Itaconic acid is an important organic acid used in the chemical industry. Aspergillus terreus strain IFO6365 is one of the highest-yielding itaconic acid-producing wild-type strains. Here, we report the draft genome sequence of IFO6365, enhancing the understanding of the role and biosynthesis of itaconic acid in this fungus.

Aiming to evaluate the effects of soil coverage and fertirigation frequency on pepper yield cv. 'Tabasco' planted in two soils: Yellow Red Latossol (Sandy loam soil) and Red Argissol (Clay soil), an experiment was carried out at Universidade de So Paulo -USP, Escola Superior de Agricultura "Luiz de Queiroz" -ESALQ, located in Sao Paulo estate, Brazil, from May 2007 to April 2008. The experimental design was based on a randomized complete blocks in a 2 x 4 factorial scheme with four replications. The treatments consisted of the combination of two soil coverage (silvered polyethylene film and no film coverage) with four fertirrigation frequencies (24, 12, 3 e 1 / three days). The silvered polyethylene film decreased the total fresh mass of fruits per plant, total number of fruits, fruit mean mass and total dry mass of fruits for the sandy loam and clay soil. The plastic mulching didn't show effect on the dry mass percentage of fruits, water use efficiency, nitrogen use efficiency, potassium use efficiency and NPK use efficiency for the clay soil, and nitrogen use efficiency, phosphor use efficiency and NPK use efficiency for the sandy loam.However the plastic mulching increased the dry mass percentage of fruits, water use efficiency and potassium use efficiency for the sandy loam soil. Average fertirrigation frequencies didn't increase the total fresh mass of fruits per plant, total number of fruits, fruit mean mass, dry mass percentage of fruits, total dry mass of fruits, water use efficiency, nitrogen use efficiency, phosphor use efficiency, potassium use efficiency and NPK use efficiency for the sandy loam and clay soil.
