Subject:: Diospyros kaki; acetaldehyde; astringency; coagulation; cultivars; fruiting; genes; leaves; persimmons; pollination; tannins
Abstract:: ... Pollination constant non-astringency (PCNA)-type persimmons are the most desirable cultivar because the fruit loses astringency naturally and does not require any treatments for edibility. The mechanism of natural astringency loss in Chinese PCNA (C-PCNA)-type persimmon is probably related to the coagulation of soluble tannins into insoluble tannins, which is quite different from that in the Japan ...

Abstract:: ... Second-year traits of growth, stem form, terminal flushing, and survival were assessed in 1770 ramets from 295 clones of 16 full-sib families of Castanea spp. Additive, dominance, and epistatic genetic variances were estimated in a clonally replicated incomplete 5 × 4 factorial test. Parents of the mating design were selected mainly on their phenotypes for wood quality (Castanea sativa traditional ...

Abstract:: ... A fundamental goal of evolutionary biology is to understand how environment shapes genetic variation through its effect on demographic processes and through natural selection. In non-model species, transcriptome sequencing generates large single nucleotide polymorphism (SNP) panels to disentangle these influences. Quercus lobata (valley oak) offers an excellent system for such analyses because it ...

Abstract:: ... Gibberellins (GAs) have been widely used for many years to induce seedless grapevine and increase fruit set in production. However, the role of GAs and how they crosstalk with auxin and cytokinin during fruit set in grapevine remains unclarified. To investigate their role, GA₃, 4-chlorophenoxyacetic acid (4-CPA), 6-benzylaminopurine (6-BA), and different hormone combinations were applied to unpoll ...

Abstract:: ... Selective logging systems have been used to prevent the rapid decline of forest resources in Southeast Asia, but little is known about the impacts of selective logging on the genetic diversity of Southeast Asian rainforests. We evaluated the effects of silvicultural systems with differing cutting rotations and enrichment planting regimes on the genetic diversity of Shorea parvifolia, an abundant a ...

Abstract:: ... Plant terpenes constitute a large class of compounds and have numerous biological roles as either primary or secondary metabolites. Terpene synthases (TPSs) play key roles on catalyzing the formation of different terpenes; they are divided into seven subfamilies based on sequence relatedness (TPSa–h). TPS-a proteins catalyze the formation of sesquiterpenes and diterpenes in plants. Physic nut (Jat ...

Abstract:: ... Orographic and climatic influences during the Pleistocene have had a crucial role on interspecific divergence and population demography during speciation. However, associations between demographic histories of closely related species and related climatic events, especially in north and northeast China, are still underexplored. Genetic analyses with four chloroplast DNA and two nuclear genes and sp ...

Abstract:: ... In most plants, the contributions of pollen and seed flow to their genetic structures are generally difficult to disentangle. For typical wind-pollinated and wind-dispersed species Engelhardia roxburghiana in a 20-ha natural forest plot in lower subtropic China, because the prevailing wind directions change during its pollen release and seed dispersal seasons, we could compare its genetic structur ...

Abstract:: ... Cycas debaoensis is a critically endangered cycad species endemic to China. This species is found on two kinds of habitats according to the edaphic differences, sand and karst. A previous chloroplast DNA (cpDNA) study indicated that C. debaoensis had low genetic variation within populations and high genetic differentiation among populations. Because maternally inherited cpDNA does not fully charac ...
