。因为,这是最接近神性的时刻。生活在这万千世界,城市、自然、人文构成了一个泛生态圈。我们游走于真实与虚拟之间,坐看日夜更迭,霓虹与云朵交替,感知被无限地放大,也往往外化成有感的设计形态。那些热烈绽放着的设计,常常令人心生欢喜,心存敬畏。
