Leaf, seed, and tuber explants of C. latifolia were inoculated on MS medium supplemented with various concentrations of BAP and IBA, alone or in combinations, to achieve in vitro plant regeneration. Subsequently, antioxidant and antibacterial activities were determined from in vitro and in vivo plant developed. No response was observed from seed culture on MS media with various concentrations o...

Data are presented on three edible species of tuber (<igna frutescens, Eminia entennulifa, and Ipomoea transvaalensis) consumed by Hadza foragers in northern Tanzania. These species are collected almost year-round by Hadza women but previous analyses of their macronutrient composition are variable and provide results based on the analysis of whole tuber. We examined only edible portions of tube...

Quality traits such as flavour and texture are assuming a greater importance in crop breeding programmes. This study takes advantage of potato germplasm differentiated in tuber flavour and texture traits. A recently developed 44,000-element potato microarray was used to identify tuber gene expression profiles that correspond to differences in tuber flavour and texture as well as carotenoid cont...

Hexokinase (HXK) proteins play important roles in catalyzing hexose phosphorylation and sugar sensing and signaling. To investigate the roles of HXKs in cassava tuber root development, seven HXK genes (MeHXK1-7) were isolated and analyzed. A phylogenetic analysis revealed that the MeHXK family can be divided into five subfamilies of plant HXKs. MeHXKs were clearly divided into type A (MeHXK1) a...

BEL1-like transcription factors interact with Knotted1 types to regulate numerous developmental processes. In potato (Solanum tuberosum), the BEL1 transcription factor St BEL5 and its protein partner POTH1 regulate tuber formation by mediating hormone levels in the stolon tip. The accumulation of St BEL5 RNA increases in response to short-day photoperiods, inductive for tuber formation. RNA det...

Recent surveys of belowground fungal biodiversity in México and USA have revealed many undescribed truffle species, including many in the genus Tuber. Here we describe seven new species: Tuber beyerlei, T. castilloi, T. guevarai, T. lauryi, T. mexiusanum, T. miquihuanense and T. walkeri. Phylogenetic analyses place these species within the Maculatum group, an understudied clade of small truffle...

abstract in order to study the effects of irrigation regimes on yield and some qualitative characteristics of three cultivars of potato (solanum tuberosum l.), an experiment was conducted in 2009 in the research field of the college of agriculture, ferdowsi university of mashhad. a factorial experiment was arranged in a randomized complete block design with three replications. experimental fact...

The application of zeolite to soils increases cation exchange capacity, and as increases nutrient retention capacity. Imbalanced nutrient management is one of the reasons responsible for low yield of potato in Iran. This study was carried out in research field of Islamic Azad University; Arak Branch at central of Iran to evaluate effect of zeolite particles and phosphorus fertilizer on agro-phy...
