Diallel analysis of sweetpotatoes for resistance to sweetpotato virus disease

Euphytica, 2002
Sweetpotato virus disease (SPVD) is due to the dual infection and synergistic interaction of Sweetpotato feathery mottle potyvirus (SPFMV) and Sweetpotato chlorotic stunt crinivirus(SPCSV), and causes up to 98% yield loss in sweetpotato in East Africa.

Metabolomic and Transcriptomic Analyses of the Flavonoid Biosynthetic Pathway for the Accumulation of Anthocyanins and Other Flavonoids in Sweetpotato Root Skin and Leaf Vein Base.

Journal of Agricultural and Food Chemistry, 2022
Sweetpotato [Ipomoea batatas (L.) Lam.] is a major tuberous root crop that is rich in flavonoids. Here, we discovered a spontaneous mutation in the color of the leaf vein base (LVB) and root skin (RS) in the Zheshu 81 cultivar.

Resistance in Sweetpotato to Sweetpotato Weevil

International Journal of Tropical Insect Science, 1987
Sweetpotato weevil, Cylas formicarius formicarius F is the most destructive pest of sweetpotato, Ipomoea batatas in tropical and subtropical regions. The larvae and adults feed on sweetpotato roots and crowns. For the past 12 years we have been screening sweetpotato germplasm for resistance to this pest in order to breed an agronomic cultivar with ...

SWEETPOTATO LEAF CURL VIRUS AND RELATED GEMINIVIRUSES IN SWEETPOTATO

Acta Horticulturae, 2002
Sweetpotato leaf curl diseases have been reported in Taiwan, Japan, and the United States. The causal agent is the whitefly transmitted geminivirus, Sweetpotato leaf curl virus (SPLCV). Viral DNA can be detected in plant samples using polymerase chain reaction (PCR) with SPLCV-specific primers.

Alleviating sweetpotato salt tolerance through exogenous glutathione and melatonin: A profound mechanism for active oxygen detoxification and preservation of photosynthetic organs.

Chemosphere
Salt stress profoundly impacts sweetpotato production. Exogenous glutathione (GSH) and melatonin (MT) promoted plant growth under stress, but their specific roles and mechanisms in sweetpotato salt tolerance need exploration.

SNP loci identification and KASP marker development system for genetic diversity, population structure, and fingerprinting in sweetpotato (Ipomoea batatas L.)

BMC Genomics
Sweetpotato (Ipomoea batatas L.), an important food and industrial crop in the world, has a highly heterozygous hexaploid genome, making the development of single nucleotide polymorphism (SNP) markers challenging.

Biochemical mechanism of chlorine dioxide fumigation in inhibiting Ceratocystis fimbriata and black rot in postharvest sweetpotato.

Food Chemistry
The inhibitory properties and underlying mechanism of chlorine dioxide (ClO2) fumigation on the pathogen Ceratocystis fimbriata (C. fimbriata) and resultant sweetpotato black rot were investigated in vitro and in vivo.

Viruses in Sweetpotato

2012
Sweetpotato in the Mediterranean is mainly grown in Egypt, Spain, Portugal, and Israel. Yields vary from 34 tons/ha in Israel to 7.8 tons/ha in Portugal. As sweetpotatoes are vegetatively propagated, the differences in yields are probably due to the quality in the propagation material, mainly infection by various viruses.

The sweetpotato β-amylase gene IbBAM1.1 enhances drought and salt stress resistance by regulating ROS homeostasis and osmotic balance.

Plant physiology and biochemistry : PPB, 2021
Abiotic stressors, such as drought and high salinity, seriously affect plant growth, productivity, and quality. Maintaining reactive oxygen species (ROS) homeostasis and osmotic balance plays a crucial role in abiotic stress tolerance.

Fumigation of Sweetpotatoes with Methyl Bromide for Control of the Sweetpotato Weevil

Journal of Economic Entomology, 1940
The sweetpotato weevil (Cylas formicarius (F.)) is at present found in Texas, Louisiana, Mississippi, Alabama, Florida, and Georgia. It attacks the vines and roots of the sweetpotato, making the roots unfit for human consumption. The entire egg, larval, and pupal stages and part of the adult stage are spent within the vines or roots.
