Light in the dark
Article Abstract:
The cloning of a gene that regulates how plants react to light has been achieved for the first time. X.-W. Deng and coworkers produced duplicates of the constitutively photomorphogenic (COPI) gene of the plant Arabidopsis thaliana. COPI belongs to a class of genes that govern plant phototransduction or growth in response to light. Studies of mutant plants showed that COPI acts through two previously known protein domains: the zinc-finger region at the amino terminus and the WD-40 proteins.

Today we have naming of parts
Article Abstract:
It has been possible to identify the DNA sequences of chromosomes 2 and 4 from the mustard Arabidopsis thaliana. The researchers found 7,781 protein-coding genes. The gene-rich element of the entire Arabidopsis nuclear genome is around 120 Mb, and therefore 31% of genes should be in chromosomes 2 and 4, with the entire genome coding for around 25,000 proteins. The chromosomal sequences show some of the processes that lead to large-scale genome structure.

The homeotic protein AGAMOUS controls microsporogenesis by regulation of SPOROCYTELESS
Article Abstract:
The microsporogenesis, the process leading to pollen formation, which is induced by AGAMOUS (AG) through activation of the SPOROCYTELESS gene (SPL), a regulator of sporogenesis is shown. The demonstration made suggests that AG controls a specific process during organogenesis by activating another regulator that performs a subset of its functions.
