NOTICE TO CONTRIBUTORS Papers for publication and correspondence on editorial matters should be addressed to the editor, c/o Oxford University Press, Walton Street, Oxford 0X2 6DP. The right of publication in this journal is not restricted to members of the Society and contributions from research workers both in Great Britain and abroad will be welcomed.

Manuscripts should be prepared strictly according to the recommendations printed on the following pages, and should not exceed the equivalent of 5000 words, including figures.

Contributors receive 100 offprints of their articles free of charge. It is regretted that no extra copies can be supplied. Preparation of Manuscripts

GENERAL Manuscripts should be typewritten, double-spaced throughout, with at least a 4 cm margin on the left. Two clearly legible copies must be submitted to the Editor c/o Oxford University Press, Walton Street, Oxford 0X2 6DP. The date of submission should be given on the first page. The style of setting out, sub-division of the text and layout of tables should conform to

that of a current copy of the journal. Authors should suggest a running title of not more than Downloaded from https://academic.oup.com/jxb/issue/31/5 by guest on 23 September 2021 4 words. Only page proofs will be supplied to authors so that no alterations, either additions or deletions, can be permitted. The proofs are simply for the purpose of correcting printing errors. Therefore, manuscripts must be submitted in a final form, fully revised and checked for typo- graphical and other errors. Only in exceptional cases and at the Editor's discretion will it be permitted to make a post-script addition in proof which will be placed at the end of the paper. Authors should write as clearly and concisely as possible. Large bodies of primary data should not be presented, and data may not be presented in both tabular and graphical form. Contributions must be original and have not been submitted for publication elsewhere.

ABSTRACT An Abstract, not exceeding 250 words, will be published at the beginning of each paper; it should contain no discursive matter or references.

PREPARATION FOR PUBLICATION Each submitted manuscript will be referred to at least one expert referee. Authors will be consulted if the paper is considered suitable for publication but alterations are thought desir- able. After these alterations have been included the manuscript must be considered final. Page proofs will be sent to authors for checking before publication and will include illus- trations set in the appropriate place in the type. Proofs will be sent to the first-named author at the address given at the head of the manu- script unless authors have specifically indicated to the contrary. The author will be allowed 14 days in which to return the corrected proof to the publisher. If he fails to do so the Editor reserves the right to correct the proofs himself and to send the material for publication. This procedure is essential if all the material in a given number is not to be delayed by the late receipt of one corrected proof.

SCIENTIFIC NAMES The complete scientific name (, species, and authority, and where appropriate) must be cited for every organism at the timo of first mention. The generic name may be ab- breviated to the initial thereafter except where intervening references to other genera with the same initial could cause confusion. If vernacular names are employed, they must be accom- panied by the correct scientific name on first use.

CHEMICAL NOMENCLATURE The system of The Chemical Society should be followed (see Handbook for Chemical Society Authors, 1961).

UNITS OF MEASUREMENT The metric system is adopted as standard. The system of units known as SI should be used. These will be found in the Royal Society publication Metrication in Scientific Journals, 1968. If non-standard abbreviations must be used they should be defined in the text. [1] ABBREVIATIONS Standard chemical symbols may be used in the text where desirable in the interests of con- oiaeness. For long chemical names and other cumbersome terms, widely accepted abbrevia- tions may be used in the text (e.g. ATP, DNA); the list of standard abbreviations published each year by The Biochemical Society (Pamphlet—Policy of the Journal and Instructions to Authors) is an acceptable guide for the journal. Abbreviations for the names of less common compounds should also be used, but then the full term should be given on first mention. It is confusing and unnecessary to use abbreviations for common English words (e.g. L for light). Dates should be cited thus: 7 June. Unite of measurement should be spelled out except when preceded by a numeral when they should be abbreviated in the standard form: g, mg, ml, etc. and not followed by full stops. Numbers up to ten should be spelled out in the text except when referring to measurements. Fractions are to be expressed as decimals. Numbers higher than ten are to be represented as numerals except at the beginning of a sentence. Downloaded from https://academic.oup.com/jxb/issue/31/5 by guest on 23 September 2021

TABLES Tables should be numbered in arabic numerals and each submitted on a separate sheet with an appropriate legend at the head. The preferred position in the text should be indicated.

LITERATURE CITATION Citations in the text should take the form: Smith and Robinson (1960). If several papers by the same author in the same year are cited, they should be lettered in sequence (1960a), (19606), etc. When papers are by more than two authors, ail the names should be recorded on first mention, e.g. Smith, Jones and Williams (1960); thereafter further reference should be to Smith et al. (1960). In the list of LITERATURE CITED, references must be placed in alphabetical order without serial numbering. The following standard form of citation should be used: SMITH, I. K., and FOWDEN, L., 1966. J. exp. Bot. 17, 750-61. All citations in the text should appear in the literature list and vice versa. Abbreviations of the titles of journals should be those of the World List of Scientific Periodi- cals (4th Edition), of which a selection of the most commonly required has been reprinted in Abbreviated Titles of Biological Journals (London: Institute of Biology). Abbreviations for the newer journals can be found in the New Periodical Titles supplements of the British Union- Catalogue of Periodicals. The list of literature cited must be typed double spaced throughout and checked thoroughly before submission. If the list is not in the correct form it will be returned to the author for amendment and publication of the paper may be delayed.

ILLUSTRATIONS Text-figures. These are expensive to print and their numbers should be kept to a minimum. The publication of many papers is delayed because figures have to be redrawn by the Press. This can be avoided if authors will comply exactly with the following instructions. Drawing should be made in black ink on Bristol board, tracing film or graph paper with faint ruling. Photocopies are not satisfactory for reproduction. Xerox copies or other suitable duplicates of figures should be supplied. In general it is unnecessary to supply diagrams more than twice the linear dimensions desired in the final reproduction. The maximum space available on a page is 215 x 150 mm (8-5 x 6 inches) and thus for a full page figure the original should not be larger than 430 x 300 mm (17 x 12 inches). Wherever possible smaller figures should be grouped to fill a page, in order to avoid the cost of larger numbers of small blocks. It is most important that lines and symbols should be drawn boldly enough to stand reduc- tion to the desired size. For graphs where reduction to one half in linear dimensions is intended a suitable thickness for the axis is 0-3 mm and for other lines 0-4 or 1-0 mm depending on the complexity of the graph. The preferred symbols are 0 O I A D A and should be used at this size for simple open graphs for reduction of one half. For more complex graphs smaller symbols of the following size should be used • o • • A A for the same reduction. The symbols x and + should be avoided. Lettering and shading or hatching should not be inserted in a figure but indicated on a self-locating transparent or translucent overlay. A typewritten, double-spaced list of legends of all figures must be supplied. Each legend should contain sufficient explanation to be meaningful without cross-referencing. The individual figures must be numbered clearly in pencil and should bear the name of the author.

PLATES Photographs for plates must be of high quality, printed on glazed paper, and should be supplied with dimensions not exceeding twice those required in the final reproduction. When several photographs are to be combined in a single plate they should be grouped to give a height-width ratio of 3:2 and mounted neatly on a white card base, leaving a narrow gap between each print. Irregular and asymmetrically distributed groups of photographs will not be accepted: it is always possible by adjusting the degree of enlargement to produce a pleasing layout. The maximum size of a plate in the journal is 215 x 150 mm (8-5 x 6 inches). It is recommended therefore that the over-all print size should not exceed 430 x 300 mm (17 x 12 inches), i.e. twice the size of a plate in the journal. Downloaded from https://academic.oup.com/jxb/issue/31/5 by guest on 23 September 2021 Individual plate figures should be lettered, A, B, C, etc., on the mount for insertion on the photograph by the block-maker. Other lettering, arrows, etc. may be put on the photograph by the author if he prefers, otherwise they should be indicated in the exact position required on a transparent or translucent self-locating overlay. On no account should any marks be made on the photograph itself. The mounts must carry the plate number in arable numerals and the name of the author. Citation in the text should tako the form Plate 1A, etc. A separate typewritten, double-spaced EXPLANATION OF PLATES must be supplied, setting out the legends for each photograph. A scale should be included in the picture wherever possible; otherwise the scale of the original should be stated in the EXPLANATION OF PLATES so that the final scale can be calculated.
