Plant Biology: Seedling Emergence through Soil

The resistance encountered by a seedling as it pushes through the soil causes inhibition of stem elongation and stimulates stem thickening, facilitating soil penetration. A new study demonstrates that two proteolytic pathways work in double-negative fashion - one targeting the other - to protect transcription factors central to this response.

Seed dormancy and seedling vigour as influenced by planting time environment and date of harvest in rice (Oryza sativa L.)

Seed dormancy is a genetically inherited trait whose intensity is modified by the environment during seed development and maturation. In order to study the effect of harvest time on the seed quality and optimum time of sowing to obtain good quality seeds, freshly threshed seeds of ten diverse rice genotypes harvested from six environments were evaluated for seed dormancy and seedling vigour ind...

Denitrification as influenced by photosynthetic oxygen production.

An attempt was made to detect interaction between photosynthesizing algae and denitrifying bacteria by cultivating Chlorella sp. with Pseudomonas s t u t d . Denitrification was inhibited by illumination of the mixed culture after a dark period of 3 hr. It is suggested that immediate inhibition is due to the molecular oxygen produced by the suspended algae and distributed homogeneously in the c...
