You may like to visit ZM37, a cloned version of this for the virtual array nimbMaizeV2, corresponding to release 5a (RefGen_v2) gene models. Visit ZM37
This original accession(Zm29) has used the V1 gene models (release 4b, Filtered Gene Set, corresponding to RefGen_v1) as the basis for probe mapping.
----------
Maize inbred B73 was used for constructing the gene atlas. Plants were grown in Plano silt loam soil at the West Madison Agricultural Research Station, Verona, WI during Summer 2008. During field preparation, 200 kg/acre of Urea (46-0-0) was applied. One day after planting, herbicides including Callisto (142 g/acre), Dual II (710 ml/acre), and Simazine (227 g/acre) were applied. For collection of seed tissues, shoots were covered before silk emergence avoiding any injury to the plants. Plants were self-pollinated on the same day to establish a common time initiation point for the harvest timeline. Greenhouse-grown plants were propagated by growing five plants per pot (30 cm top diameter, 28 cm height, 14.5 L volume) containing Metro-Mix 300 (Sun Gro Horticulture, Bellevue, WA, USA) with no additional fertilization. The growing conditions were 27 deg. C day and 24 deg. C night temperature with a 16h light (5:00am to 9:00pm) and 8h dark regime. Germinating seed tissue was generated by soaking seeds in distilled water in a Petri dish for 12h and then placing seeds between layers of moist paper towels for another 12h to allow germination. The field samples were collected between 8:00am and 10:00am, approximately 3 hours after sunrise. The greenhouse samples were collected between 8:00am and 9:00am, three hours after turning on the lights.

Three biological replicates were collected for each tissue type. For all the tissues except germinating seeds, a biological replicate was constituted by collecting and pooling samples from three competitive randomly chosen plants. For germinating seed, ten randomly chosen seeds were pooled to form a biological replicate. The harvested tissues were immediately frozen in liquid nitrogen and stored at -80 deg. C. Total RNA was extracted using TRIZOL reagent (Invitrogen, http://www.invitrogen.com) following the manufacturer's protocol, and purified using RNeasy MinElute Cleanup Kit (Qiagen, http://www.qiagen.com) following the manufacturer's instructions.
