The products of the trithorax gene are required to stably maintain homeotic gene expression patterns established during embryo-genesis by the action of the transiently expressed segmentation genes. We have determined the intron/exon structure of the trx gene and the large alternatively spliced trx RNAs, which are capable of encoding only two protein isoforms. These very large trx proteins diffe...

Crotalaria juncea (Fabaceae), also known as sunn hemp or Indian hemp, is a warm-season legume grown cover crop that provides nitrogen and organic-matter to soils, prevents weed growth suppresses nematode populations (Meagher et al., 2019). In September 2021, root rot symptoms were observed in fields distributed Cocula, Guerrero, Mexico. Diseased plants showed reduced growth, rot, chlorosis, wil...

The plasticity of ageing suggests that longevity may be controlled epigenetically by specific alterations in chromatin state. The link between chromatin and ageing has mostly focused on histone deacetylation by the Sir2 family, but less is known about the role of other histone modifications in longevity. Histone methylation has a crucial role in development and in maintaining stem cell pluripot...

Polycomb-group (PcG) proteins and associated histone modifications play pivotal roles in development, stem cell self-renewal and cancer. These proteins function in different transcriptional repressor complexes that epigenetically modify chromatin and participate in the establishment and maintenance of cell fates [1]. Although many proteins have been reported to associate with PcG protein comple...

RPB1 (which is not present in bacterial RNAP) is not Gene expression in all cells requires synthesis of mRNAs resolved in the structures. by an evolutionarily conserved, multisubunit RNA polyAs RNAP transcribes (Figure 1B), DNA enters the enmerase (RNAP). A series of recent breakthroughs in zyme in the first chamber, termed the jaw-lobe module. X-ray crystallography of RNAP has begun to reveal ...
