“…The nine genes may play important roles in storage root development in sweet potato. Pectin is important for cell wall properties and storage root development 42,43 . Two genes involved in pectin biogenesis and acetylation were identi ed, arabinosyltransferase 1 (ARAD1) and pectin acetylesterase 8-like (PAE8) 44,45 .…”

The hexaploid sweet potato is one of the most important root crops worldwide. However, its genetic origins, especially that of its tetraploid progenitor, are unclear. In this study, we conceived a pipeline consisting of a genome-wide variation-based phylogeny and a novel haplotype-based phylogenetic analysis (HPA) to determine that the tetraploid accession CIP695141 of Ipomoea batatas 4x from Peru is the tetraploid progenitor of sweet potato. We detected biased gene exchanges between subgenomes. The B1 to B2 subgenome conversions were almost 3-fold higher than the B2 to B1 subgenome conversions. Our analyses revealed that the genes involved in storage root formation, sugar transport, stress resistance, and maintenance of genome stability have been selected during the speciation and domestication of sweet potato. This study sheds lights on the evolution of sweet potato and paves a way for the improvement of sweet potato.

Fruit textural characteristics can affect the storage, transportation, and processing of plum (Prunus salicina Lindl) in commercial production. We analyzed 23 plum cultivars with marked differences in fruit traits. Basic physicochemical indicators and textural characteristics of the fruits were determined using puncture testing and texture profile analysis. Furthermore, through the combined application of cluster analysis and principal component analysis, the indexes were simplified to three relatively independent dimensions, comprehensively reflecting the hardness, size, and flexibility of plum fruit. Our results show a high positive correlation among textural characteristics such as hardness, springiness, gumminess, and chewiness, whereas toughness and brittleness were negatively correlated. In addition, physicochemical properties were correlated to the texture traits. The weight and size of the plum fruit were related to hardness, adhesiveness, and chewiness. The soluble solids and water content contributed to the hardness, cohesiveness, and resistance to chewing. Cluster analysis revealed three distinct clusters: Cluster I represented by ‘Meiguihong’ with high hardness and a chewable texture; Cluster II represented by ‘Siyuecui’, ‘Cuimi’, and ‘Qingcui’ with a hard and brittle texture; and Cluster III represented by ‘Jinmi’, ‘Taoli’, and ‘Oishiwase’ with a soft and tough texture. The results of this study provide a significant theoretical foundation for quality evaluation, and classification of plum fruit characteristics, thus providing insights for further breeding of plum varieties.

“…The 'Yushu No 10′ have more than twice soluble pectin content than 'Mianfen No 1′, but the unsolvable pectin ingredient was lower than that of 'Mianfen No 1′. It has been an important correlation of gumminess and chewiness between hemicellulose activity of 'Yushu No 10' , and 'Mianfen No 1′ having an unimportant correlation with Cel, PG, HCL, and β-Gal enzymes [115].…”

Solanum Tuberosum - A Promising Crop for Starvation Problem

View full text Add to dashboard Cite

Potato, Solanum tuberosum, the most important non-grain food crop and essential crop globally, has been widely cultivated around the world for centuries. The significance of this plant is increasing due to high nutritional value of the tubers combined with the simplicity of its propagation. As a plant organ, tuber of potato, is mainly edible part of it and popular as nutrient for almost all nations. Tuberization in potato is a very complex biological occurrence affected by numerous ecological signals, genetics, plant nutrition and several different hormones. Many pests including nematodes limit potato tuber development that plant hormones play roles in nematode feeding cell formation. Parasitic nematodes, important pests which cause damage to plants, tubers, suck up nutrients from plants and weaken plant development and yield losses. Many genes involve in tuber development and plant response nematodes. The aim of this chapter is to demonstrate the new advances in the field of molecular host-nematode interactions and tuber development.
