brassinosteroid/potato

The brassinosteroid (BS) profiles in shoots and roots of the potato plants were shown to be organ-specific and dependent on the term of variety ripening. The amount of all studied groups of steroid phytohormones proved to be an order of magnitude higher in roots than in shoots. In roots, the

This is the first study to show that brief pretreatment of potato plants with two brassinosteroids differing in structure causes in plants the ability to react to delayed salt stress by accumulation of compounds with antioxidant activity and by increased salt tolerance.

Sweepoviruses have been identified globally and cause substantial yield losses and cultivar decline in sweet potato. This study aimed to investigate the interaction between sweepovirus and plant host by analyzing the function of the viral protein C4 of Sweet potato leaf curl virus-Jiangsu

Brassinosteroids (BRs), a new class of steroid hormones, are involved in the regulation of plant cell elongation and seed germination. Nevertheless, the molecular mechanism of the effect of BRs on tuber sprouting remains largely unknown. In this study, quantitative phosphoproteomics was employed to

Field co-infection of multiple viruses results in considerable losses in the yield and quality of storage roots in sweet potato. However, little is known about the molecular mechanisms underlying developmental disorders of sweet potato subjected to co-infection by multiple viruses. Here, a

Brassinosteroids are promising agents for alleviating the negative effects of salinity on plants, but the mechanism of their protective action is far from being understood. We investigated the effect of pretreatment with 24-epibrassinolide (24-EBL) on the photosynthetic and physiological parameters

Although structurally simple, viroids can trigger numerous changes in host plants and cause loss of yield in agronomically important crops. This study investigated changes in the endogenous status of phytohormones and antioxidant enzyme activity in Solanum tuberosum cv. Désirée in response to Potato

Potato (Solanum tuberosum L) is a natural host of Potato spindle tuber viroid (PSTVd) which can cause characteristic symptoms on developing plants including stunting phenotype and distortion of leaves and tubers. PSTVd is the type species of the family Pospiviroidae, and can replicate in the nucleus

Host gene expression changes in the early response to potato virus Y(NTN) interaction were compared in two differently sensitive potato cultivars: the resistant cultivar Santé and the sensitive cultivar Igor. Hybridization of potato TIGR cDNA microarrays allowed us to monitor the expression of

The plant receptor-like kinase somatic embryogenesis receptor kinase 3 (SERK3)/brassinosteroid insensitive 1-associated kinase 1 (BAK1) is required for pathogen-associated molecular pattern (PAMP)-triggered immunity (PTI). Here we show that a distinct member of the SERK family, SERK1, is required

Late blight, caused by Phytophthora infestans (P. infestans), is a devastating disease in potato worldwide. Our previous study revealed that the Solanum andigena genotype 03112-233 is resistant to P. infestans isolate 90128, but susceptible to the super race isolate,

Polycomb Repressive Complexes (PRC1 and PRC2) regulate developmental transitions in plants. AtBMI1, a PRC1 member, represses miRNA156 to trigger the onset of adult phase in Arabidopsis (Arabidopsis thaliana). miRNA156 overexpression (OE) reduces below-ground tuber yield, but stimulates aerial tubers

An emerging area in plant research focuses on antagonism between regulatory systems governing growth and immunity. Such cross talk represents a point of vulnerability for pathogens to exploit. AVR2, an RXLR effector secreted by the potato blight pathogen Phytophthora infestans, interacts with potato

Viroids like Potato spindle tuber viroid (PSTVd) are the smallest known agents of infectious disease-small, highly structured, circular RNA molecules that lack detectable messenger RNA activity, yet are able to replicate autonomously in susceptible plant species. To better understand the possible

Brassinosteroids (BRs) are steroidal phytohormones that regulate various physiological processes, such as root development and stress tolerance. In the present study, we showed that brassinolide (BL) affects potato root in vitro growth in a dose-dependent manner. Low BL concentrations (0.1 and 0.01
