Autophagosome development and chloroplast segmentation occur synchronously for piecemeal degradation of chloroplasts

eLife
Plants distribute many nutrients to chloroplasts during leaf development and maturation. When leaves senesce or experience sugar starvation, the autophagy machinery degrades chloroplast proteins to facilitate efficient nutrient reuse.

PDM4, a Pentatricopeptide Repeat Protein, Affects Chloroplast Gene Expression and Chloroplast Development in Arabidopsis thaliana

Frontiers in Plant Science, 2020
Extensive studies have been carried out on chloroplast gene expression and chloroplast development; however, the regulatory mechanism is still largely unknown.

The effect of experimental hybridization on cognition and brain anatomy: Limited phenotypic variation and transgression in Poeciliidae

Evolution, Volume 76, Issue 12, Page 2864-2878, December 2022., 2022
Abstract Hybridization can promote phenotypic variation and often produces trait combinations distinct from the parental species. This increase in available variation can lead to the manifestation of functional novelty when new phenotypes bear adaptive value under the environmental conditions in which they occur. Although the role of hybridization as a

A panoramic view of cotton resistance to Verticillium dahliae: From genetic architectures to precision genomic selection

iMeta, EarlyView.
This study identified 10 reliable quantitative trait loci (QTLs) governing cotton resistance to V. dahliae in various environments through a genome‐wide association analysis (GWAS) using an upland cotton population. The pyramid of these 10 elite alleles reduced the disease index of cotton to V. dahliae from 70 to 20.

A PPR Protein RFCD1 Affects Chloroplast Gene Expression and Chloroplast Development in Arabidopsis

Plants
Chloroplast development is a highly complex process, involving many regulatory mechanisms that remain poorly understood. This study reports a novel PPR protein, RFCD1 (Regulation Factor of Chloroplast Development 1).

Homogenisation of water and sediment bacterial communities in a shallow lake (lake Balihe, China)

Freshwater Biology, Volume 68, Issue 1, Page 155-171, January 2023., 2023
Abstract Planktonic and benthic bacterial communities hold central roles in the functioning of freshwater ecosystems and mediate key ecosystem services such as primary production and nutrient remineralisation. Although it is clear that such communities vary in composition both within and between lakes, the environmental factors and processes shaping ...

Seagrasses under stress: Independent negative effects of elevated temperature and light reduction at multiple levels of organization

Limnology and Oceanography, EarlyView.
Abstract Seagrasses are important foundation species, which support coastal biodiversity and provide socioeconomic benefits. However, seagrasses are threatened by anthropogenic changes, including the elevated temperature associated with marine heatwaves (MHWs) and light limitation from eutrophication or increased sedimentation.

The microbial community spatially varies during a Microcystis bloom event in Lake Kinneret

Freshwater Biology, Volume 68, Issue 2, Page 349-363, February 2023., 2023
Abstract Cyanobacterial blooms in lakes frequently display high spatial heterogeneity, which may drive temporal changes in microbial community structure. Here we report on the spatial (horizontal and vertical) structure of the cyanobacteria community and of the co‐occurring heterotroph microbial community during a major lake‐wide bloom event at Lake ...

Chloroplast Translation Elongation Factor EF-Tu/SVR11 Is Involved in var2-Mediated Leaf Variegation and Leaf Development in Arabidopsis

Frontiers in Plant Science, 2019
Chloroplasts are semiautonomous organelles, retaining their own genomes and gene expression apparatuses but controlled by nucleus genome encoded protein factors during evolution.

Host control and nutrient trading in a photosynthetic symbiosis [PDF]

arXiv, 2015
Photosymbiosis is one of the most important evolutionary trajectories, resulting in the chloroplast and the subsequent development of all complex photosynthetic organisms. The ciliate Paramecium bursaria and the alga Chlorella have a well established and well studied light dependent endosymbiotic relationship.
