Genome-Wide Identification and Expression Analysis of Pathogenesis-Related Protein 1 in Sweet Potato and Its Two Relatives. [PDF]

Food Sci Nutr
Pathogenesis‐related Protein 1 (PR1) is a core component of plant innate immunity. We identified 33, 50, and 36 PR1 genes in Ipomoea batatas, Ipomoea trifida, and Ipomoea triloba. Phylogenetic analysis clustered them into 5 groups. Two diploid wild species show high flower/flower‐buds expression, and most sweet potato PR1s are downregulated under ...

Corallorhiza striata is the first example of a pseudocopulatory orchid in North America and an instance of "double deception" in fully mycoheterotrophic plants. [PDF]

Am J Bot
Abstract Premise Orchids have many pollination strategies, from highly species‐specific mutualisms with insects to deceit pollination, including sexual deception. The family also has the most leafless, parasitic species (mycoheterotrophs) of any plant family.

Dominant Species Drive Biomass and Diversity Responses to Nutrient Inputs. [PDF]

Ecol Evol
In a mesic grassland co‐limited by nitrogen and phosphorus, responses in plant community diversity and particularly of dominant species do not always correspond to responses in aboveground net primary productivity and functional group biomass production.

Several plant self-incompatibility systems may be controlled by atypical receptor-ligand interactions. [PDF]

Plant J
SUMMARY Self‐incompatibility (SI) is the single most important mechanism utilized by flowering plants to avoid self‐fertilization, thus preventing inbreeding and promoting outcrossing. Many plant SI systems are genetically controlled by a multi‐allelic S‐locus, containing two tightly linked genes that encode the female and male S‐determinants.

Chemical Characterization and Allelopathic Effects of Ambrosia psilostachya (Asteraceae). [PDF]

Chem Biodivers
ABSTRACT Ambrosia spp. have been introduced and distributed across different continents as an invasive alien plant species. The present study aimed to identify the chemical components of essential oil isolated from different parts of Ambrosia psilostachya and evaluate the phytotoxic effect of its aqueous extracts on the growth parameters of Phaseolus ...

Genome-wide identification, structural and gene expression analysis of the bZIP transcription factor family in sweet potato wild relative Ipomoea trifida

BMC Genetics, 2019
Background The basic leucine zipper (bZIP) transcription factor is one of the most abundant and conserved transcription factor families. In addition to being involved in growth and development, bZIP transcription factors also play an important role in ...

Evaluation of the viability of old seeds of several important agricultural weeds [PDF]

Pesticidi i Fitomedicina
Persistent seed banks are equally important in agriculture and invasion biology. While seed vitality persistence exemplifies an eternal uphill battle for weed control in agriculture, it signals a potential invasiveness of species in invasion biology ...
