Published: February 2019

The plastid genomes of the non-photosynthetic plants Balanophora reflexa and B. laxiflora are among the most GC-biased genomes observed to date. A new study shows that ∼80% of the plastid-derived proteome is represented by only six amino acids, and several genes are in excess of 95% AT.

A gene within a single subclade of NCED genes is triggered in response to both, short- and long-term dehydration treatments, in three model dicot species. During dehydration, some plants can rapidly synthesise the stress hormone abscisic acid (ABA) in leaves within 20 min, triggering the closure of stomata and limiting further water loss. This response is associated with significant transcriptional upregulation of Nine-cis-Epoxycarotenoid Dioxygenase (NCED) genes, which encode the enzyme considered to be rate-limiting in ABA biosynthesis.

The Tapetum Determinant 1 (TPD1) family proteins are known to play a crucial role in the regulation of reproduction in plants, including Cenchrus americanus (pearl millet). However, members of TPD1 family proteins have not been fully identified. The current study aims to identify and characterize the TPD1 family proteins in Cenchrus americanus (L.

A Gram-stain-positive, facultatively anaerobic, rod-shaped strain, designated SPB1-3, was isolated from tree bark. This strain exhibited heterofermentative production of dl-lactic acid from glucose. Optimal growth was observed at 25-40 °C, pH 4.

In order to identify the pathogen responsible for Hedera nepalensis leaf blight and investigate effective biocontrol strategies, samples were collected from 10 significantly infected areas at Southwest Forestry University; four to six infected leaves were gathered from each area, followed by the isolation and purification of strains from the infected plant leaves using tissue isolation and hyphae-purification techniques. We conducted an examination of the biological characteristics and compared the inhibitory effects of different concentrations of Phomopsis sp. (50%, 25%, 16.

Insects and flowering plants are the most abundant and diverse multicellular organisms on Earth, accounting for 75% of known species. Their evolution has been largely interdependent since the so-called Angiosperm Terrestrial Revolution (100-50 Mya), when the explosion of plant diversity stimulated the evolution of pollinating and herbivorous insects. Plant-insect interactions rely heavily on chemical communication via volatile organic compounds (VOCs).
