Abstract:
... The OsLCD gene, which has been implicated in cadmium (Cd) accumulation in rice, might be a useful target for CRISPR/Cas9 editing. However, the effects of OsLCD gene editing on Cd accumulation, plant growth, and yield traits remain unknown. Here, we used CRISPR/Cas9 to generate oslcd single mutants from indica and japonica rice cultivars. We also generated osnramp5 single mutants and oslcd osnramp5 ...

Abstract:
... Simple sequence repeat (SSR) microsatellite markers have been extensively used to identify duplication and analyse genetic diversity in germplasm collections of apple. Here, we present findings from the use of a standard set of SSR loci in the managed repropagation of a significant international germplasm collection: the UK National Fruit Collection (NFC). A subset of eight SSR loci was deemed suf ...

Abstract:
... Core germplasm banks are constructed to provide breeders with maximum genetic diversity concomitant with minimum genetic redundancy for a faster breeding process with the least number of accessions possible. In this study, we collected a cotton germplasm collection including 477 cotton varieties cultivated in China and 26 introduced from America and the Soviet Union. Three primary germplasm banks ...
... Direct planting (i.e. the planting of seed roots) in sweet potato results in the formation of two root types – ‘mother’ and ‘daughter’ roots. High and stable daughter root yields are necessary to improve the acceptance of direct planting cultivation because mother roots have no commercial value. To establish a basis for the effective breeding, the root traits of 28 sweet potato genotypes cultivate ...

Abstract:
... Fusarium wilt (FW), caused by Fusarium oxysporum f. sp. pisi (Fop), has always been an important disease affecting pea production and causing severe yield losses in most pea-growing areas worldwide. Growing resistant pea cultivars is the most economical and effective method for controlling the disease. In this study, firstly, 21 Fusarium oxysporum isolates were identified as races 1 and 5 of Fop b ...
... Plants with the flower color phenotype of double-color flowers are very precious and attractive and can usually be regarded as valuable germplasm resources for studying and improving flower color. This paper summarizes the coloring mechanism of double-color flowers in plants from three aspects: the formation of double-color flowers, the physiological factors affecting the coloring difference of do ...
... Mesosetum chaseae, known as “grama do cerrado” (savannah grass), is an important native forage plant in the Pantanal region, in the state of Mato Grosso do Sul, Brazil. However, no records of molecular markers at DNA level to evaluate the genetic diversity in the germplasm collection of M. chaseae are available. Current study hypothesizes that ISSR markers may be useful to evaluate genetic diversi ...
... BACKGROUND: Common vetch (Vicia sativa L.) is an annual legume with excellent suitability in cold and dry regions. Despite its great applied potential, the genomic information regarding common vetch currently remains unavailable. METHODS AND RESULTS: In the present study, the whole genome survey of common vetch was performed using the next-generation sequencing (NGS). A total of 79.84 Gbp high qua ...
... Amaranth (Amaranthus spp.) is an underutilized crop increasing in popularity as a grain and as a leafy vegetable. It is rich in protein, minerals, and vitamins, and adapts well to a range of production systems. Currently, the lack of improved cultivars limits the use of the crop. Breeding‐improved cultivars requires access to large collections of amaranth biodiversity stored in genebanks. The task ...

Abstract:
... A plum collection located in the island of La Palma, Canary Islands, composed of twenty-nine European and Japanese plums was analyzed using nine simple sequence repeat (SSR) highly polymorphic loci. First, a cytometry flow analysis was performed to determine the ploidy level. Sixteen accessions turned out diploid and thirteen hexaploid. According to morphological characteristics, fourteen of the s ...

Abstract:
... Medium-term in vitro plant conservation is an alternative for maintaining germplasm banks in breeding programs. The aim of this study was to evaluate the efficiency of the gibberellin inhibitors paclobutrazol (PBZ) and trinexapac-ethyl (TNE) for in vitro conservation by minimal growth in anthurium, sugarcane, and agave. For the establishment of the conservation system, shoots of the aforementioned ...
... Germ plasm is a substance capable of driving naive cells toward the germ cell fate. Germ plasm has had multiple independent origins, and takes on diverse forms and functions throughout animals, including in insects. We describe here recent advances in the understanding of the evolution of germ plasm in insects. A major theme that has emerged is the complex and convoluted interactions of germ plasm ...

Abstract:
... Consensus sequences have the potential to help classify the structure and function of proteins and highlight key regions that may contribute to their biological properties. Often, the level of significance will track with the extent of sequence conservation, but this should not be considered universal. Arg and Lys dominate a position adjacent to the N1 and C2 carbonyl of flavin mononucleotide (FMN ...
... The present work shows the results of a seven-year project aimed at rescuing the winter squash (Cucurbita maxima Duchesne) landrace ‘Berrettina di Lungavilla’, which is grown in the Po flood plain (Northern Italy). The local community was involved in the rescue project, according to a participative breeding technique. The steps of project development were: (i) establishment of a working group and ...
... Phenotypic characterization on historical breeding lines and wild genetic resources from the 1950′s to 1990′s of the rubber-bearing plant guayule (Parthenium argentatum A. Gray) and hybrids was conducted. Variation among germplasm on seed weight and germination was determined along with leaf traits and trichomes using image analyses. Flow cytometry was performed to estimate diversity in ploidy lev ...

Abstract:
... Garlic (Allium sativum), an asexually propagated vegetable and medicinal crop, has abundant genetic variation. Genetic diversity evaluation based on molecular markers has apparent advantages since their genomic abundance, environment insensitivity, and non-tissue specific features. However, the limited number of available DNA markers, especially SSR markers, are insufficient to conduct related gen ...

Abstract:
... In Indonesia, sugarcane and sugar production during the last ten years (2010–2019) fluctuated considerably and showed a declining trend due to several reasons. The achievements of sugarcane production were mainly influenced by the availability of superior sugarcane varieties developed by the domestic sugarcane breeding programs. Historically, sugarcane breeding in Indonesia was started during the ...

Abstract:
... Rhizanthes is a holoparasitic plant of the Rafflesiaceae, and, just like Rafflesia, its host is Tetrastigma (Vitaceae). Unlike Rafflesia, very little research has been conducted on Rhizanthes other than a few studies focusing on its taxonomy and anatomy, and limited studies on its propagation, despite some ethnomedicinal uses in several regions of Indonesia. Wild populations of Rhizanthes are decl ...
