Role of the tomato MARS1/ROUGH gene encoding a LYSINE‐SPECIFIC HISTONE DEMETHYLASE 1 in adventitious root and fruit skin formation

Journal of Integrative Plant Biology, EarlyView.
The tomato mars1/rough mutant displays enhanced root regeneration and rough fruits due to ectopic cell proliferation. The causal gene encodes a lysine‐specific histone demethylase that normally maintains gene silencing. Its loss alters histone methylation, upregulating several genes, including those B‐type cyclins involved in tissue‐specific cellular ...

Occurrence of parietal and invasive tapetum in Dyckia strehliana (Bromeliaceae): first report for the Family [PDF]

Rodriguésia
Tapetal tissue plays essential roles in the formation of generative cells, as it is related to their nutrition and development in anthers. Among the few species of Bromeliaceae for which tapetal tissue has been describe, most have a secretory tapetum and

Chicken or egg? The evolutionary riddle of CMS and Rf in plants

Journal of Integrative Plant Biology, EarlyView.
Cytoplasmic male sterility (CMS) reduces pollen fertility and nuclear Rf genes restore fertility. This Commentary explores support for the “arms race” and “pre‐adaptation” models for CMS–Rf co‐evolution. CMS and Rf interact dynamically, influencing plant reproduction, stress tolerance, and hybrid seed production, highlighting co‐evolutionary processes ...

Signalling of double strand breaks and deprotected telomeres in Arabidopsis.

Frontiers in Plant Science, 2013
Failure to repair DNA double strand breaks (DSB) can lead to chromosomal rearrangements and eventually to cancer or cell death. Radiation and environmental pollutants induce DSB and this is of particular relevance to plants due to their sessile life ...

ATXR5 and ATXR6 restrict meiotic crossover formation within heterochromatin in Arabidopsis

Journal of Integrative Plant Biology, EarlyView.
The Arabidopsis H3K27 mono‐methyltransferases ATXR5 and ATXR6 repress crossovers within meiotic heterochromatin, are required for heterochromatin condensation and H3K27me1 establishment, and specifically influence the maintenance of DNA methylation in meiocytes.

Ecological Adaptation Mechanisms Underlying Successful Plant Reproduction

Advanced Science
As sessile organisms, plants have evolved sophisticated adaptive strategies to withstand fluctuating and often unpredictable environments. These strategies optimize reproductive traits, enabling plants to sustain reproduction under adverse conditions ...

Giant kelp (Macrocystis pyrifera) gametophytes grow endophytically in red macroalgae: Implications for kelp restoration

Journal of Phycology, EarlyView.
Abstract Giant kelp (Macrocystis pyrifera) forests have declined by 95% in Australia since the 1970s due to climate change. Despite expanding restoration efforts, long‐term recovery is still lacking. Factors influencing recruitment by the microscopic gametophyte phase may represent a key mechanism underpinning the successful recovery and restoration of

Plasmodium Actin‐Like Proteins 3 and 5a Are Required for Subsequent Steps of Mosquito Infection

Molecular Microbiology, EarlyView.
Actin‐like proteins (Alps) are highly conserved, apicomplexan‐specific members of the actin superfamily. Using reverse genetics, we have identified that Alp3 and Alp5a are required at separate steps of transmission of the malaria parasite to its mosquito host.

The cold case of state transition 7 (stt7) mutants of Chlamydomonas reinhardtii, solved by whole‐genome sequencing

New Phytologist, EarlyView.
Long‐read whole‐genome sequencing revealed extensive chromosomal rearrangements and aneuploidy in a widely used Chlamydomonas reinhardtii stt7‐1 mutant. The STT7 gene (shown in red) was found to be split between two rearranged chromosomes, providing a molecular explanation for the long‐standing failure of this mutant in genetic crosses.
