Xff 4834-R ISs are associated with two major chromosomal inversion events, one large DNA deletion event, various gene transfers, and several gene breakdowns.
The coding regions of these genes sum to a total of 53.8 kb and across the five samples, mean coverage of these regions ranged from 39.4× to 68.9×, with 88.9 to 92.8% of bases covered by at least 10 reads (gene-by-gene breakdowns are shown in Supplementary Material, Table S1 and Fig. S1).
It could be due to the additive effects of many slightly dosage-sensitive genes, the breakdown of gene networks, or the uncovering of recessive lethal alleles.
These data provide in vivo evidence for the crucial function of the Notch2 gene in breakdown of germ-cell nests, postnatal apoptosis of oocytes, and formation of primordial follicles.
Tumors have been likened to "wounds that never heal" [ 64], which is reflected by shared expression of genes mediating breakdown of the extracellular matrix, productive chronic inflammation, and angiogenesis.
Ablation of a gene controlling fat breakdown can protect mice from cancer-associated uncontrolled loss of fat and muscle.
Yamamoto et al. (2010) reported that hbd3, a causal gene controlling hybrid breakdown in rice, is located on the cluster of NB-LRR genes.
Surprisingly, we further show mPer2Brdm1 mice [4], with a deletion mutation in the mouse Period2 gene, display the breakdown of such a universal statistical law for resting periods, just as observed in patients with major depressive disorders [3].
The protein product of this gene catalyzes the breakdown of neurotoxic quinolinate in the tryptophan nicotinamide adenine dinucleotide pathway, preventing the intracellular accumula tion of toxic compounds and maintaining neuronal function.
To determine whether disruption of the NRPD1a gene could cause breakdown of SI in SRKb-SCRb transformants of accessions that express a developmentally stable SI response, an nrpd1a mutant in the C24 background (Zheng et al. 2008) was obtained and crossed to a C24[ SRKb-SCRb] plant.
