Newly described are two new species of Spiloxene Salisb.:  S. nana Snijman from the Bokkeveld Escarpment, Northern Cape Province, is a shade-loving plant with narrow, pale green leaves and small, white or rarely cream-coloured flowers; S. pusilla Snijman from the Matsikamma, Gifberg and Pakhuis Mountains. Western Cape Province, resembles S. nana in habit but the yellow- or white-tepalled flowers which are tetramerous or hexamerous have darkly coloured stamens and style and an ovary with a short, solid, narrow prolongation at the apex. Inhabiting rock overhangs formed by quartzitic sandstone sheets, both species are close allies of S. scullyi (Baker) Garside from Namaqualand.

Abstract A description is provided for Streptomyces ipomoeae. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: On Ipomoea batatas. DISEASE: Soil rot, pox, pit, or ground rot of sweet potato. All underground parts of the plant can be attacked. Dark brown to black spots of varying shapes and sizes are formed on roots, tubers and underground parts of stems. In serious attacks many of the fine feeding roots are either destroyed or more or less malformed. The above-ground parts of the plants then show poor growth and thin, pale green leaves. Yields are drastically reduced on such plants. In the early stages lesions on the root-tubers are covered by the epidermis, but this cracks and breaks up, leaving a hole or pit. These pits can be quite large and may girdle the potato, preventing growth at that point. Continued growth on either side results in a dumbell-shaped, or other misshapen potato. GEOGRAPHICAL DISTRIBUTION: USA, occurring more or less locally in most, if not all, of the States where sweet potatoes are grown. (CMI Map 301, ed. 2, 1975). TRANSMISSION: The disease is soilborne and most infection is thought to take place when plants are set out into already infested fields, but infection can occur in the nursery bed. The pathogen can be spread to new areas in a variety of ways. Infected planting material is probably the most frequent, but contaminated agricultural tools, workers' boots, feet of grazing animals, and even the wheels of vehicles may also play a part. Once established in a field, the organism can continue to live in the soil until the host is present and conditions are right for infection.

Blending compost from various feedstocks may increase the beneficial effects of compost as potting substrate. A factorial treatment combinations included 10 compost combinations, Sunshine Mix and Pro Gro 300S as controls, three compost levels, and three chrysanthemum cultivars. The compost combinations were Compro (CP), poultry litter (PL), PSG polymer dewatered biosolids (PSG), yard trimmings (YT), CP:PL, CP:PSG, CP:YT, PL:PSG, PL:YT, and PSG:YT; all blends were on a 1:1 ratio (v/v). The compost levels were 50%, 75%, 100%; and chrysanthemum cultivars included `Boaldi', `Cherry Davis', and `Yellow Favor'. All treatments were replicated six times. Plants were fertilized with 100 mg/L N from 20N–8.8P–16.6K twice weekly. All compost substrates, except PSG blends produced plants that were shorter than the controls. All compost blends produced similar or greater number of flower than the controls. Plants grown in substrates containing PSG and/or CP produced dark green or green foliages, and other substrates produced plants with pale green leaves. The PSG:PL and PSG: YT blends produced premium-quality plants. All other compost blends produced good-quality plants that were similar to the controls.

Eukaryotic Transcription

Gene expression is an intricately regulated process that is at the basis of cell differentiation, the maintenance of cell identity and the cellular responses to environmental changes. Alternative splicing, the process by which multiple functionally distinct transcripts are generated from a single gene, is one of the main mechanisms that contribute to expand the coding capacity of genomes and help explain the level of complexity achieved by higher organisms. Eukaryotic transcription is subject to multiple layers of regulation both intrinsic — such as promoter structure — and dynamic, allowing the cell to respond to internal and external signals. Similarly, alternative splicing choices are affected by all of these aspects, mainly through the regulation of transcription elongation, making it a regulatory knob on a par with the regulation of gene expression levels. This review aims to recapitulate some of the history and stepping-stones that led to the paradigms held today about transcription and splicing regulation, with major focus on transcription elongation and its effect on alternative splicing.

Tf Gene

SummaryAlthough normally absent from the surface of all circulating cell types, tissue factor (TF) can be induced to appear on circulating monocytes by stimulants like bacterial lipopolysaccharide (LPS) and phorbolesters. Northern analysis of RNA isolated from LPS stimulated human monocytes demonstrates the presence of 2.2 kb and 3.1 kb TF mRNA species. The 2.2 kb message codes for the TF protein. As demonstrated by Northern blot analysis with a variety of TF gene probes, the 3.1 kb message arises from an alternative splicing process which fails to remove 955 bp from intron 1. Because of a stop codon in intron 1 no TF protein is produced from the 3.1 kb transcript. This larger transcript should therefore not be taken into account when comparing TF gene transcription and TF protein levels.
